Welcome back.
This has been one of those weeks when a particular theme connected wide-ranging news stories with a coherent thread. The so-called Law of the Instrument was having a moment. Simply stated, “If all you have is a hammer, every problem looks like a nail”. That could be why utilities, in the face of growing calls for gas bans, see strategies like injecting hydrogen and “renewable natural gas” (RNG) into our current pipeline system that distributes fossil (natural) gas to homes and businesses, as a solution. Nice job, National Grid – “nailed” it!
It might also explain why private equity firms, rather than divesting from fossil fuels, continue pumping billions of dollars into projects that are exposing investors, including pensioners, to unknown financial risks as the planet burns and governments face escalating pressure to act.
The world is drowning in plastics. The solution? Make more! Two stories illustrate the pressures and the stakes for communities and the planet. A third story, describing fossil fuel industry efforts to chemically recycle plastics into… more fossil fuels… draws a line under our Law of the Instrument theme.
Sometimes it’s hard to tell what’s motivating powerful people, though. That’s where the Law of the Instrument seems a bit naive. A more applicable rule might be the one widely attributed to either novelist Upton Sinclair or journalist-curmudgeon H. L. Mencken: “It is difficult to get a man to understand something when his salary depends upon his not understanding it.”
We’re on thin ice whenever we ascribe motives to someone else’s actions, but “salary” (also wealth, power, influence, etc.) is a hard one not to settle on when observing industry resistance to the necessary and inevitable shift away from fossil fuels. Climate science lays out a very clear path to follow, and makes a strong case against continuing business as usual. But the fossil fuel industry continues to probe for opportunities to expand throughout Africa before countries there can leapfrog straight to clean generation. Utilities in this country knew for decades about coming climate impacts, yet chose to broadcast denial and sow confusion to buy more time to build profitable pipelines and power plants. The European Union is fully aware of the climate and ecosystem devastation resulting from their embrace of biomass energy, yet continue to classify it as a renewable resource.
It’s also easier to keep “not understanding” something when you can lock up pesky activists who try to get in your face about it. With help from the conservative American Legislative Exchange Council (Alec), anti-protest legislation is chilling actions against pipelines and other gas and oil expansion projects in 24 Republican-dominated states.
But let’s talk about the good stuff, starting with an explanation of the idea of a just transition to a green, sustainable economy. It’s a concept closely related to the environmental justice movement founded decades ago by Dr. Robert Bullard and others.
We took a tour through some exciting innovations that will help get us to that greener future. Clean energy is heading into deeper, windier waters with a big infusion of cash aimed at developing floating offshore wind. The Gulf of Maine and much of the West coast are too deep for today’s fixed turbine platforms.
Researchers at MIT and elsewhere announced initial success with a new kind of energy storage battery made from inexpensive, abundant materials, and promising excellent safety and durability performance. The importance of batteries in the modern grid can’t be overstated. A big reason California’s grid survived the recent record heatwaves is the massive batteries that have recently come online there.
In terms of powering electric transportation, engineers at Harvard are developing a solid state battery that appears to solve some of the reliability and lifecycle problems plaguing other design teams. Prototypes have shown an ability to last 10,000-lifetime cycles, and can charge in as little as three minutes.
We’re learning more about co-locating utility-scale solar installations on productive agricultural land. “Agrivoltaics” has come to a research corn field at Purdue, which is studying the impacts on crop production.
And finally, if the world can stop burning trees for energy and figure out how to reverse the decline of forests, sustainably-harvested timber could be used in mid-rise buildings as a substitute for steel and concrete – both huge carbon emitters. But we can’t see timber buildings as just another forest product to monetize, because that would further accelerate the decline of critical habitat.

GAS BANS
Hydrogen shouldn’t have a role in heating buildings
Green hydrogen should only be used where decarbonization is difficult
By Kyle Murray, CommonWealth Magazine | Opinion
September 11, 2022
NATIONAL GRID New England President Stephen Woerner recently wrote an op-ed noting how Greek architects practiced “a methodical, systematic style that appropriately balanced aspiration with sound architectural order for enduring results.” He compared this approach to National Grid’s planned strategies for injecting hydrogen and “renewable natural gas” (RNG) into our current pipeline system that distributes fossil (natural) gas to homes and businesses. Had the ancient Greek architects utilized such a short-sighted approach, the Parthenon would have long since crumbled to dust.
Far from the safe and successful heating source that National Grid describes, hydrogen is a highly combustible fuel that poses a significant safety risk in the context of residential and commercial buildings. In fact, the lion’s share of energy flowing through the gas system would still be made up of methane, a greenhouse gas that is more than 84 times as potent as carbon dioxide.
This methane can come in several forms – natural gas, “renewable natural gas,” or “synthetic natural gas” – but they all suffer from a common problem: producing, distributing, and using these fuels results in massive amounts of methane being released directly to the atmosphere. Updates to New York state’s greenhouse gas accounting for natural gas emissions revealed that over 47 percent of total emissions associated with natural gas consumption in New York are the result of methane leaks along the entire gas supply chain. Massachusetts has gas infrastructure that is in similar shape, if not worse.
In “Majority of US Urban Natural Gas Emissions Unaccounted for in Inventories,” a long-term study by Harvard scientists released in 2021, the authors found six times more methane leaking into the air around Boston than reported in the Massachusetts Greenhouse Gas Inventory compiled by the Massachusetts Department of Environmental Protection.
[…] We agree with National Grid that there are industries which are genuinely difficult to decarbonize, such as shipping and aviation, and will require creative solutions that include green hydrogen. However, that is a far cry from utilizing it for home heating, where better choices are available. It’s essentially the equivalent of saying you could heat your home using $20 bills as kindling in your living room fireplace. Sure, you may be able to do it, but is that really the wisest idea?

Progressive Revolt Against Manchin’s Energy Side Deal Could Snarl Government Funding
More than 70 House Democrats warned leadership against a special deal with West Virginia’s Democratic senator to win his Inflation Reduction Act support.
By Jonathan Nicholson, Huff Post
September 9, 2022
Seventy-two House Democrats, including several committee chairs, warned House leadership Friday not to agree to ease restrictions on new energy projects in the push to keep the federal government funded past Sept. 30.
The warning came in a letter organized by Rep. Raúl Grijalva (D-Ariz.), chair of the House Natural Resources Committee, and follows similar opposition by Sen. Bernie Sanders (I-Vt.) in the Senate. With Democrats holding paper-thin margins in each chamber, almost any defections on a temporary funding bill vote could cause big problems.
“In the face of the existential threats like climate change and MAGA extremism, House and Senate leadership has a greater responsibility than ever to avoid risking a government shutdown by jamming divisive policy riders into a must-pass continuing resolution,” Grijalva said in a statement about the letter.
“Permitting reform hurts already-overburdened communities, puts polluters on an even faster track, and divides the caucus. Now is just not the time,” he said.
Grijalva had been circulating the letter for weeks. Though it was signed by many members of the Congressional Progressive Caucus, 19 of the signatories were not CPC members, according to a Natural Resources Committee spokesperson, and 13 signers were members of the pro-business New Democrat Coalition. The chairs of the Financial Services, Armed Services and Budget committees were among those who signed.
To keep government agencies open past the end of the government’s fiscal year on Sept. 30, Congress must pass at least a temporary funding bill, known as a continuing resolution. Continuing resolutions generally just keep funding at existing levels and allow the government to operate through a specific date until a longer-term agreement can be reached. But as must-pass legislation, they can and often do become legislative Christmas trees for lawmakers to festoon with other bills that could not pass on their own.
Sen. Joe Manchin (D-W.Va.) reached an agreement with Senate Majority Leader Chuck Schumer (D-N.Y.) in the summer to pass changes in site permitting requirements for new energy projects, including pipelines, in exchange for Manchin’s support of the Democrats’ big climate and tax law, the Inflation Reduction Act.
But with the IRA now signed and Manchin’s leverage gone, Democratic leaders face a tough fight to make good on Manchin’s “sidecar” pact, especially after Manchin angered progressives earlier in the process by causing the climate and tax bill to be stripped of most of its social spending.

GREENING THE ECONOMY
What does ‘just transition’ really mean?
Here’s a primer on the term advocates use to describe the shift to a clean energy economy that benefits everyone.
By Alison F. Takemura, Canary Media
September 15, 2022
To address the climate crisis, the world must rapidly shift from fossil fuels to clean energy. For this transition to be a just one, we need to repair the harms of the fossil-fuel economy and equitably distribute the benefits of the clean energy economy, so that no one is left behind.
U.S. labor organizer Tony Mazzocchi is thought to have pioneered the concept of a just transition in response to the unfair treatment of workers as stronger environmental regulations throughout the 1970s and ’80s led to job losses in toxic U.S. industries.
For example, in 1987 the Environmental Protection Agency brokered an agreement with the Velsicol Chemical Corporation under which the company stopped selling chlordane and heptachlor, two pesticides linked to cancer, liver damage and seizures. Not long after, Velsicol closed one of its manufacturing plants, located in Marshall, Illinois, and laid off all of its hourly workers. The EPA designated the facility a Superfund site and dedicated more than $10 million to its cleanup. But the plant’s employees, Mazzocchi wrote in a rousing 1993 article, were “tossed onto the economic scrap heap.”
Mazzocchi supported stricter environmental laws but also championed workers’ rights, arguing that the government should provide workers transitioning out of toxic industries with broad financial and educational support.
[…] The phrase “just transition” quickly took root among environmental justice advocates, who expanded the term to include support for communities who bear a disproportionate burden of industrial and fossil fuel pollution while being denied commensurate economic benefits. Among these are the low-income communities of color dwelling in sacrifice zones, where toxic air inflicts health problems such as asthma and high rates of cancer.
Today, as the clean energy economy gains momentum, a just transition is a rallying cry for fossil fuel workers and front-line communities. It has even taken on global resonance as countries with economies that rely on coal and other fossil fuels call for assistance from wealthier nations to help them switch to clean energy.
Crucially, the concept is as relevant to new industries in the energy transition as it is to old ones. The manufacturers of clean energy technologies can also exploit workers and communities — take, for example, forced Uyghur labor in China used to produce polysilicon, a key component of solar panels, and the often-problematic ways in which minerals integral to clean energy technologies are mined. A just transition also means improving conditions for those who work in or live near these industries.

At 75, the Father of Environmental Justice Meets the Moment
The White House has pledged $60 billion to a cause Robert Bullard has championed since the late seventies. He wants guarantees that the money will end up in the right hands.
By Cara Buckley, New York Times
September 12, 2022
HOUSTON — He’s known as the father of environmental justice, but more than half a century ago he was just Bob Bullard from Elba, a flyspeck town deep in Alabama that didn’t pave roads, install sewers or put up streetlights in areas where Black families like his lived. His grandmother had a sixth grade education. His father was an electrician and plumber who for years couldn’t get licensed because of his race.
Now, more than four decades after Robert Bullard took an unplanned career turn into environmentalism and civil rights, the movement he helped found is clocking one of its biggest wins yet. Some $60 billion of the $370 billion in climate spending passed by Congress last month has been earmarked for environmental justice, which calls for equal environmental protections for all, the cause to which Dr. Bullard has devoted his life.
Some environmentalists have slammed the new legislation for allowing more oil and gas drilling, which generally hits disadvantaged communities the hardest. For Dr. Bullard, the new law is reason for celebration, but also caution. Too often, he said, federal money and relief funds are doled out inequitably by state and local governments, and away from people of color and poor communities, who are the most afflicted by pollution and most vulnerable to climate change. This might be a major moment for environmental justice, he said, but never before has so much been at stake.
“We need government watchdogs to ensure the money follows need,” Dr. Bullard said in a recent interview. “Climate change will make the inequities and disparities worse, and widen that gap. That’s why this time, we have to get this right.”

CLIMATE
Climate tipping points may be triggered even if warming peaks at 1.5C
By Fritz Habekuss, Bloomberg, in Boston Globe
September 9, 2022
The drought- and flood-stricken summer of 2022 has shown the impact of 1.1° Celsius of global warming — the amount that’s already occurred since pre-industrial times. Now a major scientific reassessment finds that several critical planetary systems are at risk of breaking beyond repair even if nations restrain warming to 1.5°C, the lower threshold stipulated by the Paris Agreement.
At that level of warming, coral reefs may die off, ice sheets in Greenland and the West Antarctic may melt and permafrost may abruptly thaw, according to a new paper in the journal Science.
The paper compiles evidence that major changes in the climate system, with massive environmental and societal consequences, are likely to occur at lower temperatures changes that previously assumed. It was written by a team of international scientists led by David Armstrong McKay of Stockholm University in Sweden and the University of Exeter in the UK.
“With this paper we show clearly that 1.5°C is not a climate limit to take lightly,” said Johan Rockström, one of the authors and director of the Potsdam Institute for Climate Impact Research in Germany. “Exceed it, and we are likely to trigger several tipping points.” The current trajectory of planetary warming is estimated to reach about 2.6°C.
Rockström and colleagues analyzed global and regional “tipping points”— thresholds beyond which climatic changes become self-perpetuating. The authors break them down by sensitivity to warming and offer confidence levels of low, medium and high in estimating the temperatures that will trigger them and the timescales in which they may happen.
Crossing these thresholds isn’t the planetary equivalent of suddenly driving off a cliff, from safety to danger. Rather, every increment of warming raises the odds of changes that become self-perpetuating. “Every tenth of a degree counts,” Rockström said.
At about 1.5°C some tipping points may be reached, including for the Greenland and West Antarctic ice sheets, accelerated thawing of boreal permafrost, and die-off of tropical coral reefs. But the authors “cannot rule out” that ice-sheet tipping points have already been passed and that some other tipping elements have minimum thresholds in range of 1.1°C to 1.5°C of warming.

CLEAN ENERGY
The Biden administration’s big new plans for floating offshore wind turbines
Floating turbines can go where no fixed-bottom turbine has gone before
By Justine Calma, The Verge
September 15, 2022
The Biden administration announced splashy new goals today aimed at positioning the US as a leader in the development of next-generation floating wind turbines. The announcement substantially expands Biden’s previous offshore wind ambitions by opening up new areas that traditional fixed-bottom turbines haven’t been able to reach.
Those turbines haven’t been able to conquer depths greater than 60 meters deep, where most of the world’s usable offshore wind resources can be found. Nearly 60 percent of the US’s offshore wind resources are at those depths. That includes much of the west coast, which has lagged behind the East Coast when it comes to offshore wind development because the Pacific Ocean drops off steeply close to the California and Oregon shore.
“Offshore wind is a critical part of our planning for the future. Some of the nation’s best potential for wind energy is along the southern coast of Oregon and the northern coast of California,” Oregon Governor Kate Brown said on a press call. “At the same time, the depth of our oceans off the West Coast and other technical challenges necessitate the development of floating offshore wind technology,” Brown said.
By 2035, the Biden administration wants to deploy 15 gigawatts of floating offshore wind capacity. It would be enough energy to power more than 5 million American homes, according to the Department of Interior (DOI). To make that happen, the Department of Energy (DOE) announced nearly $50 million of funding to research and develop floating offshore wind technologies.
The US Departments of Energy, Interior, Commerce, and Transportation jointly launched what they’re calling the “Floating Offshore Wind Shot.” They plan to work together to bring down the costs of floating offshore wind energy by 70 percent. The goal is for the technology to reach $45 per megawatt hour by 2035. For comparison, the average cost of fixed-bottom offshore wind projects in the US was $84 per megawatt-hour in 2021.

What the Western drought reveals about hydropower
By Jason Plautz, E&E News
September 13, 2022
The relentless Western drought that is threatening water supplies in the country’s largest reservoirs is exposing a reality that could portend a significant shift in electricity: Hydropower is not the reliable backbone it once was.
Utilities and states are preparing for a world with less available water and turning more to wind and solar, demand response, energy storage and improved grid connections. That planning has helped Western states keep the lights on this summer even in severe drought conditions.
Take California, which experienced record demand during a heat wave last week but did not have to impose any rolling blackouts. That’s despite the fact that hydropower — which on average makes up about 15 percent of the state’s power generation mix under normal conditions — has dipped by as much as half this summer.
“Obviously, water and energy are very much intertwined,” said Newsha Ajami, the director of urban water policy for Stanford University’s Water in the West initiative. “The interesting part here is that losing reliability in one is impacting reliability of the other. It’s hotter, it’s drier and people are using a lot more electricity as we rely on hydropower as one of our baseline power generators, but lake levels are lower.”
During the heat wave, officials timed releases from hydropower projects, which accounted for as much as 10 percent of the electricity for the state at some times of day, according to data from the California Independent System Operator. Elsewhere across the West, planners are accounting for growing demand while factoring in reductions in hydropower.
According to the 2018 National Climate Assessment, Southwestern hydropower and thermal power plant generation are “decreasing as a result of drought and rising temperatures.” A February study in the journal Water using World Wildlife Fund data found that by 2050, 61 percent of global hydropower dams will be at very high or extreme risk of droughts and/or floods.

ENERGY STORAGE
A new concept for low-cost batteries
Made from inexpensive, abundant materials, an aluminum-sulfur battery could provide low-cost backup storage for renewable energy sources.
By David L. Chandler, MIT News Office
August 24, 2022
As the world builds out ever larger installations of wind and solar power systems, the need is growing fast for economical, large-scale backup systems to provide power when the sun is down and the air is calm. Today’s lithium-ion batteries are still too expensive for most such applications, and other options such as pumped hydro require specific topography that’s not always available.
Now, researchers at MIT and elsewhere have developed a new kind of battery, made entirely from abundant and inexpensive materials, that could help to fill that gap.
The new battery architecture, which uses aluminum and sulfur as its two electrode materials, with a molten salt electrolyte in between, is described today in the journal Nature, in a paper by MIT Professor Donald Sadoway, along with 15 others at MIT and in China, Canada, Kentucky, and Tennessee.
“I wanted to invent something that was better, much better, than lithium-ion batteries for small-scale stationary storage, and ultimately for automotive [uses],” explains Sadoway, who is the John F. Elliott Professor Emeritus of Materials Chemistry.
In addition to being expensive, lithium-ion batteries contain a flammable electrolyte, making them less than ideal for transportation. So, Sadoway started studying the periodic table, looking for cheap, Earth-abundant metals that might be able to substitute for lithium. The commercially dominant metal, iron, doesn’t have the right electrochemical properties for an efficient battery, he says. But the second-most-abundant metal in the marketplace — and actually the most abundant metal on Earth — is aluminum. “So, I said, well, let’s just make that a bookend. It’s gonna be aluminum,” he says.
Then came deciding what to pair the aluminum with for the other electrode, and what kind of electrolyte to put in between to carry ions back and forth during charging and discharging. The cheapest of all the non-metals is sulfur, so that became the second electrode material. As for the electrolyte, “we were not going to use the volatile, flammable organic liquids” that have sometimes led to dangerous fires in cars and other applications of lithium-ion batteries, Sadoway says. They tried some polymers but ended up looking at a variety of molten salts that have relatively low melting points — close to the boiling point of water, as opposed to nearly 1,000 degrees Fahrenheit for many salts. “Once you get down to near body temperature, it becomes practical” to make batteries that don’t require special insulation and anticorrosion measures, he says.
The three ingredients they ended up with are cheap and readily available — aluminum, no different from the foil at the supermarket; sulfur, which is often a waste product from processes such as petroleum refining; and widely available salts. “The ingredients are cheap, and the thing is safe — it cannot burn,” Sadoway says.

Op-Ed: California’s giant new batteries kept the lights on during the heat wave
By Mike Ferry, Los Angeles Times
September 13, 2022
California just stared down its most extreme September heat event in history and survived better than expected — thanks in part to a new system of huge, grid-connected batteries.
The severity and duration of this latest climate-driven heat tested the state’s electricity grid like never before, setting records for power demand that pushed the supply to its limits. But the system held. The lights stayed on.
Additional tests lie ahead, for California and other states and nations. But after this round, California has a clear lesson for the world: Battery storage is a powerful tool for grids facing new strains from heat, cold, fire, flood or aging networks. And just as important, batteries are key to the zero-carbon future we need to avoid even greater stresses down the line.
Californians delivered big time this month when asked to cut use at critical moments during the crisis. But without storage capacity from new battery systems, reducing demand might not have been enough, and many consumers would have faced painful outages.
To be clear, the batteries that saved California this month are not like the ones in your phone, tablet and laptop, or even the bigger batteries in some homes ready to provide power during outages. The batteries that saved California are big — industrial big. Individual units weigh tens of thousands of pounds, and entire systems can be larger than a football field.
Many are installed at utility-scale solar fields, while “standalone” systems are strategically located throughout the state. These are not small add-ons to our electricity grid — they play the role of major power plants. In fact, some of the biggest batteries literally occupy the real estate and buildings that once housed fossil-fueled generators. And California has more batteries than anywhere else in the world, having grown its fleet more than 10-fold in just the last two years. Altogether, California’s batteries are now its biggest power plant.
For the vast majority of the year, these batteries play an essential role in stabilizing the grid, smoothing power flows and balancing variable energy. They also play a big part in leveling wholesale energy prices by charging up when electricity is cheap — usually during the midday “solar peak” — then discharging the energy back to the grid later that day, when prices are higher, a practice that keeps the market in check and reduces energy costs for Californians. But early this month, these batteries went from being everyday workhorses to crisis saviors.

BUILDING MATERIALS
‘Timber Cities’ Might Help Decarbonize the World
New research suggests that using wood for construction could avoid 100 gigatons of CO2 emissions through 2100, but building skylines of timber requires careful forest planning.
By Bob Berwyn, Inside Climate News
September 12, 2022
Buildings constructed with more wood, and less cement and steel, would help decarbonize the construction and housing industries in line with global goals to cut greenhouse gas emissions 50 percent by 2030 and reach net zero emissions by 2050, new research shows.
The paper, published Aug. 30 in Nature Communications, explains that building mid-rise wood dwellings to meet the demand from rapidly expanding urban populations could avoid about 100 gigatons of carbon dioxide emissions through 2100—about 10 percent of the reduction needed to cap global warming below 2 degrees Celsius.
“We do know we need to reach this net zero target as soon as possible,” said lead author Abhijeet Mishra, with the Potsdam Institute for Climate Impacts Research. “Reaching 1.5 degrees is getting quite dicey to achieve. An earlier paper from our colleagues really looked at how buildings can be a global carbon sink.” But that work did not answer the question of where the wood would come from. “The idea was to fill that gap,” he said.
The scale of wood construction envisioned would require about 555,000 square miles of additional tree plantations, an area slightly bigger than Alaska, on top of the 505,000 square miles of tree farms that exist globally today.

SITING IMPACTS OF RENEWABLE ENERGY RESOURCES
Research seeks ways to grow solar and crops together in the skeptical Corn Belt
By Sarah Bowman/Indianapolis Star, Brittney J. Miller/The Gazette and Joshua Rosenberg/The Lens, in Energy News Network
September 14, 2022
Acres of corn stand tall on both sides of a narrow country road in northwest Indiana. It’s late August and the corn is tasseling, its golden crown coated in dew droplets that are glinting off the morning summer sun. Then there is a different gleam on the horizon, one that’s brighter.
Sprouting out of the corn like a super crop are four arrays of solar panels standing 20 feet high and towering above the stalks growing below. Both corn and panels are harvesting the sun.
“Either way, they are storing solar energy,” said Mitch Tuinstra, a professor of plant breeding and genetics at Purdue University. “One is storing them as electrons and the other in the plants.”
Tuinstra is one of several Purdue faculty and graduate students studying these solar arrays on the university’s research field, just a few miles off campus in West Lafayette, Indiana.
Farmland is well suited for solar development of all kinds, for the same reasons it’s good for growing crops — it’s largely flat, drains well and gets lots of sun. What makes these Purdue research panels different is that they haven’t taken farmland out of production — they’re built overtop of the corn itself.
It’s a practice known as “agrivoltaics” or “agrisolar,” where active farming and solar happen in the same place instead of separately. The approach brings many complications that researchers are still trying to address — but they see big benefits in trying to hone in on best practices.
Farmers who want to lease their land for solar as an extra income source will reap even more economic benefits if that land stays in production — and some approaches to agrivoltaics may even help the crops themselves, researchers say.
“We want to see if we can devise systems that have minimal losses in terms of crop productivity, while maximizing their electricity output,” Tuinstra said.
Moreover, he said, researchers want to see how the co-location strategy could be a salve to a growing strain between solar and farming in the Corn Belt — where residents and towns are pushing back on what they see as industrialization in rural communities.

Harvard engineers develop solid-state battery with performance, reliability improvements
By Joey Klender, Teslarati
September 12, 2022
Engineers in the lab of Xin Li, an Associate Professor of Materials Science at Harvard’s John A. Paulson School of Engineering and Applied Sciences, have developed a new solid-state battery that is capable of 10,000-lifetime cycles and a charge rate as fast as three minutes. The revolutionary technology has brought in an exclusive grant from Harvard’s Office of Technology Development for Li’s startup Adden Energy, Inc., which will help develop cells with improvements in reliability and performance that could be used in future applications for electric vehicles.
Li, along with Fred Hu, William Fitzhugh, and Luhan Ye, all Ph.D. recipients at Harvard, founded Adden Energy in 2021. The startup was launched last year to help develop palm-sized pouch cells for various applications. The cells are essentially a trial run for future projects, which include a full-scale vehicle battery within the next three to five years.
“If you want to electrify vehicles, a solid-state battery is the way to go,” Li said in an interview with Harvard. “We set out to commercialize this technology because we do see our technology as unique compared to other solid-state batteries. We have achieved in the lab 5,000 to 10,000 charge cycles in a battery’s lifetime, compared with 2,000 to 3,000 charging cycles for even the best in class now, and we don’t see any fundamental limit to scaling up our battery technology. That could be a game changer.”
Solid-state batteries utilize a solid material to allow energy to flow from the cathode to the anode, instead of traditional lithium-ion cells, which utilize a liquid electrolyte solution. EV makers have not been able to switch to solid-state technology as of late due to its complex manufacturing processes. Additionally, researchers have not been able to find ideal solutions for the material it would utilize in the batteries, and this continues to be a pain point of the development.
However, Adden Energy’s grant from Harvard, along with a $5.15 million funding round earlier this year, will help develop the recently-successful palm-sized cell into an upstream process that will hopefully yield a new, full-scale EV battery. Adden’s cell achieved charging rates as fast as three minutes and over 10,000 cycles in its lifetime. It also displayed high energy density and stability that was incredibly more predictable than lithium-ion cells.
Li, along with other Adden founders, all maintain that developing a solid-state cell could help improve affordability, availability, and the overall EV market share.

ELECTRIC UTILITIES
America’s electric utilities spent decades spreading climate misinformation
Utilities knew about climate change as early as the 1960s and misled the public in order to continue turning a profit.
By Zoya Teirstein, Grist
September 7, 2022
America’s electric utilities were aware as early as the 1960s that the burning of fossil fuels was warming the planet, but, two decades later, worked hand in hand with oil and gas companies to “promote doubt around climate change for the sake of continued … profits,” finds a new study published in the journal Environmental Research Letters.
The research adds utility companies and their affiliated groups to the growing list of actors that spent years misleading the American public about the threat of climate change. Over the past half decade, oil companies like BP and ExxonMobil have had to defend themselves in court against cities, state attorneys general, youth activists, and other entities who allege the world’s fossil fuel giants knew about the existence of climate change as far back as 1968, yet chose to ignore the information and launch disinformation campaigns. Recent investigations show the coal industry did something similar, as did fossil fuel-funded economists.
But while the role Big Oil played in misleading the public has been widely publicized, utilities’ culpability has largely flown under the radar. So researchers at the University of California, Santa Barbara began collecting and analyzing public and private records kept by organizations within the utility industry.
[…] Emily Williams, a postdoctoral student at the University of California, Santa Barbara and the lead author of the study, told Grist that the documents provide a sense of when the utility industry’s climate denial began — and how it has evolved over time. The takeaways are stark: Utilities became aware of the dangers of burning fossil fuels in the 1960s and ‘70s, and acknowledged the risks it posed for the industry. “If [climate change turned] out to be of major concern, then fossil fuel combustion will be essentially unacceptable,” an article by the Electric Power Research Institute stated in 1977. But for the next two decades, those same utilities promoted false doubt about humanity’s role in climate change and tried to delay action. An article from the Edison Electric Institute published in 1989 said that, “any plan calling for urgent and extreme action to reduce utility CO2 emissions is premature at best.”
By the 2000s, the industry and its related groups had publicly acknowledged the scientific consensus that humans are largely responsible for warming the planet, but shifted from a strategy of denial to one of delay. The sector has spent some $500 million over the past two decades lobbying Congress and state legislatures against renewable energy and climate policies.

FOSSIL FUEL INDUSTRY
Exclusive: African civil society speaks out against continent’s $400bn gas trap
Civil society groups argue that $400bn being spent on natural gas will not benefit the African people, and would be better spent on the new green economy.
By Nick Ferris, Energy Monitor
September 14, 2022
Civil society groups have spoken out against plans to develop new gas infrastructure across Africa, as an investigation from Energy Monitor reveals that $400bn worth of new projects are on the way.
The figure is based on a new analysis of exclusive datasets provided by GlobalData, Energy Monitor’s parent company, and includes planned upstream, midstream and downstream developments. In all, it is worth around 15% of the entire GDP of Africa in 2021.
“The $400bn pipeline poses major threats to Africa’s energy sovereignty,” says Amos Wemanya from the Kenya-based think tank Power Shift Africa. “Beyond accelerating the already run-away climate crisis, investing in fossil fuels infrastructure such as pipelines risks leaving African economies with stranded assets and debts to repay.”
Avena Jacklin, from the South Africa-based environmental NGO Groundwork, adds that developing Africa’s gas pipeline will only benefit “European countries looking for alternative gas supplies, and oil and gas multinational corporations looking to make huge profits”.
“The IEA’s net-zero 2050 report states that if the world is to avoid irreversible, catastrophic climate change, no new oil and gas fields should be developed,” she said.
Debate rages over whether gas can be considered a ‘transition fuel’ for Africa. On the one hand, the remaining global carbon budget is so limited scientists now stress there is no scope for licensing new gas extraction if we are to avoid catastrophic climate change. Renewables are also now a cheaper source of power in most markets.
At the same time, with more than 600 million people still lacking access to electricity and 930 million people lacking access to clean cooking fuels, Africa’s development needs remain profound. Many governments are keen to extract gas to bring in export revenue, while gas power plants represent a route to reliable grid power. Advocates for gas also point out that Africa is responsible for just 4% of annual global greenhouse gas emissions, and gas produces around half the emissions of coal when burnt.
Many African leaders are calling on rich nations to continue funding gas extraction and gas-fired power stations in their countries. At an August 2022 summit, the African Union (AU) called on nations to “continue to deploy all forms of its abundant energy resources including renewable and non-renewable energy to address energy demand”. It added that financing gas continues to make sense “in the short to medium term”.
However, many civil society groups take issue with this point of view.
“The AU’s position that Africa needs gas to develop is only intended to benefit developed countries and certain vested interests in Africa,” says Charity Migwi, a Kenya-based campaigner with grassroots environmental movement 350Africa. “It serves to delay and threaten the potential investments into clean, affordable, decentralised renewable energy for the people.
“Africa’s development relies on a rapid shift away from harmful fossil fuels and towards a sustainable energy future.”
Groundwork’s Jacklin agrees: “Investing $400bn in fossil fuel infrastructure means misdirecting limited resources that are needed to enable development of clean, affordable, easily deployable renewable energy systems to end Africa’s energy hunger.”

BIOMASS
EU votes to curb tree burning for fuel, but falls short of phasing it out
By Jim Regan, Renew Economy
September 15, 2022
The European Union is moving to limit the damage inflicted on the climate by its own biomass policies after voting for an exclusion of primary woody biomass subsidies and capping the amount that can count as renewable energy, drawing a mixed reaction from conservationists.
The vote by members of the European Parliament revises the EU’s Renewable Energy Directive, which critics have claimed encourages member states to burn more trees in the name of climate action, despite this practice increasing harmful emissions.
While the EU Parliament’s environment committee previously agreed to end support for burning trees entirely, the latest vote is seen as a compromise that will still regard woody biomass as a source of renewable energy.
[…] In the EU, alone, scientists estimate that carbon emissions from burning woody biomass are now over 400 million metric tonnes per year – roughly equal to the combined CO2 emissions of Poland and Italy.
“EU bioenergy policies are a serious climate threat and for years have been a stain on EU climate leadership, but today marks a turning point for the first time an EU institution has recognised that burning trees might not be the best way of getting off fossil fuels and stopping runaway climate change.” said Alex Mason, head of EU climate and energy policy at WWF European Policy Office.
“But there’s still some way to go. A majority in the parliament is still in thrall to the biofuels lobby, and can’t seem to understand that growing crops to burn just increases emissions compared to fossil fuels,” Mason said.
Conservationists have also voiced concerns that the outcome of Wednesday’s vote will mean that the EU continues to promote the burning of forest wood as a source of renewable energy to member states.
“Burning trees and crops for energy destroys nature and exacerbates the climate crisis,” said Ariel Brunner, head of policy for Birdlife Europe. “It should not be supported as a renewable energy.”
He said it was “disappointing” that the parliament “agreed to a weak compromise” that does little to protect tree populations.

Judge Tosses Air Permits For $9.4 Billion Louisiana Plastics Plant
The sharply worded ruling dismantled the state Department of Environmental Quality’s rationale for permits that would have allowed Formosa Plastics to emit more than 800 tons of toxic pollution a year into predominantly Black St. James Parish. “People’s lives are worth more than plastic,” says one activist.

Citing a litany of failures by Louisiana environmental regulators, including their analyses of environmental justice and climate impacts, a state judge has thrown out the air permits for a giant plastics manufacturing complex to be located 55 miles west of New Orleans.
The decision is another major blow to the $9.4 billion Formosa Plastics complex, which in 2020 was forced, following a separate lawsuit, to revisit a Clean Water Act permit that had been issued, and then suspended, by the U.S. Army Corps of Engineers, which had put the project on hold.
When the complex and its planned 10-year buildout was announced by Formosa in 2018, it was hailed by Gov. John Bel Edwards as an economic boon and source of 1,200 jobs. But the complex, to be built on 2,400 acres along the Mississippi River in St. James Parish, has also faced fierce opposition from local and national environmental groups fighting to curtail greenhouse gas emissions amid a climate crisis.
Point by point in a sharply worded 34-page ruling made public on Wednesday, 19th Judicial District Judge Trudy White dismantled the rationale for some 15 air permits that the state Department of Environmental Quality (DEQ) issued for the massive complex. The permits would have allowed Formosa to emit more than 800 tons per year of toxic pollution into a predominantly Black, low-income community, and send as much as 13.6 million tons per year of greenhouse gases into the atmosphere, an amount roughly equivalent to 3.5 coal-fired power plants.
“I think this is the beginning of a change,” said Sharon Lavigne, founder and president of RISE St. James, one of several local and national environmental groups that brought the lawsuit in 2019. “It’s a beginning. It’s a new way this industry is going to do business. It will make DEQ think twice” in future permit applications.
In the end, she said, the ruling “is about saving our lives.”
In Louisiana, the petrochemical industry “is used to getting what it wants,” said Corinne Van Dalen, senior attorney at Earthjustice, the nonprofit legal organization that represented plaintiff groups, and the lead attorney on the case. “This is how they do their work and this decision dismantles that.”

The Titans of Plastic
Pennsylvania becomes the newest sacrifice zone for America’s plastic addiction.
By Kristina Marusic, Environmental Health News
September 15, 2022
During the summer of 2018, two of the largest cranes in the world towered over the Ohio River. The bright-red monoliths were brought in by the multi-national oil and gas company Shell to build an approximately 800-acre petrochemical complex in Potter Township, Pennsylvania—a community of about 500 people. In the months that followed, the construction project would require remediating a brownfield, rerouting a highway, and constructing an office building, a laboratory, a fracked-gas power plant, and a rail system for more than 3,000 freight cars.
The purpose of Shell’s massive complex wasn’t simply to refine gas. It was to make plastic.
Five years after construction began at the site, Shell’s complex, which is one of the biggest state-of-the-art ethane cracker plants in the world, is set to open. An important component of gas and a byproduct of oil refinery operations, ethane is an odorless hydrocarbon that, when heated to an extremely high temperature to “crack” its molecules apart, produces ethylene; three reactors combine ethylene with catalysts to create polyethylene; and a 2,204-ton, 285-foot-tall “quench tower” cools down the cracked gas and removes pollutants. That final product is then turned into virgin plastic pellets. Estimates suggest that a plant the size of the Potter Township petrochemical complex would use ethane from as many as 1,000 fracking wells.
Shell ranks in the top 10 among the 90 companies that are responsible for two-thirds of historic greenhouse gas emissions. Its Potter Township cracker plant is expected to emit up to 2.25 million tons of climate-warming gases annually, equivalent to approximately 430,000 extra cars on the road. It will also emit 159 tons of particulate matter pollution, 522 tons of volatile organic compounds, and more than 40 tons of other hazardous air pollutants. Exposure to these emissions is linked to brain, liver, and kidney issues; cardiovascular and respiratory disease; miscarriages and birth defects; and childhood leukemia and cancer. Some residents fear that the plant could turn the region into a sacrifice zone: a new “Cancer Alley” in Beaver County, Pennsylvania.
“I’m worried about what this means for our air, which is already very polluted, and for our drinking water,” said Terrie Baumgardner, a retired English professor and a member of the Beaver County Marcellus Awareness Community, the main local advocacy group that fought the plant. Baumgardner, who is also an outreach coordinator at the Philadelphia-based nonprofit environmental advocacy group Clean Air Council, lives near the ethane cracker. In addition to sharing an airshed with the plant, she is one of the approximately 5 million people whose drinking water comes from the Ohio River watershed. When Shell initially proposed the petrochemical plant in 2012, she and other community advocates tried their best to stop it.
And the plant’s negative impact will go far beyond Pennsylvania. Shell’s ethane cracker relies on a dense network of fracking wells, pipelines, and storage hubs. It’s one of the first US ethane crackers to be built outside the Gulf of Mexico, and one of five such facilities proposed throughout Appalachia’s Ohio River Valley, which stretches through parts of Ohio, Indiana, Kentucky, Pennsylvania, and West Virginia. If the project is profitable, more like it will follow—dramatically expanding the global market for fossil fuels at a time when the planet is approaching the tipping point of the climate crisis.
For the residents who live nearby, Shell’s big bet on plastic represents a new chapter in the same story that’s plagued the region for decades: An extractive industry moves in, exports natural resources at a tremendous profit—most of which flow to outsiders—and leaves poverty, pollution, and illness in its wake. First came the loggers, oil barons, and coal tycoons. Then there were the steel magnates and the fracking moguls.
Now it’s the titans of plastic.

PLASTICS RECYCLING
A New Plant in Indiana Uses a Process Called ‘Pyrolysis’ to Recycle Plastic Waste. Critics Say It’s Really Just Incineration
After two years, Brightmark Energy has yet to get the factory up and running. Environmentalists say pyrolysis requires too much energy, emits greenhouse gases and pollutants, and turns plastic waste into new, dirty fossil fuels.
By James Bruggers, Inside Climate News
September 11, 2022
ASHLEY, Indiana—The bales, bundles and bins of plastic waste are stacked 10 feet high in a shiny new warehouse that rises from a grassy field near a town known for its bright yellow smiley-face water tower.
Jay Schabel exudes the same happy optimism. He’s president of the plastics division of Brightmark Energy, a San Francisco-based company vying to be on the leading edge of a yet-to-be-proven new industry—chemical recycling of plastic.
Walking in the warehouse among 900 tons of a mix of crushed plastic waste in late July, Schabel talked about how he has worked 14 years to get to this point: Bringing experimental technology to the precipice of what he anticipates will be a global, commercial success. He hopes it will also take a bite out of the plastic waste that’s choking the planet.
[…] But the company, which broke ground in Ashley in 2019, has struggled to get the plant operating on a commercial basis, where as many as 80 employees would process 100,000 tons of plastic waste each year in a round-the-clock operation.
Schabel said that was to change in August, with its first planned commercial shipment of fuel to its main customer, global energy giant BP. But a company spokesman said in mid-August that the date for the first commercial shipment had been pushed back to September, with “full-scale operation…extending through the end of the year and into 2023.”
[…] Its business model must contend with plastics that were never designed to be recycled. U.S. recycling policies are dysfunctional, and most plastics end up in landfills and incinerators, or on streets and waterways as litter.
Environmental organizations with their powerful allies in Congress are fighting against chemical recycling and the technology found in this plant, known as pyrolysis, in particular, because they see it as the perpetuation of climate-damaging fossil fuels.
“The problem with pyrolysis is we should not be producing more fossil fuels,” said Judith Enck, a former regional director of the U.S. Environmental Protection Agency and the founder and executive director of Beyond Plastics, an environmental group. “We need to be going in the opposite direction. Using plastic waste as a feedstock for fossil fuels is doubling the damage to the environment because there are very negative environmental impacts from the production, disposal and use of plastics.”
