The unregulated carbon dioxide removal industry is calling on the U.S. government to implement standards and regulations to boost transparency and confidence in the sector that's been flooded with billions of dollars in federal funding and private investment.

A report Wednesday by the Carbon Removal Alliance, a nonprofit representing the industry, outlined recommendations to improve monitoring, reporting, and verification. Currently the only regulations in the U.S. are related to safety of these projects. Some of the biggest industry players, including Heirloom and Climeworks, are alliance members.

“I think it’s rare for an industry to call for regulation of itself and I think that is a signal of why this is so important,” said Giana Amador, executive director of the alliance. Amador said monitoring, reporting and verification are like “climate receipts” that confirm the amount of carbon removed as well as how long it can actually be stored underground.

Without federal regulation, she said “it really hurts competition and it forces these companies into sort of a marketing arms race instead of being able to focus their efforts on making sure that there really is a demonstrable climate impact.”

The nonprofit defines carbon removal as any solution that captures carbon dioxide from the atmosphere and stores it permanently. One of the most popular technologies is direct air capture, which filters air, extracts carbon dioxide and puts it underground.

The Inflation Reduction Act and the Bipartisan Infrastructure Law have provided around $12 billion for carbon management projects in the U.S. Some of this funding supports the development of four Regional Direct Air Capture Hubs at commercial scale that will capture at least 1 million tons of carbon dioxide annually. Two hubs are slated to be built in Texas and Louisiana.

Some climate scientists say direct air capture is too expensive, far from being scaled and can be used as an excuse by the oil and gas industry to keep polluting.

Gernot Wagner, a climate economist at Columbia Business School at Columbia University, said this is the “moral hazard” of direct air capture — removing carbon from the atmosphere could be utilized by the oil and gas industry to continue polluting.

“It does not mean that the underlying technology is not a good thing,” said Wagner. Direct air capture “decreases emissions, but in the long run also extends the life of any one particular coal plant or gas plant.”

In 2023, Occidental Petroleum Corporation purchased the direct air capture company, Carbon Engineering Ltd, for $1.1 billion. In a news release, Occidental CEO Vicki Hollub said, “Together, Occidental and Carbon Engineering can accelerate plans to globally deploy (the) technology at a climate-relevant scale and make (it) the preferred solution for businesses seeking to remove their hard-to-abate emissions.”

Jonathan Foley, executive director of Project Drawdown, doesn't consider carbon dioxide removal technologies to be a true climate solution.

“I do welcome at least some interventions from the federal government to monitor and verify and evaluate the performance of these proposed carbon removal schemes, because it’s kind of the Wild West out there,” said Foley.

“But considering it can cost ten to 100 times more to try to remove a ton of carbon rather than prevent it, how is that even remotely conscionable to spend public dollars on this kind of stuff?” he said.

Katharine Hayhoe, chief scientist of The Nature Conservancy and a distinguished professor at Texas Tech University, said standards for the direct carbon capture industry “are very badly needed” because of the level of government subsidies and private investment. She said there's no single fix for the climate crisis, and many strategies are needed.

Hayhoe said these include improving the efficiency of energy systems, transitioning to clean energy, weaning the world off fossil fuels and maintaining healthy ecosystems to trap carbon dioxide. On the other hand, she said, carbon removal technologies are “very high hanging fruit.”

"It takes a lot of money and a lot of energy to get to the top of the tree. That’s the carbon capture solution,” said Hayhoe. “Of course we need every fruit on the tree. But doesn’t it make sense to pick up the fruit on the ground, to prioritize that?”

Other climate scientists are entirely opposed to this technology.

“It should be banned,” said Mark Z. Jacobson, professor of civil and environmental engineering at Stanford University.

Carbon removal technologies indirectly increase the amount of carbon dioxide in the atmosphere, Jacobson said. The reason, he said, is that even in cases where direct air capture facilities are powered by renewable energy, the clean energy is being used for carbon removal instead of replacing a fossil fuel source.

“When you just look at the capture equipment, you get a (carbon) reduction," Jacobson said. "But when you look at the bigger system, you’re increasing.”

US awards $3B for EV battery production in Texas, other states

charging up

The Biden administration is awarding over $3 billion to U.S. companies to boost domestic production of advanced batteries and other materials used for electric vehicles, part of a continuing push to reduce China’s global dominance in battery production for EVs and other electronics.

The grants will fund a total of 25 projects in 14 states, including Texas, as well as Ohio, South Carolina, Michigan, North Carolina, and Louisiana.

The grants announced Friday mark the second round of EV battery funding under the bipartisan infrastructure law approved in 2021. An earlier round allocated $1.8 billion for 14 projects that are ongoing. The totals are down from amounts officials announced in October 2022 and reflect a number of projects that were withdrawn or rejected by U.S. officials during sometimes lengthy negotiations.

The money is part of a larger effort by President Joe Biden and Vice President Kamala Harris to boost production and sales of electric vehicles as a key element of their strategy to slow climate change and build up U.S. manufacturing. Companies receiving awards process lithium, graphite or other battery materials, or manufacture components used in EV batteries.

“Today’s awards move us closer to achieving the administration’s goal of building an end-to-end supply chain for batteries and critical minerals here in America, from mining to processing to manufacturing and recycling, which is vital to reduce China’s dominance of this critical sector,'' White House economic adviser Lael Brainard said.

The Biden-Harris administration is "committed to making batteries in the United States that are going to be vital for powering our grid, our homes and businesses and America’s iconic auto industry,'' Brainard told reporters Thursday during a White House call.

The awards announced Friday bring to nearly $35 billion total U.S. investments to bolster domestic critical minerals and battery supply chains, Brainard said, citing projects from major lithium mines in Nevada and North Carolina to battery factories in Michigan and Ohio to production of rare earth elements and magnets in California and Texas.

“We’re using every tool at our disposal, from grants and loans to allocated tax credits,'' she said, adding that the administration's approach has leveraged more $100 billion in private sector investment since Biden took office.

In recent years, China has cornered the market for processing and refining key minerals such as lithium, rare earth elements and gallium, and also has dominated battery production, leaving the U.S. and its allies and partners "vulnerable,'' Brainard said.

The U.S. has responded by taking what she called “tough, targeted measures to enforce against unfair actions by China.” Just last week, officials finalized higher tariffs on Chinese imports of critical minerals such as graphite used in EV and grid-storage batteries. The administration also has acted under the 2022 climate law to incentivize domestic sourcing for EVs sold in the U.S. and placed restrictions on products from China and other adversaries labeled by the U.S. as foreign entities of concern.

"We're committed to making batteries in the United States of America,'' Energy Secretary Jennifer Granholm said.

If finalized, awards announced Friday will support 25 projects with 8,000 construction jobs and over 4,000 permanent jobs, officials said. Companies will be required to match grants on a 50-50 basis, with a minimum $50 million investment, the Energy Department said.

While federal funding may not be make-or-break for some projects, the infusion of cash from the infrastructure and climate laws has dramatically transformed the U.S. battery manufacturing sector in the past few years, said Matthew McDowell, associate professor of engineering at Georgia Institute of Technology.

McDowell said he is excited about the next generation of batteries for clean energy storage, including solid state batteries, which could potentially hold more energy than lithium ion.

Houston-area selected among 7 regions for $7B federal hydrogen hub investment

HyVelocity

Not only has a Houston-area project been announced as one of the seven regions to receive a part of the $7 billion in Bipartisan Infrastructure Law funding to advance domestic hydrogen production — but the Bayou City is getting one of the largest pieces of the pie.

President Biden and Energy Secretary Jennifer Granholm named the seven regions to receive funding in a White House statement today. The Gulf Coast's project, HyVelocity Hydrogen Hub, will receive up to $1.2 billion — the most any hub will receive, per the release.

“As I’ve stated repeatedly over the past years, we are uniquely positioned to lead a transformational clean hydrogen hub that will deliver economic growth and good jobs, including in historically underserved communities," Houston Mayor Sylvester Turner says in a news release. "HyVelocity will also help scale up national and world clean hydrogen economies, resulting in significant decarbonization gains. I’d also like to thank all the partners who came together to create HyVelocity Hub in a true spirit of public-private collaboration.”

Backed by industry partners AES Corporation, Air Liquide, Chevron, ExxonMobil, Mitsubishi Power Americas, Ørsted, and Sempra Infrastructure, the HyVelocity Hydrogen Hub will connect more than 1,000 miles of hydrogen pipelines, 48 hydrogen production facilities, and dozens of hydrogen end-use applications across Texas and Southwest Louisiana. The hub is planning for large-scale hydrogen production through both natural gas with carbon capture and renewables-powered electrolysis.

The project is spearheaded by GTI Energy and other organizing participants, including the University of Texas at Austin, The Center for Houston’s Future, Houston Advanced Research Center, and around 90 other supporting partners from academia, industry, government, and beyond.

“Prioritizing strong community engagement and demonstrating an innovation ecosystem, the HyVelocity Hub will improve local air quality and create equitable access to clean, reliable, affordable energy for communities across the Gulf Coast region,” says Paula A. Gant, president and CEO of GTI Energy, in a news release.

According to the White House's announcement, the hub will create 45,000 direct jobs — 35,000 in construction jobs and 10,000 permanent jobs. The other selected hubs — and the impact they are expected to have, include:

  • Tied with HyVelocity in terms of funding amount, the California Hydrogen Hub — Alliance for Renewable Clean Hydrogen Energy Systems (ARCHES) — will also receive up to $1.2 billion to create 220,000 direct jobs—130,000 in construction jobs and 90,000 permanent jobs. The project is expected to target decarbonizing public transportation, heavy duty trucking, and port operations.
  • The Midwest Alliance for Clean Hydrogen (MachH2), spanning Illinois, Indiana, and Michigan, will receive up to $1 billion. This region's efforts will be directed at optimizing hydrogen use in steel and glass production, power generation, refining, heavy-duty transportation, and sustainable aviation fuel. It's expected to create 13,600 direct jobs—12,100 in construction jobs and 1,500 permanent jobs.
  • Receiving up to $1 billion and targeting Washington, Oregon, and Montana, the Pacific Northwest Hydrogen Hub — named PNW H2— will produce clean hydrogen from renewable sources and will create over 10,000 direct jobs—8,050 in construction jobs and 350 permanent jobs.
  • The Appalachian Regional Clean Hydrogen Hub (ARCH2), which will be located in West Virginia, Ohio, and Pennsylvania, will tap into existing infrastructure to use low-cost natural gas to produce low-cost clean hydrogen and permanently and safely store the associated carbon emissions. The project, which will receive up to $925 million, will create 21,000 direct jobs—including more than 18,000 in construction and more than 3,000 permanent jobs.
  • Spanning Minnesota, North Dakota, and South Dakota, the Heartland Hydrogen Hub will receive up to $925 million and create around 3,880 direct jobs–3,067 in construction jobs and 703 permanent jobs — to decarbonize the agricultural sector’s production of fertilizer, decrease the regional cost of clean hydrogen, and advance hydrogen use in electric generation and for cold climate space heating.
  • Lastly, the Mid-Atlantic Clean Hydrogen Hub (MACH2), which will include Pennsylvania, Delaware, and New Jersey, hopes to repurposing historic oil infrastructure to develop renewable hydrogen production facilities from renewable and nuclear electricity. The hub, which will receive up to $750 million, anticipates creating 20,800 direct jobs—14,400 in construction jobs and 6,400 permanent jobs.

These seven clean hydrogen hubs are expected to catalyze more than $40 billion in private investment, per the White house, and bring the total public and private investment in hydrogen hubs to nearly $50 billion. Collectively, they aim to produce more than three million metric tons of clean hydrogen annually — which reaches nearly one third of the 2030 U.S. clean hydrogen production goal. Additionally, the hubs will eliminate 25 million metric tons of carbon dioxide emissions from end uses each year. That's roughly equivalent to annual emissions of over 5.5 million gasoline-powered cars.

“Unlocking the full potential of hydrogen—a versatile fuel that can be made from almost any energy resource in virtually every part of the country—is crucial to achieving President Biden’s goal of American industry powered by American clean energy, ensuring less volatility and more affordable clean energy options for American families and businesses,” U.S. Secretary of Energy Jennifer M. Granholm says in the release. “With this historic investment, the Biden-Harris Administration is laying the foundation for a new, American-led industry that will propel the global clean energy transition while creating high quality jobs and delivering healthier communities in every pocket of the nation.”

HyVelocity has been a vision amongst Houston energy leaders for over a year, announcing its bid for regional hydrogen hub funding last November. Another Houston-based clean energy project was recently named a semi-finalist for National Science Foundation funding.

“We are excited to get to work making HyVelocity come to life,” Brett Perlman, president and CEO of Center for Houston’s Future, says in the release. “We look forward to spurring economic growth and development, creating jobs, and reducing emissions in ways that will benefit local communities and the Gulf Coast region as a whole. HyVelocity will be a model for creating a clean hydrogen ecosystem in an inclusive and equitable manner.”

USDA announces $1.4 billion solar, battery energy project in rural South Texas to cut climate pollution

coming soon

The United States Department of Agriculture recently announced that San Miguel Electric Cooperative Inc., located in Christine, Texas, in Atascosa County, just outside of San Antonio, will transition its operations to produce 600 megawatts of energy using solar panels and a battery energy storage system (BESS).

The project is expected to reduce climate pollution by 1.8 tons annually, equivalent to removing 446,000 cars from the road each year, says USDA.

The project with the San Miguel Electric Cooperative plans to use more than $1.4 billion investment to procure 600 megawatts of renewable energy through solar voltaic panels and a battery energy storage system to power 47 counties across rural South Texas. The clean project also hopes to support as many as 600 jobs.

This is part of the over $4.37 billion in clean energy investments through the United States Department of Agriculture’s (USDA) Empowering Rural America (New ERA) Program, which has rural electric cooperatives supporting the economy via job creation, lowering electricity costs for businesses and families and reducing climate pollution. The New ERA was made possible by President Joe Biden’s Inflation Reduction Act, which was the largest investment in rural electrification since President Franklin Delano Roosevelt signed the Rural Electrification Act into law in 1936.

San Miguel plans to convert its operations to a 400-megawatt solar generation facility and 200-megawatt battery storage facility, and the transition should be complete by 2027. Currently, San Miguel produces 391 megawatts of electricity through a contract with South Texas Electric Cooperative (STEC).

“USDA is committed to enhancing the quality of life and improving air and water in our rural communities,” Secretary Tom Vilsack says in a news release. “The Inflation Reduction Act’s historic investments enable USDA to partner with rural electric cooperatives to strengthen America’s energy security and lower electricity bills for hardworking families, farmers and small business owners.”

UH researchers develop breakthrough material to boost efficiency of sodium-ion batteries

future of batteries

A research lab at the University of Houston has developed a new type of material for sodium-ion batteries that could make them more efficient and boost their energy performance.

Led by Pieremanuele Canepa, Robert Welch assistant professor of electrical and computer engineering at UH, the Canepa Research Laboratory is working on a new material called sodium vanadium phosphate, which improves sodium-ion battery performance by increasing the energy density. Energy density is the amount of energy stored per kilogram, and the new material can do so by more than 15 percent. With a higher energy density of 458 watt-hours per kilogram — compared to the 396 watt-hours per kilogram in older sodium-ion batteries — this material brings sodium technology closer to competing with lithium-ion batteries, according to the researchers.

The Canepa Lab used theoretical expertise and computational methods to discover new materials and molecules to help advance clean energy technologies. The team at UH worked with the research groups headed by French researchers Christian Masquelier and Laurence Croguennec from the Laboratoire de Reáctivité et de Chimie des Solides, which is a CNRS laboratory part of the Université de Picardie Jules Verne, in Amiens France, and the Institut de Chimie de la Matière Condensée de Bordeaux, Université de Bordeaux, Bordeaux, France for the experimental work on the project.

The researchers then created a battery prototype using the new materia sodium vanadium phosphate, which demonstrated energy storage improvements. The material is part of a group called “Na superionic conductors” or NaSICONs, which is made to let sodium ions move in and out of the battery during charging and discharging.

“The continuous voltage change is a key feature,” Canepa says in a news release. “It means the battery can perform more efficiently without compromising the electrode stability. That’s a game-changer for sodium-ion technology.”

The synthesis method used to create sodium vanadium phosphate may be applied to other materials with similar chemistries, which could create new opportunities for advanced energy storage. A paper of this work was published in the journal Nature Materials.

"Our goal is to find clean, sustainable solutions for energy storage," Canepa adds. "This material shows that sodium-ion batteries can meet the high-energy demands of modern technology while being cost-effective and environmentally friendly."
