The four companies are among 24 semifinalists in the agency’s Carbon Dioxide Removal Purchase Pilot Prize program that were chosen to receive a total of $1.2 million for their commercial-scale CO2 removal technology.

Four Houston companies have received $50,000 each from the U.S. Department of Energy to further develop their carbon dioxide removal technology.

The four companies are among 24 semifinalists in the agency’s Carbon Dioxide Removal Purchase Pilot Prize program that were chosen to receive a total of $1.2 million for their commercial-scale CO2 removal technology.

The funding comes in the form of the Department of Energy’s purchase of CO2 removal credits.

“The Carbon Dioxide Removal Purchase Prize is a first-of-a-kind initiative to catalyze the market for high-quality CO2 removal credits, helping jumpstart a critical decarbonization tool,” U.S. Energy Secretary Jennifer Granholm says in a news release.

The Carbon Dioxide Removal Purchase Pilot Prize project will provide up to $35 million in cash awards. The 24 semifinalists will be whittled down to as many as 10 finalists that’ll receive up to $3 million each.

The four Houston companies that have been named semifinalists are:

  • Climate Robotics. The company’s mobile platform produces and applies biochar — organic waste material or biomass — to store CO2.
  • Mati Carbon. The companyremoves carbon dioxide and stores it in rocks to boost rice productivity in the U.S.
  • 1PointFive. The company, a subsidiary of Occidental Petroleum, is building facility that will eventually capture up to 500,000 metric tons of CO2 per year.
  • Vaulted Deep. The companyundertakes geologic storage of slurried organic waste for permanent removal of CO2.

Granholm says the DOE prize program and the Biden administration are giving the private sector the tools they need to make real contributions to our fight against the climate crisis and deliver real benefits to communities across the nation.”

Three of the companies selected — Vaulted Deep, Mati Carbon, and Climate Robotics — were also recently named finalists in Elon Musk's XPRIZE's four-year global competition is designed to combat climate change with innovative solutions.

3 Houston clean energy startups advance in Elon Musk-backed cleantech competition

finalists

Twenty promising climatetech companies were selected to advance to the final stage of a global competition backed by Elon Musk's foundation — and three of the finalists hail from Houston.

Vaulted Deep, Mati Carbon, and Climate Robotics secured finalists spots in XPRIZE's four-year global competition is designed to combat climate change with innovative solutions. XPRIZE Carbon Removal will offer $100 million to innovators who are creating solutions that removes carbon dioxide directly from the atmosphere or the oceans, and then sequester it sustainably.

"For the world to effectively address greenhouse gas emissions, carbon removal is an essential element of the path to Net Zero. There's no way to reverse humanity's impact on the climate without extracting carbon from our atmosphere and oceans," Anousheh Ansari, CEO of XPRIZE, says in a news release. "We need a range of bold, innovative CDR solutions to manage the vast quantities of CO2 released into our environment and impacting our planet.

"The teams that have been competing for this Prize are all part of building a set of robust and effective solutions and our 20 teams advancing to the final stage of XPRIZE Carbon Removal will have an opportunity to demonstrate their potential to have a significant impact on the climate," Ansari continues.

The finalists — categorized into four sections: air, rocks, oceans, and land — were selected based upon their performance in three key areas: operations, sustainability, and cost. The full list of 20 finalists is available online.

Around 20 Houston-area companies were initially identified by the challenge. Here's a look at the three that are advancing to the finals:

  • Mati, in the Rocks category, durably removes carbon from the atmosphere using basalt based enhanced rock weathering (ERW) in smallholder rice paddy farms. This process, which is being demonstrated in India, removes atmospheric CO2 while adding key nutrients in the soil helping to restore degraded soils to benefit smallholder farmers.
  • Climate Robotics, in the Land category, enables broad-scale agriculture adoption of biochar which builds soil health and removes excess carbon from the atmosphere. The company's mobile technology converts crop residues into durable biochar on the fly and in the field, making the economics work for farmers and our ecosystems.
  • Vaulted Deep, also in the Land category, delivers scalable, permanent, carbon removal by geologically sequestering carbon-filled organic wastes. Their patented slurry sequestration, which involves the geological injection of minimally processed wastes for permanent (10,000+ year) carbon removal.

"This cohort of exceptional teams represents a diversity of innovations and solutions across a range of CDR pathways, and shows the significant progress the industry is making in a short period of time," Nikki Batchelor, executive director of XPRIZE Carbon Removal, says in the release. "Over the past three years, this competition has helped accelerate the pace of technology development for a whole new industry of high-potential solutions aimed at reversing climate change."

Innovative Houston clean hydrogen company expands to Brazil

on the move

Houston biotech company Cemvita has expanded into Brazil. The company officially established a new subsidiary in the country under the same name.

According to an announcement made earlier this month, the expansion aims to capitalize on Brazil’s progressive regulatory framework, including Brazil’s Fuel of the Future Law, which was enacted in 2024. The company said the expansion also aims to coincide with the 2025 COP30, the UN’s climate change conference, which will be hosted in Brazil in November.

Cemvita utilizes synthetic biology to transform carbon emissions into valuable bio-based chemicals.

“For decades Brazil has pioneered the bioeconomy, and now the time has come to create the future of the circular bioeconomy,” Moji Karimi, CEO of Cemvita, said in a news release. “Our vision is to combine the innovation Cemvita is known for with Brazil’s expertise and resources to create an ecosystem where waste becomes opportunity and sustainability drives growth. By joining forces with Brazilian partners, Cemvita aims to build on Brazil’s storied history in the bioeconomy while laying the groundwork for a circular and sustainable future.”

The Fuel of the Future Law mandates an increase in the biodiesel content of diesel fuel, starting from 15 percent in March and increasing to 20 percent by 2030. It also requires the adoption of Sustainable Aviation Fuel (SAF) and for domestic flights to reduce greenhouse gas emissions by 1 percent starting in 2027, growing to 10 percent reduction by 2037.

Cemvita agreed to a 20-year contract that specified it would supply up to 50 million gallons of SAF annually to United Airlines in 2023.

"This is all made possible by our innovative technology, which transforms carbon waste into value,” Marcio Da Silva, VP of Innovation, said in a news release. “Unlike traditional methods, it requires neither a large land footprint nor clean freshwater, ensuring minimal environmental impact. At the same time, it produces high-value green chemicals—such as sustainable oils and biofuels—without competing with the critical resources needed for food production."

In 2024, Cemvita became capable of generating 500 barrels per day of sustainable oil from carbon waste at its first commercial plant. As a result, Cemvita quadrupled output at its Houston plant. The company had originally planned to reach this milestone in 2029.

Capitalism and climate: How financial shifts will shape our behavior

guest column

I never imagined I would see Los Angeles engulfed in flames in this way in my lifetime. As someone who has devoted years to studying climate science and advocating for climate technology solutions, I'm still caught off guard by the immediacy of these disasters. A part of me wants to believe the intensifying hurricanes, floods, and wildfires are merely an unfortunate string of bad luck. Whether through misplaced optimism or a subconscious shield of denial, I hadn't fully processed that these weren't just harbingers of a distant future, but our present reality. The recent fires have shattered that denial, bringing to mind the haunting prescience of the movie Don't Look Up. Perhaps we aren't as wise as we fancy ourselves to be.

The LA fires aren't an isolated incident. They're part of a terrifying pattern: the Canadian wildfires that darkened our skies, the devastating floods in Spain and Pakistan, and the increasingly powerful hurricanes in the Gulf. A stark new reality is emerging for climate-vulnerable cities, and whether we acknowledge the underlying crisis or not, climate change is making its presence felt – not just in death and destruction, but in our wallets.

The insurance industry, with its cold actuarial logic, is already responding. Even before the recent LA fires, major insurers like State Farm and Allstate had stopped writing new home policies in California, citing unmanageable wildfire risks. In the devastated Palisades area, 70% of homes had lost their insurance coverage before disaster struck. While some homeowners may have enrolled in California's limited FAIR plan, others likely went without coverage. Now, the FAIR plan faces $5.9 billion in potential claims, far exceeding its reinsurance backup – a shortfall that promises delayed payments and costlier coverage.

The insurance crisis is reverberating across the nation, and Houston sits squarely in its path. As a city all too familiar with the destructive power of extreme weather, we're experiencing our own reckoning. The Houston Chronicle recently reported that local homeowners are paying a $3,740 annually for insurance – nearly triple the national average and 60% higher than the Texas state average. Our region isn't just listed among the most expensive areas for home insurance; it's identified as one of the most vulnerable to climate hazards.

For Houston homeowners, Hurricane Harvey taught us a harsh lesson: flood zones are merely suggestions, not guarantees. The next major hurricane won't respect the city's floodplain designations. This reality poses a sobering question: Would you risk having your largest asset – your home – uninsured when flooding becomes increasingly likely in the next decade or two?

For most Americans, home equity represents one of the largest components of household wealth, a crucial stepping stone to financial security and generational advancement. Insurance isn't just about protecting physical property; it's about preserving the foundation of middle-class economic stability. When insurance becomes unavailable or unaffordable, it threatens the very basis of financial security for millions of families.

The insurance industry's retreat from vulnerable markets – as evidenced by Progressive and Foremost Insurance's withdrawal from writing new policies in Texas – is more than a business decision. It's a market signal. These companies are essentially pricing in the reality of climate change, whether we choose to call it that or not.

What we're witnessing is the market beginning to price us out of areas where we've either built unsustainably or perhaps should never have built at all. This isn't just about insurance rates; it's about the future viability of entire communities and regional economies. The invisible hand of the market is doing what political will has failed to do: forcing us to confront the true costs of our choices in a warming world.

Insurance companies aren't the only ones sounding the alarm. Lenders and investors are quietly rewriting the rules of capital access based on climate risk. Banks are adjusting mortgage terms and raising borrowing costs in vulnerable areas, while major investment firms are factoring carbon intensity into their lending decisions. Companies with higher environmental risks have faced higher loan spreads and borrowing costs – a trend that's accelerating as climate impacts intensify. This financial reckoning is creating a new economic geography, where access to capital increasingly depends on climate resilience.

The insurance crisis is the canary in the coal mine, warning us of the systemic risks ahead. As actuaries and risk managers factor climate risks into their models, we're seeing the beginning of a profound economic shift that will ripple far beyond housing, affecting businesses, agriculture, and entire regional economies. The question isn't whether we'll adapt to this new reality, but how much it will cost us – in both financial and human terms – before we finally act.
