A Houston energy tech startup has raised a $21.5 million series a round of funding to support the advancement of its automated technology that converts field wastes into stable carbon.

Applied Carbon, previously known as Climate Robotics, announced that its fresh round of funding was led by TO VC, with participation from Congruent Ventures, Grantham Foundation, Microsoft Climate Innovation Fund, S2G Ventures, Overture.vc, Wireframe Ventures, Autodesk Foundation, Anglo American, Susquehanna Foundation, US Endowment for Forestry and Communities, TELUS Pollinator Fund for Good, and Elemental Excelerator.

The series A funding will support the deployment of its biochar machines across Texas, Oklahoma, Arkansas, and Louisiana.

"Multiple independent studies indicate that converting crop waste into biochar has the potential to remove gigatons of CO2 from the atmosphere each year, while creating trillions of dollars in value for the world's farmers," Jason Aramburu, co-founder and CEO of Applied Carbon, says in a news release. "However, there is no commercially available technology to convert these wastes at low cost.

"Applied Carbon's patented in-field biochar production system is the first solution that can convert crop waste into biochar at a scale and a cost that makes sense for broad acre farming," he continues.

Applied Carbon rebranded in June shortly after being named a top 20 finalist in XPRIZE's four-year, $100 million global Carbon Removal Competition. The company also was named a semi-finalist and awarded $50,000 from the Department of Energy's Carbon Dioxide Removal Purchase Pilot Prize program in May.

"Up to one-third of excess CO2 that has accumulated in the atmosphere since the start of human civilization has come from humans disturbing soil through agriculture," Joshua Phitoussi, co-founder and managing partner at TO VC, adds. "To reach our net-zero objectives, we need to put that carbon back where it belongs.

"Biochar is unique in its potential to do so at a permanence and price point that are conducive to mass-scale adoption of carbon dioxide removal solutions, while also leaving farmers and consumers better off thanks to better soil health and nutrition," he continues. "Thanks to its technology and business model, Applied Carbon is the only company that turns that potential into reality."

The company's robotic technology works in field, picking up agricultural crop residue following harvesting and converts it into biochar in a single pass. The benefits included increasing soil health, improving agronomic productivity, and reducing lime and fertilizer requirements, while also providing a carbon removal and storage solution.

"We've been looking at the biochar sector for over a decade and Applied Carbon's in-field proposition is incredibly compelling," adds Joshua Posamentier, co-founder and managing partner of Congruent Ventures. "The two most exciting things about this approach are that it profitably swings the agricultural sector from carbon positive to carbon negative and that it can get to world-scale impact, on a meaningful timeline, while saving farmers money."

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.

seeing less co2

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 company removes 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 company undertakes 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."

Houston cleantech startup secures $134M to develop ‘superhot’ geothermal plant

deep round

Houston-based Quaise Energy, a producer of utility-scale geothermal power, raised $134 million in a Series B round to advance its “superhot” geothermal power plant.

Climate-focused San Francisco-based investment firm Prelude Ventures led the round, with participation from JERA Co., Japan’s largest power generation company, and Idemitsu Kosan, one of Japan’s largest energy companies. Nearly all existing investors, including cleantech-focused investment firm Safar Partners, participated in the round.

“We have backed Quaise since the beginning because we believed accessing superhot rock would unlock geothermal energy at a scale the world has never seen,” Mark Cupta, managing director at Prelude Ventures, said in a press release.

The startup expects more equity and debt deals to close “imminently.” Quaise has raised $230 million since its founding in 2018.

Quaise says some of the fresh funding will go toward building the world’s first commercial-scale “superhot” geothermal power plant —Project Obsidian in central Oregon. In addition, Quaise is earmarking money for continued development and commercialization of its millimeter-wave drilling system toward depths exceeding 5 kilometers (about 16,400 feet).

Quaise uses a millimeter-wave drilling system developed at the Massachusetts Institute of Technology to remove rock at depths and temperatures that aren’t economically feasible with conventional drilling. With this technology, Quaise can reach rock at temperatures of around 570 degrees to 930 degrees in most places worldwide, enabling construction of geothermal systems that rival fossil fuels and nuclear energy in power density and that rival renewables in cost.

“Our ambition is to power civilization with Earth's most compelling energy source. This round takes us from field-proven technology to first commercial revenues,” Carlos Araque, co-founder, president and CEO of Quaise, added in the release.

Quaise has demonstrated the capability of its millimeter-wave drilling system at its Central Texas test site, drilling more than about 330 feet through granite in 2025—the first time the technology penetrated basement rock at full scale in the field. The company is approaching a depth of about 3,300 feet at the same site.

Construction of Project Obsidian is underway at Oregon’s Deschutes National Forest. The project, which has the potential to generate gigawatt-scale power, is slated to deliver electricity to the Pacific Northwest grid by 2030.

Shell expands lower-carbon energy solutions while cutting emissions

The View from HETI

Shell’s approach to sustainable development reflects an integrated value chain perspective—reducing emissions from oil and gas production, transforming downstream businesses to offer more low-carbon solutions, and building new energy businesses at scale.

UH report projects $1T in new midstream infrastructure needed to power AI era

midstream report

A new study from the University of Houston estimates that the U.S. will need more than $1 trillion in new midstream energy infrastructure investment by 2052 to meet the rising energy demands from data centers in the age of artificial intelligence.

According to the report, this would average $40 billion to $48 billion per year across investments in natural gas, oil, natural gas liquids, hydrogen and CO2 infrastructure.

UH, in collaboration with the INGAA Foundation and Wood and ESMIA Consultants, released the 2025 North American Midstream Infrastructure Report, which details the needs, pipelines and associated infrastructure necessary to meet global market needs and increased energy demands. UH led the consortium that conducted the analysis. Paul Doucette, hydrogen program officer at UH, served as the principal investigator of the report.

According to the U.S. Department of Energy, data center energy consumption could reach 800 terawatt-hours annually by 2050, a roughly 167 percent increase from 300 terawatt-hours in 2025. Meanwhile, electricity generation from all energy sources is projected to reach 5,858 terawatt-hours in 2052, a 27 percent increase over current levels.

The report proposes two routes to meeting this level of demand.

The first scenario is a reference case based on current federal, state and provincial policies as of April 1, 2025. The second option presents a low-carbon scenario. The report concludes that natural gas would need to remain a “foundational component of the region’s energy system” in both scenarios.

“Meeting energy demand is a critical challenge right now, and this report quantifies the necessary midstream infrastructure and corresponding development dollars needed to meet that demand,” Hebe Shaw, executive director of the INGAA Foundation, said in a news release. “Meeting the energy needs of North America will require sustained investment and development, which must begin now to ensure a safe, reliable and affordable energy system.”

The report also identified several key midstream infrastructure requirements, including:

  • 103,000 miles of new natural gas gathering pipelines
  • 37,000 miles of additional natural gas transmission pipelines, which includes approximately 33,800 miles in the United States
  • 24 million jobs over 25 years

The report adds that hydrogen, carbon capture, utilization, and storage (CCUS), and other decarbonization strategies can help meet infrastructure needs.
