Armed with a fresh $3 million round of seed funding, Los Altos, California-based Universal Fuel Technologies is establishing a lab in Houston for production of sustainable aviation fuel samples.

TO VC led the round, with participation from Alchemist Accelerator, Claire Technologies, and World Star Aviation.

Unifuel’s Flexiforming technology consists of a series of chemical reactions that convert various sustainable materials — such as ethanol, methanol, and liquified petroleum gas — into high-quality SAF that’s similar in chemical composition to traditional jet fuel.

“Today’s SAF production is challenged by feedstock limitations and expense, which are problems Unifuel’s Flexiforming solves,” Joshua Phitoussi, managing partner at TO VC, says in a news release. “Unifuel has engineered a more efficient SAF production method that dramatically cuts costs while getting the most out of limited resources.”

One of the key benefits of Flexiforming is that it creates the molecules needed for jet engines and other aircraft equipment to run smoothly. The addition of Flexiforming’s SAF allows for a fully synthetic jet fuel that airlines would be able to use without blending with conventional jet fuel once ASTM International (formerly the American Society of Testing and Materials) approves 100% SAF.

“Sustainable aviation depends upon developing SAF that is not only cost-effective but able to work within the aviation industry as it stands today,” says Alexei Beltyukov, CEO of Universal Fuel Technologies. “With Flexiforming, we can give SAF producers the ability to make affordable, high-quality SAF that has the characteristics needed for aircraft performance and the flexibility to scale at their own rate.”

Houston agriculture robotics co. raises $21.5M series A to grow climatetech solution

freshly funded

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."

NRG Energy forms joint venture to build power plants for ERCOT and AI-driven demand

teaming up

Houston-based power provider NRG Energy Inc. has formed a joint venture with two other companies to meet escalating demand for electricity to fuel the rise of data centers and the evolution of generative AI.

NRG’s partners in the joint venture are GE Vernova, a provider of renewable energy equipment and services, and TIC – The Industrial Co., a subsidiary of construction and engineering company Kiewit.

“The growing demand for electricity in part due to GenAI and the buildup of data centers means we need to form new, innovative partnerships to quickly increase America’s dispatchable generation,” Robert Gaudette, head of NRG Business and Wholesale Operations, said in a news release. “Working together, these three industry leaders are committed to executing with speed and excellence to meet our customers’ generation needs.”

Initially, the joint venture will work on four projects supplying 5 gigawatts of power from combined-cycle power plants, which uses a combination of natural gas and steam turbines that produce additional electricity from natural gas waste. Electricity from these projects will be produced for power grids operated by the Electric Reliability Council of Texas (ERCOT) and PJM Interconnection. The projects are scheduled to come online from 2029 through 2032.

The joint venture says the model it’s developing for these four projects is “replicable and scalable,” with the potential for expansion across the U.S.

The company is also developing a new 721-megawatt natural gas combined-cycle unit at its Cedar Bayou plant in Baytown, Texas. Read more here.

2 Houston startups join Greentown Labs' BIPOC-led accelerator program

seeing green

Greentown Labs and Browning the Green Space announced the newest cohort for its Advancing Climatetech and Clean Energy Leaders Program, or ACCEL, which works to advance BIPOC-led startups in the climatetech space.

Two Houston companies and one from Austin are among the eight startups to be named to the 2025 group.

“The startups selected for the third ACCEL cohort represent a phenomenal range of energy and climatetech innovations, which underscores our belief that everyone and many solutions must play a role in our community’s collective decarbonization efforts,” Georgina Campbell Flatter, Greentown’s new CEO, said in a release. “We’re proud to welcome these entrepreneurs to our community and eager to see all they’ll achieve throughout the program and beyond!”

Each of the early-stage startups within the cohort will receive $25,000 in non-dilutive grant funding and participate in the year-long program focused on product and technology development, market development, fundraising and management, and team development, according to Greentown. The curriculum is led by VentureWell, a nonprofit with expertise in venture development in climatetech.

The Houston companies include:

Carbonext, founded by Olanrewaju Tanimola. The company is leveraging its proprietary, off-the-shelf 3D-graphene technology to develop integrated solutions with carbon-coated silicon anodes to address challenges in the graphite ecosystem, as well as lithium-battery anodes.
PLASENE, founded by Sohel Shaikh, Alper Gulludag and Romolo Raciti. The company offers an innovative platform that converts plastic waste into liquid fuel and low-carbon hydrogen through its proprietary catalysts and modular, scalable, pre-engineered units

The remaining six companies are:
