A Houston sustainability startup has secured a major win on a global scale.

Revterra, which produces novel batteries made from recycled steel, has been awarded a million-dollar piloting opportunity by ADNOC following a global competition.

The ADNOC Decarbonization Technology Challenge, in collaboration with AWS, bp, Hub71, and the Net Zero Technology Centre, sought to find emerging climate tech innovations that are ready for scale.

The contest drew 650 applicants from across 50 countries, and applicants specialized in innovations in oil and gas emissions reduction, nature-based solutions, carbon capture utilization and storage, digital applications, new energies, oil and gas emissions reduction and advanced materials for decarbonization.

At the event in Dubai, Revterra was selected from among 10 finalists receiving up to $1 million piloting opportunities. In addition to the $1 million, they will gain access to facilities and expertise at the ADNOC Research and Innovation Center in Abu Dhabi.

“We are thrilled to win this opportunity,” Patrick Flam, CFO of Revterra, says in a news release. “At Revterra, we have developed an environmentally friendly battery that doesn’t rely on metals like lithium, nickel, or cobalt. Instead, our 2MW batteries are built using recycled steel and rely on rotational energy storage technology to achieve maximum power with a minimal environmental footprint. I am excited to work with our new partners at ADNOC to further develop our solution and deploy it across ADNOC’s operations.”

ADNOC is accelerating the decarbonization of its operations and looks to reduce its carbon intensity by 25 percent by 2030.

“ADNOC is leveraging partnerships and innovative climate technologies to accelerate our decarbonization goals and responsibly enable the energy transition,” Musabbeh Al Kaabi, ADNOC executive director for Low Carbon Solutions and International Growth, adds in the release. “The ADNOC Decarbonization Technology Challenge supports this objective, and we congratulate Revterra for emerging victorious amongst very competitive submissions from around the world.

"We look forward to working with Revterra to unlock cutting-edge solutions that will enhance efficiencies and continue decarbonizing our operations,” he continues.

Clean tech co. with U.S. HQ selected for UAE carbon capture project

big win

Abu Dhabi National Oil Co. (ADNOC), the state-owned oil company of the United Arab Emirates, has chosen technology from United Kingdom-based company Carbon Clean for a carbon capture project in Abu Dhabi. Carbon Clean’s U.S. headquarters is in Houston.

Carbon Clean’s modular CycloneCC technology will be used for a carbon capture project at a Fertiglobe nitrogen fertilizer plant. Fertiglobe is a joint venture between ADNOC and OCI Global, a Netherlands-based chemical company.

“This project is hugely significant given it’s the first industrial deployment of our award-winning CycloneCC technology anywhere in the world,” says Aniruddha Sharma, chairman and CEO of Carbon Clean. “We are moving a step closer to achieving full commercialization of this modular solution, which will play a vital role in decarbonizing heavy industries and achieving net-zero targets.”

Carbon Clean develops carbon capture technology for customers such as cement producers, steelmakers, refineries, and waste-to-energy plants. The company bills its offering as the “world’s smallest industrial carbon capture technology.”

CycloneCC can reduce the cost of carbon capture by as much as 50 percent with a footprint that’s 50 percent smaller than traditional carbon capture units, according to Carbon Clean. The startup’s unit arrives ready to install and can be up and running in eight weeks.

The company established its Houston outpost earlier this year.

In 2022, Houston-based Chevron New Energies led the company’s $150 million series C round. Other contributors to the round were CEMEX Ventures, Marubeni, WAVE Equity Partners, AXA IM Alts, Samsung Ventures, Saudi Aramco Energy Ventures, and TC Energy. To date, Carbon Clean has raised $195 million.

Houston startup raises $12M to commercialize quantum energy chip technology

seed funding

Houston-based Casimir has emerged from stealth with a $12 million seed round to commercialize its quantum energy chip.

The round was led by Austin-based Scout Ventures. Lavrock Ventures, Cottonwood Technology, Capital Factory, American Deep Tech, and Tim Draper of Draper Associates also participated in the round. The oversubscribed round exceeded the company’s original $8 million target, according to a news release.

Casimir’s semiconductor chips can generate power from quantum vacuum fields without the need for batteries or charging. The company plans to commercialize its first-generation MicroSparc chip by 2028.

The MicroSparc chip measures 5 millimeters by 5 millimeters and is designed to produce 1.5 volts at 25 microamps, comparable to a small rechargeable battery, without degradation and no replacement cycle.

“Casimir represents exactly the kind of breakthrough dual-use technology Scout Ventures was built to back,” Brad Harrison, founder and managing partner at Scout Ventures, said in the release. “This is based on 100 years of science and we’re finally approaching a commercial product … We’re proud to lead this round and support Casimir’s journey from applied science to deployed technology.”

Casimir says it aims to scale its technology across the ”full power spectrum,” including large-scale energy systems that can power homes, commercial infrastructures and electric vehicles.

Casimir's scientific work has been supported by DARPA-funded nanofabrication research and its technology was incubated at the Limitless Space Institute (LSI). LSI is a nonprofit that works to innovate interstellar travel and was founded by Kam Ghaffarian. Technology investor and serial entrepreneur Ghaffarian has been behind companies like X-energy, Intuitive Machines, Axiom Space and Quantum Space.

Harold “Sonny” White, founder and CEO of Casimir, believes the technology can power devices for years without replacements.

“Millions of devices will operate for years without a battery ever needing to be replaced or recharged because we have engineered a customized Casimir cavity into hardware capable of producing persistent electrical power,” White added in the release. “I spent nearly two decades at NASA studying how we power humanity’s future. That work led me to the Casimir effect and the quantum vacuum, where new tools have allowed us to build on a century of scientific knowledge and bring abundant power to the world.”

Electric truck charging network expands to Houston-Dallas freight corridor

electric trucking

Greenlane Infrastructure, an electric public charging station developer and operator, is expanding outside of its home state of California and into Texas.

The Santa Monica-based company plans to launch its high-power charging sites along the Dallas–Houston I-45 corridor, which is one of the highest-volume commercial trucking routes in the country, according to a news release from Greenlane.

The sites will feature 6-8 pull-through lanes with chargers supporting combined charging system (CCS) and megawatt charging system (MCS) connectors that allow electric truck drivers to recharge their vehicles during standard rest periods. They will also offer tractor parking and charging, as well as operations that will allow for overnight stops.

Drivers can reserve chargers in advance, monitor charging activity in real time, and manage billing from the Greenlane Edge platform.

“Our customers are making commitments to electrify their fleets, and they need a charging network that can grow alongside them,” Patrick Macdonald-King, CEO of Greenlane, said in the release. “This is the first leg of the Texas triangle, one of the more important freight arteries in the country, so bringing high-power charging there is the next logical step in building a network that serves how freight moves across America.”

Greenlane is also expanding across the West Coast, with five locations under development in California and Nevada. It opened its flagship Greenlane Center in Colton, California, in April 2025. The company plans to open locations in Blythe, California, and Port of Long Beach this year.

Greelane was founded in 2023 as a joint venture between Daimler Truck North America, NextEra Energy Resources and BlackRock. It has secured partnerships with electric long-haul truck developer Windrose Technology, Velocity Truck Centers and Volvo Trucks North America.
