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.

Solar tracking and manufacturing company PV Hardware USA is increasing its production capacity and expanding its Houston facility in an effort to meet growing demands.

The move marks the company's third expansion in the Houston area in three years. PV Hardware reports a 400 percent surge in national market growth over the past three years, as solar-based projects have been pivotal in energy resilience efforts.

PV Hardware plans to increase the capacity at its Houston facility by 42 percent, according to a news release. With the additional capacity, PV Hardware expects a 35 percent increase in production of pre-assembled parts. The company has not announced whether any additional employees will be hired or the costs of expansion.

In September, the company completed its new dedicated pre-assembly facility, which will help migrate difficult assembly into an easier manufacturing setting. The new pre-assembly area will also assist with streamlined field installation, enhanced schedule predictability and reduction of manual labor.

Citybiz reports that the expansion totals approximately 34,200 square feet.

PV Hardware USA aims to make solar installation more efficient. For large-scale solar projects, PV Hardware USA’s pre-assembly process helps to relieve assembly work done by installation teams. According to PV Hardware USA, it reduces the number of on-site components by 70 percent.

“Traditionally, manufacturers pushed the assembly burden onto the jobsite,” Rodolfo Bitar, vice president of business development for PVH USA, told Renewable Energy Magazine. “We ask a different question: what work can be done more efficiently before the equipment ever leaves the factory? By managing the assembly of 188 loose parts per row in our controlled manufacturing environment, we remove field complexity and make installation highly predictable.”

PV Hardware USA produces single-axis solar trackers made in Texas and has supplied over 52 gigawatts of solar trackers worldwide.

“The expanded presence in Texas underscores a long-term commitment: bringing world-class solar expertise to local American manufacturing, supporting communities, and serving as a reliable partner through the clean energy transition,” the company said in the release.

In July of 2025, the company opened its 95,000-square-foot facility, which was the second Houston location following its initial $30 million U.S. manufacturing facility, which, at 50,000 square feet, is one of America's largest solar tracker manufacturing facilities.
