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.

Carbon Clean develops carbon capture technology for customers such as cement producers, steelmakers, refineries, and waste-to-energy plants.

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 AI energy forecasting company lands investment from Samsung Ventures

funding for forecasts

Amperon, a Houston-based AI-powered forecasting solutions company, has received an investment for an undisclosed amount from Samsung Ventures, the corporate venture arm of Samsung Group.

According to Amperon, the funding will be put toward the company's global growth and next-generation product development. Samsung Ventures invests in emerging businesses developing technologies for the AI, advanced devices and energy-related sectors.

“Samsung Ventures’ investment is a strong validation of our mission to transform the way energy is forecasted and traded,” Sean Kelly, CEO and co-founder of Amperon, said in a news release. “Samsung’s global footprint and leadership in semiconductors, data infrastructure, and AI acceleration make them a natural fit as we expand Amperon’s reach into energy-intensive sectors like data centers. Their track record of scaling next-generation technologies aligns perfectly with our vision to build a more intelligent, resilient, and data-driven energy system.”

Amperon was founded in 2018. Its AI models combine real-time weather, consumption and market data for energy retailers, utilities and independent power producers.

Last year, the company launched its weather-informed grid demand Mid-Term Forecast (MTF), which provides users with data on electricity demand up to seven months in advance. It also secured strategic investments from Acario, the corporate venture capital and innovation division of Tokyo Gas, as well as National Grid Partners, the venture investment and innovation arm of National Grid (NYSE: NGG).

After expanding into Europe in 2024, the company has continued to see international growth, and currently operates in the U.S., Canada, Mexico, Australia, Europe and the Middle East.

“Amperon has demonstrated strong technical capabilities and global traction in a rapidly evolving energy landscape,” a spokesperson for Samsung Ventures added in the release. “Their ability to forecast and model real-time energy data at global scale positions them as a key enabler of smarter energy systems and climate resilience. We are pleased to invest in a company developing technologies that support a more sustainable and digitized world.”

Solar surpasses coal to become ERCOT’s third-largest power source in 2025

by the numbers

Solar barely eclipsed coal to become the third biggest source of energy generated for the Electric Reliability Council of Texas (ERCOT) in 2025, according to new data.

In 2024, solar represented 10 percent of energy supplied to the ERCOT electric grid. Last year, that number climbed to 14 percent. During the same period, coal’s share remained at 13 percent.

From the largest to smallest share, here’s the breakdown of other ERCOT energy sources in 2025 compared with 2024:

  • Combined-cycle gas: 33 percent, down from 35 percent in 2024
  • Wind: 23 percent, down from 24 percent in 2024
  • Natural gas: 8 percent, down from 9 percent in 2024
  • Nuclear: 8 percent, unchanged from 2024
  • Other sources: 1 percent, unchanged from 2024

Combined, solar and wind accounted for 37 percent of ERCOT energy sources.

Looking ahead, solar promises to reign as the star of the ERCOT show:

  • An ERCOT report released in December 2024 said solar is on track to continue outpacing other energy sources in terms of growth of installed generating capacity, followed by battery energy storage.
  • In December, ERCOT reported that more than 11,100 megawatts of new generating capacity had been added to its grid since the previous winter. One megawatt of electricity serves about 250 homes in peak-demand periods. Battery energy storage made up 47 percent of the new capacity, with solar in second place at 40 percent.

The mix of ERCOT’s energy is critical to Texas’ growing need for electricity, as ERCOT manages about 90 percent of the electric load for the state, including the Houston metro area. Data centers, AI and population growth are driving heightened demand for electricity.

In the first nine months of 2025, Texas added a nation-leading 7.4 gigawatts of solar capacity, according to a report from data and analytics firm Wood Mackenzie and the Solar Energy Industries Association.

“Remarkable growth in Texas, Indiana, Utah and other states ... shows just how decisively the market is moving toward solar,” says Abigail Ross Hopper, president and CEO of the solar association.
