Two companies have teamed up on decarbonization efforts and made their relationship official at Houston's Offshore Technology Conference last week.

ABS and Seatrium signed a three-year Technology Collaboration Agreement at OTC, which expands on "their long running partnership on cutting-edge marine and technology projects," per a news release.

The agreement is entitled “Accelerating Decarbonization and Energy Transition,” and covers collaboration on technologies that fall under four broad themes: decarbonization, electrification, new energies and digital transformation.

“Together, ABS and Seatrium have a remarkable history of pioneering the technological frontiers in the marine and offshore industries,” says Christopher J. Wiernicki, ABS chairman and CEO, says in a release. "Our shared vision for the future, combined with our twin cultures of innovation and collaboration mean we are well placed to safely deliver the rapid technological advance our industry needs if we are to meet emissions targets and capitalize on the opportunities offered by decarbonization and digitalization."

The agreement is intended to support commercialization across the four identified themes.

“Seatrium is making significant strides in our visionary approach to engineering a sustainable, low-carbon energy future. This progress is achievable through pivotal industry collaborations with organizations like ABS," Chris Ong, CEO of Seatrium, adds. "We are more than just partners; we are natural allies united by a shared mission and driven by a powerful vision for a sustainable future.

"ABS and Seatrium have achieved great successes through our previous collaborations, and we are committed to harnessing our distinct strengths and capabilities to push the boundaries and transform the way we approach decarbonization, energy transition, and digital transformation,” he continues.

ABS, a 150-year-old marine and offshore energy innovation company, is headquartered in the Houston area. Seatrium, which is headquartered in Singapore, was recognized by ABS as the first shipyard group to deploy smart technologies in its operations.

The accolades keep rolling in for Houston-based Fervo Energy, a producer of geothermal power.

Fervo lands at No. 6 on Time magazine and Statista’s new list of America’s Top GreenTech Companies of 2025. The ranking recognizes sustainability-focused companies based on factors such as impact, financial strength, and innovation.

Time notes that Fervo broke ground in 2023 in Utah on what the company claims will be the world’s largest geothermal plant. The plant is scheduled to start supplying carbon-free electricity to the grid next year and to reach its 400-megawatt capacity in three years.

“Technologies like this only make a difference if we deploy them at large-scale in a way that can reduce carbon emissions and increase the reliability of the grid,” Fervo CEO Tim Latimer told Time in 2023.

The startup was named North American Company of the Year by research and consulting firm Cleantech Group for 2025. Fervo topped the Global Cleantech 100, Cleantech Group’s annual list of the world’s most innovative and promising cleantech companies.

Last year, Fervo also made Time’s list of the 200 Best Inventions of 2024. Fervo was recognized in the green energy category for its FervoFlex geothermal power system.

Founded in 2017, Fervo is now a unicorn, meaning its valuation as a private company exceeds $1 billion. The startup’s valuation is estimated at $1.4 billion. According to PitchBook data, the company raised $634 million in the fourth quarter of 2024.

In all, eight Houston-area companies appear among the top 250 greentech companies ranked by Time and Statista. Other than Fervo, they are:

  • No. 43 Lancium Technologies, an energy storage and distribution company
  • No. 50 Solugen, a producer of sustainable chemicals.
  • No. 56 Quaise Energy, which specializes in terawatt-scale geothermal power.
  • No. 129 Plus Power, a developer, owner and operator of battery storage projects.
  • No. 218 Dream Harvest, which promotes sustainable vertical farming.
  • No. 225 Cemvita, which uses synthetic biology to convert carbon emissions into bio-based chemicals.
  • No. 226 Syzygy Plasmonics, which decarbonizes chemical production.
Vermont-based BETA Technologies claimed the No. 1 spot. The company manufactures electric aircraft.
