Greentown Labs announced that it added five startups to its Houston community in Q1 of 2025.

The companies are among a group of 19 that joined the climatetech incubator, which is co-located in Houston and Boston, in the same time period. The companies that joined the Houston-based lab specialize in a number of "green" applications, from converting plastic waste into sustainable materials to developing energy-storage solutions.

The new Houston members include:

  • Concept Loop, a project of Pakistan-based Innova8e Inc., aims to repurpose post-industrial and post-consumer plastic waste into sustainable building materials.
  • GeoFuels, a Sugar Land-based company that produces hydrogen by using baseload geothermal power and methane pyrolysis.
  • PLASENE, a Houston-based company with an innovative platform that converts plastic waste into liquid fuel and low-carbon hydrogen through its proprietary catalysts and modular, scalable, pre-engineered units platform. The company was named to Greentown's ACCEL Year 3 cohort earlier this year.
  • RepAir Carbon, an Israeli company with a fully electric, zero-heat carbon-removal technology that consumes minimal energy, operates without liquids or solvents, and produces no hazardous materials or waste.
  • RotorVault from Pasadena, California, is commercializing energy-storage and load-following solutions that are containerized, modular, and field-deployable systems built on flywheel technology.

Fourteen other companies will join Greentown Boston's incubator. See the full list here.

PLASENE and five other new members—Thola, Respire Energy, Andros Innovations, FAST Metals and Tato Labs—join Greentown Labs through its most recent Advancing Climatetech and Clean Energy Leaders Program, or ACCEL, cohort. ACCEL, which works to advance BIPOC-led startups in the climatetech space, announced its third cohort last month.

In recent months, Houston-based energy corporation Baker Hughes has launched multiple partnerships to expand geothermal energy extraction across the United States. The latest, a deal with Oklahoma-based Helmerich & Payne Inc. (H&P), was announced Wednesday.

As part of the deal, H&P will provide a geothermal-capable land drilling rig, while Baker Hughes will contribute technology and expertise. The rig is expected to be deployed later this year, according to a news release.

“Geothermal energy plays a critical role in meeting growing power demand by providing clean, reliable baseload generation,” Amerino Gatti, executive vice president of oilfield services & equipment for Baker Hughes, said in the release. “This collaboration reflects a deliberate step to move its development in the U.S. from concept to reality. By working together, Baker Hughes and Helmerich & Payne are helping customers advance these critical energy projects with greater confidence and deliver reliable, sustainable power.”

Investment in the geothermal energy sector is currently exploding in the U.S., having grown by at least 1,000 percent just in the last seven years, according to a recent report by Rocky Mountain Institute.

On one hand, only about 1 percent of the American energy grid currently uses geothermal, but on the other, the U.S. holds roughly 25 percent of the world’s geothermal capacity. Harnessing that power becomes even more attractive as conflicts in Russia and Iran continue to hamstring energy markets from those countries and revitalize interest in renewable energy.

Baker Hughes has been at the forefront of the geothermal boom. This new deal with H&P combines H&P’s drilling platform technology with Baker Hughes’s subsurface and energy extraction support technologies.

“This agreement underscores Helmerich & Payne’s commitment to supporting emerging energy opportunities through our drilling technologies and operational expertise,” H&P President and CEO Trey Adams added in the release. “We are pleased to collaborate with Baker Hughes to support the advancement of geothermal development in the United States.”

The deal with H&P is just one of several recent ones Baker Hughes has closed. In March, they announced support for XGS’s geothermal extraction projects in New Mexico, which are being used to meet the increasing demands of data centers in the state. Last May, Fervo Energy selected Baker Hughes to supply equipment for its flagship geothermal project in Utah.
