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.

Houston-based GoodPeak has nailed down $22 million in construction debt financing to help build its first two 10-megawatt battery energy storage projects, both of which are expected to come online in the Houston area at the end of 2025.

GoodPeak secured the debt financing from financial services company Pathward and renewable energy lender BridgePeak Energy Capital.

GoodPeak says an undisclosed amount of funding from private equity firm Current Equity Partners and other investors will further spur growth. That growth starts with the construction of the two Houston-area battery energy storage projects, which will serve the Electric Reliability Council of Texas (ERCOT), whose power grid serves most of the state.

Aside from Current Equity Partners, investors in GoodPeak include executives, family offices, and energy industry advisers.

“GoodPeak plans to expand and diversify its development pipeline to include larger projects, integrated power generation, and data center development opportunities,” the company says in a news release.

GoodPeak’s initial development pipeline includes 10 ERCOT projects in the Houston and Dallas-Fort Worth areas, and 14 projects in Northern California. The combined capacity of the projects will be 1 gigawatt.

Founded in 2022 by Trent Kososki and Hayden Stanley, GoodPeak develops, owns, and operates utility-scale battery storage and solar power assets for “high-value, capacity-constrained locations.”

“Breaking ground on our first energy storage projects marks a major milestone for GoodPeak in helping to solve Texas’ grid challenges,” says Kososki, CEO of GoodPeak. “These projects will provide much-needed resilience to the grid, storing excess power during times of low demand and delivering it when it’s needed most — helping to stabilize energy prices, support renewable integration, and enhance overall reliability.”

In a 2024 LinkedIn post, Kososki wrote that he was “embarking upon a new adventure in establishing GoodPeak — a battery energy storage platform with a mission to aggressively pursue descent from the world’s mountain of carbon emissions.”
