DivInc, a Texas-based accelerator focused on uplifting people of color and women founders, recently concluded their inaugural clean energy cohort, catapulting several early-stage companies to major milestones.

The 12-week intensive Clean Energy Tech accelerator program sponsored by Chevron and Microsoft instructed seven clean energy startup founders at the Ion, through a variety of workshops, mentor sessions, and deep dives with VC professionals. DivInc also gave each startup a non-dilutive $10,000 grant to use during the course of the program.

Cherise Luter, marketing director at DivInc, said the Austin-based development program decided to expand from its previous accelerators — Women in Tech and Sports Tech — into clean energy because it is a newer industry with ample potential.

“Clean energy is an emerging space where founders like ours, women and POC founders, can really get in on the ground floor in a great way so that they are building as well as benefiting from this new space,” Luter tells EnergyCapital.

Luter said corporate partners Chevron and Microsoft were similarly on board with prioritizing diversity in the clean energy sector and together they agreed Houston would be the best place to headquarter the accelerator for its expansive resources, particularly VCs.

“Houston, as the energy capital, the resources, connections, and network are here, and we have found that those are the things that are most important for our founders to be able to really take their companies to the next level,” Luter explains.

The participating startups’ focuses ranged from innovations in solar power to electric vehicle charging stations, but these corporations were all united in aiding the clean energy transition.

“It’s so interesting with this particular cohort, how they are really merging the human part of clean energy – how it’s contributing to a better life for people–with a better situation for our environment and our climate,” Luter says.

The inaugural cohort included one to two entrepreneurs from the following companies:

  • BlackCurrant Inc., based in Chicago, is transforming the hydrogen industry by simplifying OTC transactions and offering a comprehensive platform for businesses to seamlessly obtain equipment, fuel, and services essential for hydrogen adoption.
  • Owanga Solar, founded by two Emory University law students in Georgia, delivers sustainable and affordable solar energy solutions to households and businesses in the Democratic Republic of Congo.
  • Maryland-based Pirl Technology Inc. is building next generation electric vehicle charging stations.
  • Houston-based Quantum New Energy has a software platform, called EnerWisely, that helps those who own assets that reduce carbon emissions, like solar panels, generate high quality, verifiable carbon credits that don’t green wash.
  • SOL roofs, founded by Austinite Daniel Duerto, is creating the next generation of solar roofs through innovating existing technologies.
  • WIP International Services LLC, a Houston-based company, is addressing drinking water scarcity with its atmospheric water generators, which produce fresh drinking water from the humidity in the air.

Tracy Jackson, CEO of WIP International Services LLC, announced on the accelerator’s demo day her Houston-based company that produces atmospheric water generators, which transform humid air into clean drinking water, contracted with several schools in El Salvador for a pilot program to send 40 of their smaller models.

“We’re going to continue on our path and we’re looking forward to signing more international contracts and look forward to having any local opportunities that we can develop as well,” Jackson says.

Since the program ended, Luter shared WIP has also secured a “major international contract in Mexico.”

Luter also shared that accelerator participant Quantum New Energy, a climatech Houston-based company, has pre-launched expansion of EnerWisely, their software that tracks carbon credits, for commercial facilities.

Luter says DivInc plans to eventually host another cohort of their clean energy accelerator and they are continuing to accept applications from founders on a rolling basis.

More than 100 startups joined Greentown this year, according to an end-of-year reflection shared by Greentown CEO Georgina Campbell Flatter.

Flatter joined Greentown in the top leadership role in February 2025. She succeeded former CEO and president Kevin Knobloch, who stepped down in July 2024.

"I moved back to the United States in March 2025 after six years overseas—2,000 miles, three children, and one very patient husband later. Over these months, I’ve had the chance to hear from the entrepreneurs, industry leaders, investors, and partners who make this community thrive. What I’ve experienced has left me brimming with urgent optimism for the future we’re building together," she said in the release.

According to Flatter, Greentown alumni raised more than $2 billion this year and created more than 3,000 jobs.

"Greentown startups and ecosystem leaders—from Boston, Houston, and beyond—are showing that we can move further and faster together. That we don’t have to choose between more energy or lower emissions, or between increasing sustainability and boosting profit. I call this the power of 'and,'" Flatter added. "We’re working for energy and climate, innovation and scale, legacy industry and startups, prosperity for people and planet. The 'and' is where possibility expands."

NRG makes latest partnership to grow virtual power plant

VPP partners

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
