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.

Texas City ammonia plant acquired by Yara in $1.3 billion deal

Ammonia Acquisition

Yara North America, a subsidiary of Norwegian fertilizer and ammonia producer Yara International, has agreed to buy an ammonia production plant in Texas City for $1.3 billion.

The seller is GCA Holdings, an affiliate of Texas City-based chemical manufacturer Gulf Coast Ammonia, which is owned by private equity firms Lotus Infrastructure Partners and MB Energy.

The Texas City plant, with an eventual annual capacity of 1.3 million metric tons, is expected to start full production by the end of this year. Yara says the ammonia produced by the plant will serve its own fertilizer production system and its key customers.

During a recent call with analysts and investors, Magnus Ankarstrand, executive vice president and CFO of Yara International, said the plant holds the potential to become one of the company’s most profitable plants. The $1.3 billion purchase price, he added, “is a very attractive entry ticket to ammonia production in the U.S. at a very attractive cost.”

The Texas City plant will add to Yara’s holdings in the Lone Star State, as Yara is the majority owner of an ammonia, hydrogen and nitrogen production plant in Freeport.

Construction of the ammonia plant began in 2020, but technical and infrastructure issues delayed the project. On its website, Gulf Coast Ammonia says the plant represented a $600 million investment.

“Gulf Coast Ammonia is a world-class asset that required disciplined execution across development, financing, construction, and commercial structuring,” Philipp Pletka, managing director of Lotus Infrastructure Partners, says in a news release.

Trexlertown, Pennsylvania-based Air Products, which owns and operates the country’s largest hydrogen pipeline network, will continue to supply hydrogen and nitrogen for the plant under a long-term deal with Yara, according to the release.

However, the news comes two days after Yara International announced that it would no longer be purchasing ammonia assets in the Louisiana Clean Energy Complex (LCEC) from Air Products. In a separate release, Yara said it planned to reallocate funds toward "alternative mature U.S. ammonia investment opportunities with more competitive returns."

Houston hypersonic engine company lands $91M to accelerate production

Clean Speed

Houston-based Venus Aerospace has closed a $91 million Series B round and plans to scale the production of its hypersonic engine.

The round was led by Houston-based Mercury Fund with participation from Lockheed Martin Ventures, MESH, PEAK6, Draper Associates, Starboard Star Venture Capital, Green Sands Equity and other investors, according to a news release.

The investment comes about a year after Venus completed the first U.S. flight test of its high-thrust rotating detonation rocket engine (RDRE). The engine is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus Aerospace says the latest round of funding will allow it to move the RDRE from demonstration to deployment and meet customer requirements for the near-term defense and space industries. The company says that the reusable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types.

“This financing marks an important step in moving Venus from breakthrough demonstration to scaled capability,” Sassie Duggleby, co-founder and CEO, said in the news release. “Our customers need propulsion systems that go farther, can be produced reliably and are built on supply chains they can trust. We are advancing that capability with American engineering and manufacturing talent to strengthen U.S. defense, expand space access and support the future of high-speed flight.”

Venus Aerospace raised a $20 million Series A in 2022, led by Wyoming-based Prime Movers Lab. At the time, the company said it would put the funding toward three main technologies: a next-generation rocket engine, aircraft shape and leading-edge cooling system.

The company also picked up an investment from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, in November 2025—in addition to funding from other investors over the years.

“Since our initial investment, Venus has progressed very quickly in its technology development," Chris Moran, vice president and general manager of Lockheed Martin Ventures, added in the release. "Our reinvestment in Venus recognizes Venus’ accomplishments to date and focus on speed to manufacture, cost management and reduction of supply chain constraints. Venus is working effectively to position its propulsion system for the production scale required by defense programs.”

"Venus is exactly the kind of company Houston capital should be backing," Blair Garrou, co-founder and managing partner at Mercury Fund, added in the release. "It combines multiple frontier technologies, domestic manufacturing and clear commercial and national security relevance. We believe this team is positioned to lead an important new chapter in defense and space, and we are proud to support a company building breakthrough technology here in Texas."

Venus Aerospace and Houston clean tech startup Vaulted Deep were also named to the World Economic Forum's Technology Pioneers community earlier this summer.
