Applications are officially open for a hardtech-focused incubation and fellowship program's second Houston cohort.

Activate's application is live from now through October 23, and all founders of early-stage, research-backed hardtech companies in Houston are encouraged to apply. The Berkley, California-based program launched in Houston last year and recently named its inaugural Houston cohort.

“The Activate Fellowship provides an opportunity for approximately 50 scientists and engineers annually to transform into entrepreneurial leaders, derisk their technologies, define first markets, build teams, and secure follow-on funding,” says Activate’s executive managing director, Aimee Rose, in a news release. “With an average 30 percent annual growth in applications since 2015, we know there is high demand for what we do, and we’re excited to see the talent and impactful ideas that come through the pipeline this year.

The program, led locally by Houston Managing Director Jeremy Pitts, has 249 current Activate fellows and alumni that have collectively raised over $2.4 billion in public and private funding since the organization was founded in 2015.

“The success of Activate Fellows is ample evidence that scientists and engineers have the talent and drive to face global challenges head-on,” adds Activate chief fellowship officer, Brenna Teigler. “Our diverse fellows are transforming technical breakthroughs into businesses across the United States in 26 states across a range of sectors spanning carbon management, semiconductors, manufacturing, energy, chemicals, ocean tech, and more.”

The application is available online, and fellows will be selected in April of next year. The 2025 program will begin in June.

Activate is looking for local and regional early-stage founders — who have raised less than $2 million in funding — who are working on high-impact technology. Each cohort consists of 10 fellows that join the program for two years. The fellows receive a living stipend, connections from Activate's robust network of mentors, and access to a curriculum specific to the program.

From events to a new climate-focused report, here are 3 things to know in Houston energy transition news

take note

Editor's note: Dive headfirst into the new week with three quick things to catch up on in Houston's energy transition: a roundup of events not to miss, a new study puts a dollar sign to Texas' disasters per capita, and three organizations are teaming up for an August event.

When it comes to weather-related events, Texas is expensive

Texas — home to everything from tornadoes to hurricanes — cracks the top 10 of a new report ranking states based on impact from weather-related events.

SmartAsset's new report factored in a myriad of data from the Federal Emergency Management Agency to identify which states face the most financial risk due to various weather events. In the report, the states were ranked by the total expected annual financial losses per person. Texas ranked at No. 10. In Texas, the total expected annual loss per person is estimated as $283.15.

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.
