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.

onboarding

A national hardtech-focused organization has named its 2024 batch of innovators, which includes the inaugural Houston-based cohort.

Activate named 62 fellows and 50 companies for is latest class, which spans Berkley, California — where the organization is based, Boston, New York, and Houston. Additionally, Activate Anywhere, the program's virtual and remote cohort, was named. According to Activate, it received over 1,000 applicants.

“People, not ideas alone, move the world forward. It is through the drive and determination of brilliant scientists and engineers that we are witnessing true progress,” says Activate CEO Cyrus Wadia in a news release. “Our current Activate Fellows and alumni are already pioneering innovative solutions that make a measurable difference. We’re thrilled to support the next 62 visionaries who will lead the charge in addressing our most urgent issues through groundbreaking science and technology.”

It's the first year Activate has hosted a Houston-based cohort. The organization initially announced its expansion early last year. The inaugural cohort has 11 fellows across energy, materials, life sciences, space, and other sectors.

The named Houston fellows who are working on energy transition solutions include:

1PointFive signs latest deal, shares update on $1.3B carbon removal project

DAC deal

Houston-based 1PointFive, a subsidiary of Occidental Petroleum Corp., has secured another buyer of carbon dioxide removal credits for its $1.3 billion STRATOS project as it moves toward operation.

Bain & Company, a Boston-based consulting firm, has agreed to purchase 9,000 metric tons of carbon dioxide removal (CDR) credits from the direct air capture (DAC) facility over three years, according to a news release. DAC technology pulls CO2 from the air at any location, not just where carbon dioxide is emitted.

The deal is Bain's first purchase of DAC removal credits. The company has developed a program that helps clients purchase carbon credits from a range of carbon-removal technologies.

"We are proud to partner with 1PointFive and add them to our portfolio of engineered carbon removal technologies," Sam Israelit, Bain’s chief sustainability officer, said in the news release. "Their track record for developing DAC technology, coupled with their deep understanding of what it takes to deliver large-scale infrastructure projects, uniquely positions them to be a leader in this emerging segment.”

“We believe this agreement demonstrates continued momentum for the solution while supporting the development of vital domestic infrastructure,” Anthony Cottone, president and general manager of 1PointFive, added in the release.

Bain joins others like Microsoft, Amazon, AT&T, Airbus, the Houston Astros and the Houston Texans that have agreed to buy CDR credits from STRATOS.

The Texas-based STRATOS project is being developed through a joint venture with investment manager BlackRock and is designed to capture up to 500,000 metric tons of CO2 per year. The U.S Environmental Protection Agency approved Class VI permits for the project last year.

1PointFive says STRATOS is "progressing through start-up activities." The company shared in a LinkedIn post that Phase 1 of the project is expected to go online in Q2, with Phase 2 ramping up through the remainder of 2026.

Houston researcher develops efficient method to cool AI data centers

cool findings

A University of Houston professor has developed a new cooling method that can remove heat at least three times more effectively from AI data centers than current technologies.

Hadi Ghasemi, a distinguished professor of Mechanical & Aerospace Engineering at UH, published his findings in two articles in the International Journal of Heat and Mass Transfer. The findings solve a critical issue in the growing AI sector, according to UH.

High-powered AI data centers generate huge amounts of heat due to the GPU and operating systems they use with extreme power densities, which introduce complex thermal challenges. Traditionally, cooling methods, like microchannels, which use flow and spray cooling, have had limitations when exposed to extreme heat flux, according to UH.

Ghasemi’s research, however, found a more effective way to design thin-film evaporation structures to release heat from data centers and electronics at record performance.

Ghasem’s solution coupled topology optimization and AI modeling to determine the best shapes for thin film efficiency, ultimately landing on a branch-like structure—resembling a tree.

The model found that the “branches” needed to be about 50 percent solid and 50 percent empty space for optimum efficiency, and that they could sustain high heat fluxes with minimal thermal resistance.

“These structures could achieve high critical heat flux at much lower superheat compared to traditionally studied structures,” Ghasemi said in a news release. “The new structures can remove heat without having to get as hot as previous removal systems.

Ghasemi’s doctoral candidates, Amirmohammad Jahanbakhsh and Saber Badkoobeh Hezave, also worked on the project. The team believes their results show the impact of a physics-aware, AI design and can help ensure reliability, longevity and stability of AI data centers.

“Beyond achieving record performance, these new findings provide fundamental insight into the governing heat-transfer physics and establishes a rational pathway toward even higher thermal dissipation capacities,” Ghasemi added in the release

Texas federal judge allows lawsuit against California AG over ExxonMobil remarks

In the News

A federal judge in Texas ruled that ExxonMobil can bring a defamation lawsuit against California’s attorney general over comments about the company’s plastic recycling efforts.

U.S. District Judge Michael J. Truncale in the Eastern District of Texas said in a ruling in February that California Attorney General Rob Bonta cannot claim official immunity in regards to several statements he made, including one in a campaign email sent to Texas residents.

Bonta sued Exxon in September 2024, saying that the oil giant encouraged consumers to purchase plastics products with the promise that the products would be recycled. He said less than 5% of plastic is recycled into another plastic product, and that recycling processes touted by Exxon don't work. Exxon said the problem is with California's recycling system.

Exxon later sued Bonta in his individual capacity and environmental groups for defamation, saying that the comments harmed current and future business contracts. The lawsuit was filed in Texas, near its principal place of business.

Truncale dismissed the lawsuit against the environmental groups but allowed it to proceed against Bonta.

The judge pointed to a campaign email Bonta sent to Texas residents saying that only 5% is recycled and the rest ends up in the environment and in our bodies: “Exxon Mobil knew, and Exxon Mobil lied.” Bonta, a Democrat, argued he was simply updating email recipients on his office's activities.

But Truncale said a campaign contribution link on the email turned the communication into a campaign activity not protected by immunity in Bonta's official capacity as attorney general.

“Here, the contribution request betrays the email's true nature: a campaign promotion. Campaigning is not within Bonta's scope of employment,” the judge wrote.

Bonta has filed a notice of appeal.

“The Attorney General looks forward to vigorously litigating this case, and is proud to advance his lawsuit against ExxonMobil,” his press office said.

ExxonMobil said in a statement that the “campaign of lies designed to derail our advanced recycling business must stop.”
