Houston-based geothermal energy company Fervo Energy has secured a $100 million bridge loan for the first phase of its ongoing project in Utah.

The loan came from an affiliate of Irvington, New York-based X-Caliber Rural Capital. Proceeds will support construction of Fervo’s Cape Station project, which is being touted as the world’s largest geothermal energy plant.

The first phase of Cape Station, which is on track to generate 90 megawatts of renewable energy, is expected to be completed in June 2026. Ultimately, the plant is supposed to supply 400 megawatts of clean energy by 2028 for customers in California.

“Helping this significant project advance and grow in rural America is a true testament to how investing in communities and businesses not only has local influence, but can have a global, long-lasting impact by promoting sustainability and stimulating rural economies,” Jordan Blanchard, co-founder of X-Caliber Rural Capital, says in a news release.

X-Caliber Rural Capital is an affiliate of commercial real estate financing company X-Caliber Capital Holdings.

Fervo says its drilling operations Utah’s Cape Station show a 70 percent reduction in drilling times, paving the way for advancement of its geothermal energy system.

Tim Latimer, co-founder and CEO of Fervo, says his company’s drilling advancements, purchase deals, transmission rights, permit approvals, and equipment acquisitions make Fervo “an ideal candidate” for debt financing. In May, Latimer joined the Houston Innovators Podcast to discuss the company's growth and latest project.

With a new office in downtown Houston, Fervo recently signed up one of the country’s largest utilities as a new customer and expanded its collaboration with Google.

To date, Fervo has raised $531 million in venture capital funding, per Crunchbase data.

Houston ranked a top market for attracting funding for sustainability-focused startups

by the numbers

From a financial standpoint, Houston appears to be a sustainable environment for sustainability-focused startups.

An analysis by PromoLeaf, a retailer of sustainable promotional products, that came out at the end of last year ranks Houston fourth among U.S. cities for the average funding raised by locally based startups in the sustainability sector, according to Crunchbase data.

Per the report, the Bayou City attracts $150.7 million in sustainability funding for startups. Ahead of Houston are Salt Lake City with $204.5 million; Santa Monica, California, with $154.3 million; and Fremont, California, with $153.4 million.

PromoLeaf’s analysis features cities where at least 20 companies are focused on sustainability.

The analysis indicates Houston has 20.6 sustainability startups per 100,000 residents. Ranking first in that regard is Boulder, Colorado (115 per 100,000 residents).

While Houston trails Boulder by a long distance, it fares well among the Texas cities in the analysis:

  1. Austin, 26.2 sustainability startups per 100,000 residents
  2. Houston, 20.6 sustainability startups per 100,000 residents
  3. Midland, 18.8 sustainability startups per 100,000 residents
  4. Plano, 11.9 sustainability startups per 100,000 residents
  5. Dallas, 11 sustainability startups per 100,000 residents
  6. Fort Worth, 5.3 sustainability startups per 100,000 residents
  7. San Antonio, 5.2 sustainability startups per 100,000 residents

PromoLeaf says more than 21,600 sustainability startups operate in the U.S. They’re in the renewable energy, recycling and pollution control, environmental engineering, green consumer goods, and environmental consulting industries.

The analysis shows Houston has:

  • 13.7 renewable energy startups per 100,000 residents
  • 5.8 recycling and pollution control startups per 100,000 residents
  • 3.5 environmental engineering startups per 100,000 residents
  • 2.9 environmental consulting startups per 100,000 residents
  • 0.70 green consumer goods startups per 100,000 residents

According to the Greater Houston Partnership, renewable energy startups leading Houston’s energy transformation include Energy Transition Ventures, Fysikes Biosolutions, Ionada, Katz Water Technologies, Pressure Corp., and Renewell Energy.

“A dynamic business climate combined with growth in venture capital funding in Houston has created fertile ground for companies of all stages aiming to power our world through the global energy transition,” the partnership says. “As the Energy Capital of the World, Houston has become a hub for startups and venture capital firms investing in the region’s energy future.”

Outside the energy sector, Houston startups like Trendy Seconds also are making their mark in sustainability. The company runs an online marketplace where women can find preowned clothing or shop for new clothing from sustainable brands.

“Our ultimate goal is to make responsible consumption super easy,” Maria Burgos, founder of Trendy Seconds, told InnovationMap last year.

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.”

Houston startup debuts sustainable, bio-based 'leather' fashions

sustainable fashion

Last month, Houston-based Rheom Materials and India’s conscious design studio Econock unveiled a collaborative capsule collection that signaled more than just a product launch.

Hosted at Lineapelle—long considered the global epicenter of the world's premier leather supply chain—in the vaulted exhibition halls of Rho-Fiera Milano, the collection centered around Rheom’s 91 percent bio-based leather alternative, Shorai.

It was a bold move, one that shifted sustainability from a concept discussed in panel sessions to garments that buyers could touch and wear.

The collection featured a bomber-style jacket, an asymmetrical skirt and a suite of accessories—all fabricated from Shorai.

The standout piece, a sculptural jacket featuring a funnel neck and dual-zip closure, was designed for movement, challenging assumptions about performance limitations in bio-based materials. The design of the asymmetrical skirt was drawn from Indian armored warrior traditions, according to Rheom, with biodegradable corozo fasteners.

Built as a modular wardrobe rather than isolated pieces, the collection reflects a shared belief between Rheom and Econock in designing objects that adapt to daily life, according to the companies.

The collection was born out of a new partnership between Rheom and Econock, focused on bringing biobased materials to the market. According to Rheom, the partnership solves a problem that has stalled the adoption of many next-gen textiles: supply chain friction.

While Rheom focuses on engineering scalable bio-based materials, New Delhi-based Econock brings the complementary design and manufacturing ecosystem that integrates artisans, circular materials and production expertise to translate the innovative material into finished goods.

"This partnership removes one of the biggest barriers brands face when adopting next-generation materials,” Megan Beck, Rheom’s director of product, shared in a news release. “By reducing friction across the supply chain, Rheom can connect brands directly with manufacturers who already know how to work with Shorai, making the transition to more sustainable materials far more accessible.”

Sanyam Kapur, advisor of growth and impact at Econock, added: “Our partnership with Rheom Materials represents the benchmark of responsible design where next-gen materials meet craft, creativity, and real-world scalability.”

Rheom, formerly known as Bucha Bio, has developed Shorai, a sustainable leather alternative that can be used for apparel, accessories, car interiors and more; and Benree, an alternative to plastic without the carbon footprint. In 2025, Rheom was a finalist for Startup of the Year in the Houston Innovation Awards.

Shorai is already used by fashion lines like Wuxly and LuckyNelly, according to Rheom. The company scaled production of the sugar-based material last year and says it is now produced in rolls that brands can take to market with the right manufacturer.
