Houston company secures $100M for 'world’s largest geothermal energy plant'

loan guarenteed

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.

Artist collective brings carbon-absorbing murals to Houston

seeing green

Anthony Rose, the CEO of creative agency United By Design, is on a mission to brighten Houston’s urban spaces and improve the city’s air quality one carbon-absorbing mural at a time.

Rose originally founded United By Design, or UXD, in 2019 to connect muralists like himself and commercial businesses seeking to beautify their spaces and form brand identities. After creating vibrant murals for Lockhart Elementary School, the Houston Astros, and Smoothie King, Rose expanded UXD’s vision to include environmental sustainability in their artistic collaborations in 2022.

“This city’s vibrant art scene and growing focus on sustainability makes it an ideal location for our projects,” Rose says. “We’re not just creating eco-friendly murals, we’re reimagining how art can actively contribute to environmental solutions.”

In search of ecologically-conscious paints, Rose formed a partnership with Spain-based, natural paint company Graphenstone. Rose says he was drawn to the company’s eponymous Graphenstone coating because of its nontoxic ingredients and exclusively uses the product for UXD’s carbon-absorbing murals.

For 713 Day, UXD created carbon-absorbing mural "(HUE)STON HARMONY" in collaboration with Downtown Houston+ and local artist David Maldonado. Photo courtesy of Egidio Narvaez

The Graphenstone coating consists of a limestone base which goes through a process called photocatalysis, during which carbon dioxide from the atmosphere is absorbed into the surface, and is then sealed in with graphene, a thin layer of carbon atoms. The murals absorb carbon dioxide throughout the coat’s drying process which typically takes 30 days.

“Each of our murals absorbs about 1600 grams of CO2 during that curing process which is the equivalent daily absorption of about 33 growing trees,” Rose explains.

UXD’s largest carbon-absorbing mural to date is a floor-to-ceiling panorama in downtown Houston’s historic Mellie Esperson building, home to the company’s new creative hub. Painted by Houston-born artist Emily Ding, the mural is a tribute to the establishment’s namesake: an innovative, early 20th century entrepreneur who constructed the opulent building.

Rose says UXD plans to expand their carbon-absorbing murals project in collaboration with more local artists and establishments, while creating an artist-in-residency program themed around sustainability. Though Rose acknowledges in the grand scheme of carbon pollution these murals are not a silver bullet, he says the non-toxic paints are encouraging conversations about how artists can be conservation-minded.

“We’re trying to figure out how art as a messaging tool can help break down scientific data, a language not many people practice daily, can break down barriers and help bridge the gap to a more intuitive knowledge of sustainability,” Rose says. “We’re bringing the community together, helping them feel empowered, and giving them actionable information to help them live more sustainable lives.”

Texas ride-hailing app grows Houston fleet with EV additions

rolling out

Your next Alto ride might be electric. The Dallas-based car service has rolled out electric vehicles in Houston.

Alto, founded in Dallas in 2018 and launched in Houston in 2020, elevates ridesharing with its own fleet of company-owned, clearly branded SUVs driven by its staff of drivers. The company previously announced its plans to evolve its fleet into being completely electric, and the first EVs have hit the road, according to a company email.

"Our EV additions to the Houston fleet mark an important moment in our commitment to significantly reduce Alto's environmental impact," reads the email sent on September 5.

The new cars offer similar features to its existing fleet, including legroom, phone chargers, water bottles for riders, and more. Plus, the new cars — Kia EV9 — boast a quieter ride.

Alto has consistently grown in its Texas markets — which include Houston and Dallas — over the years, including expanding into Houston's suburbs.

Will Coleman, CEO of Alto, previously wrote in a guest column for InnovationMap that his priorities for starting the company included safety — but also sustainability. For years, Alto has been expressing interest in introducing EVs, with plans of having a completely electric fleet.

"This EV vision is one example of how a rideshare company can build a better and more accountable industry, and these steps also give Houstonians a more responsible and sustainable transportation solution," Coleman writes.

Fervo was among Congruent Ventures’ and Silicon Valley Bank’s 50 by 2050 companies, all of which are poised to advance global decarbonization over a 25-year span

Just last month, Fervo secured $421 million in debt financing for the construction of its 500-megawatt Cape Station geothermal project in Utah. And in December, the company landed an oversubscribed $462 million Series E round of funding, pushing its valuation to an estimated $1.4 billion. Fervo filed for an IPO earlier this year.

3 strategies to strengthen the Gulf Coast as a global energy hub

The View from HETI

The Texas-Louisiana Gulf Coast is the backbone of America’s energy and chemical economy. Texas produces roughly 43% of U.S. crude oil and 28% of natural gas, while Texas and Louisiana together account for about half of the nation’s refining capacity, processing 9.3 million barrels of crude per day across 50 refineries. The region also produces approximately 80% of the nation’s primary petrochemicals and ships more than $117 billion in chemical products annually from Texas alone.

This unmatched concentration of refining, petrochemical manufacturing, pipelines, ports, and technical talent makes the Gulf Coast one of the most critical energy hubs in the world. But maintaining that leadership in a rapidly evolving global market will require intentional collaboration, faster technology commercialization, and strengthened supply chain resilience.

In fall 2025, the Greater Houston Partnership’s Houston Energy Transition Initiative (HETI) convened national laboratories, Gulf Coast universities, and industry leaders to examine how to reinforce the region’s long-term competitiveness. Participants included Argonne, Oak Ridge, Lawrence Berkeley, the National Energy Technology Laboratory (NETL), and the National Laboratory of the Rockies, alongside Gulf Coast academic institutions and energy and chemical companies. Here are the key findings and takeaways from the workshop.

1. Supply Chain Resilience Requires Structured Industry–Lab Collaboration

Resilience—diversity of supply, operational flexibility, and rapid recovery—was a recurring theme. Recent disruptions exposed vulnerabilities in tightly interconnected energy and manufacturing systems.

National laboratories provide capabilities that complement Gulf Coast industrial scale, particularly at early and mid technology readiness levels (TRLs 1–7), before full commercial deployment. Examples include:

Advanced manufacturing and AI-enabled validation of critical components (Oak Ridge).
Materials scale-up and techno-economic modeling to move from lab discovery to industrial relevance (Argonne).
Pilot-scale testing for severe-service alloys, chemical conversion, and process innovation (NETL).
Integrated energy systems modeling to assess grid resilience and system disruptions (National Laboratory of the Rockies).

Recommendation: Organize targeted Gulf Coast industry missions to national laboratories focused on critical supply chains—power equipment, high-heat industrial processes, novel catalysts, refining, and grid infrastructure—to identify joint development opportunities and reduce time to commercialization.

2. Modeling, AI, and Open-Access Platforms Can Bridge the Technology Gap

A persistent barrier to innovation is the gap between scientific discovery, applied development, and commercial deployment. Universities often operate at TRLs 1–3, national labs at 1–7, and industry at 7–9. Bridging these silos requires shared modeling tools, high-performance computing, and structured feedback loops.

National labs maintain open-access platforms capable of:

Simulating grid expansion, investment, and dispatch decisions.
Modeling cradle-to-gate industrial material flows.
Optimizing complex energy and chemical systems.
De-risking carbon capture, critical mineral recovery, and advanced manufacturing integration.

Recommendation: HETI should convene structured training and feedback sessions on these public modeling platforms—ensuring Gulf Coast industry can apply, improve, and help guide further development of tools critical to regional competitiveness. Federal initiatives such as the Genesis Mission, focused on AI-accelerated scientific discovery, further expand opportunities for Gulf Coast participation.

3. Time to Commercialization Is the Ultimate Competitive Metric

The lithium-ion battery is a cautionary example: while pioneered in U.S. labs, large-scale manufacturing leadership shifted overseas. Without strategic intervention, U.S. firms are projected to capture less than 30% of domestic lithium battery cell value by 2030.

Successful DOE-backed consortium models show that mission-aligned, multi-partner collaboration reduces development timelines and strengthens domestic manufacturing know-how. However, public–private partnership mechanisms such as CRADAs and Strategic Partnership Projects can be time-intensive.

Recommendation: The Gulf Coast should actively engage DOE and national laboratories to streamline public–private partnership pathways, improve intellectual property clarity, and expand industry access to laboratory infrastructure.

The Path Forward: A Gulf Coast Consortium Model
The workshop’s central conclusion was clear: the Gulf Coast should formalize collaboration through a regional industry–academia–laboratory consortium.

Such a model could:

Co-locate national lab researchers within the region.
Share modeling data and analytical capabilities.
Establish open-access pilot facilities that complement lab infrastructure.
Harmonize IP frameworks to accelerate licensing and deployment.

With its dense industrial ecosystem, technical workforce, and decision-making concentration, the Gulf Coast is uniquely positioned to serve as a national demonstration hub for advanced energy and chemical manufacturing.

If industry, universities, and national laboratories align around a shared regional strategy, the Gulf Coast can:

Accelerate commercialization timelines.
Strengthen critical supply chains.
Unleash a world-class technical workforce.
Reinforce U.S. leadership in strategic energy and chemical sectors.
