I truly appreciate the efforts of HETI and Greater Houston Partnership for their continuous efforts to be at the forefront of Energy Transition.

Ion

The Ion has provided a perfect ecosystem for founders, researchers, innovators, investors and corporate leaders to build scalable enterprises.

Navigating the vibrant ecosystem of the Ion innovation hub in downtown Houston, I quickly realized its uniqueness. This hub isn’t just about co-working spaces or networking events; it offers a dynamic platform where founders and innovators come to life with their ideas. I sensed the entrepreneurial spirit in every corner, every discussion, and every presentation.

In my exploration, I discovered that startups, both budding and established, frequently have opportunities to pitch their ideas. This isn’t just a standard pitch session; it’s a transformative experience. Founders present their innovations and visions to an audience that’s a blend of seasoned professionals, industry experts, and potential investors. Each pitch session felt like a grand performance, filled with passion, determination, and vision.

What’s even more impressive is how these sessions cater to investors. For them, the Ion hub becomes a treasure trove of opportunities. As an investor, sifting through numerous pitches can be a daunting task. But here, the environment ensures they witness only the most promising and aligned pitches, allowing them to identify the right investment opportunities that match their portfolios and interests.

The frequency of these pitches ensures a continuous flow of fresh ideas, and as a founder, you’re always in front of an audience that matters. It’s a win-win: founders get regular feedback and potentially find the right partners, while investors stay updated with the latest innovations and can quickly spot the next big thing.

Immersing myself in this environment, I felt the palpable excitement. Founders eagerly prepping for their pitches, investors actively engaged in discussions, and the continuous buzz of potential collaborations. The Ion hub has successfully created a space where ideas meet capital, where dreams meet reality, and where every pitch could be the beginning of the next big success story.

Greentown Labs

As I delved deeper into the ecosystem of Greentown Labs after my engagement with The Ion, I was struck by the holistic approach this hub takes toward nurturing innovation. Beyond being a space for clean tech and sustainable ventures, Greentown Labs offers a myriad of resources tailored for startups.

One of the standout features is their state-of-the-art prototyping labs. Founders have access to cutting-edge equipment, enabling them to transform their visionary ideas into tangible prototypes, fast-tracking the path from concept to realization.

But it’s not just about physical resources. Greentown Labs champions a collaborative ethos. Shared resources mean startups can lean on each other, pooling knowledge and skills and fostering an environment of mutual growth. This spirit of collaboration extends to their mentorship programs. New ventures can tap into a wealth of experience, gaining insights and guidance from seasoned professionals who’ve walked the path before.

Engaging with founders from CLS Wind and Mars Materials, it became evident how such an integrated support system propels their ambitions. Greentown Labs, in essence, is more than just a hub; it’s a community. A community where sustainability meets innovation, where ideas are nurtured with the right tools and mentorship, and where the future of clean tech is being crafted.

A special thank you to Jane Stricker from Houston Energy Transition Initiative (HETI), whose passion and vision for a sustainable energy future left a profound impact on me; Kay McCall from Renewable Energy Alliance – Houston, whose leadership and insights were truly enlightening; Barbara Burger, whose innovative approach to bridging traditional energy with emerging technologies is commendable; and Joey Sanchez from Ion Houston, whose deep understanding of Houston’s business ecosystem and dedication to fostering change enriched my perspective immensely. Each of you played a pivotal role in making my experience memorable and filled with invaluable learnings. Thank you for your time, willingness to share, and for being such inspiring figures in this transformative journey Houston is undertaking.

In reflecting upon my journey through Houston’s energy landscape, it’s evident that the city stands on the cusp of a transformative era. The concerted efforts of organizations like HETI, Ion, and Greentown Labs exemplify Houston’s unwavering commitment to reimagining its energy identity. This isn’t just about evolving from its storied past as the “Energy Capital of the World.” It’s about setting the gold standard for what energy transition on a global scale looks like. Houston’s evolution, fueled by innovation, collaboration, and sheer determination, sends a resounding message to the world: the energy transition is not just feasible; it’s already underway. The endeavors and successes in this space are a testament to Houston’s vision and resilience, proving that any city can redefine its narrative with the right framework and community. As I conclude my reflections, I’m filled with a profound sense of optimism. Houston, you’ve not only lived up to your legacy but are also charting a new course that will inspire generations to come.

The accolades keep rolling in for Houston-based Fervo Energy, a producer of geothermal power.

Fervo lands at No. 6 on Time magazine and Statista’s new list of America’s Top GreenTech Companies of 2025. The ranking recognizes sustainability-focused companies based on factors such as impact, financial strength, and innovation.

Time notes that Fervo broke ground in 2023 in Utah on what the company claims will be the world’s largest geothermal plant. The plant is scheduled to start supplying carbon-free electricity to the grid next year and to reach its 400-megawatt capacity in three years.

“Technologies like this only make a difference if we deploy them at large-scale in a way that can reduce carbon emissions and increase the reliability of the grid,” Fervo CEO Tim Latimer told Time in 2023.

The startup was named North American Company of the Year by research and consulting firm Cleantech Group for 2025. Fervo topped the Global Cleantech 100, Cleantech Group’s annual list of the world’s most innovative and promising cleantech companies.

Last year, Fervo also made Time’s list of the 200 Best Inventions of 2024. Fervo was recognized in the green energy category for its FervoFlex geothermal power system.

Founded in 2017, Fervo is now a unicorn, meaning its valuation as a private company exceeds $1 billion. The startup’s valuation is estimated at $1.4 billion. According to PitchBook data, the company raised $634 million in the fourth quarter of 2024.

In all, eight Houston-area companies appear among the top 250 greentech companies ranked by Time and Statista. Other than Fervo, they are:

  • No. 43 Lancium Technologies, an energy storage and distribution company
  • No. 50 Solugen, a producer of sustainable chemicals.
  • No. 56 Quaise Energy, which specializes in terawatt-scale geothermal power.
  • No. 129 Plus Power, a developer, owner and operator of battery storage projects.
