The following was written by Pavan Kumar Medepalli, MBA candidate at UNC Kenan-Flagler Business School.

As I reflect on my past visit to Houston, it’s not the usual sights or activities that linger but the pulse of a city redefining its energy narrative. The vibrant energy, the breakthroughs in innovation, and the spirited conversations with passionate individuals left an indelible mark. To my LinkedIn community, I invite you to join me on this journey into the heart of Houston’s transformative landscape.

Houston, traditionally known as the “Energy Capital of the World,” is now pioneering a new path. My recent trip provided a deep dive into its evolution from a primary energy hub to a beacon of global energy transition. At the forefront of this change are entities like HETI, Ion, Renewable Energy Alliance Houston, and Greentown Labs, each shaping a vibrant ecosystem of innovation.

During my recent three-day trip to Houston, I had the incredible opportunity to immerse myself in some of the city’s most groundbreaking and influential spaces dedicated to energy innovation and sustainability. The experience was nothing short of transformative, and I’m eager to share some of the highlights and personal takeaways from this journey.

Houston Energy Transition Initiative (HETI):

HETI, with its compelling mission to revolutionize the energy landscape, stands out as a beacon of Houston’s dedication to sustainable change. This initiative capitalizes on Houston’s rich energy heritage, tapping into its vast infrastructure, expertise, and financial prowess, aiming to facilitate the global transition towards a cleaner, sustainable energy future.

One of the highlights of my trip was the privilege of interacting with Jane Stricker, Vice President of HETI. Her insights were invaluable. As the VP elaborated, HETI’s goal is not just about innovating for cleaner energy but establishing a framework where the transition is inclusive, impactful, and resilient. The organization aims to bring together diverse stakeholders, from industry stalwarts to budding researchers, forging a collective vision for the energy future.

It was quite interesting to know that HETI is backed by its member companies like ExxonMobil, Chevron, BP, SABIC and their strategy is to:

  • Jumpstart efforts in the sectors where Houston has a strategic advantage, Like CCUS, Clean Hydrogen, Circular Economy, and Energy Storage Solutions.
  • Attract and support companies in established new energy industries like Wind, Solar, RNG, Low-carbon LNG, and biofuels.

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.

Houston biotech company continues to expand in Brazil with new research partner

global expansion

Houston biotech company Cemvita has announced a strategic collaboration with Brazilian sustainable research institution REMA.

The move aims to promote Cemvita’s platform for evaluating and testing carbon waste streams as feedstocks for producing sustainable oil, according to the company.

Cemvita utilizes synthetic biology to transform carbon emissions into valuable bio-based chemicals. REMA professors Marcio Schneider and Admir Giachini have previously worked with Cemvita’s CTO, Marcio Busi da Silva, for approximately 20 years.

“This long-standing partnership reflects not only our strong professional ties, but also our shared commitment to advancing science and technology for a more sustainable future," Busi da Silva said in a news release.

REMA’s center is based in Florianópolis and is affiliated with the Federal University of Santa Catarina, which develops cost-effective environmental and technological solutions in automation, chemical engineering, biotech, environmental engineering and agronomy.

“Partnering with REMA in Florianópolis represents a significant step forward in our mission to transform carbon waste into valuable resources,” Tara Karimi, chief science and sustainability officer of Cemvita, said in a news release. “Together, we will enhance our platform’s capabilities, leveraging REMA’s expertise to evaluate and utilize diverse waste streams for sustainable oil production, further advancing the circular bioeconomy in Brazil and beyond.”

Cemvita recently expanded to Brazil to capitalize on the country’s progressive regulatory framework, which includes Brazil’s Fuel of the Future Law. The expansion also aimed to coincide with the 2025 COP30, the UN’s climate change conference, which will be hosted in Brazil in November.

Cemvita became capable of generating 500 barrels per day of sustainable oil from carbon waste at its first commercial plant in 2024, and as a result, Cemvita quadrupled output at its Houston plant. The company originally planned to reach this milestone in 2029.

Also in 2025, Cemvita announced a partnership with Brazil-based Be8 that focused on converting biodiesel byproduct glycerin into low-carbon feedstock to help support the decarbonization of the aviation sector. Cemvita agreed to a 20-year contract that specified it would supply up to 50 million gallons of SAF annually to United Airlines in 2023.

3 Houston energy companies rank among most innovative startups in Texas

report card

Three Houston companies claimed spots on LexisNexis's 10 Most Innovative Startups in Texas report, with two working in the geothermal energy space.

Sage Geosystems claimed the No. 3 spot on the list, and Fervo Energy followed closely behind at No. 5. Fintech unicorn HighRadius rounded out the list of Houston companies at No. 8.

LexisNexis Intellectual Property Solutions compiled the report. It was based on each company's Patent Asset Index, a proprietary metric from LexisNexis that identifies the strength and value of each company’s patent assets based on factors such as patent quality, geographic scope and size of the portfolio.

Houston tied with Austin, each with three companies represented on the list. Caris Life Sciences, a biotechnology company based in Dallas, claimed the top spot with a Patent Asset Index more than 5 times that of its next competitor, Apptronik, an Austin-based AI-powered humanoid robotics company.

“Texas has always been fertile ground for bold entrepreneurs, and these innovative startups carry that tradition forward with strong businesses based on outstanding patent assets,” Marco Richter, senior director of IP analytics and strategy for LexisNexis Intellectual Property Solutions, said in a release. “These companies have proven their innovation by creating the most valuable patent portfolios in a state that’s known for game-changing inventions and cutting-edge technologies.We are pleased to recognize Texas’ most innovative startups for turning their ideas into patented innovations and look forward to watching them scale, disrupt, and thrive on the foundation they’ve laid today.”

This year's list reflects a range in location and industry. Here's the full list of LexisNexis' 10 Most Innovative Startups in Texas, ranked by patent portfolios.

  1. Caris (Dallas)

Sage Geosystems has partnered on major geothermal projects with the United States Department of Defense's Defense Innovation Unit, the U.S. Air Force and Meta Platforms. Sage's 3-megawatt commercial EarthStore geothermal energy storage facility in Christine, Texas, was expected to be completed by the end of last year.

Fervo Energy fully contracted its flagship 500 MW geothermal development, Cape Station, this spring. Cape Station is currently one of the world’s largest enhanced geothermal systems (EGS) developments, and the station will begin to deliver electricity to the grid in 2026. The company was recently named North American Company of the Year by research and consulting firm Cleantech Group and came in at No. 6 on Time magazine and Statista’s list of America’s Top GreenTech Companies of 2025. It's now considered a unicorn, meaning its valuation as a private company has surpassed $1 billion.

Meanwhile, HighRadius announced earlier this year that it plans to release a fully autonomous finance platform for the "office of the CFO" by 2027. The company reached unicorn status in 2020.
