From finding funding to navigating the pace of traditional oil and gas company tech adoption, energy transition companies face their fair share of challenges.

This year's Houston Innovation Awards finalists in the Energy Transition category explained what their biggest challenge has been and how they've overcome it. See what they said below, and make sure to secure your tickets to the Nov. 14 event to see which of these finalists win the award.

"The evolving nature of the energy industry presents opportunities to solve some of our industry's greatest challenges. At Amperon we help optimize grid reliability and stability with the power of AI demand forecasting."

— Sean Kelly, CEO of Amperon, an AI platform powering the smart grid of the future

"The biggest challenge in leading an energy transition-focused startup has been balancing the urgency for sustainable solutions with the slow pace of change in traditional industries like oil and gas. Many companies are cautious about adopting new technologies, especially when it comes to integrating sustainability initiatives. We overcame this by positioning our solutions not just as environmentally friendly, but as tools that improve safety, efficiency, and cost savings. By aligning our value proposition with their operational goals and demonstrating real, measurable benefits, we were able to gain traction and drive adoption in industries that are traditionally resistant to change."

— Dianna Liu, CEO of ARIXTechnologies, an integrated robotics and data analytics company that delivers inspection services through its robotics platforms

"Scaling up production of hard tech is a major challenge. Thankfully, we recruited top-notch talent with experience in technology scale-up and chemical processes. In addition, we've begun building partnerships with some of the world's largest chemical manufacturers in our space who are excited to be a part of our journey and could rapidly accelerate our go to market strategy. We have significant demand for our product as early as 2025, so partnering with these companies to scale-up will bring our technology to market years ahead of doing it alone."

— Matthew Dawson, CEO of Elementium Materials, a battery technology with liquid electrolyte solutions

"Our pyrolysis reactor is a proprietary design that was developed during Covid. We ran simulations to prove that it works, but it was not easy to test it in a pilot facility, let alone scaling it up. We managed ... to run our pilot plant studies, while working with them remotely. We proved that our reactor worked and produced high quality products. Later, we built our own pilot plant R&D facility to continue running tests and optimizing the process. Then, there was the challenge of scaling it up to commercial size. ... We put together a task force of four different companies to come together to design and build this complex reactor in record time."

— Vibhu Sharma, CEO of InnoVent Renewables, a startup with proprietary continuous pyrolysis technology that converts waste tires, plastics, and biomass into valuable fuels and chemicals

"Energy storage and geothermal power generation are capital-intensive infrastructure projects, requiring investors with a deep commitment and the patience in terms of years to allow the technology to be developed and proven in the field. One challenge is finding that niche of investors with the vision to join our journey. We have succeeded in raising our $30 million series A with these types of investors, whom we’re confident will continue the journey as we scale."

— Cindy Taff, CEO of Sage Geosystems, an energy company focused on developing and deploying advanced geothermal technologies to provide reliable power and sustainable energy storage solutions regardless of geography

"The biggest challenge we've faced has been to bring together massive independent power producers on one side who are investing hundreds of millions of dollars into grid infrastructure with multi- national tech giants on the other that don't have experience working much with energy storage. As a startup with only four employees, gaining credibility with these players was critical. We overcame this hurdle by becoming the preeminent thought leader on storage emissions, through publishing white papers, discussing the issues on podcasts, and (more)."

Houston-based ENGIE to add new wind and solar projects to Texas grid

coming soon

Houston-based ENGIE North America Inc. has expanded its partnership with Los Angeles-based Ares Infrastructure Opportunities to add 730 megawatts of renewable energy projects to the ERCOT grid.

The new projects will include one wind and two solar projects in Texas.

“The continued growth of our relationship with Ares reflects the strength of ENGIE’s portfolio of assets and our track record of delivering, operating and financing growth in the U.S. despite challenging circumstances,” Dave Carroll, CEO and Chief Renewables Officer of ENGIE North America, said in a news release. “The addition of another 730 MW of generation to our existing relationship reflects the commitment both ENGIE and Ares have to meeting growing demand for power in the U.S. and our willingness to invest in meeting those needs.”

ENGIE has more than 11 gigawatts of renewable energy projects in operation or under construction in the U.S. and Canada, and 52.7 gigawatts worldwide. The company is targeting 95 gigawatts by 2030.

ENGIE launched three new community solar farms in Illinois since December, including the 2.5-megawatt Harmony community solar farm in Lena and the Knox 2A and Knox 2B projects in Galesburg.

The company's 600-megawatt Swenson Ranch Solar project near Abilene, Texas, is expected to go online in 2027 and will provide power for Meta, the parent company of social media platform Facebook. Late last year, ENGIE also signed a nine-year renewable energy supply agreement with AstraZeneca to support the pharmaceutical company’s manufacturing operations from its 114-megawatt Tyson Nick Solar Project in Lamar County, Texas.

Houston geothermal company raises $97M Series B

fresh funding

Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.

Houston expert discusses the clean energy founder's paradox

Guest Column

Everyone tells you to move fast and break things. In clean energy, moving fast without structural integrity means breaking the only planet we’ve got. This is the founder's paradox: you are building a company in an industry where the stakes are existential, the timelines are glacial, and the capital requires patience.

The myth of the lone genius in a garage doesn’t really apply here. Clean energy startups aren’t just fighting competitors. They are fighting physics, policy, and decades of existing infrastructure. This isn’t an app. You’re building something physical that has to work in the real world. It has to be cheaper, more reliable, and clearly better than fossil fuels. Being “green” alone isn’t enough. Scale is what matters.

Your biggest risks aren’t competitors. They’re interconnection delays, permitting timelines, supply chain fragility, and whether your first customer is willing to underwrite something that hasn’t been done before.

That reality creates a brutal filter. Successful founders in this space need deep technical knowledge and the ability to execute. You need to understand engineering, navigate regulation, and think in terms of markets and risk. You’re not just selling a product. You’re selling a future where your solution becomes the obvious choice. That means connecting short-term financial returns with long-term system change.

The capital is there, but it’s smarter and more demanding. Investors today have PhDs in electrochemistry and grid dynamics. They’ve been burned by promises of miracle materials that never left the lab. They don't fund visions; they fund pathways to impact that can scale and make financial sense. Your roadmap must show not just a brilliant invention, but a clear, believable plan to drive costs down over time.

Capital in this sector isn’t impressed by ambition alone. It wants evidence that risk is being retired in the right order — even if that means slower growth early.

Here’s the upside. The difficulty of clean energy is also its strength. If you succeed, your advantage isn’t just in software or branding. It’s in hardware, supply chains, approvals, and years of hard work that others can’t easily copy. Your real competitors aren’t other startups. They’re inertia and the existing system. Winning here isn’t zero-sum. When one solution scales, it helps the entire market grow.

So, to the founder in the lab, or running field tests at a remote site: your pace will feel slow. The validation cycles are long. But you are building in the physical world. When you succeed, you don’t have an exit. You have a foundation. You don't just have customers; you have converts. And the product you ship doesn't just generate revenue; it creates a legacy.

If your timelines feel uncomfortable compared to software, that’s because you’re operating inside a system designed to resist change. And let’s not forget you are building actual physical products that interact with a complex world. Times are tough. Don’t give up. We need you.
