Whether you fuel up your car at the pump or a plug, you need to pay for it. One venture-backed Houston company is dedicated to optimizing that transaction process.

P97 was founded in 2012 to upgrade gas station payments — something that had remained stagnant since around 1997 with the card reader. Don Frieden, CEO and president at the company, thought more can be improved in this process and other daily transactions.

He shared his vision for the company — past, present, and future — on the Houston Innovators Podcast, as well as how he sees the relationship between fintech and the energy transition.

Tell me about the founding mission you had for P97 and the current technologies you're working on.

Don Frieden: P97 is my second software startup — both Houston-based companies. The first one was back in the late '90s, and we were leveraging technology to enable workforce automation and decisions for technology. I mentioned that just because it's relevant because fast forward, and that business was required by public traded company in 2008 and some of our learnings were about payments of gas technology, which led us to start this business.

With P97, our mission from the beginning was simplifying and energizing daily journeys. We think about daily journeys from the time we leave home in the morning and when we get back at the end of the day — whether it's tolling, parking, buying fuel, fast food restaurants, it's all a part of your daily journeys, and our goal is to make things a little bit simpler each day.

There hadn't been any payment innovation from the late '90s, and that was contactless payment at the gas pump, but nothing more until we started the business in 2012. Part of the reason the company name is P97 is because we wanted to innovate around payments since we really hadn't seen anything innovative since 1997.

One of the things we’re most excited about is voice enable payments through our partnership with Amazon's Alexa. The landscape of payments at gas stations underwent this next revolution, and we're using cutting-edge speech recognition and artificial intelligence to allow drivers to pay for fuel just using their voice. It makes the process faster and more efficient, and is completely hands-free. From this time I say, “Alexa, buy gas,” six seconds later, the gas would be turned on and any loyalty rewards I have would be applied, all from the comfort of my car.

How is P97 set up to address the energy transition and the new fuel sources coming out of it?

DF: The good news is about fuel is it's a process of filling up a vehicle — whether it's with a EV charge or whether you're putting hydrogen in the tank. We run one of the largest hydrogen networks in California now. Or, it’s just traditional fuel selling in gallons. The biggest challenge really is integrating all of those different use cases into mobile apps so families can have a wide variety of ways to to fuel their vehicles of wide variety of ways to pay for that fuel — all in one really frictionless experience.

How do you see Houston as a hub for your company as well as an energy transition leader?

DF: Houston is pretty much the energy capital of the world, so from from a partnership and client perspective, life is really easy in Houston right because we have so many major energy companies represented here, but we're not exactly a tech hub. Hiring in Houston has been a bit of a challenge. We have to sometimes hire people out of California and relocate them to Houston. Because of the high quality of life in Houston, we have been able to relocate people here and hire the very best talent.

The reality is that all these energy companies have now recognized the energy transition. Early on, electric vehicles were not overly popular, but now I think we all embrace the importance of climate change and zero hydrocarbon footprint. I think the last 24 months have seen really a major change in embracing everything from wind to solar to supporting the electrification of transportation. You've seen major investments by energy companies acquiring technology companies that can help them accelerate as they make the transition. It was maybe a little bit slow going early on, but the last couple of years, we've just watched it really accelerate. I think also with the US Government getting behind the Infrastructure Bill and putting programs out there to help companies transition has really also helped accelerate this process.

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.
