Houston startup rings NYSE closing bell

A Houston company got to take the national stage by ringing the closing bell at the New York Stock Exchange, and for Katie Mehnert, founder of ALLY Energy, it was a chance to reflect on the progress the industry as a whole has progressed.

"As I stood on the platform at the world’s largest stock exchange to ring the closing bell, surrounded by 130 people from across the energy industry, I saw it clearly: how the private sector will play a major role in getting us to an era of net zero," Mehnert writes in her guest column. Read the full piece here.

Deadline not to miss: ACCEL

Advancing Climatetech and Clean Energy Leaders Program, or ACCEL, has opened applications for it's second cohort. The program — from Greentown Labs and Browning the Green Space — provides access to funding, networking connections, incubation space, mentorship, resources, and opportunities for energy tech founders of color for a year.

“ACCEL is one of the most impactful, meaningful programs we’ve run to date,” Greentown Labs CEO and President Kevin Knobloch says in a news release. “We are eager to expand upon the great success and momentum of year one, and to welcome another incredible cohort of BIPOC-led startups that are developing much-needed climatetech solutions. We’re equally committed to helping these companies accelerate and deploy their solutions, while also helping to build a more diverse, inclusive climatetech workforce—ACCEL sits at the nexus of those two critical efforts.” Read more about the program.

Founder on ringing the NYSE bell and shining a spotlight on the future of energy in Houston

guest column

As I stood on the platform at the world’s largest stock exchange to ring the closing bell, surrounded by 130 people from across the energy industry, I saw it clearly: how the private sector will play a major role in getting us to an era of net zero. The people who power the energy industry will do the hard work. We’ve already begun. And we’re unafraid of the long journey ahead — something more than 40 of us exemplified that weekend by running a marathon.

The trip to New York City days ago was an exhilarating whirlwind. But it was also something much more: A chance to show the markets, the nation, and the world that Houston is leading the energy transition. (It didn’t hurt that we popped up on Good Morning America.)

From the beginning, the idea behind this pair of events — ringing the bell at the New York Stock Exchange and running the TCS New York City Marathon — was aimed at sending crucial messages. That recognizing climate change and building solutions is an obligation and an opportunity. That the energy industry understands this. That investors have good reason to support climate tech, one of the most exciting and fastest growing sectors. And, last but not least, that people’s perceptions of Houston as being all about oil and gas are simply wrong.

The dozens of us who gathered came from across the country and around the world, But by far, the largest contingent was from right here in Houston. Executives, engineers, entrepreneurs, and other innovators took part. People spearheading projects in every facet of energy, from wind to solar, carbon capture, and other methods of dramatically reducing carbon emissions. All as one team.

Those who traveled from “the energy capital” knew how important it was to highlight our Houston pride. As a new report from the Texas Climate Tech Collective points out, the biggest problem in the city’s climate tech ecosystem is its image. “Outsider perceptions of Houston often draw on negative stereotypes,” the report explains. “The number one disadvantage survey respondents chose – even more than access to VC capital – was Houston’s anti-climate reputation outside the state.”

It’s a problem I’ve been trying to combat for years, including through op-eds in national and international media outlets. Fortunately, the idea is starting to get through. Just days ago, the Financial Times reported that Houston claimed the top spot in this year’s FT-Nikkei Investing in America rankings by “moving beyond oil.” Our city, the paper said, “has become a hub for green energy innovation by building on its hydrocarbon past.”

Houston, and Texas a whole, should be immensely proud of this. But the energy industry has a long history of failing to tell its own stories. It’s time to change that. In fact, the recommendations in the collective’s report include “campaigning to improve Houston’s reputation, improving promotion of Houston’s energy transition initiatives and accomplishments, educating politicians and consumers, reversing anti-climate perception.”

Building bridges

All of the challenges we face, including the perception problem, will only be overcome if we work together. So the era of siloes must end. Climate change is an “all hands on deck” situation. This means companies large and small, as well as businesses focusing on all forms of energy, need to develop a “one-team” mentality.

We also need to step up our engagement with public sector entities. A great deal of public sector investment is being poured into renewable energy programs. Since I’ve served as an ambassador to the Department of Energy’s Equity in Energy initiative and a member of the National Petroleum Council, I’ve met many people in government who are eager to cooperate with us to help ensure that the United States leads the way in the energy transition.

The need for building these kinds of bridges is another reason that many of the participants in our Women & Allies in Energy team saw the New York City marathon as such a strong metaphor. It’s known for its bridges. And having run across all of them — and stopped for a quick selfie on the toughest one of all, the Queensboro Bridge — I’m reminded of their importance. I was happy to see that another recommendation in the collective’s report speaks directly to this. It calls for, “Building bridges between public and private, energy corporates and startups, universities and startups, and startups and mentors; seeking partnerships with other ecosystems; improving resources for early stage startups.”

We also need to build bridges among groups of people. More than ever, the industry needs diversity, equity and inclusion. (See my recent piece for Fast Company about why the C-Suite should double down, not shy away from, DEI.) We need to welcome people with all sorts of backgrounds, experiences, and perspectives. The greatest form of capital the energy sector has in building the future is not financial. It’s human capital. And the greatest natural resource we have is not one form of energy. It’s the people whose hard work, creativity, collaboration, and grit will get us to the finish line.

To help make all this happen, I’m calling for Houston to come together on climate change. Capitalizing on the annual Climate Week in New York City, and building on an event the City of Houston organized in 2021, let’s bring all industries and all people together next fall to show that we recognize climate reality, and are ready to take action together.

The next generation

While I did have the chance to lead the delegation at the NYSE closing bell, I did not hold the gavel — at least, not by myself. Instead, I handed it to my 12-year-old daughter, Ally. (Yes, her name is a big part of the inspiration behind our company name, ALLY Energy.)

As leaders in energy, we have to keep our eyes firmly focused on the next generation. This means not only giving them a strong supply of energy and healthier conditions on the planet. It also means giving them future job opportunities.

It’s up to us to build the pipeline for future talent. We need to improve STEAM (science, technology, engineering, arts and math) education. And we need to demonstrate to people who are currently underrepresented in our industry — such as women and members of minority groups — that they have a future in the world’s most exciting industry.

We can do this. We can get out of our bubble, show our Houston pride to the world, and lead the way to “energy 2.0” — an era of plentiful energy supplies and net-zero emissions. After all, dozens of us have returned from New York City with a mission: capitalize on all that momentum, join together as a team, and run the race to net zero.

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.
