The way Doug Lee looks at it, there are two areas within the energy transition attracting capital. With his new venture studio, he hopes to target an often overlooked area that's critical for driving forward net-zero goals.

Lee describes investment activity taking place in the digital and software world — early stage technology that's looking to make the industry smarter. But, on the other end of the spectrum, investment activity can be found on massive infrastructure projects.

While both areas need funding, Lee has started his new venture studio, Flathead Forge, to target early-stage hardtech technologies.

“We are really getting at the early stage companies that are trying to develop technologies at the intersection of legacy industries that we believe can become more sustainable and the energy transition — where we are going. It’s not an ‘if’ or ‘or’ — we believe these things intersect,” he tells EnergyCapital.

Specifically, Lee's expertise is within the water and industrial gas space. For around 15 years, he's made investments in this area, which he describes as crucial to the energy transition.

“Almost every energy transition technology that you can point to has some critical dependency on water or gas,” he says. “We believe that if we don’t solve for those things, the other projects won’t survive.”

Lee, and his brother, Dave, are evolving their family office to adopt a venture studio model. They also sold off Azoto Energy, a Canadian oilfield nitrogen cryogenic services business, in December.

“We ourselves are going through a transition like our energy is going through a transition,” he says. “We are transitioning into a single family office into a venture studio. By doing so, we want to focus all of our access and resources into this focus.”

At this point, Flathead Forge has seven portfolio companies and around 15 corporations they are working with to identify their needs and potential opportunities. Lee says he's gearing up to secure a $100 million fund.

Flathead also has 40 advisers and mentors, which Lee calls sherpas — a nod to the Flathead Valley region in Montana, which inspired the firm's name.

“We’re going to help you carry up, we’re going to tie ourselves to the same rope as you, and if you fall off the mountain, we’re falling off with you,” Lee says of his hands-on approach, which he says sets Flathead apart from other studios.

Another thing that's differentiating Flathead Forge from its competition — it's dedication to giving back.

“We’ve set aside a quarter of our carried interest for scholarships and grants,” Lee says.

The funds will go to scholarships for future engineers interested in the energy transition, as well as grants for researchers studying high-potential technologies.

“We’re putting our own money where our mouth is,” Lee says of his thesis for Flathead Forge.

Houston clean energy leader to receive posthumous Trailblazer Legacy Award

lasting legacy

Every year, the Houston Innovation Awards, presented by EnergyCapital's sister site InnovationMap, honor one Houstonian with the Trailblazer Award, whose impact is felt throughout the city's innovation and business ecosystem.

This year, the Trailblazer Legacy Award will be given posthumously to Don Kendall Jr., who died in September while on a trip to the Republic of the Congo with the Jane Goodall Institute, one of the many organizations he was deeply involved with.

Kendall's obituary puts it simply: "Don’s truest passions were conservation and his family." Many saw those passions play out in his career, particularly in the role he played in shaping Houston's clean energy sector.

Kendall served as general partner of New Climate Ventures, a Houston-based early-stage venture capital firm that invests in next-gen energy, materials and fuel technologies and startups. The firm's portfolio includes Houston-based clean energy companies like Solidec, Syzygy Plasmonics and Rheom Materials.

Kendall was also founding managing director and CEO of Kenmont Capital LP. He ran a $500 million distressed debt and credit-based hedge fund focused on the energy, power and transportation sectors and one of the top-performing private equity funds under the Kenmont umbrella.

He served on the board of Talos Energy, American Midstream Partners, Syzygy Plasmonics, Tangent Energy, Stream Energy and others. Notably, he served as Chair of the Special Committee of the SolarCity board during its acquisition by Tesla in 2016. According to his obituary, Kendall negotiated with "Elon Musk in the middle of the night on a rickety pier in Indonesia after eluding a poisonous snake."

Outside of the clean energy space, Kendall also served on the boards of the Jane Goodall Institute, Earthwatch International and Ecological Defense Group. He also served as vice chair of the Houston Zoo Inc. and chair of its Conservation Committee.

Kendall was selected by our esteemed panel of judges to receive the 2026 Trailblazer Legacy Award. The panel includes carbon removal entrepreneur and CEO of Houston-based Mars Materials Aaron Fitzgerald.

Fitzgerald shares the profound impact Kendall had on his career and those of many others.

"Honoring Don with the Trailblazer Legacy Award is a fitting tribute to a leader whose impact spanned civic work with the Houston Zoo, wildlife conservation, and the growth of our startup ecosystem," Fitzgerald says. "He paired a keen eye for potential with the relentless drive to unlock it. For Mars Materials, his early backing carried us through a critical valley when we needed belief the most, and his presence as a personal mentor is profoundly missed."

Don was an avid traveler, cyclist and collector. He is survived by his wife of 50 years, Diane S. Kendall. A celebration of life will be held early in 2027.

Katy’s TerraFlow acquires Houston battery tech startup FlowCellutions

m&a activity

Katy-based TerraFlow Energy, an energy storage and infrastructure company, has acquired Houston-based battery technology startup FlowCellutions. Financial terms weren’t disclosed.

FlowCellutions still operates under its established name, but with the tagline “A TerraFlow Energy Company.” Becca Segel, founder and CEO of FlowCellutions, now runs the business as its president.

FlowCellutions specializes in electrochemical sensing, diagnostics, analytics, and testing that offer insights into battery chemistry, charging capabilities, and system performance.

“FlowCellutions has always been focused on developing better ways to understand what is happening inside a flow battery and using that information to improve how these systems perform,” Segal said in a press release. “Joining TerraFlow gives us the opportunity to apply that work at a much larger scale while continuing to build the capabilities and expertise that make FlowCellutions unique.”

The FlowCellutions platform supports data centers and other heavy users of power. It’s designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from about seven years to more than 30 years.

Segel founded the company in 2022. A member of Greentown Labs, the company raised more than $2 million in non-dilutive funding and received $1.5 million in National Science Foundation funding earlier this year.

FlowCellutions is one of five finalists in the Energy Transition Business category of InnovationMap’s 2026 Houston Innovation Awards.

“FlowCellutions brings a depth of scientific and technical expertise that fits naturally with where TerraFlow is going,” Jon Parrella, CEO of TerraFlow, said in the release.

“As we move from developing these systems to deploying them at commercial scale, understanding performance at a deeper level matters,” he said. “Bringing FlowCellutions into TerraFlow strengthens that capability and gives both teams more opportunity to advance the technology.”

TerraFlow, founded in 2024, develops long-duration energy storage and power infrastructure for data centers, industrial facilities, utilities and other large power consumers.
