Three Houston energy tech innovators sought to quantify Houston's growth as an energy tech ecosystem, and, after 200 survey respondents and dozens of interviews, they've created six calls to action for the city.

Taylor Chapman, Gabe Malek, and Deanna Zhang created the Texas Climate Tech Collective to issue the Houston's Climate Tech Ecosystem 2023 report. The trio revealed some of its key takeaways at Greentown Houston's Climatetech Summit last month.

"We wanted to understand how the city has evolved," Malek, who's also chief of staff at Fervo Energy, said at the event. "We went into this project with a shared belief that Houston has unique characteristics that set it apart from the other cities thinking about climate, and if we could really lean into those characteristics, develop them, and amplify them, we could help grow the ecosystem in Houston and build climate solutions ... to accelerate the energy transition."

The full report, which is available online, highlighted six key takeaways paired with six action items.

1. "Houston has a perception problem."

Houston is known as a leader in the energy industry, which positions it well in a lot of ways, but in other ways, as Zhang points out, Houston might be being left out.

"People in this community like to talk about energy because we are the energy capital of the world, so we use a lot of energy-centric terms," she says, using "energy transition" as an example. "We don't use the word climate enough."

It might just be semantics, but it could be a reason the city isn't as regarded as a climatetech leader.

"If other ecosystems are using 'climate' and 'climatetech,' we need to be using these terms," she continues. "It's like SEO but for the ecosystem."

2. "Houston needs more risk capital, especially at the earlier stages." 

Money is a huge factor, which comes as no surprise. While the city has a lot of corporations and private equity here, as Zhang explains, there seems to be room for improvement for early-stage resources.

"If you're a founder raising pre-seed, seed, or even series A, often times you have to go outside of Houston to meet those investors," she says.

According to the report, about half of survey respondents chose "access to venture capital" as one of the biggest challenges facing the ecosystem.

3. "Houston’s startup scene has improved radically."

The report found that 80 percent of responders agreed to the statement: “the ecosystem has improved dramatically over the last 5 years.” Meanwhile, 75 percent of respondents agreed that “Houston is more innovative than outsiders perceive it to be."

So what's holding the city back? According to the collective, "Shameless self-promotion of ecosystem accomplishments."

"We need to be shouting from the rooftops what is happening in this city. It's really a PR game," Zhang says.

4. "Houston’s energy resources and infrastructure have massive potential to create change, but are underutilized by the climate ecosystem."

The collective and survey respondents acknowledge that Houston has a lot of infrastructure already in place, but the call to action is for coordination of these resources.

"Greentown, Ion, Halliburton Labs, HETI — the list goes on and on, but people don't know where to start," Chapman says.

The report says the city's resources are "woefully undertapped" and "29 percent of respondents highlighted partnerships, coordination of existing assets, and Houston’s own future investments in infrastructure as potential accelerants to growth."

5. "Houston’s strong workforce and human capital are one of its greatest strengths – and it should be investing in transitioning that workforce to new opportunities."

Cultivating the workforce for the energy transition needs to be a major priority, according to the collective. The city has a talented workforce for engineering, technical, and project management talent.

"How do we reach and transition this workforce?" Chapman asks. "It's a huge opportunity and critical for Houston to ensure that its economic development continues to grow."

6. "Houston knows how to build...but needs to put expertise that towards climate innovation."

Houston as a major, sprawling city needs to continue to become "greener" in every way. While Chapman praises the city has done with its Climate Action Plan, Houston still lags other major cities like Los Angeles and New York in this way, per the report. Fourteen percent of respondents cited better climate-friendly infrastructure as a priority issue.

Chapman urged the audience to get involved locally to move the needle on more green initiatives for the city.

Greentown Labs names first head of philanthropy

new hire

Greentown Labs has named its first-ever head of philanthropy in an "all hands on deck" move to advance philanthropic support for climatetech ventures.

Stacey Harris will join the clean energy incubator and brings more than 15 years of experience to the role, having led major partnerships at organizations like Make-A-Wish International, Movember, Net Impact and the Greater Phoenix Economic Council, according to a release from Greentown.

Harris will be based out of Greentown's Boston-area incubator but will support both its Texas and Massachusetts locations. Greentown maintains headquarters in Houston and Somerville, Massachusetts.

“Stacey brings national reach, local roots, and the entrepreneurial spirit we need,” Georgina Campbell Flatter, CEO of Greentown, said in the release. “She understands that philanthropy isn’t just about raising funds—it’s about building a movement, sustaining an ecosystem, and accelerating change together.”

In her new role, Harris will be tasked with designing and leading a philanthropic strategy that aligns with Greentown's corporate partnerships.

The incubator said in the release that Harris's hire is coming at a "pivotal moment," and the organization is "calling for all hands on deck" to support the clean energy space. "This includes inspiring states and local governments to lean in, individuals and family offices to step up, foundations to mobilize resources, and industry to invest boldly," the release states.

"Philanthropy has the unique power to accelerate innovation where it matters most—by backing the people and ideas that can change the world,” Harris added in the release. “At Greentown, I see an incredible opportunity to partner with local communities in Massachusetts and Texas, while also mobilizing catalytic funds that fuel entrepreneurs globally. I’m energized to work across donors, foundations, and industry to ensure these founders have what they need to go further, faster—together.”

Harris is the latest in a series of new hires for Greentown.

Lawson Gow, founder of The Cannon co-working space and former managing partner at Helium Capital, was named Greentown's Head of Houston in July. Flatter was also named as the organization's new CEO in February, after Naheed Malik was named its new CFO in January.
