A global natural gas, LNG, hydrogen, low-carbon solutions, and climate technology convention is coming to Houston next month — but only one Houston startup is geared up for the event's new startup competition.

Gastech invited 20 promising companies for its inaugural Gastech Start-Up Competition, and 11 companies have signed on to participate so far. Houston-based Syzygy Plasmonics, which created and is scaling a sustainable photocatalytic reactor, is currently the only local company among the participants.

“Gastech's focus on creating a low-carbon, affordable energy future aligns perfectly with Syzygy's drive to produce low-carbon, low-cost hydrogen, liquid fuels, and syngas," Syzygy Plasmonics CEO Trevor Best says. "We can't wait to represent Houston as the only startup from the area to be included among the 11 finalists in the Gastech Climatetech Global Entrepreneur Competition.”

It's the first year Gastech, which was announced to be returning to Houston last year, is hosting the competition, which invited startups from the Gastech Hydrogen and Climatetech & AI hubs. The program will allow the participants to promote their projects, benchmark in a competitive setting, and receive critical feedback from experts.

The selected companies are innovating scalable solutions across technologies in climatetech, alternative fuels, industrial decarbonization, AI, hydrogen, and more. Each company will have five minutes to pitch and three minutes of feedback. The winner receives the Gastech 2024 Leading Start-up Trophy.

“We were very impressed by the ability of Syzygy to provide deep decarbonization technology which hit the mark on each of the requirements above – we hadn’t seen it before at Gastech and there is real potential to deliver at scale,” Simon Ford, vice president at Gastech, says.

The other selected and confirmed companies are:

  • General Galactic
  • Element One
  • Stars Technology
  • Modcon System
  • Fluid-7
  • Divigas
  • Gusty.ai
  • Omega Black
  • Kayrros
  • Mitis

The competition is in partnership with Houston Energy Transition Initiative and will take place beginning at 1:30 pm on Wednesday, September 18. Networking will follow the competition. Judges include Jane Stricker of the Houston Energy Transition Initiative, Mahdi Aladel and/or Bruce Niven of Aramco Ventures, and Daniel Palmer of Climate Investment.

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.
