Greentown Labs Taps Big Energy in Texas

What do Somerville, Massachusetts, and Houston, Texas, have in common? The catalytic energy of Greentown Labs. 

Twelve years ago in a dark Cambridge warehouse, a motley crew of entrepreneurs were busy with the business of changing the world, focused on climate tech as the solution to a growing list of challenges. For the four founders, the list included more immediate challenges like the fact that they were quickly outgrowing their scrappy setup. Enter CEO Emily Reichert, Greentown Labs’ first official employee. She corralled the all-star team and their 25 new startups and raised $1.5 million in six months to move from their basement to a shining 33,000-square-foot facility in Somerville that would welcome 40 companies in no time at all. Soon after, they would need even more room — 100,000 square feet of world-class research space to be exact, now home to over 100 companies. Reichert credits Somerville Mayor Joe Curtatone for recognizing early on “the opportunity for the future of his city being about innovation, being about cleantech. To this day he’s a wonderful partner.”

Meanwhile in Texas, another mayor was looking to innovate. Sylvester Turner of Houston is the co-chair of Climate Mayors, a bipartisan network of 450 U.S. mayors making moves for the climate and he’s not just talking the talk. While Texas is still big on oil and gas, Houston has quietly claimed a leading role in the cleantech and renewable energy sectors. With more than 130 solar and wind companies calling it home, the city is now powered by 100 percent renewables. In April 2020, Mayor Turner unveiled the “science-based, community-driven Houston Climate Action Plan” to reduce greenhouse gas emissions with a goal of carbon neutrality by 2050. As explained on “After three 500-year floods in as many years culminating with the largest rain event in North American history, climate change is an unprecedented challenge for Houston. Sustainability and resiliency go hand-in-hand and this plan is essential to the health and economic vitality of Houston’s future. The time for bold action is now.” 

And that’s why North America’s largest climate tech startup incubator is launching their second location right smack in the middle of Houston’s energy field. As part of the incubator’s announcement, Reichert said: “Houston—the energy capital of the world—is the best place to broaden our impact and help accelerate the energy transition through cleantech entrepreneurship, in partnership with the nation’s fourth-largest city and the world-leading energy organizations headquartered there. We believe the engineering strength, talent, and assets of the energy industry in Houston can and must be redeployed toward a decarbonized future. Climate change cannot be solved from the coasts—we need all hands on deck at this time. Houston has the opportunity to be the energy transition capital of the world and we believe bringing Greentown Labs to Houston will accelerate the shift in this direction.”

Greentown Labs wants to get us to think about how we engage with and use energy. They want to explore better ways to build our buildings, get from place to place, grow and package our food, and preserve our natural resources like clean drinking water. And so far, it’s working. The Greentown Labs site boasts $1.56 billion in economic impact, 280+ companies incubated, an 88% startup survival rate, $850 million raised in funding, and 6,500 jobs created. Those are some impressive numbers. And now, with Greentown Labs Houston, they’re going exponential. “What I’m most excited about is bringing folks that are working in all aspects of energy along to be part of the energy transition” Reichert explained, “to really figure out what’s possible and engage them in this process.”

Months out from a spring launch, the Houston community is already engaged. Today, Greentown Labs announced 16 inaugural startups. Members of Greentown Labs pay monthly fees in exchange for access to lab and office space, as well as a myriad of collaborative opportunities within the community. Greentown relies heavily on partnerships and grants to keep membership fees low for their burgeoning entrepreneurs. And they don’t require equity in exchange. Reichert told us what drew her to Greentown Labs back in 2013 was “that vibe, that community, that spirit of supporting each other in what is a really tough thing to do. It’s tough to be an entrepreneur, but it’s super tough to be an entrepreneur solving climate and cleantech problems.” Nobody would disagree that the startup life is tough, but it’s one that Reichert and the whole Greentown community consider rich with opportunity. That opportunity is evident in the powerhouse partners lined up to support Greentown Houston, including Chevron, Shell, BHP, Microsoft, and Direct Energy, among others.

People matter; the location is everything — two truths not lost on Greentown Labs. They’ve secured a 40,000-square-foot spot in Houston’s Innovation District, with easy access to downtown to connect with potential investors, corporations, and civic leaders, in close proximity to local universities doing their own climate tech research including Rice University, the University of Houston, and Houston Community College. And last but certainly not least, it’s an easy walk to the Houston METRORail or you could just ride your bike on a new protected bikeway right up to the front door. 

Living the dream is living the mission at Greentown Labs, and Reichert invites everyone to consider: “What does energy look like going forward?” This is a global problem that will require a global-scale solution. And what better place to go big or go home, than Texas? “We’re excited about engaging a community, and a broader ecosystem of folks that are working in the energy industry, broadly defined — both the renewable energy industry and the more traditional incumbent industries. And all of us need to be part of what, in the Houston area, we call the energy transition.”

Greentown Houston Inaugural Startups

Greentown Houston will have room for 50 companies and 200-300 employees. Interested startups may apply on their site.

  • Applied Bioplastics produces affordable polymers with properties that are equal to or better than those of traditional petrochemical plastics. These polymers use significant plant matter, which absorbs CO2 and avoids the CO2 emissions of petrochemical plastics. Applied Bioplastics’ thermoplastic replacement displaces 30 percent of the petrochemical content, resulting in a carbon-negative footprint.
  • Black Mountain Metals is a global battery metals mining company, specifically focused on sustainable nickel and copper mining for lithium-ion battery cathodes.
  • Carbon Free Technologies provides the world’s only “plug-in-the-wall” home battery system/appliance, which stores electricity when electricity rates are low, so the electricity can be used later to avoid paying higher rates. This new system requires no installation, no permits, and no utility approvals.
  • ClearValue deploys zero-net-carbon, sustainable, renewable, and resilient electrical generation and transportation power systems via combustion of in situ, sunlight-powered, bio-chemically formed, pure hydrogen and oxygen.
