Greentown Labs’ 200+ startups are developing, deploying, and commercializing climatetech solutions to decarbonize the key greenhouse-gas-emitting sectors—agriculture, buildings, electricity, manufacturing, and transportation—and build resilient communities. There’s an incredible amount of work and collaboration needed to get these technologies out of the lab and into the world, from early-stage funding, to pilot projects, to first commercial deployments, and beyond.

Each year, we celebrate some of the most impressive accomplishments our members achieve along this journey. In 2023, Greentown startups installed more than 1,000 EV chargers, secured plans to deliver up to 1 billion gallons of sustainable air fuel, kicked off production at the United States’ first rare-earth refinery, began operations at a geothermal plant in partnership with Google, and so much more. 

Here’s just a sampling of their biggest wins this year.

Partnerships + Deployments

• Form Energy had a banner year deploying its cost-effective, multi-day energy-storage systems, partnering with the State of West Virginia to build its first iron-air battery manufacturing facility in the city of Weirton; winning a $12M grant from the New York State Energy Research and Development Authority to roll out a 10 megawatt/1000 megawatt-hour iron-air-battery system in New York State; partnering with Georgia Power to deploy a 15 megawatt/1500 megawatt-hour iron-air-battery system in Georgia; and deploying its technology at two of Xcel Energy’s retiring coal plant sites.
• Cemvita will provide up to 1 billion gallons of sustainable air fuel to Greentown partner United Airlines and opened a pilot plant in Houston to produce eCO2 oil, a soybean oil replacement made from converted carbon emissions.
• Fervo Energy and Google’s next-generation, 3.5-MW geothermal plant, called Project Red, began supplying carbon-free electricity in Las Vegas.
• Via Separations is collaborating with International Paper to deploy its first commercial-scale filtration system.
• SWTCH installed 929 Level 2 EV chargers at apartment buildings across Canada; collaborated with Plugin Stations Online to deploy 100 public EV chargers throughout New York State; and partnered with AutoGrid to integrate 250 EV chargers in multi-tenant properties into an active-demand-response program with a Canadian utility.
• Enviro Power Technologies’ clean-energy-producing hot water system was installed in a 74-unit residential complex in New York City.
• Phoenix Tailings began production at the United States’ first rare-earth refinery using its zero-waste, zero-emission technology.
• Medley Thermal is deploying its electric boiler system at Jay Peak Resort in “one of the largest standalone carbon-reduction projects in Vermont’s history.”

Funding

• Ohmium, a green hydrogen company, raised a $250M Series C for its proton exchange membrane (PEM) electrolyzer technology.
• Amogy raised $150M in Series B funding for its emission-free, energy-dense, ammonia-power solutions. Greentown partners Mitsubishi Corporation and Mitsubishi Heavy Industries joined the Series B-2.
• American Battery Technology Company received two contracts from the U.S. Department of Energy (DOE): a $57M contract for its first-of-kind, commercial-scale, lithium-hydroxide-manufacturing facility in Tonopah, NV, and a $20M contract to advance next-generation battery-recycling technologies. The startup also secured up to $50M in debt financing.
• Energy Dome raised a €55M Series B to help scale its long-duration-energy-storage technology.
• Peak Power, a provider of energy-optimization software and services, raised a $35M round led by Greenbacker Capital Management. It also secured $200M to deploy and finance energy-storage projects for commercial and industrial facilities.
• Ambient Fuels, a developer of green hydrogen projects, received an investment from Generate Capital and an agreement from the company to fund up to $250M of green-hydrogen infrastructure. 
• Sublime Systems raised a $40M Series A to advance its groundbreaking manufacturing process for low-carbon cement, with Greentown partner Siam Cement Group (SCG) as a lead investor.
• Alloy Enterprises closed a $26M oversubscribed Series A for its novel manufacturing method that’s revolutionizing the making of aluminum parts.
• SmartAC.com raised a $22M Series B to ramp up sales of its HVAC-monitoring system.
• Eden closed a $12M seed funding round—which was upsized and oversubscribed—for its Electrical Reservoir Stimulation technology, which it will deploy across geothermal, geologic hydrogen, and sustainable mining applications.
• Lydian raised $12M in seed funding to decarbonize air travel with power-to-liquid fuels.
• Capture6, a Carbon to Value Initiative Year 3 participant, received an $8M+ grant from the California Energy Commission for advancing water recovery and carbon removal through its use of direct air capture technology that uses saltwater to create a solvent for carbon capture.
