Teragen Energy Raises $6M in Pre-Seed Round

Teragen Energy, a Southborough, Massachusetts-based clean energy startup, has raised $6 million in pre-seed funding to develop its solid oxide fuel cell power systems.

The round was co-led by BEVC and Energy Capital Ventures, with participation from AP Ventures, AIC Ventures, Massachusetts Clean Energy Center (MassCEC), and UntroD Capital Asia.

Teragen Energy develops modular, fuel-flexible solid oxide fuel cell systems designed to provide reliable onsite power for data centers, industrial facilities, and utilities.

The company’s technology was co-invented at Berkeley Lab and is designed to deliver high efficiency, power density, and responsiveness while producing near-zero local pollutants. The systems can also be integrated with carbon capture or energy storage.

“Today’s society runs on electricity, and tomorrow’s even more so,” said Dr. Ruofan Wang, CEO of Teragen Energy. “By redefining what a fuel cell can do, Teragen Energy can drive down both electricity costs and emissions without sacrificing reliability.”

“Teragen Energy’s next-generation fuel cell technology holds promise to play a key role in addressing the energy trilemma, offering a lower carbon, reliable, dynamic power solution with compelling economics,” said Joshua James, Investor at BEVC.

Victor Pascucci III, Managing General Partner at Energy Capital Ventures® said, “The natural gas industry is the backbone of the energy expansion. The industry needs more modular and scalable technology to provide the clean, safe, reliable, cost-effective energy of the future. Teragen’s next generation fuel cells are vital to the future of energy and the energy expansion.”

Teragen will use the new funding to expand its testing and manufacturing infrastructure, scale its fuel cell technology, hire additional engineers, and advance its first commercial pilot projects with data center, industrial, and utility partners.

Founded by CEO Dr. Ruofan Wang, CTO Joshua Persky, and CCO Emerson Reiter, Teragen aims to provide scalable onsite power as electricity demand continues to grow across AI, advanced manufacturing, and other energy-intensive industries.
