Powering Up Long Island’s Power Grid with World’s First 100 Percent H2-Fueled Commercial Linear Generator

The world’s first commercially-deployed, 100% hydrogen-fueled linear generator, (LGen), is coming to Long Island. In partnership with National Grid Ventures (NGV), the New York State Energy Research and Development Authority (NYSERDA), the Long Island Power Authority (LIPA), Stony Brook University and Mainspring Energy, the 250kW LGen is expected to be installed at NGV’s Northport power plant in September 2026.

The project represents an important step in meeting New York’s clean energy mandates by demonstrating a Dispatchable Emission-Free Resources (DEFR) technology solution that can be deployed when needed to meet peak energy needs and will also add much-needed fuel flexibility, resilience and reliability to the region’s power grid.

Associate Professor Dimitris Assanis from the Mechanical Engineering department at Stony Brook University and his team at the Advanced Combustion & Energy Systems (ACES) Laboratory will independently validate the project by developing key data acquisition, instrumentation and post-processing analysis routines to track and monitor key performance and emission metrics.

“What’s really exciting about this project,” Professor Assanis said, “is that we are taking next-generation energy-conversion technology beyond the classroom and the lab and bringing it into the real world. If we get this right,” Assanis added, “we will have a new tool to tackle the grand energy challenges we are facing”
