Verdagy to Supply Hydrogen to Mainspring Energy to Power Linear Generators

MOSS LANDING, Calif., May 28, 2025 /PRNewswire/ -- Verdagy, a leading clean hydrogen electrolysis company, has partnered with Mainspring Energy, Inc. to establish a hydrogen-powered linear generator installation in Moss Landing, California. Verdagy's Moss landing plant has been in operation for four years with more than 20,000 hours of operation with commercial cells and over 200 tons of hydrogen produced. The fully automated, 24/7 plant provides Mainspring constantly available, low-cost hydrogen as a fuel for power generation.

This collaboration establishes a ready hydrogen fuel source for Mainspring's fuel-flexible linear generators and provides Verdagy with onsite offtake for its hydrogen and electricity to support its electrolyzers operation. The two companies expect to begin operations by summer 2025.

"Verdagy and Mainspring Energy are demonstrating how we can improve energy resiliency for the electrical grid, datacenters and other applications," said Marty Neese, CEO of Verdagy. "This collaboration with Mainspring Energy is a compelling model for clean, flexible, on-site power solutions."

Building on its expertise in producing clean hydrogen at scale, Verdagy is now reducing operational costs by converting hydrogen into power and cycling it back into the facility.

"This agreement presents an excellent opportunity for Mainspring to showcase our linear generator's capabilities operating on hydrogen and for Verdagy to demonstrate its high resiliency industrial grade production operation," said Shannon Miller, Mainspring CEO and Founder. "We're pleased to partner with Verdagy to highlight the significant potential of hydrogen in power generation."

By powering Mainspring's Linear Generators with hydrogen produced on-site, the installation demonstrates how low-carbon energy can be deployed at the point of use – critical for enhancing resiliency in grid constrained and mission-critical environments. This co-located model for hydrogen consumption to generate power is crucial as grid constraints grow.
