ensure the linear generator’s performance, emissions, efficiency, and noise levels are suitable for the needs of the local power grid both today and into the future.
The Mainspring linear generator is highly fuel-flexible, able to change fuel sources in real time while in operation, with the range of fuel sources including biogas and natural gas, as well as hydrogen, or any blends of these. Further, the hydrogen does not need to be high purity. This fuel-flexibility “ensures that the linear generator capacity can stay online when needed most,” says NGV.
Mainspring Energy, a Stanford spin-out, began commercial shipments of its linear generators in 2020 and says that to date it “has hundreds of megawatts in field operations and advanced development for leading Fortune 500 companies, data centre developers, and utilities.”
Verdagy project
Another project envisaging running Mainspring linear generators on hydrogen is a collaboration with electrolysis company Verdagy. The plan is to establish a hydrogen-powered linear generator demonstration installation at Verdagy’s Moss Landing (California) site, where it operates a hydrogen production plant and R&D complex.
Verdagy’s Moss Landing hydrogen production facility 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 will supply Mainspring with “constantly available, low-cost hydrogen as a fuel for power generation,” says Verdagy. It will also provide

Verdagy with onsite offtake for its hydrogen and electricity to support electrolyser operation. “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,” the company says.
Operations were expected to begin in summer 2025 at Moss Landing. “Verdagy and Mainspring Energy are demonstrating how we can improve energy resiliency for the electrical grid, datacentres and other applications,” says Marty Neese, CEO of Verdagy. “This collaboration with Mainspring Energy is a compelling model for clean, flexible, on-site power solutions.”
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 co-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 aims to demonstrate 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,” suggests Verdagy.
Verdagy says its Dynamic AWE electrolysers achieve the lowest levelised cost of hydrogen (LCOH), highest asset utilisation (by integrating seamlessly with intermittent energy sources), and “market-leading efficiencies.”
Green H2
From the cradle of ancient trade routes to the forefront of tomorrow’s energy economy, the Middle East is reclaiming its historic role — this time as the world’s dominant green hydrogen powerhouse. The Middle East has a long history as a leading global player, first as a vital hub of ancient trade, and more recently as a major oil exporter and global energy centre for over a century. Iran’s first major oil discovery in 1908,

followed by a post-World War II production boom, transformed the region into an energy powerhouse — and reshaped global politics for decades.
But times are changing. Countries like Saudi Arabia, the United Arab Emirates (UAE), Oman and Qatar are redefining their long-term energy and economic futures and positioning themselves as up-and-coming leaders in an envisaged future green hydrogen
economy. We’re seeing a shift away from fossil fuel dependency, and towards diversified, sustainable exports that better support global decarbonisation goals.
Green hydrogen is seen as potentially a key future export in the energy transition. Its versatility spans electricity, heating, transport and industry, and it offers a decarbonisation pathway for hard-to-electrify sectors like steel and logistics.
