The company behind the engine claims it addresses the limitations of hydrogen fuel cells

Israel-based Aquarius Engines has unveiled a new hydrogen engine that it claims could reduce global reliance on both hydrogen fuel cells and fossil fuels, according to a press release via PR Newswire.
Weighing just 22 lbs (10 kg), the single-piston linear engine operates solely on hydrogen and consists of only 20 components with one moving part, making it significantly cheaper to produce and maintain compared to traditional engines.
While the company has not released detailed specifications, Aquarius Engines stated that the engine’s lightweight design and unique internal gas exchange method could drastically cut emissions and contribute to reducing the global carbon footprint.

The engine has successfully passed performance tests conducted by Austrian engineering firm AVL-Schrick, confirming its ability to run exclusively on hydrogen.
“Our dream at Aquarius Engines has always been to revolutionize hydrogen technology as the fuel of the future,” said Gal Fridman, Chairman of Aquarius Engines. “Our hydrogen engine, which doesn’t require expensive fuel cells, could offer a cost-effective, green, and sustainable solution for global transportation and remote energy production.”
