Israel-based Aquarius Engines unveiled a new hydrogen engine that it says could do away with the global reliance on hydrogen fuel cells and fossil fuels, the company explained in a press statement via PR Newswire.

The machine, which weighs only 22 lb (10 kg), is a single-piston-linear-engine, that runs exclusively on hydrogen. As it has only 20 components and one moving part, the engine is also much cheaper to produce and maintain than traditional engines.

Though Aquarius Engines has so far released little in the way of specifications for their new engine, the company says the Aquarius Hydrogen Engine's "lightweight design and unique internal-gas-exchange-method would greatly reduce emissions and lower the global carbon footprint."

The company said its new hydrogen engine has successfully passed a test by Austrian engineering firm AVL-Schrick, showing that the model does indeed operate on hydrogen.
