New Hydrogen Engine Design Unveiled To Overcome Reliance On Fuel Cells

The title of this post, is the same as that of this article on Hydrogen Fuel News.

The article describes an innovative hydrogen-powered engine developed  by an Israeli company called Aquarius Engines.

This is the sub-heading, that gives a little bit more information.

Aquarius Engines has developed a small 10kg emission-free unit operating entirely on H2.

It appears to be based on the company’s patented single-piston-linear-engine.

This page on the Aquarius web site describes the combustion technology in a short video.

Wikipedia also has an entry on the free-piston engine.

The power output of the Aquarius engine is not given.


I have a hunch, that Aquarius Engines might be on to something!

Light weight is so important in many applications.
