On Demand Hydrogen System

Recommended Posts

Hi guys

Had an e-mail today from an ecu remap company recommending an on demand hydrogen system.

Apparently this would increase fuel consumption by at least 20% and enhance performance.

Does anyone have any experience of this? First I've heard of such a thing!

Sorry for the bump but I am very interested in a 20% fuel consumption decrease but skeptical of why this isn't more widely known and utilised by car manufacturers.

Saab did it an age ago. Basically, you have a water reservoir and it's sprayed into the cylinder to lower cylinder temperature. Works in the same way as an intercooled turbo vs a non-intercooled turbo, lower temperature = increased efficiency and power.


Water injection is nothing new. Can be helped further with a little methanol too.
