The technology is based on a high-temperature process causing a light metal wire (e.g., aluminum or magnesium) to react with water, producing a hydrogen/steam stream. The hydrogen/steam mixture entering the engine is oxidized by air, thereby using both the chemical energy stored in the hydrogen and the thermal energy produced by the reaction.

The spent product from Engineuity’s process is a light metal oxide that is eventually separated and sent back to the factory for electrochemical recycling.
