Water in. Power out.

Cheap power splits water into hydrogen. The hydrogen waits in a tank. When the lines go down in Rottnest Island, a fuel cell turns it back into electricity and water, and the water goes round again.

Rottnest Island: questions

Can H2OME power a home in Rottnest Island?

Yes, that is what it is designed for. A Rottnest Island home charges the unit from cheap off-peak power, or from wind or micro-hydro where there is no grid, and runs on stored hydrogen when the power goes. 15 kW continuous covers an average home.

How long can it run Rottnest Island through a power cut?

Days rather than hours. A battery handles the first moments of an outage, then the fuel cell runs the house on stored hydrogen, which does not lose charge while it waits.

When will H2OME be available in Western Australia?

It is in early development. Pilot installs go to people on the pilot list first, and remote Western Australia properties like those around Rottnest Island are exactly who the pilot is for.
