Greengrove 2250, New South Wales. Power cut backup for grid-connected homes, with days of stored energy instead of hours.
Greengrove is classed as inner regional. Most homes here are on the main grid, but storms and faults on rural feeder lines still cut power, and the further a line runs the longer a repair can take.
Cheap power splits water into hydrogen. The hydrogen waits in a tank. When the lines go down in Greengrove, a fuel cell turns it back into electricity and water, and the water goes round again.
How it works →Yes, that is what it is designed for. A Greengrove 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.
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.
It is in early development. Pilot installs go to people on the pilot list first, and inner regional New South Wales properties like those around Greengrove are exactly who the pilot is for.
Pilot installs go to people on this list first. Rural homes, farms and remote sites especially. No spam, no payment.
