Australian energy company Lavo is throwing down the gauntlet to Tesla’s Powerwall with a home hydrogen battery storage system that doesn’t conventional batteries at all, New Atlas reports — opting for hydrogen as fuel instead.
It stores some 40 kilowatt-hours worth of energy.
That's three times as much as Tesla's current Powerwall 2. That's enough to run an average home for two days.
