Electric water heaters offer a cheap way to store large amounts of energy, in the form of hot water. A heater with a 300-liter tank can store about as much energy as a second-generation Tesla Powerwall—at a fraction of the cost.
Australians could use household electric water heaters to store as much energy as over 2 million home batteries of that kind. This could eventually save over A$6 billion a year on our energy bills while getting us closer to net-zero carbon emissions.
