Electric Vehicles Could Be The Grid Storage Solution We’ve Been Dreaming Of

As nation states grapple with the spectre of environmental and economic losses due to climate change, we’ve seen an ever greater push towards renewable energy sources to replace heavier polluters like coal and natural gas. One key drawback of these sources has always been their intermittent availability, spurring interest in energy storage technologies that can operate at the grid level.

With the rise in distributed energy generation with options like home solar power, there’s been similar interest in the idea of distributed home battery storage. However, homeowners can be reluctant to make investments in expensive batteries that take years to pay themselves off in energy savings. But what if they had a giant battery already, just sitting outside in the driveway? Could electric vehicles become a useful source of grid power storage? As it turns out, Ford wants to make their electric trucks double as grid storage batteries for your home.

The Hornsdale Power Reserve And What It Means For Grid Battery Storage

Renewable energy has long been touted as a major requirement in the fight to stave off the world’s growing climate emergency. Governments have been slow to act, but prices continue to come down and the case for renewables grows stronger by the day.

However, renewables have always struggled around the issue of availability. Solar power only works when the sun is shining, and wind generators only when the wind is blowing. The obvious solution is to create some kind of large, grid-connected battery to store excess energy in off-peak periods, and use it to prop up the grid when renewable outputs are low. These days, that’s actually a viable idea, as South Australia proved in 2017.
