Vehicle-to-grid (V2G) storage may be all that grids need for stability as renewables increase, according to a speaker at the upcoming Energy Storage World Forum, on May 8 to 12.

“With V2G technology we can provide grid stabilisation services without any need for additional storage reserves, but by simply aggregating electric vehicle batteries,” said Ernesto Ciorra, Enel’s head of innovation and sustainability.

“With the current technology that we are already improving, for a country like Denmark to provide stabilisation services we need about 40 electric vehicles, while in Germany and UK the minimum number is about 100.”

Ciorra told Energy Storage Report that if all the 18,000 Nissan electric vehicles in the UK were connected to the electricity network, they would generate an output equivalent to that of a 180MW power plant.

“If that were to be scaled up in a future where all vehicles on UK roads were electric, V2G technology could generate a virtual power plant of up to 370GW,” he said.
