Having very large quantities of storage will be essential to counter the supply shortages caused by dependence on wind and solar power. Vehicle-to-grid (V2G) storage is seen by the National Grid as capable of providing more storage than any of the alternative storage technologies.
It is relatively new technology, and its success depends on a number of factors:
- the rollout of battery electric vehicles (BEVs)
- implementation of the required supporting infrastructure
- adoption and use of V2G by BEV owners.
Given that the rollout of BEVs is currently behind schedule and there is no live use of V2G so far, we rate it as Amber.
Note that the National Grid's Five Year Forecast figures that are shown in the chart are based on the date for the ban of sale of new ICE cars which was in force when FES 2020 was published.
