National Grid expects more ESS with longer durations for UK’s almighty low carbon challenge

In the UK’s path to net-zero carbon energy, every scenario modelled in National Grid’s ‘Future Energy Scenarios 2019’ sees electricity storage capacity and duration rise to help integrate variable renewable generation.

Sister-site Current± has just taken an extensive look at the energy system operator’s (ESO) latest outline of potential outcomes for the next 30 years of Britain’s energy, in the wake of UK prime minister Theresa May setting in motion a target of reaching net-zero by 2050.

As well as a notable expectation of the role vehicle-to-grid (V2G) could play, “electricity storage capacity as a whole increases in all four scenarios, with a particular need for larger, longer duration storage, due to increases in intermittent renewables,” reporter Alice Grundy writes.

“Growth is supported through the continued fall in battery costs and developments in other storage technologies,” with National Grid also making “the assumption in all four scenarios that storage projects will need multiple income streams to be commercially viable, suggesting that price arbitrage, balancing and ancillary services and providing services to network operators could be potential revenues.”

Read Current±’s in-depth look at National Grid Future Energy Scenarios 2019 and learn why one commentator believes there is “no part of our economy that escapes the need to decarbonise rapidly”.
