Electricity storage is currently an economic solution of-grid in solar home systems and mini-grids where it can also increase the fraction of renewable energy in the system to as high as 100% (IRENA, 2016c). The same applies in the case of islands or other isolated grids that are reliant on diesel-fired electricity (IRENA, 2016a; IRENA, 2016d).
More directly, electricity storage makes possible a transport sector dominated by electric vehicles (EVs), enables efective, 24-hour of-grid solar home systems and supports 100% renewable mini-grids. As variable renewables grow to substantial levels, electricity systems will require greater flexibility.
As variable renewables grow to substantial levels, electricity systems will require greater flexibility. At very high shares of VRE, electricity will need to be stored over days, weeks or months. By providing these essential services, electricity storage can drive serious electricity decarbonisation and help transform the whole energy sector.
In transport, the viability of battery electricity storage in electric vehicles is improving rapidly. Batteries in solar home systems and of-grid mini-grids, meanwhile, are decarbonising systems that were heavily reliant on diesel fuel, while also providing clear socio-economic benefits.
