Why Energy Storage? Roadmap Rationale
ICEF concept pursues long term net-zero emissions through innovation. To assist
the transformation, energy storage will work as one of important enabling
technologies.
Energy storage technology can enhance energy system flexibility. It fills the gap
between electricity and/or heat supply-demand in terms of time and/or space.
Benefits of storage technologies
Improving resource use efficiency
Integrating high level variable renewable resources
End-use sector electrification especially in transport
Supporting production of energy where it is consumed
Increasing energy access
Improving electricity grid stability, flexibility, reliability, and resilience.
Low-carbon supply
Energy storage in demand Low-carbon demand
Energy storage in supply Transformation toward net-
zero emissions

Energy Storage Demand Current Power Storage Capacity
159GW of energy storage are deployed in 2015. 96% is pumped storage hydropower.
For stationary energy storage, it is estimated that 1,365GW are deployed in 2060 in 2DS scenario, while 1,589GW in B2DS scenario.
For mobility battery, it is estimated that about 28TWh are deployed in 2060 in 2DS scenario, while about 62TWh in B2DS scenario.
