Energy storage

Several major policies and projects announced in the past year are expected to boost growth in global energy storage deployment.

Key findings

Annual energy storage additions by country, 2015-2020


Battery storage capacity additions in 2020 rose up 50% after 2019

Battery storage capacity additions in 2020 rose to a record-high 5 GW, up 50% after a mediocre 2019, when installations failed to rise for the first time in a decade. China and the United States each registered gigawatt-scale additions. Utility-scale installations continue to dominate the market, accounting for around two-thirds of total added capacity. Although new policies and projects in key markets are set to accelerate growth, an even faster rise is needed to align with the Net Zero Emissions by 2050 Scenario, which sees nearly 600 GW of battery storage capacity installed by 2030.
Our work

The mission of the Energy Storage TCP is to facilitate research, development, implementation and integration of energy storage technologies to optimise the energy efficiency of all kinds of energy systems and enable the increasing use of renewable energy. Storage technologies are a central component in energy-efficient and sustainable energy systems. Energy storage is a cross-cutting issue that relies on expert knowledge of many disciplines. The Energy Storage TCP fosters widespread experience, synergies and cross-disciplinary co-ordination of working plans and research goals.
