WEO Week: Sectoral transitions to new energy industries

Energy storage

Technology costs for battery storage continue to drop quickly, largely owing to the rapid scale-up of battery manufacturing for electric vehicles, stimulating deployment in the power sector.

Annual energy storage deployment, 2013-2019


In 2019, installations of energy storage technologies fell for the first time in a nearly a decade

For the first time in nearly a decade, annual installations of energy storage technologies fell year-on-year in 2019. Grid-scale storage installations dropped 20%, while residential battery installations doubled, consolidating a shift towards behind-the-meter storage. Continued uncertainty in 2018’s key growth market, Korea, and sluggish activity in Europe and the United States underpinned a lacklustre year for storage. Events in 2019 highlighted how fragile growth in these technologies remains, as they continue to depend heavily on policy intervention through direct support or market creation. Storage needs to return to double-digit growth figures to stay on track with the SDS pathway.
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.
