The International Energy Agency has published Batteries and Secure Energy Transitions, a World Energy Outlook Special Report.

Due to their versatility, batteries can serve both utility-scale projects and behind-the-meter storage for households and businesses as well as providing access to electricity in decentralised solutions such as mini-grids and solar home systems. Moreover, steadily decreasing battery costs enhance the competitiveness of electric vehicles and storage applications in the power sector.

The report focuses on the role of batteries in the transport sector and in the power generation industry ― where battery storage is the fastest growing clean energy technology on the market ― and highlights the key role batteries will play in fulfilling the 2030 commitments made at the United Nations Climate Change Conference (COP28). These include tripling global renewable energy capacity, doubling the pace of energy efficiency improvements and transitioning away from fossil fuels.
