Making power clean every hour: 9 clean flexibility tools

The document outlines nine clean flexibility tools categorized into Store, Shift, Share, and Supply to balance power systems and reduce fossil fuel reliance. Key examples include China's 3.6 GW pumped storage station and California's 10 GW battery capacity.

• Clean flexibility tools are divided into four categories: 'Store' (four tools for minutes, hours, and days), 'Shift' (two tools to move non-critical demand to sunny/windy hours), 'Share' (power cables to balance supply and demand across space), and 'Supply' (two tools for rapid ramping of power sources).
• Specific large-scale deployments of storage technology include China's completion of the world's largest pumped storage station in 2024 with 3.6 GW capacity, potentially saving 1.2 million tons of CO2 annually, and a 300 MW compressed air storage project launched in April 2024, potentially cutting 490,000 tons of CO2 annually.
• California's battery capacity reached 10 GW by April 2024, representing a 13-fold increase over five years; these batteries routinely met nearly one-fifth of the state's daily peak evening load in 2024 by shifting solar power.
