Energy storage projects can help stabilize power flow by providing energy at times when renewable energy sources aren''t generating electricity—at night, for instance, for solar energy installations with photovoltaic cells, or during calm days when wind turbines don''t spin.
6 · Deploying battery energy storage systems will provide more comprehensive access to electricity while enabling much greater use of renewable energy, ultimately helping the world meet its Net Zero decarbonization targets.
This is only a start: McKinsey modeling for the study suggests that by 2040, LDES has the potential to deploy 1.5 to 2.5 terawatts (TW) of power capacity—or eight to 15 times the total energy-storage capacity deployed today—globally. Likewise, it could deploy 85 to 140 terawatt-hours (TWh) of energy capacity by 2040 and store up to 10
Energy storage. Storing energy so it can be used later, when and where it is most needed, is key for an increased renewable energy production, energy efficiency and for energy security.
