Wind Energy Storage

Detailed overview of innovation with sample startups and prominent university research


What it is

Wind energy storage involves capturing and storing excess wind energy for later use. This is crucial for addressing the intermittency of wind power and ensuring a reliable and consistent supply of renewable energy, even when the wind isn’t blowing.

Impact on climate action

Wind Energy Storage in the Wind Power sector advances climate action by addressing intermittency challenges in wind power generation. By storing excess wind energy during periods of low demand and releasing it during peak times, this innovation enhances grid stability, promotes renewable energy integration, and reduces reliance on fossil fuels, mitigating carbon emissions.

Underlying
Technology

  • Energy Storage Systems (ESS): ESS, such as batteries, pumped hydro storage, compressed air energy storage, and hydrogen storage, store excess wind energy for later use.
  • Power Conversion Systems (PCS): PCS convert the variable frequency AC electricity generated by wind turbines into DC electricity suitable for charging the ESS and vice versa for discharging the stored energy back to the grid.
  • Energy Management Systems (EMS): EMS optimize the charging and discharging cycles of the ESS, ensuring efficient energy utilization and grid stability.
  • Grid Integration: Wind energy storage systems need to be seamlessly integrated into the electricity grid to ensure efficient energy flows and grid stability.
