The Potential Roles of Energy Storage in Power Systems

Successfully decarbonising the electric power system requires greater flexibility.  Most grid operators agree that storage technologies that do not emit CO₂ when used will play a crucial role within their networks in the years to come.  These technologies can support and enable the integration of non-dispatchable renewable energy sources into the grid.  Some storage roles are already clear, while others lie in the future.  

This is CIGRE’s first dedicated effort on the use and application of non-emitting energy storage in power system development and economics.  It lays the foundation for future Working Groups to build upon the recommendations of this TB.

This Technical Brochure discusses only energy storage technologies that do not emit CO₂ when used.  The WG organised the TB into six…
