Storage

 

EES (Electrical Energy Storage) will become increasingly important for integrating intermittent renewable energy sources, achieving a better balancing of the grid, reducing total generation cost and limiting investment in new infrastructure. Storage is also an important element in micro-grids and decentralized generation where it permits better planning of local consumption

Storage

 

EES (Electrical Energy Storage) will become increasingly important for integrating intermittent renewable energy sources, achieving a better balancing of the grid, reducing total generation cost and limiting investment in new infrastructure. Storage is also an important element in micro-grids and decentralized generation where it permits better planning of local consumption.

 

 

Pumped-hydro

 

This is currently the most used form of energy storage (99% of the total). Electricity can be generated in an instant by allowing water stored at higher altitudes to flow through turbines. This allows utilities to balance the grid without the need for power plants that run empty (spinning reserves), only coming on line when energy demand is high. Pumped storage is under the aegis of TC 4: Hydraulic turbines.

 

 

Secondary cells and batteries

 

Secondary cells and batteries are a mature technology which can be used in stationary applications for mini-grid stabilization. Standardization work is undertaken by TC 21: Secondary cells and batteries.

 

 

 

Fuel cell & hydrogen

 

Other storage technologies include fuel cells and hydrogen accumulators which is covered by TC 105: Fuel cell technologies, supercapacitors (TC 69: Electric road vehicles and electric industrial trucks), flywheels and others.
TC 120: EES Systems, is a new Technical Committee that aims to accelerate the integration of renewable energy sources and to produce a more reliable and efficient supply of electrical energy.

 

 

Electrical Energy Storage

 

This IEC White Paper analyzes the role of energy storage in electricity use and identifies all available technologies. It also offers recommendations in the areas of policy (including regulation), research & development, and standardization.

 

 

Grid integration of large-capacity Renewable Energy sources and use of large-capacity Electrical Energy Storage

 

This IEC White Paper provides an overview on the state of the art and future directions for grid integration of large-capacity RE (Renewable Energy) sources and the application of large-capacity EES (Electrical Energy Storage).
