Electrical energy storage technologies

Electrical energy can be stored using a variety of technologies, for example:
  • Electrochemical storage (conventional chemical batteries)
  • Super capacitors
  • Fly wheels
  • Pumped water
  • Super conducting magnetic energy storage
  • Electrolyzer/Fuel cells

Detailed descriptions of the different storage technologies can be obtained from the website of the Investire project and from other Internet resources (see references) and so are not discussed in more detail on this website.

Electrochemical storage can be achieved with various technologies:

A summary of characteristic data of the different mentioned storage technologies is given in table 1a/1b and figures 1 and 2. The comparison of the various storage technologies is complicated by the differences in the required inverters or control equipment.
