Mechanical: Direct storage of potential or kinetic energy. Typically, pumped storage hydropower or compressed air energy storage (CAES) or flywheel. Thermal: Storage of excess energy as heat or cold for later usage. Can involve sensible (temperature change) or latent (phase change) thermal storage.
[pdf] Natural gas distributed energy systems have developed rapidly owing to their high efficiency, low environmental impact, high energy supply reliability, and good economic returns. As the main users of natural gas dis.
[pdf] The first were installed in 2009, and are not associated with storage. The installed capacity is 13 MW, in particular via the Longoni power plant, inaugurated in 2010. Solar energy is the only renewable energy with significant development potential on the island; the wind potential (22 MW according to a study) would not lead to a significant production because the wind blows only 6 months per year.
