Energy Storage, Distribution, Use and Climate Impact
Keyword(s):
The large-scale energy grid often comprises both AC and DC transmission lines. DC transmission at ultrahigh voltages is more efficient, but consumers need AC at lower voltage so that AC/DC conversion stations are key elements. In modern conversion stations large silicon thyristors are key devices. Energy storage in pumped-hydro installations can be supplemented by compressed air storage. Thermal plants can store energy in molten salts to provide continuous power for consumers. Battery technology is expensive at grid scale but is expanding. The possibility of carbon capture at power plants is discussed. Energy in this chapter is assumed to be electrical energy, with a large portion devoted to the electric grid.
