Gravity energy storage systems

Gravity energy storage systems depend on the principle of lifting one or more solid masses a vertical distance in order to increase their gravitational potential energy. The system must then be reversible to allow the lowering of the weight(s) to result in useful release of the stored energy, less any efficiency losses. The source of energy to be stored is an electrical …

Vesivoiman hyödyt, haitat ja tuotanto

Vettä (ja näin ollen energiaa) voidaan varastoida silloin kun vettä on riittävästi ja sähkönkulutus alhaista, ja käyttää silloin kun sähkönkulutus on korkeimmillaan. Suomessa vesivoimalla tuotetaan vuosittain vaihtelevasti 15-20 % sähköstä, ja Vattenfallin tuotannon osuus on tästä noin 3 %. * Perusenergia = jatkuva sähköntarve
