Zusammenfassung: | A unit (1; 21) for accumulation of energy comprising: an electrolyser (2) designed to provide electrolysis of H2O for producing H2 and O2; a methanation reactor (3) designed to produce CH4 by reacting the H2 produced by the electrolyser (2) with CO2; a direct conduction line of H2 (4) from the electrolyser (2) to the methanation reactor (3); and a thermostatic safety valve (13) arranged on a line (11) for offtake of the CH4, designed to draw off the CH4 produced by the methanation reactor. The electrolyser (2) comprises an electrolytic cell (6) and a tank (7) for supply of water, hydraulically connected to the electrolytic cell (6) for supplying it with water as electrolyte. |
