Abstract

Przedmiotem zgłoszenia jest przedstawiony na rysunku sposób magazynowania energii elektrycznej w skroplonym powietrzu, w którym energią elektryczną pochodzącą ze źródła energii, w szczególności źródła energii odnawialnej, zasila się proces sprężania powietrza pochodzącego z atmosfery. Strumień sprężonego powietrza jest następnie schładzany i dławiony, w wyniku czego zachodzi jego częściowe skraplanie, a uzyskaną mieszaninę gazu i cieczy wprowadza się do separatora faz, w którym następuje ich rozdzielenie. Rozdzieloną fazę ciekłą powietrza magazynuje się, a w momencie zapotrzebowania na energię elektryczną przeprowadza się proces jej pompowania, regazyfikowania i rozprężania celem doprowadzenia do docelowego układu odbioru energii elektrycznej. Jednocześnie i równolegle z powyższym procesem wejściowa energia elektryczna zasila elektrolizer, w którym prowadzi się proces elektrolizy doprowadzanego do elektrolizera strumienia wody H<sub>2</sub>O, w wyniku czego uzyskuje się wodór H<sub>2</sub> i tlen O<sub>2</sub>. Otrzymany w wyniku elektrolizy wodór H<sub>2</sub> magazynuje się w zbiorniku ciśnieniowym, a następnie poddaje się procesowi spalania do uzyskania wyjściowego strumienia gorących spalin o wysokim ciśnieniu, które doprowadza się do wymiennika ciepła, gdzie podgrzewa się zregazyfikowane powietrze.The subject of the application is the method of storing electricity in liquefied air, shown in the drawing, in which electricity from an energy source, in particular a renewable energy source, is powered by the process of compressing air from the atmosphere. The compressed air stream is then cooled and throttled, resulting in partial condensation, and the resulting gas and liquid mixture is introduced into the phase separator, where they are separated. The separated liquid phase of air is stored, and when electricity is needed, it is pumped, regasified and expanded to deliver it to the target electricity consumption system. At the same time and in parallel with the above process, the input electrical energy powers the electrolyzer, where the electrolysis process of the H<sub>2</sub>O water stream fed to the electrolyzer is carried out, as a result of which hydrogen H<sub>2</sub> is obtained and oxygen O<sub>2</sub>. The hydrogen H<sub>2</sub> obtained as a result of electrolysis is stored in a pressure tank and then subjected to a combustion process to obtain an output stream of hot, high-pressure exhaust gases, which is fed to the heat exchanger, where the regasified air is heated.
