Method for buffering electrical energy of a power supply system and regenerative energy storage device

摘要

The invention relates to a method (450) for buffering electrical energy of a power supply system. The method (450) comprises a step of receiving (452) the electrical energy via an interface to the power supply system, a step of performing (454) an electrolysis to convert the electrical energy into a chemical reaction energy and an oxidant, and a step storing (456) the chemical reaction energy in a fluid reservoir.
