Abstract (en)
[origin: WO2022078834A1] A modular reactor configuration for generating hydrogen (H2) by means of electrolysis in the single-stage configuration thereof and methane (CH4) in the two-stage configuration thereof, with optional gas storage and gas utilization in fuel cells, wherein the single-stage configuration, composed of the electrolyzer (1), the fuel cell (2), the gas stores (3a) and (4a) for separately storing H2 and oxygen (O2), the associated lines (3) and (4), the condenser (5), the H2O vessel (6), the heat stores (7) and (8) and the evaporator (9), is based on the principles of a reversible product cycle for H2 according to figure 1 and can serve both as an electrical energy store and for generating H2 as combustion gas, and the two-stage configuration of which, by way of example according to figure 5 with the additional components of the methanation reactor (11), the lines (12) and (13), the heat exchangers (16) and (17) and the CH4 discharge line (14) in the H2O condenser (15), is based on the extended reversible ideal cycles that describe the possible methanation reactions in said second reactor stage with the reaction equations (6), (7), (8), (9) and (10), which may also take place in parallel, and is thermodynamically equivalent to the reverse reaction in relation to the oxidation of CH4 and thus indicates the best possible structures for further technical implementation.
