The study showed that up to 40% of the electricity fed into the system can be stored as biomethane, and the system energy flow is most sensitive to the electrolyzer efficiency. The economics of the studied system depend mostly on the electrolyzer investment cost and desired target price for the CH4. The system can be run economically with current electricity prices if the electrolyzer investment costs decrease 60–72% or the price of CH4 increases 20–76% depending on the investment interest and price fluctuation scheme.
