Abstract
Abstract For a successful energy transition, Power‐to‐Gas (PtG) offers the opportunity to convert renewable electricity to substitute natural gas. This renewable synthetic natural gas (SNG) can be used for long‐term storage, transport, or can be integrated into other energy sectors. Main challenges for the commercial application of PtG are to achieve a high PtG process efficiency, dynamic operation capability, and low investment and production costs. Within the STORE&GO project, three demo sites were developed, operated, and evaluated. An overall efficiency of > 75 % is possible, the SNG production costs are expected to drop to less than 10 €‐Cent kWh −1 in 2050.
