Regio Energie Solothurn (RES), hybrid energy plant
The project involves the development and construction of a peak-load and backup heating plant that links up three different energy networks – gas, electricity and district heating. The plant comprises a power-to-gas (hydrogen) system (with later addition of a methanation facility), a combined heat and power (CHP) station and a thermal store with 300 m3 water capacity. In its completed state, the plant will supply 6 MW of power and 12 MW of heat. The first phase provides 350 kW of electrical power for the storage of electricity in the form of hydrogen (power-to-gas). Some of the hydrogen is stored on site and some is fed into the natural gas network.
