2G Energy AG, one of the internationally leading manufacturers of gas-driven combined heat and power (CHP) systems, has received an order to deliver a purely hydrogen-driven CHP system to Stadtwerk Hassfurt GmbH. Together with the customer, 2G is thereby realizing a project that is groundbreaking in regenerative energy supply in combination with wind and solar energy. Hydrogen burns without emitting any carbon dioxide and almost without any harmful emissions at all, making it significantly more environmentally and climate compatible as a fuel than natural gas. The higher costs incurred in the production of hydrogen to date and the problem of its availability are resolved commercially in the project through making recourse to local regenerative wind and solar energy producers. The hydrogen is produced by a power-to-gas-system located in the port of Hassfurt. This utilizes surplus electricity generated by the wind park in the adjacent Sailershäuser Forest for the electrolysis of the water. The CHP system then reconverts the hydrogen into electricity and heating in line with demand, achieving efficiencies of > 90%. The electricity from the CHP system is fed into the city’s electricity grid. The heating is to be transferred to a neighboring malt factory, a school and a kindergarten via a heating grid that has yet to be constructed.
