Hydrogen Heating

Coordinator: Carina Holzapfel
The German government aims to achieve climate neutrality by 2045, and the heating sector must contribute to this goal. However, in 2022, 73% of the residential buildings in Germany were still heated with fossil fuels. The new building energy law requires that 65% of newly installed heating systems must use renewable energy sources. Electric heating, specifically heat pumps, is the most promising option for decarbonizing the heating sector. However, around 30% of residential buildings are in the lowest energy efficiency classes, which poses a challenge for the electrification of heating in these buildings.
With the help of water electrolysis, the heating unit produces hydrogen and then burns it. The use of hydrogen as a fuel produces only water vapor and heat as emissions. The H2mc Heating UG heating unit and process are the subject of a German patent (DE 10 2022 116 119 B3).

An elementary added value of the heating unit and process developed by H2mc Heating UG is the simple and cost-efficient integration. Here, the H2mc heating unit is connected to the already existing heating systems. This is an attractive option especially for the renovation of old buildings with poor energy efficiency classes, as the heating unit can be installed without major conversion work. The system can also be used in new buildings to install climate-friendly heating.
Through W4RES, H2MC is getting funding support to find relevant funding calls. H2MC also receives support for the application preparation for the national fund from “Deutsche Bundesstiftung Umwelt”.
