Supplying households with green hydrogen for heating should not play a major role in Germany鈥檚 heating sector decarbonisation because of huge planning and implementation challenges, a聽聽commissioned by the environmental NGO Umweltinstitut M眉nchen has found. Germany鈥檚 larger cities must present heating transition plans by 2026 and smaller municipalities by 2028 to identify which technologies are best suited for decarbonising heating in each area. Areas that are already equipped with a natural gas distribution grid must be examined for their conversion to transporting hydrogen 鈥� if enough of the climate neutral fuel can be made available for this location. Due to the uncertainties arising from this dual conditionality and the uncertainties in municipal planning, the legal experts say 鈥渋t is not possible to reliably assume a hydrogen supply for households鈥�. Houseowners would face 鈥渟ignificant disadvantages鈥� if they prepare for heating with hydrogen but ultimately don鈥檛 have access to enough of the green gas, the legal experts found. 鈥淭ime and resources could be wasted on an unrealistic solution,鈥� they argued. The experts said cities and municipalities should focus on the 鈥渞ealistic feasibility鈥� of given technical solutions, rather than looking for theoretically more attractive alternatives. At the same time, authorities are legally bound to adhere to the principle of cost efficiency, which would mean that unnecessary planning efforts should be avoided, the experts added.聽聽

鈥淢unicipalities should not plan to heat homes with hydrogen because it鈥檚 unrealistic that green hydrogen will be available in sufficient quantities at affordable prices,鈥� energy consultant Wiebke Hansen of the Umweltinstitut M眉nchen聽聽environmental news website Klimareporter.聽She argued that cities and municipalities would benefit from a clear ban on using green hydrogen for heating as this would ensure no more resources are invested in analyzing and planning for a hydrogen distribution infrastructure for heating.

To clean up carbon emissions in the building sector, the bulk of which comes from burning fossil fuels to heat air and water, scientists have pushed for heat pumps running on green electricity and district heating systems powered by a variety of clean sources. The gas industry and some politicians have聽fought hard for hydrogen聽as an additional option to replace gas and oil as a fuel in homes.
