More than 200 climate and energy organisations have warned German municipalities against falling prey to gas industry lobbying for including hydrogen in their obligatory local plans for the shift to climate neutral heating. 鈥淗ydrogen is inefficient, unlikely to be available in large amounts, and will therefore remain expensive in the medium and long term,鈥� they argue in an聽聽sent to the mayors of the country鈥檚 more than 10,000 municipalities. 鈥淚ncluding hydrogen in heating plans is therefore a cost trap for municipalities and their citizens. In addition, hydrogen in heat planning jeopardises the national climate targets.鈥� The letter points to a聽聽showing that hydrogen is not suitable for use in heating, because it would require four to six times more energy than using much more efficient heat pumps instead.

The German government聽last year agreed聽a highly controversial plan for the phase-out of fossil fuel heating, which聽obliges municipalities to present a plan聽for the transition to climate neutral heating in their jurisdiction, which can include an expansion of district heating, for example. Large cities have until 2026 to table these plans, while small towns have a later deadline of 2028. In existing buildings and new buildings outside of new development areas, new oil and gas heating systems can continue to be installed until the respective municipality has published a plan.

鈥淲hile the scientific consensus is that hydrogen is unsuitable for heating buildings [鈥�] the gas lobby is promoting the widespread use of hydrogen in heating supply. This is based on just four studies, all of which were commissioned or financed by the gas industry itself,鈥� the letter reads. It points to hydrogen heating lobby initiatives like聽听补苍诲听聽that hope to win over municipal utilities and administrations. 鈥淚f local authorities opt for hydrogen, the gas industry benefits because it can continue to sell natural gas for a very long time and also make potentially high profits with expensive hydrogen,鈥� the letter warns.
