In cooperation with the Hamburg Institute (HI) and the Forschungsgesellschaft für Energiewirtschaft in Munich (FfE), the study "Green District Heating for Germany - Potentials, Costs, Implementation" was published in March 2021. The subject of the studies is the necessity of green district heating for the implementation of climate-neutral heat supply on the way to climate neutrality in the heating and building sector in Germany.
To achieve the climate targets, district heating networks must be converted and expanded. Only then can climate-neutral heat be generated and used from large heat pumps, solar thermal energy, geothermal energy, power-to-heat (PtH) and waste heat. In addition to the district heating supply structure, grid temperatures must also be lowered and more heat storage facilities integrated into the heating and building sector. However, according to the study, the adaptation of the Heat Supply Ordinance and changes to the Fuel Emissions Trading Act (BEHG) are also key points on the path to climate neutrality.
The study was commissioned by the German Association of Energy and Water Industries (BDEW) and can be downloaded from the BDEW website. In addition to the points mentioned, the study analyzes further measures aimed at achieving a climate-neutral heat supply in the future. According to statements by BDEW, funding of at least one billion euros per year is required by 2030. The BDEW's "Federal funding for efficient heating networks" funding program is intended to ensure reliable financing.
