Municipal Heat Planning to Exit from Coal, Oil and Natural Gas in a German Major City
Abstract
Following a decision by the city's municipal council in 2019, a climate protection council was formed in the German city of Kassel as an advisory body to develop possible concepts and measures with the help of specialist groups to outline how climate neutrality can be achieved in Kassel by 2030. A major challenge on the way to a climate-neutral city is the decarbonization of the heat supply. In Kassel, more than 85 % of the heat supply is based on fossil fuels. In order to investigate this transformation process as holistically as possible, using Kassel as an example, various scenarios are being developed for a heat supply without coal, oil and natural gas. These are based on a model for the development of heat demand, a building-specific heat atlas, a comprehensive estimation of the local potential for renewable heat, and an hourly calculation of the heat supply scenarios with a subsequent profitability analysis.
