Greenhous gas mitigation requires urgent action, especially in transforming the energy system. Bioenergy is expected to counterbalance the variable power from wind and solar energy, but also for the de-fossilization of the heat and transport sectors. This study assesses the wide range of options and evaluates the most costefficient allocation of biomass for 95 % greenhouse gas emission reduction in the German energy system till 2050. The final state in 2050 shows bioenergy in different sectors, including pellet and woodchip boilers, bio-based methane, different combined heat and power concepts, as well as liquid fuels, such as synthetic kerosene. Lignocellulosic biomass makes up the major proportion of future biomass options; however, appropriate strategies are needed to mobilize it.
