Hydrothermal Carbonization: Influence of Plant Capacity, Feedstock Choice and Location on Product Cost

B. Wirth, G. Eberhardt, H. Lotze-Campen, B. Erlach, S. Rolinski & P. Rothe
Pre­treatment of raw biomass with hydrothermal carbonization (HTC) increases the energy density, facilitates mechanical dewatering and improves properties, such as grindability, for use as a fuel in existing power plants. This paper analyses the effects of HTC plant size, feedstock choice and biomass supply logistics on the HTC product costs. A case study for the German federal state of Brandenburg is presented, where optimal locations for HTC plants are determined with a mathematical programming model...
