Cost-effective and flexible polygeneration units for maximised plant use
Research Project, 2018 – 2021

This project develops a polygeneration concept which, by providing a dynamic and flexible mix of power, heat and biogas/bioproducts, represents a robust potential for increasing the use of renewable fuel in the Swedish energy system. As the concept studied uses fluidised bed technology it is especially suitable for the conversion of the share of renewable fuel without potential to contribute to a circular economy. Existing boilers can relatively easy be retrofitted into polygeneration reactors and thereby enable maximized utilization of these units – whose current yearly averaged power load lies at 23% and 46% (for district heating and industrial units, respectively)[1]. Through the development of dynamical models at reactor and process levels, the polygeneration concept will be assessed under selected representative scenarios. The evaluation will focus in the ability to meet a varying demand of the main production while providing a flexible mix of other renewable products.
