Techno-economic Optimisation of Limited Resources in Steam Biomass CHP Plants- Croatian Case Study
Medarac, H., Jäger Waldau, A., Monforti Ferrario, F., Scarlat, N., Szabo, S.
Biomass resources are limited by a number of constraints, including natural capital, competitive uses (for industrial use, paper production, and various energy uses) and sustainability requirements. While resources are limited, their energy use can have many different outputs (heat, electricity, liquid biofuel etc.) In order to improve the overall efficiency of the use of biomass as a primary energy resource, a research project has been carried on the efficiency of energy conversion of biomass fired cogeneration power plants which use superheated steam in Rankine cycle. Results of the research show correlations between the efficiency of the power plant and the use of biomass according to various heat and power production levels. Results can help national, regional and local policy makers to observe the level of heat demand which is needed for a certain area in order to optimize the size of their biomass cogeneration power plants, depending on available biomass resources while the power production depends on the level of energy efficiency which is aimed to be maintained in the system. In this way, renewable energy strategies and action plans can easier meet overall renewable energy targets with more effective use of biomass and financial resources.
