Overall objectives of BIO-CCHP
10.10.2019
• Development of a novel trigeneration system, BIO-CCHP, for production
of electricity, heat and cold from biomass based on:
(i) Biomass gasification reactor (ii) SOFC (iii) Absorption cooling machine
• High flexibility in terms of feedstock, plant size, gasification technology,
load changes and demand of power (max. efficiency), heat and cold.
• Target electrical efficiency: > 40%
• Preliminary estimation of reduction of normalized operating costs
(€/kWh) compared to reference biomass-CHP based on gasification:
approx. 30%
