CHP plants based on biomass are complex and challenging plants compared to most other CHP technologies, mainly due to the influence of the fuel on plant performance and economy. However, biomass also has several advantages compared to e.g. fossil fuels, being potentially CO₂ neutral and a widely distributed energy source. This report presents and discusses a number of aspects connected to biomass CHP, regarding technologies, cost-efficiency considerations, Norwegian framework conditions and research challenges connected to the relevant biomass CHP technologies. Depending on the framework conditions several scenarios can be envisioned with respect to the future of biomass CHP in Norway. The selection of the small-scale CHP technology or sub-system technology to be studied in detail in the last two years of the KRAV project should be based on one or more of the following criteria:

1)      Established technologies with significant potential for improvements or retrofit solutions
(e.g. biogas fired superheaters)

2)      Technology combinations with focus on increased electric efficiency (e.g. system analysis
of such combinations)

3)      General fuel aspects directly influencing the cost-efficiency of biomass CHP plants
(e.g. corrosion and fouling)

4)      General fuel aspects influencing emissions from biomass CHP plants (e.g. NOx)

5)      Technology aspects directly influencing cost-efficiency and emissions from biomass CHP plants (e.g. grate design)

6)      New CHP technologies that have the potential to become of significant importance in
Norway within 2020 (e.g. gasification based)
