Workshop: Small scale biomass co-generation - technology status and market opportunities
7. October 2010
The Danish Society of Engineers (IDA), Kalvebod Brygge 31-33
IDA - The Danish Society of Engineers, Danish Society of Energy (IDA Energi) in co-operation with IEA Bioenergy Task 32 and Task 33.
As of yet, power generation from solid biomass is typically based on conventional steam turbine technologies in combination with a combustion system. However, economy of scale for steam turbines typically makes power generation on a scale smaller than a few MW not financially feasible. Recently however, several innovative prime mover technologies based on other technologies have emerged, that could make electricity generation on a smaller scale financially attractive. These technologies are either based on combustion or gasification of solid biomass, and include ORC technology, Stirling engines, gas engines or other concepts for power generation. Some of these technologies are already offered commercially, others are still in the development stage.
The two working groups on combustion and gasification of biomass, Task 32 and Task 33, under IEA Bioenergy have joined forces with IDA Energi to organize this expert workshop. The purpose is to present an update on the recent developments in relatively small scale (up to 10 MWe) co-generation or power plants based on either combustion or gasification of solid biomass fuels.
We focus on commercial or close to commercial technologies and attempt to take an industrial and market approach.
At the end of the day we summarize and compare the information received from the technology presentations, we evaluate the summary data with experience from the follow-up program on small biomass CHP in Denmark, and we ask an expert panel to review what role small scale biomass CHP technologies may take in the future renewable energy market in Europe.
We wrap up the day with a site visit to Stirling.dk's wood fired stirling engine demonstration unit in Copenhagen.
