Workshop and site visit: 

State-of-the-art technologies for small biomass co-generation

IEA Bioenergy Task 32 and 33, IDA Energi
Copenhagen, DK

This IEA Bioenergy workshop provided an overview of the current development status of several innovative prime mover technologies , which could make electricity generation on a smaller scale financially more attractive. These technologies are either based on combustion or gasification of solid biomass, and include ORC (Organic Rankine Cycle) 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 full report of the meeting, including an evaluation of the different technologies presented, is available here.
