Biomass Combustion and Co-firing

Workshop on State-of-the-art technologies for small biomass co-generation, Copenhagen, Oct 7, 2010

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.
