Workshop and site visit: 

Cofiring Biomass with Coal

Phoenix hotel
Copenhagen, Denmark

The interest in cofiring biomass with coal continues to grow, due to the relatively high effciency of CO2 mitigation, at often acceptable costs. The potentials are very large.

This workshop addressed several issues related to biomass cofiring, from the resources available, technical approaches, recent experiences, operational challenges and the future perspectives of cofiring. All presentations can be downloaded below.
