Danish Follow-up Programme for Solid Biomass CHP Plants Small scale biomass co-generation Danish experience and perspective IDA workshop October 7. 2010 Henrik Flyver Christiansen Danish Energy Agency Energy Supply, Bioenergy, Civ. Ing. Henrik Flyver Christiansen Danish Follow-up Programme for Solid Biomass CHP Plants DK Follow-up programme • Started 1993 continued to 2005 on full load. • Process-, fuel-, energy-, environment-, waste water-, ash-, chemical- and economy analysis • Monthly data collection • Continues reporting. • Task group Energy Supply, Bioenergy, Civ.

Henrik Flyver Christiansen Danish Follow-up Programme for Solid Biomass CHP Plants Fundamental consideration • Saving – reduced consumption • Efficiency – reduced consumption • Renewable energy – reorganize production • Long term - Biomass become only carbon resources. Energy Supply, Bioenergy, Civ. Ing. Henrik Flyver Christiansen Danish Follow-up Programme for Solid Biomass CHP Plants Unique Danish position Consumption <=> Production • National power grid – partly storable • National natural gas grid – partly storable • Local district heating – storable • Transport of fuel / product - storable • Information transport – storable Energy Supply, Bioenergy, Civ.

Henrik Flyver Christiansen Danish Follow-up Programme for Solid Biomass CHP Plants DK Follow-up programme Some results: • Combustion : fuel- and ash handling. Plant guarantee. Plant consumption – cut down. • Gasification : Tar- and dust measurement. Guarantee for engine. Basis research. • Common : Standard for fuel. Standard for preforment test. Energy Supply, Bioenergy, Civ. Ing. Henrik Flyver Christiansen Danish Follow-up Programme for Solid Biomass CHP Plants How to make success • Secure delivery of homogeneous fuel • Step by step – don’t do every thing at same time • Development takes time – often more than 10 years for new technology • National network of developer and supplier • New plant don’t work • The staff at the plant • Long term program and a lot of money Energy Supply, Bioenergy, Civ.
