Energy Supply, Bioenergy, Civ. Ing. 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

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
