Abstract:
Use of biomass in a sensible way requires both very high energy efficiency and a high degree of flexibility in the combined heat and power production. The Danish power companies have a long tradition creating highly efficient power plants and since the first Danish Electricity Supply Act from 1976, all new power capacity have been located near cities and designed as energy efficient CHP units. The development of small scale biomass CHP plants in Denmark began 25 years ago. To ensure a high flexibility heat accumulators have been connected to all the plants. The Copenhagen district heating system is large, and at the major power plants heat accumulators have been added. The one at the Avedøre Power Plant consists of 2 large stratified hot water tanks dimensioned for 2 Bars (120 C) and with a capacity of 7 hours of full load operation; this gives the necessary flexibility between power and heat production. This flexibility is fundamental for the current conversion of the AVV1 plant from coal to biomass. The paper highlights the challenges and opportunities biomass based CHP production gives in a future Power marked, with a high share of fluctuating renewable power from wind and solar energy.
