The Danish Bioenergy team (Roskilde University and Region Zealand) assists the symbiosis center and local companies in redesigning the energy system. The Bioenergy Promotion 2 project provides vital knowledge inputs to the key stakeholders about sustainable bioenergy resources and efficient conversion routes.
One of the tasks in the Bioenergy Promotion 2 project is to is to utilize the results and experiences from the main stage project to further improve the strategy development and implementation on local and regional scale in the seven demo-regions. One of these demo-regions is the Kalundborg area in Denmark.
The Danish bioenergy team, which consists of the two partners Roskilde University and Region Zealand, is supporting the industrial symbiosis center in Kalundborg in their effort to further develop the industrial symbiosis and diverge energy supply away from coal and towards bioenergy instead.
Kalundborg is of specific interest as it hosts the internationally-known industrial symbiosis. Kalundborg Industrial symbiosis is an industrial system in which a group of companies utilize waste from one company as input for the next company and thereby reducing environmental impacts and overall resource consumption.
The industrial symbiosis in Kalundborg is organized around a large coal-fired power station. The power station is under pressure to implement significant changes in order to comply with national and local energy policy targets. This include the phase-out of fossil fuels at the power station and introduction of renewable energy sources such as biogas, wood and straw incineration and introduction of new energy technologies such as anaerobic digestion and thermal gasification. The system furthermore has to be compatible with an overall Danish energy system relying of huge amounts of fluctuating wind power.
The political plan is to have approximately 50% of electricity coming from wind power in Denmark by 2020 compared to a little more than 20% today. The large share of wind power creates demand for flexibility in consumption and production of electricity and thereby influences the design of the local energy system in Kalundborg.
The greening of the symbiosis also requires integration between the industrial symbiosis and the renewable energy base in the region with a special focus on the agriculture which in Denmark is the main supplier of local bioenergy resources such as manure for biogas production or straw for combined heat and power incineration.
The Danish bioenergy team assists the symbiosis center with knowledge-inputs about bioenergy and more specifically with issues such as bio-resources, resource consumption, CO2 emissions and energy conversion technologies. The knowledge feeds into the strategy development that eventually will result in decisions about the design of the future green energy supply in the demo-region.
