Abstract:
Vegetable oil fuelled CHP units save fossil energy sources and greenhouse gas emissions effectively. Today more than 30 enterprises provide vegetable oil compatible CHP units in Germany. The number of plants and the installed electrical power decreased dramatically within the last two years. Reasons therefore are high prices for vegetable oil fuels in the year 2008, accompanied with inadequately performed heat use concepts. Besides that, the amendment of the Renewable Energy Sources Act led to a lack of planning reliability, regarding power feed-in compensation as well as certification issues of sustainable vegetable oil fuels. Small-scale vegetable oil compatible CHP units are predominantly fuelled with rapeseed oil, in plants of higher power ranges palm oil is mainly used. Quality demands for rapeseed oil fuel are defined in the standard DIN V 51605, simultaneously the standardisation of other vegetable oil fuels is in progress. Under German conditions with power feed-in compensation, heat generation costs vary between 0,09 and 0,14 Cent/kWh, depending on the plant size. However a sophisticated heat concept is essential. For higher market relevance of small-scale vegetable oil compatible CHP plants, the administrative expense has to be reduced and reliable framework conditions have to be secured.
