Renewable energy constitutes 23% of the Danish energy production and 28.6% of the Danish energy consumption, according to the Energy Agency’s Energy Statistics 2015. Bioenergy is by far the largest contributor of renewable energy, with 60% of the production and 69% of the consumption. The large share of bioenergy is mainly caused of conversion of CHP plants from formerly coal to now biomass, particularly imported wood pellets.
Biomass is one of Denmark’s main renewable energy sources for generating power and heat by combustion and gasification. Denmark has an impressive history of turning waste and secondary agricultural biomass into valuable energy, using most of it for combined district heating and electrical power generation or for upgraded biogas for the natural gas grid. Danish research is also at the forefront of bioenergy with several competitive second generation biofuel production technologies for both bioethanol and biodiesel.
The Danish government has made biogas a cornerstone in the country’s new energy strategy, which targets Denmark to be fossil free by 2050. The specific biogas goal is to use half the country’s slurry to produce biogas which means a tenfold increase of the current situation. To achieve this target, a series of measures will be introduced, i.e. grants to build new plants and higher feed-in tariffs to new biogas applications: upgrade of biogas and its use in transportation.
