Denmark is building the world’s largest biogas plant that will also serve as a research and testing platform. Biogas refers to the mix of CO2 and methane (CH4) produced by bacterial conversion of organic matter under anaerobic (oxygen-free) conditions.
The facility will be built in Foulum, Jutland, and will have an annual capacity of 850,000 cubic meters of methane. Among those participating in the project are the Danish Institute of Agricultural Science (DIAS), the Technical University of Denmark, the Engineering College of Arhus and Agro Business Park.
The biogas facility is an important part of a plan to place Denmark at the world map as a leading country when it comes to biogas and environmental technology. With a facility of this calibre we can run tests with different techniques and biomass. The facility is to house research and development projects. It will create potential for development for both companies in the region and on a nationwide basis.—Søren Mikkelsen, executive vice president of DIAS
The output from the plant, which totals four biogas reactors, is sufficient to cover power consumption for 800 single-family houses and to heat 200 houses. Biogas can also be used as a vehicle fuel.
Denmark already has 20 centralized biogas plants and more than 35 farmscale plants, but has lacked a full-scale testing station. The testing platform will allow researchers to explore different approaches for optimization of the process, such as by combining different kinds of preparation with the use of energy crops like corn, beets and different types of grass.
