National Laboratory for Sustainable Energy, Risø DTU
Description of the organization
Risoe is part of the Technical University of Denmark (DTU) and is The National Laboratory for Sustainable Energy in Denmark, with research groups within bio energy, wind energy, fuel cells, optics, nuclear research and systems analysis. The Biosystems department has 3 research groups working with bio energy production and conversion and environmental impacts studies. The department has a staff of 100 scientists and technicians.
Expertise and experience of the organization
The department has many years of experience in long-term greenhouse gas flux measurements, ecosystem manipulation, soil chemistry, plant nutrition, risk assessment in plant and energy production and biomass conversion to bio fuels and bio materials. The Biosystems department has coordinated and participated in numerous national and international ecosystem research projects with particular focus on biogeochemical cycling and impacts of air pollution and energy production on terrestrial ecosystems – forest, agriculture, grass- and shrublands. The Biosystems department is a leading European research group in designing and conducting large field scale ecosystem manipulation experiments with external drivers such as nitrogen, climate and CO2. Risø DTU is a leading Danish Research Institute within large-scale field measurements by eddy covariance techniques in both forest and agricultural ecosystems. The department has strong experience in measuring atmosphere-biosphere exchange of C and N compounds, use and measurements of stable isotopes, soil-microbe interaction in C and N turnover, soil water transport of chemical elements, advanced greenhouse facilities and assessment of environmental impacts on ecosystem functioning.
