Xergi, a Danish supplier of turnkey and environmental plants, says that biogas produced from manure and energy crops can help substantially reduce Denmark's greenhouse gas emissions. Biogas can be used not only for CHP stations as it is today, but also for the transport sector, where it could cover more than 20% of fuel requirements in Denmark.
Two research scientists at the Technical University of Denmark (DTU) have prepared an environmental Life Cycle Assessment (LCA) of biogas produced from both maize silage and manure, based on technologies developed by Xergi.
"Biogas from manure stands out for its large reduction in greenhouse gas emissions and very large fossil fuel savings compared to the conventional storage and soil application of the manure, "say Katrine Anker Thyø and Henrik Wenzel of DTU, who made the report which was commissioned by Xergi.
The LCA also shows that it is possible to drive approx. 100,000 kilometres (62,500 miles) in a standard family car with biogas produced from one hectare of maize.
Frank Rosager, the director of Xergi, says that all major car manufacturers today have models which can run on biogas. Germany, which is a leader in using biogas in the transport sector, has more than 700 biogas filling stations.
Xergi plans to use the results from the report to raise political awareness of the benefits of using biogas in the Danish transport sector. The news was reported in an Xergi press release and by Nordjyske.dk.
