Danish researchers find power and fertilizer from show

November 13, 2013 |

In Denmark, Biomass DTU, DONG Energy and Bregentved Gods estate intend to show that agricultural biomass can be used both as a renewable energy source and as a substitute for costly fertilizer. Thermal gasification converts biomass into a combustible gas in an oxygen-poor environment, the bi-product being bio-ash. The gas can then be used to produce electricity and heating, as thermal gasification exploits 90-95 per cent of biomass energy.

In 2012, researchers began a series of practical thermal gasification and bio-ash tests together with Bregentved Gods estate and DONG Energy. Bregentved Gods estate is one of Denmark’s biggest farms with 3,284 hectares of agricultural land. The estate uses the straw for soil improvement and is therefore ideally suited for the alternative straw treatment.
DONG previously acquired a thermal gasification unit developed by DTU and has now installed a 6 MW demonstration facility in Kalundborg called Pyroneer. The plant currently produces large volumes of pure bio-ash from straw.
