A new high-efficiency biogas plant developed at the Fraunhofer Institute in Germany could accelerate renewable energy production around the globe.
Researchers at the Fraunhofer Institute for Environmental, Energy and Safety Technology have developed a “biobattery” in the form of a highly efficient biogas plant that can turn raw materials like straw, scrap wood and sludge into a variety of useful energy sources. The new plant design, currently being put to the test in a prototype plant in Germany, is said to be highly modular and economically viable even at the small scale.
Current biogas plants only accept few organic substances as raw materials. This new biogas plant could solve this problem by taking a number of materials that would normally have to be disposed of at great cost (like industrial biomass waste, sewage sludge, straw, scrap wood or manure) and process them with high efficiency into a more useful output, all through a highly modular, flexible design.
