Cornell technology makes small scale biogas more feasible

Biogas can be made on a farm or landfill scale with simple technology. Removing the hydrogen sulfide, however, has been a more complicated process and not suited to small scale. It is toxic and needs to be removed for many applications and to reduce pollution. Scientists at Cornell have developed a small scale solution for removing hydrogen sulfide that is suitable for farms and other locations outside the large refineries. Biogas than then be used in properly equipped engines for electricity generation, transportation, and other work.

Cornell Chronicle: Cornell technology makes biogas greener: "Cornell plant scientists have invented a new method that uses manure and other farm byproducts to remove toxic hydrogen sulfide from biogas -- a renewable energy source derived from the breakdown of animal waste."
