Jun. 26, 2014—In its inaugural round, more than 475 organizations from 80 countries applied to the Powering Agriculture: An Energy Grand Challenge for Development initiative, which offered market-based, clean energy innovations for the agricultural sphere in developing countries. Each of the 11 winning organizations received awards of between $800,000 and $1.5 million to support great ideas from around the globe and offer farmers the solutions they need today and tomorrow.
William Kisaalita of the University of Georgia Research Foundation (UGARF) discusses their refrigeration unit powered on biogas—which is extracted from cow manure. The unit regenerates zeolite plates, which retain their capacity to capture water vapor from the evaporative milk chilling process. Partnered with Smallholder Fortunes, UGARF is refining the design of the refrigeration unit, and testing it with farmers in Uganda. UGARF will work with local manufacturers to secure financing and bring production of the units to commercial scale.
