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.
Sorin Grama of Promethean Power Systems discusses their refrigeration solution that uses a thermal energy battery pack that charges on solar power and/or a few hours of grid electricity. This provides cold storage around the clock despite inconsistent access to electricity. Dairy processors can collect raw milk from remote dairy farmers and keep it cold in a rapid milk cooler, reducing the time that milk is unchilled by 75 percent. Promethean will design and deploy the refrigeration systems in collaboration with India's largest private dairy and one of India's largest solar installers.
