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.
Brian Jensen of SunDanzer discusses their small-scale portable cooling system tailored for use in the Kenyan dairy market. The system comprises a photovoltaic refrigerator (PVR) that uses solar energy to cool a chest refrigerator. This technology may use a battery for energy storage or phase-change materials—substances which are capable of storing and releasing large amounts of energy—or a combination of both. SunDanzer will evaluate freezing phase-change material into “milk packs.” The portable milk packs retain their cold temperature overnight, and in the morning, farmers use them to keep collected milk cold in sterilized aluminum milk containers as they transport it to dairy processing facilities.
