Promethean Power manufactures thermal energy-powered milk chillers that have had a giant impact in India. Small diary farmers, as well as distributors like Hatsun, Heritage groups, Mother Dairy, and Amul India have profited from the ability to chill milk quickly and safely.
Indian cleantech startups often struggle to find the talent needed to build an effective team. From "feet on the street" to senior leadership, authentic knowledge of the complex Indian market is key. A leader in this developing market, Promethean is being watched as they negotiate these challenges.
Promethean's system allows for chilling milk at source, which is a win-win for dairy plants and farmers. Dairies get milk with less microbial load and spoilage possibility; farmers benefit from a more flexible delivery time and increased herd size. They can also expect to fetch a better price.
Word is spreading about the transformative impact of Promethean's milk chiller technology. The company has sold over 500 milk chilling units to its dairy partners in India, Sri Lanka and Bangladesh. Retailers are also using Promethean’s system for refrigerating produce.
Sorin Grama and Sam White of Promethean Power are finding their stride in India, where their thermal energy storage technology is making a real difference in the lives of Indian dairy farmers—without using a single drop of diesel.
Promethean Power Systems' Rapid Milk Chiller is a diesel-free, thermal-energy-storage-based refrigeration solution that is manufactured entirely in India. It reduces spoilage, preserves milk quality, and improves the livelihoods of millions of rural Indian dairy farmers.
Milk produced by Indian dairy farmers must get to processing centres before it spoils; otherwise, farmers aren't paid. Without reliable refrigeration, this is a challenge. To help, Promethean Power Systems developed a milk chiller that operates on a thermal energy battery.
Sorin Grama's invention, built from old car parts, can heat water without electricity. It won second place in MIT's annual 100K Entrepreneurship Competition. So what happened when he took his invention to India? Rural Indians told him they didn't need to get water hot, they needed to get milk cold.
The PAEGC team conducted seven site visits in the Indian state of Tamil Nadu, Apr. 27–30, 2016. PAEGC interviewed the operators of milk collection centers, smallholder dairy farmers at the collection centers, and visited Promethean’s milk chiller factory.
Sam White of Promethean Power joined a panel of experts for a free webinar discussing off-grid cooling and refrigeration. Sam spoke about Promethean’s on-the-ground experience in India’s rural dairy industry, using photos to tell his story.
