Wamala: Cooling milk with solar power

Based on an innovation by the University of Hohenheim, Wamala Energy developed WE Coolers – mobile solar-powered cooling systems that produce ice cubes. These ice cubes allow the cooling of large quantities of milk (or other produce, such as fish) without the need for large cold storages. The systems therefore increase productivity and income of milk farmers in rural Uganda.

The venture builds upon the business model that Wamala Energy receives a share of the additional revenue that the farmers earn due to the cooling systems.

Wamala Energy’s market pilot is currently running in cooperation with three farmers. As WE Coolers can increase farmers' revenues by 25%, the demand in the area is very high and the venture is currently working on securing more cooling systems to rent out to the farmers. Wamala Energy participated in the Climate Launchpad (CLP) innovation challenge and emerged 3rd at the national finals in 2020.
