Based on an innovation from the University of Hohenheim, Wamala Energy developed WE Coolers – mobile solar-powered cooling systems that produce ice cubes. The ice cubes allow large quantities of milk (or other produce, such as fish) to be cooled in off-grid areas without the need for large cold storage facilities. The systems, therefore, increase productivity and income for dairy farmers in rural Uganda.
The venture is based on 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 underway in cooperation with three farmers, with a view to subsequent expansion. With WE Coolers, farmers can cool 600 litres of milk per month, which increases production by an average of 40 litres per day. Because WE Coolers increase farmers' income by 25%, demand in the area is very high, and the venture is currently working on manufacturing more cooling systems to rent to farmers. In 2020, Wamala Energy were finalists in the Climate Launchpad (CLP) innovation challenge.
