According to the Rockefeller Foundation, in developing countries like Nigeria, 45% of food is lost due to the absence of cold storage. This leads to a 25% loss of annual income for smallholder farmers.
The ColdHubs are 3 x 3 metres and have solar panels on the roof. Each hub can store up to 3 tonnes of food arranged in 30 kg crates. They use natural refrigerants, which minimises the environmental impacts of the cooling. The ColdHubs are installed at markets and farm co-operatives. Farmers and retailers can rent space in the cold-hubs and only pay per crate of food stored per day. Excess solar power is stored in batteries to ensure the hubs are kept cold at night and in bad weather.
ColdHubs already has 287 customers using the five hubs that have been installed at different sites in Nigeria.
