Emergi is a renewable energy technology start-up, with a mission to create social impact by developing sustainable energy products. Emergi is developing products whose underlying technology uses evaporation to create cooling or freezing effects. The process of a vapour collecting on a surface (adsorption), or its release from a surface (desorption or evaporation) create temperature changes. Evaporation has a cooling effect – like human perspiration- and Emergi has developed ways to amplify this effect using different surfaces and liquids. Emergi is currently developing two products, based on this evaporative cooling, to fill missing links in the cold chain in Sub-Saharan Africa (SSA):
1) Fr-ease – a compact zero-carbon and zero-electricity ice-maker
2) Cooltainer – a large-scale container sized sustainable cool cell
