Cold storage warehouses (CSWs) are large energy consumers and account for a significant portion of theglobal energy demand. CSWs are ideally suited for solar renewable energy, as they generally have largeflat roofs and their peak demand can coincide with the sun shining. A challenge with fluctuatingrenewables is their variability,which means generation may not coincide with demand. Liquid air energystorage (LAES) is a technology that stores electrical energy as a cryogenic liquid. This paper presents twostrategies for using LAES at CSWs, firstly to shift the import of energy from peak to off-peak tariffs andsecondly to store on site renewable energy when there is a surplus and use when not. The financial viabilityof these strategies is then investigated taking into account the capital cost of the LAES and the money thatcan be saved due to the differences in tariffs at different times.
