High temperature thermal storage
Energy Storage in Buildings, A Technology Overview (BG 73/2018), written by John Piggott and published by BSRIA in March 2018, sates: ‘Storing heat at higher temperatures creates challenges with regard to the choice of storage medium. Hot water is widely used and pressurising the water increases the amount of heat that it can store before it boils, but this makes the storage vessel more expensive and difficult to manage. In these situations, it is often preferable to use specialist storage media with a very high energy capacity, such as oil or molten salt.’
