The salt used may be 60% sodium nitrate, 40% potassium nitrate with melting point 220°C. Spain's 150 MWe Andasol plant stores heat at 400°C and requires 75 t of salt per MW of heat. It also uses diphenol oxide or oil for heat transfer and molten salt for heat storage. Its condensers require 5 L/kWh for cooling.

fatty acid (PUFA) arachidonic acid (ARA) can account for over 50% of the lipid content [2]. M. alpina is nonpatho-genic and nonallergenic, including the spores produced during the industrial production of ARA [3] which is widely used in food ingredients [4]. ARA has been pro-duced at levels up to 19.8 g/L in 5 L cultures grown over 7 days [5].
