Pioneering Technology:
Long-Term Solar Energy Storage in Solid Sulphur

The SULPHURREAL project demonstrates an innovative approach to the direct storage of concentrated solar energy in solid elemental sulphur. The basic idea is to use concentrated solar energy to cyclically drive a series of chemical reactions that interconvert sulphuric acid and sulphur. The cycle can also be operated using sulphuric acid and sulphur feedstocks from existing large-scale industrial processes.
