How a breakthrough solar thermochemistry process that uses direct solar heat to cycle between sulphur and sulphuric acid would generate “virtually unlimited” seasonal thermal energy storage Researchers are now refining a groundbreaking long-duration thermal energy storage technology in the SUPHURREAL project Molten salts are currently state-of-the-art for solar thermal energy storage. But elemental sulphur has … Continue reading A solar sulphur cycle to make unlimited thermal energy storage
