Innovative heat storage material

June 6, 2023 – Researchers from the SPECIFIC Innovation and Knowledge Centre and COATED M2A programme at Swansea University have collaborated with the University of Bath to make a groundbreaking advancement in thermal storage research, They developed a new efficient material based on alginate, an inexpensive, abundant and non-toxic seaweed derivative. The process starts with the dissolving of sodium alginate in water. Following this, expanded graphite is added, and a method of gelation is chosen. Once sufficient salt diffusion has occurred, the synthesised beads are filtered and dried at 120°C.
The research and results were published last May in Journal of Materials Science.
