"EU-backed project Molecular Solar Thermal Energy Storage  (MOST)... absorb and store solar energy at room temperature... bicyclic dienes molecules switch to high-energy state when illuminated... all 6 of top scoring molecules differed from original norbornadiene quadricyclane system at crucial point in structure, an expansion of molecular bridge between 2 carbon rings in bicyclic part allowing new molecules to store more energy than original norbornadiene"
