> The solar energy system created at Chalmers back in 2017 is known as ‘MOST’: Molecular Solar Thermal Energy Storage Systems. > The technology is based on a specially designed molecule of carbon, hydrogen and nitrogen that changes shape when it comes into contact with sunlight. > It shape-shifts into an ‘energy-rich isomer’ - a molecule made up of the same atoms but arranged together in a different way. The isomer can then be stored in liquid form for later use when needed, such as at night or in the depths of winter. > A catalyst releases the saved energy as heat while returning the molecule to its original shape, ready to be used again. So it's like a solar panel except that there's a chemical 'hold' step in between the solar and heat phases.
