An international team of researchers (Sweden, China, Spain) has developed a closed energy system called Molecular Solar Thermal Energy Storage Systems (MOST). It is based on a specially designed molecule of carbon, hydrogen, and nitrogen, which when hit by sunlight changes shape into an energy-rich isomer which can be stored in liquid form for later use when needed, such as at night or in winter. A specially designed catalyst releases the saved energy as heat while returning the molecule to its original shape, so it can then be reused in the heating system. In combination with a micrometer-thin thermoelectric generator, the energy system can also generate electricity to order. They have refined the system to the point that it is now possible to store the energy for up to 18 years. According to the researchers the work has great potential for renewable and emissions-free energy production. But a lot of research and development remains before we will be able to charge our technical gadgets or heat our homes with the system’s stored solar energy…read more. Open Access TECHNICAL ARTICLEÂ
