The sun is an inexhaustible source of energy, access to which, however, is limited due to natural causes – the onset of the night or cloudiness. To overcome this “injustice” took a group of Swedish scientists at the University of Chalmers (Sweden). They developed a liquid energy carrier capable not only of storing and releasing solar energy, but also transporting it.
The technology, called MOST, differs from similar methods by the ability to “place” solar energy directly into chemical bonds without any additional processes or reactions.
The technology is based on the interaction of an organic solution of norbornadiene with light, resulting in the formation of a quadricyclan. The change in the temperature of a quadricyclan triggers a process that converts thermal energy into liquid.
The proportion of converted sunlight in chemical bonds was 1.1%, which is 100 times greater than the previous experimental setup created by scientists four years ago. Her figure was only 0.009%. Also in the new system, instead of the rare and expensive ruthenium metal, carbon elements are used, which are much cheaper.
“The method developed by us will store solar energy in chemical organics and release it in the form of heat if necessary. – explains the head of the project Casper Mot-Polsen. “The combination of chemical energy carriers with water heating using solar panels will allow for the conversion of more than 75% of the captured sunlight.”
