PC Scientists have developed liquid fuels capable of storing solar energy for up to 18 years


No matter how abundant solar energy sources, there is still a problem with its long term storage.

Now, however, Swedish scientists at the University of Champs Lamar Technology have brought a new and interesting solution. They developed a special liquid, called solar thermal fuel, which could store solar energy for more than ten years.

"Solar thermal fuel is like a rechargeable battery, but instead of electricity, you put the sunlight into it, and if necessary, it radiates as heat,"Explains Perry Grossman of MIT In an interview with NBC News.

It is actually a molecule made up of carbon, hydrogen and nitrogen. When sunlight is applied to it, something unusual happens: the bonds between the atoms get organized and a new version called the isomer is formed.

Solar energy is seen between the strong chemical bonds of the isomer and remains there, even when the molecule cools to room temperature. When energy is needed, for example, at night or in winter, the liquid is filtered through the catalyst, the molecule returns to its original form and releases heat in the form of heat.

"Energy can be stored in this isomer for up to 18 years,"Says one of Caspar Maschelsen's scientists at the University of Champs-Elysées.And if we want to spend the energy and use it, we get a bigger rise in the heat than we dared to hope for."

Scientists have tested a new liquid fuel in a prototype system, located on the roof of a university building, and attracted the attention of many investors. They repeated this cycle more than 125 times without significant damage to the molecule.

Researchers say that their liquid kilogram can now store 250 watts of energy, twice the battery capacity of Tesla. They believe, however, that thanks to optimization of design they will soon be able to get even more heat from this system.

If everything goes according to plan, Moth-Poulsen thinks that technology can be available for commercial purposes within 10 years.

The study was published in the journal Energy and environment.
