It does not matter how abundant are the energy sources of the sun, its long-term storage still has a problem.
Now, however, Swedish scientists from the University of Technology Chalmers have given a new and exciting solution. They have developed a special energy, known as solar-sized fuels, which can store the solar power for more than ten years.
"Solar thermal fuel is similar to a renewable battery, but instead of electricity, you will insert sunlight and, if necessary, it will change as a heat,"Explain Jeffrey Grossman of MIT in an interview for the NBC News.
It's a real idea that's a? including carbon, hydrogen and nitrogen. When sunlight is activated, something unusual will occur: the bits between the atom reorganization and a new version called the isomer will be created.
The energy of the sun is seized between strong and strong chemical connections and is still there, even when the molecule is chilled to room temperature. When energy is needed, for example at night or during winter, the energy is broadcast through the garden, the molecule will return to its; its original shape and heat-heat in the form of heat.
"Energy can be stored in this isomer for up to 18 years,"One of Kasper Moth-Poulsen scientists from Chalmers University says."And if we want to extract and use the energy, we will get a bigger increase in heat than we hope to hope."
Scientists have tested a new fuel test in a prototype power system, based on the roof of a university building, and attracting the attention of investors. They again made more than 125 hours without massive damage to their mills.
Researchers say that the kilogram of slab can now be about 250 watts of energy, twice the battery capacity of Tesla Powerwall. But they believe, that they are. get more heat from this system.
If everything is according to their plan, Moth-Poulsen believes that technology may be available for commercial purposes within 10 years.
The study was published in the magazine Energy & Environmental Science.
