The liquid-solar thermal fuel is pumped through transparent tubes to store the energy.
Web Desk – Solar Energy – Converting Energy from Sunlight to Electricity – is the cheapest and most efficient long-term storage for energy.
Various innovations are taking place in the solar industry, and recently Swedish scientists have developed a special fluid and developed a solar thermal fuel that can store energy from the sun for over a decade.
"Solar thermal fuel is like a battery, but instead of electricity, sunlight is shed and receives heat that can be released." Upon request, "Jeffrey Grossman, an engineer working with MIT on these materials, told an international media house.
Researchers at Sweden's Chalmers University of Technology have been working to improve the fluid. Typically, it is a liquid-form molecule composed of carbon, hydrogen, and nitrogen.
When sunlight falls on it, it happens something unusual: the bonds between its atoms are being rearranged and transformed into a new version called an isomer.
As This captures energy from the Sun between the strong chemical bonds of the isomer and remains there as well the molecule cools to room temperature.
When the energy is needed ̵
"The energy in this isomer can now be stored for up to 18 years," says nanomaterial researcher Kasper Moth-Poulsen. Chalmers University said that when the stored energy is recovered, they experience a notable increase compared to the expected Brings results.
The astonishing results have attracted the attention of many investors when a prototype was built o According to the researchers, the energy system was set up for testing on the roof of a university building.
The renewable, emission-free energy device consists of a concave reflector with a tube in the middle, which tracks the power sun like a kind of satellite dish – modeling the system for a circular operation.
The liquid is pumped through transparent tubes, which in turn are heated by sunlight. This turns the molecule "norbornadiene" into a heat-trapping isomer called quadricyclane.
Later, the liquid is stored at room temperature with minimal energy loss.
When the energy is needed, the liquid is filtered through a special filter catalyst, which transforms its molecules back to their original shape by heating the liquid to 63 degrees Celsius.
This heat can be used in home heating systems that provide a water heater, dishwasher, tumble dryer, and more for a building before returning to the roof.
Researchers have passed the fluid through this circuit more than 125 times, absorbing and removing heat without significantly damaging the molecule.
"We have made many significant progress in recent times, and today we have an emission-free energy system that works year-round," said Moth-Poulsen.
The researchers claim that their liquid can now store 250 watt hours of energy per kilogram twice as much as the energy capacity of Tesla's Powerwall batteries.
By further improving and optimizing the system, researchers expect even more energy, at least 110 degrees Celsius.
They expect the technology to be available for commercial use within 10 years if everything goes as planned.
