The fluid – solar thermal fuel is pumped through transparent energy storage tubes.

Web Desk – Solar energy – converting energy from sunlight into electricity – is the cheapest and most efficient long-term energy storage.

Various innovations are taking place in the solar industry, and scientists in Sweden have recently developed and developed a specialized fluid called solar thermal fuel that can store energy from the sun for more than a decade. on demand, "Jeffrey Grossman, an engineer working with these materials at MIT, told an international media house.

Scientists at the Chalmers University of Technology in Sweden work to improve the liquid as a molecule in a liquid form composed of carbon, hydrogen and nitrogen When the sunlight falls on it something unusual happens: the bonds between its atoms are rearranged, transforming into an energized new version called isomer, resulting in the sun's energy being trapped between the strong chemical bonds of the isomer and the rest even when the molecule is cooled to room temperature

When energy is required ̵

Amazing results attracted the attention of numerous investors when the prototype of the Energy System was placed on the roof of a university building for testing purposes, according to the researchers. the sun like some satellite antenna – modeling the system to work circularly.

The liquid is pumped through transparent tubes, which in turn are heated by the sunlight. This enables the norbornadiene molecule in the heat-capturing isomer called quadricyclamine. Later, the liquid is stored at room temperature with minimal energy loss.

When energy is needed, the liquid is filtered through a special catalyst that converts its molecules back into its original form, warming the liquid to 63 degrees Celsius.

The hope is that this heat can be used for domestic heating systems, water heater boiler, dishwasher, clothes dryer and many more.

Researchers put the fluid over this cycle more than 125 times, taking heat and releasing it without significant damage to the molecule. recently, and today we have an emission-free energy system that works all year round, "Mott-Polussen said.

Researchers say their liquid now can store 250 watts of energy per kilogram

By further improving and optimizing of the system, the researchers expect even more power generation, at least 110 degrees Celsius

They expect the technology to be commercially available within 10 years if everything goes according to plan
