Sweedish researchers have developed a new liquid that can keep sunlight warm for almost two decades.
The main problem of solar energy is that we still do not have the energy to sustain long-term and long-term storage. Our only realistic option is batteries at this time, but they are quite expensive, rare or contaminated material and have limited capabilities. However, the current research can be achieved exactly as the industry needs – a new compound, a special liquid called solar thermal fuel, can save and release sunlight for up to 18 years.
"Energy in this is now stored in 18 years," said one of the team's researchers, Casper Mat Pullen, from Schallmers University.
"And when we take energy and use it, the heat is rising, the greater the better than we were."
Solar fuel performs a recurring battery that replaces solar and heat power instead. The hard part of the team is the molecule (Norbordin) liquid form that researchers from the Swedish Technology University of Technology are developing in a year. It consists mainly of carbon, some hydrogen and nitrogen atoms thrown in. So far, it is a fairly standard organic compound.
What makes this fluid distinguish its interaction with the sun. In the light of the sun, bonds between molecular atoms will be revived and stabilized in energy forms – isomer (so called quadracyclan). It transforms solar energy energy into energy, which can be stored and released. ISOMER itself is stable enough to last up to 18 years (which is a lot), even in room temperature.

When energy is needed, the "fault" liquid can be obtained through the catalyst that addresses the molecule's original form. Excess chemical energy is given as heat.
Prototype rigging The tests are underway in one of the university's buildings using the new fuel, adds the team. The system is based on a circuit that forms a liquid through transparent pipes under the tibial reflector (this is focused on fueling the sun). The installed fuel is then stored. The whole montage looks like the sun, in terms of the sun, because it moves across the sky.
When energy is needed, liquid is filtered through a catalyst, heated to 63 degrees (113 degrees Fahrenheit). The team hopes that the heat can be used for different roles around the house – heating systems, dishwashers, everything and everything – really – until the roof is still on the roof.
"We have a lot of decisive progress, and today we have an emission free energy system that has been working all year long," said Pt.
So far, researchers have maintained their fuels with 125 such cycles without any serious damage to the molecule. In addition, they say that one kilogram of fuel can save up to 250 watt energy – what is double, what does Tesla Powerwall mean? However, they are confident that there are still places where fuel can be improved. They hope that the system will develop at least 110 degrees (230 degrees Fahrenheit) to further revisions.
"There is a lot to be done, we just got the system to work, now we have to do everything to make everything work better," says Moth-Poulsen.
Moth-Poulsen believes that technology can be used for 10 years for commercial use.
