Swedish scientists at Chalmers University of Technology in Gothenburg may have discovered an affordable and effective way to harness solar energy and store it for on-demand use.
The team, led by researcher Kasper Moth-Poulsen, have a system for storing solar energy and later releasing it as heat, as long as a decade after it was first captured. It all starts with a molecule that the researchers created. It is a liquid molecule comprised of carbon, hydrogen, and nitrogen and draws in energy from the sun and holds it until it is triggered for release.
Out of these molecules, Moth-Poulsen and team have developed a transparent coating, a paint of sorts, that can be applied to a variety of objects including home windows, vehicles, or even clothing. To demonstrate the technology, they are coating an entire building on Chalmers University campus.
Moth-Poulsen says “This could be used for heating of electrical vehicles or in houses.”
The project is seeking investors to take the coating material to market and, if funded, could be ready for commercial use in as little as 3 years.
