Chalmers University of Technology in Gothenburg, Sweden has come up with an alternative system with which to store solar power called Molecular Solar Thermal (MOST). The liquid storage technique differs in that it stores energy directly within the bonds of a chemical fluid and replaces a rare metal, ruthenium, with carbon-based elements, which respectively makes it easier to release heat while lowering cost.

"Combining the chemical energy storage with water heating solar panels enables a conversion of more than 80 percent of the incoming sunlight," says Kasper Moth-Poulsen, team leader and associate professor of chemistry and chemical engineering.
