Abstract
A process for storing energy from solar radiation whereby solar radiation is converted into electrical current which is supplied to an electrochemical cell in combination with water and carbon dioxide gas to produce formic acid as an electrochemical storage medium. The formic acid can be easily decomposed by catalysts known in the art into carbon dioxide and hydrogen gas which can be burned as fuel or used as a starting material in numerous commercial applications.
