Such photoisomers are referred to as molecular solar thermal energy storage systems (MOST), also known as solar thermal fuels (STF). In this review, we introduce the functional principles and criteria of a general MOST system, then introduce to a broad audience three key candidates and show the efforts made so far to achieve …

The MOST project aims to develop and demonstrate a zero-emission solar energy storage system based on benign, all-renewable materials. The MOST system is based on a molecular system that can capture solar energy at room temperature and store the energy for very long periods of time without remarkable energy losses.
