How can solar energy be stored for electricity and heat production?

Another promising way to store solar energy for electricity and heat production is a so-called molecular solar thermal system (MOST). With this approach a molecule is converted by photoisomerization into a higher-energy isomer. Photoisomerization is a process in which one (cis trans) isomer is converted into another by light (solar energy).
