6 FAQs about [Molecular solar thermal energy storage]
What is molecular solar thermal energy storage?
Molecular solar thermal energy storage systems (MOST) offer emission-free energy storage where solar power is stored via valence isomerization in molecular photoswitches. These photoswitchable molecules can later release the stored energy as heat on-demand. Such systems are emerging in recent years as a vibr
What is molecular solar-thermal (most) energy storage?
The term Molecular Solar-Thermal (MOST) energy storage has been introduced for systems like anthracene, where solar energy is stored by reversible molecular rearrangements [ 15 ]. The reactant, sometimes referred to as the parent compound, must absorb solar light to form a metastable photoisomer, and this process must be reversible.
What are solar energy conversion and solar energy storage?
Solar energy conversion and solar energy storage are key challenges for a future society with limited access to fossil fuels. Certain compounds that undergo light-induced isomerisation to a metastable isomer can be used for storage of solar energy, so-called molecular solar thermal systems.
How can solar energy be stored?
There are many approaches to the storage of solar energy, the simplest is probably hot water or molten salt techniques, which albeit scientifically simple, suffer from the fact that the storage medium must be kept well insulated to avoid thermal losses.
Can molecular photoswitches be used in solar thermal energy storage?
The calculated energy densities of the dimer and trimer systems of up to 927 kJ kg −1 (257 Wh kg −1) and measured densities up to 559 kJ kg −1 (155 Wh kg −1) greatly exceed the original targets of 300 kJ kg -1 15 highlighting the potential of applying molecular photoswitches in future solar thermal energy storage technologies.
Can light induced isomerisation be used for solar energy storage?
Certain compounds that undergo light-induced isomerisation to a metastable isomer can be used for storage of solar energy, so-called molecular solar thermal systems. Exposing the compound to sun light will generate a high energy photoisomer that can be stored.
