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.
Can molecular solar energy be stored in strained isomeric structures?
Recent advances in the design of molecular have opened up opportunities for storing solar energy in strained isomeric structures and releasing heat on demand, culminating in molecular solar thermal (MOST) energy storage densities over 0.3 MJ kg−1 and validating the potential for achieving thermal
What are solar thermal batteries based on?
The solar thermal batteries based on MOST compounds will enable a solar-chargeable, off-grid, and long-term energy storage in light-weight organic materials that are easily produced from low-cost feedstocks, complementing the state-of-the-art energy conversion and storage technologies.
What is the difference between molecular solar thermal energy storage and PCM?
In comparison, MOlecular solar thermal energy STorage (MOST) materials , , can offer a higher energy density than PCMs without influencing the visible transmittance of light. Unlike sensible and latent heat storage materials, which are charged with heat, the MOST molecules absorb solar irradiation, i.e., photons.
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.
How is solar energy stored in the isomer state?
In the isomer state, solar energy is stored in the chemical bonds of the molecules. When the molecules “switch back”, to the low energy parent configuration, the stored energy (i.e. chemical energy) is released as heat. This charging and heat release cycle can be repeated thousands of times without significant degradation . Fig. 1.
