Numerical Thermal Back-calculation of the Kerava Solar Village Underground Thermal Energy Storage

Mechanism of thermal reversal of the (fulvalene)tetracarbonyldiruthenium photoisomerization: toward molecular solar-thermal energy storage.

In the quest to harness solar energy for power generation, most efforts are centered around photoinduced generic charge separation, such as in photovoltaics, water splitting, other small-molecule activation, and biologically inspired photosynthetic systems. In contrast, the direct collection of heat from sunlight has received much less diversified attention, the bulk devoted to the development ...

Thermal energy storage for CSP (Concentrating Solar Power)

— The major advantage of concentrating solar power before photovoltaic is the possibility to store thermal energy at large scale allowing dispatchability. Then, only CSP solar power plants including thermal storage can be operated 24 h/day using exclusively the solar resource. Nevertheless, due to a too low availability in mined nitrate salts, the actual mature technology of the two tanks molte...

Photoswitchable Molecular Rings for Solar-Thermal Energy Storage.

Solar-thermal fuels reversibly store solar energy in the chemical bonds of molecules by photoconversion, and can release this stored energy in the form of heat upon activation. Many conventional photoswichable molecules could be considered as solar thermal fuels, although they suffer from low energy density or short lifetime in the photoinduced high-energy metastable state, rendering their prac...

Numerical investigation on sensible thermal energy storage with porous media for high temperature solar systems

In this paper different high temperature TES components are numerically analyzed. The difference is defined by the different type of porous medium employed in the storage. Two different porous media are considered: spheres or foams. In all cases a ceramic material is considered. In the formulation of the model it is assumed that the system geometry is cylindrical, the fluid and the solid thermo...
