A solar thermochemical model with a biomimetic leaf-type hierarchical channel is shown in Fig. 1.The heat from the solar radiation at the front of the reactor is absorbed by the solid, resulting in a high temperature environment. CH 4 and H 2 O absorb the heat and undergo a chemical reaction to generate H 2 and CO during the flow …
A novel lead-free (1 – x)CaTiO3-xBiScO3 linear dielectric ceramic with enhanced energy-storage density was fabricated. With the composition of BiScO3 increasing, the dielectric constant of (1 – x)CaTiO3-xBiScO3 ceramics first increased and then decreased after the composition x > 0.1, while the dielectric loss decreased first and increased. For the …
To cope with this problem, this paper proposes an energy-recovery method based on a flywheel energy storage system (FESS) to reduce the installed power and improve the energy efficiency of HPs. In the proposed method, the FESS is used to store redundant energy when the demanded power is less than the installed power.
