6 FAQs about [Solar salt dissolution power generation efficiency]
Is solar high-efficiency and salt-rejection desalination possible?
A total efficiency of 354% was achieved alongside the success of salt rejection in each stage, indicating a new pathway for passive solar high-efficiency and salt-rejection desalination. Solar distillation is one of the important approaches for sustainably obtaining fresh water with zero carbon discharge 1, 2, 3, 4.
How does salt-rejection solar evaporation work?
For conventional salt-rejection solar evaporation systems, water evaporation is confined to the solar absorber surface, and the salt backflow is accompanied by an undesired heat dissipation from the solar absorber to bulk water, thus resulting in a low evaporation rate. This limitation can be solved to a considerable extent by our 3D evaporator.
Are solar distillation devices effective in desalination processes?
Here we elaborately fabricated solar distillation devices based on reverse-evaporating water layers of millimetre-scale thickness and successfully realized simultaneous high efficiency and salt rejection during solar desalination processes.
Are salt gradient solar pond hybrid systems effective?
With the integration of salt gradient solar pond hybrid systems, a maximum lower convective zone (LCZ) temperature of 90 °C, more than 50 % energy/exergy efficiency, and power generation of up to 5 MW are reported in this review.
Can solar-driven reverse distillation improve solar-to-water conversion efficiency?
Solar-driven reverse distillation integrated with thermal localization has shown attractive solar-to-water conversion efficiency. Solar distillation devices based on reverse-evaporating water layers of millimetre-scale thickness successfully realize simultaneous high efficiency and salt rejection during solar desalination processes.
Does salt crystallization change the solar steam generation rate?
Even with salt crystallization at the apex, the solar steam generation rate does not obviously change (~2.24 kg m −2 h −1 under one sun illumination, and ~0.81 kg m −2 h −1 in darkness). Micro-CT images show that channels can be found inside the salt (Fig. 4g and Supplementary Movie 5).
