Concentrating solar power (CSP) is a technology that converts solar energy to heat, then to electricity. CSP can provide dispatchable electricity due to its intrinsic thermal storage capacity, which is able to deal with the intermittency and fluctuation of solar energy resources. Therefore, CSP is one of the most promising power technologies for China’s “dual carbon” goal. However, the levelized cost of energy (LCOE) of current CSP is still high. To reduce the LCOE, the outlet temperature of the solar receiver will be elevated to >700 °C in the next-generation CSP. Because of extensive engineering application experience, the liquid-based receiver is an attractive receiver technology for the next-generation CSP. This review is focused on four of the most promising liquid-based receivers, including chloride salts, sodium, lead-bismuth, and tin receivers. The challenges of these receivers and corresponding solutions are comprehensively reviewed and classified. In the end, suggestions for future studies are proposed to bridge the research gaps for > 700 °C liquid-based receivers.
