Abstract
While exploiting natural resources, human beings have also left irreversible damage to the environment. The salt caverns left behind by the mining of salt are one of them. With the proposal of the “dual carbon” background, clean power and energy storage power stations have also become one of the focuses of sustainable development. The abandoned salt cavern is combined with the energy storage power station, and the excess electric energy is used to compress the air during the low power consumption period through the non-supplementary combustion mode, and the air kinetic energy is converted into electric energy during the peak power consumption period to realize the zero-carbon salt cavern energy storage conversion. This method can not only achieve zero carbon utilization of the abandoned environment, but also achieve energy storage and conversion, which is a very meaningful research. Based on spherical fuzzy sets, cumulative prospect theory and VIKOR, this paper constructs a novel combined research framework to analyze the risk of zero-carbon salt cavern compressed air energy storage (SAES) power station, and takes China ‘s first zero-carbon SAES power station project as an example. The results show that the overall risk of the zero-carbon SAES power station is 0.3467, which is a low risk. The key risks are non-supplementary combustion thermal energy storage technology risk, salt cavern creep and leakage risk, and the risk tolerance limit is +31.54 %.
