This　work　proposes　a　LNG　cold　energy　recovery-freezing　desalination-thermal　storage　coupling　system,　where　the　LNG　cold　energy　drives　an　organic　Rankine　cycle　to　generate　power.　Simultaneously,　seawater　is　subjected　to　cryogenic　centrifugal　desalination,　and　the　desalinated　ice　produced　is　stored　as　a　thermal　storage　medium.　The　thermodynamic　and　economic　analyses　of　the　system　are　conducted.　The　results　show　that　the　daily　freshwater　production　of　the　system　is　119.66　t,　with　a　net　output　power　of　52.10　kW.　The　investment　payback　period　is　3.23　years,　and　the　desalination　cost　is　0.48　USD·t−1,　significantly　lower　than　the　cost　of　traditional　reverse　osmosis　desalination.　©　2024　Science　Press.　All　rights　reserved.
