Absorption　energy　storage　heat　transformer　(ESHT)　is　a　type　of　absorption　energy　storage　system　designed　to　achieve　temperature　lift.　The　system　addresses　energy　supply-demand　mismatches　and　expands　potential　applications　for　low-grade　energy.　This　paper　proposes　a　novel　compression-assisted　double　absorption　energy　storage　heat　transformer　(CDAESHT)　to　improve　the　system　performance.　The　dynamic　characteristics　of　four　operational　modes　with/without　compression　are　comparatively　analyzed.　The　performance　of　the　CDAESHT　and　existing　ESHTs　is　studied　and　compared.　Results　indicate　that　the　CDAESHT　achieves　the　maximum　temperature　lift　of　95　degrees　C　while　demonstrating　superior　performance　over　existing　ESHTs.　Compared　to　the　conventional　ESHT　with　a　maximum　lift　of　37　degrees　C,　the　energy　storage　density　is　improved　from　15.61　kWh/m3　to　38.49　kWh/m3,　the　exergy　efficiency　is　enhanced　from　0.21　to　0.24,　and　the　discharging　time　is　increased　from　66　min　to　122　min.　Moreover,　the　system　performance　exhibits　excellent　stability　as　the　charging　temperature　increases.　The　proposed　system　demonstrates　favorable　economic　performance　and　a　lower　environmental　impact　compared　to　gas　and　electric　boilers.　CO2　emissions　are　reduced　by　11,022.77　kg　(34.81　%)　and　61,277.27　kg　(74.80　%),　respectively.　This　study　can　offer　valuable　insights　for　the　advanced　ESHTs.
