Résumé

The thermodynamic performance of a two-stage high-temperature heat pump (HTHP), utilizing water/steam as a refrigerant, along with two distinct thermal energy storage systems, concrete sensible heat storage (SHS) and strontium bromide/water thermochemical energy storage (SrBr 2/H 2O TCES), were evaluated. The proposed HTHP demonstrated sufficient capability to supply heat above 200°C with a high COP of 5.2-7.5. While concrete SHS cannot release heat beyond the temperature at which it was stored, 190°C, TCES can release heat above 200°C. Additionally, the SHS system cannot satisfy the limited heat release operation time when it has a lower cycle out temperature than the condensation temperature of the HTHP cycle. It was also observed that SrBr2/H 2O TCES required 45% less material mass and 68% less volume, respectively. In the techno-economic evaluation, the integrated system comprising HTHP and TCES yielded a net present value of €454,075-€171,890. Furthermore, the internal rate of return was calculated to be between 15.3-23.0%.
