Efficient utilization of low-grade thermal resources is essential for reducing industrial emissions and improving energy efficiency. Absorption heat pump transformers (AHPTs) can upgrade waste heat and enable combined heat and power (CHP); however, practical designs must balance heat and power production while maintaining crystallization-free operation. This work develops and thermodynamically evaluates two Type III AHPT-based cogeneration configurations via steady-state modeling and a parametric analysis of key operating variables: (i) AHPT-CHP (Absorption Heat Pump-Transformer–Combined Heat and Power), which integrates dual-stage absorption cycles to co-produce net power and revalued heat; and (ii) AHPT-CHDP (Absorption Heat Pump-Transformer–Combined Heat and Dual Power), which builds on AHPT-CHP by integrating an Organic Rankine Cycle (ORC) to convert upgraded absorber heat into additional electricity. Across the explored conditions, AHPT-CHP delivers 9.3–10.0 MW of revalued heat (up to 15 MW near the thermodynamic boundary) and 1.24–1.51 MW of net power, reaching a maximum exergy efficiency of 63.5% within a high-performance window ( GTL≈ 45–55 °C, ≈ 160–180 °C). With ORC integration, AHPT-CHDP more than doubles net power to 2.0–3.2 MW, with exergy efficiencies of 52.8–54.1%. From an environmental perspective, AHPT-CHDP achieves avoided emissions of 30,800 tCO2e/year on average, with peaks of 41,300 tCO2e/year under favorable renewable or waste-heat inputs. These results support the potential of AHPT-based integrations as a scalable option for low-enthalpy waste-heat valorization and emissions mitigation in industrial energy systems.
