Abstract
In the current study, a novel hybridized system for vehicle applications is proposed, analyzed thermodynamically through energy and exergy approaches and evaluated through energy and exergy efficiencies. The current system comprises gas turbine set running on compressed natural gas (CNG), Li-ion battery, CNG tank, two generators, electric motor, power control unit (PCU), thermoelectric generator (TEG), organic Rankine cycle (ORC) and an absorption chiller system (ACS). The overall energy and exergy efficiencies of the proposed system are found to be 38% and 34% respectively at net output power of 63.6 kW from the turbine set. The maximum exergy destruction rate is found in the combustion chamber followed by the TEG unit. For a detailed analysis of the proposed system, a comprehensive parametric study is further carried out to detect the effect of varying the operating and ambient conditions on the system performance.
