“…SOFC, as a high-temperature fuel cell, demonstrates the capability to generate substantial highpotential exhaust heat, which contributes to its enhanced energy efficiency [13,14]. It efficiently converts chemical energy into electricity and can accommodate different types of fuel for its operation [15,16]. LPG has emerged as an exceptionally promising fuel option for fuel cells, primarily attributed to its cost-effectiveness, ease of storage and transportation, lower flammability compared to alternative fuels, and its inherent safety features, including a detectable odor in case of leakage.…”

This research showcases the seamless integration of solid oxide fuel cells (SOFC) with waste heat recovery systems, utilizing liquefied petroleum gas (LPG) as the primary fuel source. The focus of the study is on efficiently harnessing the cold energy from the LPG supply to produce substantial power for the entire system. To optimize energy utilization, a gas turbine (GT) and steam Rankine cycle (SRC) are integrated to effectively convert waste heat from the system into useful work and power. Additionally, a waste heat boiler (WHB) is incorporated to provide superheated vapor steam for seafarer accommodation. A detailed thermodynamic analysis and investigation of the proposed integrated system are performed. The simulations and optimizations of combined system are conducted using ASPEN HYSYS V12.1. Thermodynamic equations based on the fundamental laws of thermodynamics are employed to estimate system performance indicators, and the exergy destruction in major components is assessed to optimize the system’s design and operation. The proposed system exhibits impressive energy and exergy efficiencies, calculated at 52.65% and 51.10%, respectively. Moreover, the waste heat recovery combined cycles contribute an additional 1,759.73 kW, equivalent to 31.65% of the total system output. The innovative models are validated against experimental data from the literature, demonstrating strong agreement. Furthermore, a comprehensive parametric study investigates the influence of varying the current density from 900 to 1,950 A/m2, leading to a total energy efficiency variation of 41.59%, ranging from 82.45% to 40.86%. The organic Rankine cycle (ORC) performs exceptionally well, capitalizing on both cold energy and high-temperature waste heat to achieve high energy recovery efficiency. The WHB is capable of providing 8,200 kg/h of superheated vapor stream at 151°C and 499 kPa for seafarer accommodation and heating purposes. The economic viability analysis is conducted to assess the potential for investment, maintenance costs, and the payback period associated with the proposed system.

“…Anand Sinha et al [ 28 ] examined the gas turbine exhaust waste heat generated for powering the fuel cell and made a comparative sustainable, qualitative and quantitative performance comparison between SGT, RGT and SOFC-RGT. Also in another study, gas turbine exhaust waste heat has been examined to power fuel cell and two typical intercooled gas turbines and a fuel-cell hybrid system were compared [ 29 ].…”
