A Novel Model of Integrated Combined Cycle Power Plants with ORC, ABRC and Hydrogen

In this paper, a novel combined system driving a Brayton Cycle has been studied for power generation. The suggested power systems plants basically consist of combined power cycle, organic Rankine cycles, and absorption cooling system. The fuel used in the system is 100% methane and a mix of 80% methane and 20% hydrogen. The main factors in the development of sustainable energy are increasing the efficiency of energy conversion in the use of available resources and minimizing environmental impacts, where waste heat recovery is one of the important ways to achieve these goals. In these systems, the recovered waste heat was used for power production, heating, or cooling. Thermodynamic equations were used to develop a mathematical model of the system that was designed. An analysis and comparison of the thermal performance of the proposed systems from an environmental and energy point of view was carried out. Accordingly, the best system was proposed for use in order to achieve the highest power production and the least environmental damage.
