Özet

One of the most prominent issues in the transition to net zero emissions without carbon-based fuels today and in forthcoming years is the effective use of sustainable energy sources. In this current research, the pine sawdust biomass sourced innovative multigeneration plant is proposed and planned for the production of beneficial products. The newly arranged system comprises a Brayton cycle, a supercritical CO2 Brayton cycle, a multi-stages flash desalination part, a PEM component, and a hot water preparation unit that aims the generate power, hydrogen, freshwater, and hot water. The study also deals with performing thermodynamic performance modeling, sustainability index assessment, and environmental impact evaluation to determine the developed system performance. Additionally, the energetic and exergetic performance approaches are operated to separate components and the entire configuration. After that, the comparison of the different energy conversion scenarios is examined on the basis of the energetic efficiency and CO2 emission rate. The main findings specify that the developed plant can be capable of 2674 kW net power, 0.003679 kg/s of clean hydrogen, and 2.115 kg/s of distilled water. To conclude, it can be stated that the newly developed combined plant has satisfactory performance, with 44.50% energetic performance and 30.01% exergetic performance.
