Abstract
This study establishes an innovative multigeneration system integrating biomass digestion, solar thermal collection, Brayton and Rankine cycles, and hydrogen production technologies for sustainable energy production. The comprehensive system simultaneously delivers electricity, heating, cooling, and hydrogen with exceptional efficiency. Thermodynamic analysis reveals the Brayton cycle, Steam Rankine cycle, and hydrogen liquefaction systems achieve energy efficiencies of 40 %, 41 %, and 65 % respectively, with corresponding exergy efficiencies of 51 %, 68 %, and 12 %. The complete integrated system demonstrates overall energy and exergy efficiencies of 45.52 % and 66.85 %. Financial assessment indicates robust economic viability with projected profitability by 2031 and a net present value of $7.70 million. Environmental analysis confirms significant CO2 emission reductions compared to conventional energy systems, supporting sustainable development objectives.
期刊介绍:
The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc.
The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
