Abstract
This article comprehensively reviews hydrogen-based Combined Heat and Power (CHP) systems as an ideal energy system for reducing environmental pollution and carbon emissions. Hydrogen has a heating value three times that of gasoline, and its lifecycle carbon footprint is reduced by 50% compared to traditional fuels. The advantages and characteristics of hydrogen are examined, and the technical features of functional equipment, such as internal combustion engines, gas turbines, and fuel cells, are explored for hydrogen-based CHP systems. Notably, fuel cells can achieve efficiencies of up to 90%. Furthermore, with 96% of global hydrogen production relying on traditional fossil fuels, this review summarizes traditional and emerging hydrogen production, storage, and transport methods suitable for these systems. Additionally, key challenges, including cost reduction, infrastructure development, and integration with renewable energy sources, are discussed to address the large-scale implementation of hydrogen-based CHP systems. This review aims to lay a foundation for improved hydrogen energy utilization, inspire researchers to design more efficient and environmentally-friendly CHP systems and offer suggestions for future development.
