As global concerns about fossil fuel depletion and environmental issues escalate, the search for alternative energy sources intensifies. Hydrogen fuel has emerged as a promising solution due to its renewable nature and zero emissions during combustion, making it a key player in sustainable energy systems. Its diverse applications range from electricity generation to cleaner transportation systems, with examples like Hydrogen-enriched Compressed Natural Gas (HCNG) proving to enhance performance and decrease emissions in internal combustion engines. The unique characteristics of hydrogen, such as its efficiency in lean combustion conditions and carbon-free nature, make it an attractive option for cleaner and more efficient engine operation. Various methods like Steam Methane Reforming (SMR) are currently viable for hydrogen production, with SMR being favored for its efficiency, low cost, and eco-friendly attributes. However, as renewable hydrogen technologies become more competitive, cleaner processes are expected to replace SMR in the future. Research efforts have focused on improving SMR efficiency through studies on reactor design, operating parameters, and waste heat recovery. The increasing viability of hydrogen as an effective and clean energy source is gaining recognition in academic and industrial circles, emphasizing the need for further exploration of its potential across different sectors.
