Abstract

Amidst the global energy crisis, escalating pollution, and burgeoning population, green hydrogen emerges as a versatile solution, with the capacity for diverse production and applications, including generation from renewable sources. Its potential encompasses critical sectors such as the heavy transport industry, as well as energy storage and industrial processes, aiding in decarbonizing challenging domains. The hydrogen-based energy system consists of four main stages; production, storage, safety and utilisation. This review specifically provides a comprehensive analysis of the production stage. Recognised as one of the ten breakthrough technologies of 2021, the global green hydrogen market is growing rapidly, and is expected to reach $141.29 billion by 2033. However, the widespread utilization of green hydrogen faces impediments due to production and storage challenges. This review paper aims to provide an overview of the conventional and cutting-edge technologies like steam methane reforming (SMR), electrolysis, photoelectrochemical processes, and biological methods pertinent to hydrogen manufacturing. It further delves into recent technological advancements encompassing electrolysis, gas reforming, C-ZEROS, HYSATA, DAE, and SRBW. This review article undergoes rigorous scrutiny, linking contemporary research progress in hydrogen production routes. The discourse also sheds light on recent developments while identifying knowledge gaps for a more nuanced understanding.
