Hydrogen Production and Use: An Overview of its Importance in Mitigating Climate Change and its Nexus with Renewable and Power Engineering

Using hydrogen as a substitute for traditional fossil fuels has gained considerable attention as it can be used in various sectors, such as transportation, heating, and electricity production. This paper thoroughly examines the significance of hydrogen in addressing climate change. It will emphasize the association between renewable energy, power engineering, and hydrogen production and utilization. Hydrogen can be produced from renewable and non-renewable sources, like natural gas, solar, and wind power. This versatility positions hydrogen to play an essential role in transitioning to a low-carbon economy and mitigating the effects of climate change. The paper will highlight the advantages of hydrogen over traditional fossil fuels, such as its lower carbon emissions and the potential to reduce reliance on imported oil. Moreover, it will explore various industries where hydrogen can be utilized, like transportation, heating, and electricity production. Additionally, the paper will investigate the potential barriers to the widespread use of hydrogen, including technological, economic, policy, and regulatory challenges. The ultimate goal of this paper is to offer a comprehensive overview of hydrogen's potential to combat climate change, its relationship with renewable energy and power engineering, and the potential roadblocks in its implementation.
