The Role of Green Hydrogen in Achieving Low and Net-Zero Carbon Emissions: Climate Change and Global Warming

This chapter addresses and reviews the definition and role of green hydrogen (GH2) in transitioning to climate-neutral economies. It also determines the main challenges and barriers to reaching a low-net-zero emission platform by GH2 and its advantages as an economically sustainable energy resource. In the following, the role of taxes and penalties on available technologies is surveyed to answer how they can lead to a low-net-zero emission concept. Deep discussions on its future roadmap for carbon neutrality and the utilizing technologies such as carbon capture, utilization, and storage (CCUS) to help reach zero emission concept; while focusing on enriching the production of GH2 and a way for remarkable production of it to increase availability and reduce the price are other aspects that are brought up. Another aspect of this study is passing through various types of H2 to GH2. Additionally, further concerns and issues are examined in this chapter.
