This chapter focuses on the transformative potential of hydrogen (H2) as a crucial component for meeting global energy needs by 2050, with a focus on transitioning from gray H2 to sustainable green and blue H2 integrated with carbon capture and storage (CCS). It projects a significant rise in H2 demand to 530 million tonnes (Mt) to achieve net-zero carbon emissions, highlighting H2 essential role in global energy strategies. The chapter also explores the rapid growth of water (H2O) electrolysis, particularly emphasizing the increased efficiency and adaptability of proton exchange membrane electrolyzers.
