We explores the global demand for sustainable power and the specific roles hydrogen production methods will play in meeting those needs. It distinguishes between green hydrogen, which is generated by splitting water using renewable electricity, and blue hydrogen, which is derived from fossil fuels paired with carbon sequestration. While green energy offers a zero-emission profile, it requires extensive infrastructure development, whereas blue energy utilizes existing systems but depends on evolving storage technologies. We suggest that a hybrid approach incorporating both methods is likely necessary to achieve a low-carbon future. Ultimately, the choice between these technologies will define the global energy landscape and the pace of environmental restoration.
