The revival of a possible implementation of a hydrogen economy, both by industry and academia, spurred by the problems arising from climate change and the widespread campaign to raise awareness of environmental issues, has helped to draw attention to its immense potential. Hydrogen can bring about a fundamental and priority energy revolution for our society, bringing the flexibility and adaptability so necessary in renewable energy systems. As a clean energy carrier, hydrogen has a multitude of advantages for simultaneously de-carbonizing the transportation, residential, commercial and industrial sectors. Hydrogen has demonstrated the ability to establish strong synergies with other low-carbon alternatives, enabling a more cost-effective energy transition to de-carbonized, cleaner, environmentally non-toxic energy systems.The objective of this paper is to highlight the potential of hydrogen, starting from an analysis of its first fossil competitor, natural gas, and concluding with a precise study of the economics of hydrogen.
