This chapter, which breaks down hydrogen’s entire value chain into three parts—production, storage, and transportation—focuses on the energy carrier’s adaptability as a zero-carbon fuel. From traditional steam-methane reforming to new electro-, photo-, and thermochemical water-splitting methods, ten production approaches are benchmarked with an emphasis on their scalability, energy efficiency, and carbon footprints. Then, in order to emphasize safety, volumetric density, and cost trade-offs, storage alternatives are evaluated across physical (compressed, liquefied), chemical (ammonia, LOHCs), and materials-based (metal hydrides, porous adsorbents) approaches. The chapter concludes with a review of carrier-conversion routes, pipeline transportation, and cryogenic tankers, highlighting infrastructural and regulatory issues. Readers can assess hydrogen’s technological and financial viability for widespread use in sustainable energy systems thanks to the succinct synthesis.
