Hydrogen, a promising energy carrier, is expected to play a pivotal role in the transition toward sustainable energy systems. This chapter explores the current technologies, profitability, and future potential of hydrogen applications, particularly in distribution systems. The fundamental properties of hydrogen, including its significance in various energy sectors, are discussed. The various methods of hydrogen production, such as from natural gas, coal, and biomass, and by electrolysis, are examined, alongside a comparative analysis of the technologies involved. Operation of electrolyzers can provide additional flexibility in distributions systems. The chapter also investigates hydrogen storage and transport solutions, which are critical for its practical deployment. Storage options such as tank-based, fuel-based, and geological storage are evaluated, with a particular focus on cost-effectiveness and scalability. The different modes of hydrogen transport, including pipelines, ships, and trucks, are assessed in terms of efficiency, infrastructure requirements, and associated costs. The comparison of transport costs provides valuable insights into the economic feasibility of hydrogen distribution at large scales. The utilization of hydrogen in fuel cells, which have significant potential for both stationary and mobile power generation, is explored in depth, as well as its applications in heating and industrial sectors. The chapter concludes by providing a comprehensive overview of hydrogen’s role in future energy distribution systems, highlighting its challenges and opportunities for widespread adoption in a decarbonized economy.
