Green hydrogen is widely recognized as a future energy carrier due to its non-polluting properties and high energy density. To realize hydrogen mobility in the future, it is essential to build a complete green hydrogen supply chain that can make it a key energy carrier for vehicles. This paper reviews the green hydrogen supply chain, including production, storage, transport and utilization technologies. Special attention is paid to the different ways of transporting hydrogen. The challenges in building a hydrogen supply chain from a technical-economic, social and political point of view and the prospects for its future development are discussed. It also examines the possibilities of assessing the potential demand for green hydrogen and reviews the stages of its entry into the market as an alternative fuel. Factors that would stimulate demand are indicated. Finally, a look is turned to Bulgaria`s attempts to stimulate the production of green hydrogen and its use in mobility. The country`s main commitments regarding hydrogen mobility and plans for the development of hydrogen urban transport are reviewed.
