Hydrogen: technologies, policies and strategies

This thesis, entitled "Hydrogen: Technologies, Policies and Strategies", examines the pivotal role of green hydrogen in the transition to sustainable energy systems. It emphasises the necessity of addressing climate change and the potential of hydrogen as a clean energy carrier. The work examines the various forms of hydrogen, outlining the processes involved in its production, including electrolysis and storage, as well as its transportation. It also analyses the policies at the national and international levels that influence the development of the hydrogen industry, with a focus on the United States and the European Union. Furthermore, the thesis assesses Italy's strategy for green hydrogen, evaluating ongoing projects and the National Integrated Energy and Climate Plan (PNIEC) to assess its targets and initiatives.
