Risk assessment in the framework of Blue Hydrogen

In recent years, the global concentration of carbon dioxide in the atmosphere has increased drastically due to the continuous consumption of fossil fuels. With the aim of curbing climate change and meeting the increasingly stringent net-zero emission targets, blue hydrogen technology may be seen as the short-term decarbonization strategy in the prolonged period of the energy transition. In this context, the climate mitigation potential of blue hydrogen technologies derives from its peculiarity of coupling steam methane reforming (SMR) in existing plants with carbon dioxide capture and sequestration (CCS) technique. The potential introduction of this new technology in civil and industrial applications implies the presence of unexplored safety aspects that are fundamental for its effective implementation. For this reason, the present research project aims at developing a consistent quantitative risk assessment (QRA) methodology and a thorough evaluation of the safety associated with systems for blue hydrogen production.

Structure and dynamics in hydrogen-rich alloys for hydrogen storage

Renewable energy solutions that could potentially replace fossil fuels in near future is at global interest. Hydrogen as the storage media for renewable energy have increasingly come into industrial focus due to its abundance, high energy efficiency and potential fossil free production. But due to its extremely light weight and low density at normal conditions, storage and transportation is a challenge. Henceforth, search for new storage technologies is of an immense importance to reduce the overall expense of H2 usage.

This PhD project will focus on the study of new combinations of metal alloys to capture and retrieve H2, which could generate optimal solutions for the above stated problems. The starting phase of the work will involve the use of different synthesis techniques of metal alloys (e.g., mechanochemical, arc melting) followed by in-depth study of fundamental material properties such as chemical bonding, crystallographic and electronic configurations, elemental coordination environments and oxidation states together with characterization of hydrogen dynamics using a selection of advanced characterization techniques.
