Gas hydrates have received considerable attention in the last decades due to their extensive natural occurrence on Earth and extraterrestrial bodies, and to their significant applications in sustainable technologies. In particular, hydrogen hydrates offer carbon-free high energy content per unit mass (~14 MJ·kg-1). They are promising functional materials for clean energy storage and offer alternative to the current cryo-compressed hydrogen storage technology, insuring low production and operational costs, environmentally benign nature, and lower risk of flammability. In this proposal, we aim to explore the temperature and pressure stability range for a controlled hydrogen release from C2 (H2O·H2) and C3 (H2O·2H2) hydrogen-filled ices.
