Amid a global climate crisis, more frequent and intense heat waves alter people's quality of life and increase morbidity and mortality. Cities are particularly vulnerable to heat because they concentrate people, including many in situations of individual, social and/or environmental fragility, and because the urban fabric, structure, cover and metabolism alter the thermal environment, which generally exacerbates heat stress. Creating cities that sustainably and effectively address the challenge of overheating is thus of utmost importance.

The HYperStock project aims at consolidating the French scientific leadership in the field of storage and distribution of hydrogen under high pressure. This is an essential element of the hydrogen value chain on which the research and innovation effort must focus, specifically with an aim at decarbonizing heavy transportation mobility, in order to build up the green and autonomous hydrogen economy of tomorrow.
