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.

With a worldwide production of nearly 380 million tons per year, polymer materials play a central role in our modern society. They are used in the manufacture of innumerable daily-life products, or as more sophisticated compounds in medicine, diagnostics, and fine chemistry. However, economical and new societal constraints require a more rational design and alternative synthesis, formulation and processing methods for polymer manufacturing to meet the need for greater sustainability, more virtuous end-of-life management, while maintaining optimal performances in application.

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.
