Hydrogen is an energy vector which should be extensively used in the future. Storing energy by generating hydrogen during electricity production peaks might be a complementary alternative to the establishment of regulated energy networks like Smartgrids. For this reason it is necessary to improve storage systems by developing new materials for solid-state hydrogen storage. The present study focuses on hydrogen adsorption on activated carbons produced by activation of hydrochars with potassium hydroxide (KOH). These hydrochars were produced by submitting sucrose solutions to hydrothermal carbonisation (HTC). The aim of the present study was to get insight into the effect of both the initial sucrose concentration and the activation ratio on the textural properties of the resultant activated carbons (ACs), and hence on their hydrogen storage performances.
