The goal is to investigate the feasibility to use a local biomass (Posidonia Oceanica and Wood chips), as a raw precursor, to the production of activated carbons (AC) with a high surface area and remarkable hydrogen (H2) adsorption properties. Biomasses (particle size of 0.3e0.4 mm) were pyrolyzed at 600 C with a heating rate of 5 C/min under an argon atmosphere. The biochar obtained from the carbonization step was chemically activated with KOH. The activation methodology induces a considerable improvement of the properties of the porous carbon in terms of carbon content (from 58 to 69 wt% to 93e96 wt%), surface area (from 41 to 425 m2/g to 2810e2835 m2/g) and H2 adsorption in cryogenic condition (from 0,1 wt% to over 5 wt%).
