Composite Sorbents Based on Carbon Fibre “Busofit” for Hydrogen Storage and Transportation
A new hydrogen storage and transportation system based on composite sorbent application (metal-hydride particles on the fibre) was suggested and tested. This new design of the sorbent bed with heat pipe thermal control is capable to enhance thermodynamic efficiency of the gas storage vessels and increase its sorption capacity. The inexpensive microporous carbon obtained by thermal treatment of raw material (wood, sawdust, cellulose, straw, paper for recycling, peat etc.) after impregnation is especially attractive. In this way a number of perspective sorbents were suggested in Belarus: the activated carbon fiber “Busofi-M8” (a product of pyrolysis of the impregnated cellulose) and the activated carbon obtained from waste products of wood “WAC 3-00”. The goal of this presentation is the development of the sectional vessel with heat pipe (HP) for hydrogen sorption storage at average pressures 3.5–6 MPa, every separate section of which has the case made from an aluminium (or reinforced plastics) and filled with briquettes of the sorbent material where hydrogen is situated in adsorbed and compressed states. Such vessels for hydrogen storage and transportation are interesting to be applied in fuel cells vehicle, or dual-fuel engine car (hydrogen/ gasoline, hydrogen/methane).
