Methane hydrate nucleation and growth in porous model carbon materials illuminates the way towards the design of an optimized solid based methane storage technology. High pressure methane adsorption studies on pre humidified carbons with well defined and uniform porosity show that methane hydrate formation in confined nanospace can take place at relatively low pressures, even below 3 MPa CH4, depending on the pore size and the adsorption temperature. The methane hydrate nucleation and growth is highly promoted at temperatures below the water freezing point, due to the lower activation energy in ice vs. liquid water. The methane storage capacity via hydrate formation increases with an increase in the pore size up to an optimum value for the 25 nm pore size model carbon, with a 173 improvement in the adsorption capacity as compared to the dry sample. Synchrotron X ray powder diffraction measurements SXRPD confirm the formation of methane hydrates with a sI structure, in close agreement with natural hydrates. Furthermore, SXRPD data anticipate a certain contraction of the unit cell parameter for methane hydrates grown in small pores |
