FIGURE 5.5. Site density profiles of the planar liquid/vapour interface of methanol at ambient temperature, following from the SS-LMBW/RISM-KHM theory. Methyl group, oxygen and hydroxyl hydrogen sites of the methanol molecule are represented by solid, dashed and dotted lines, respectively. The density profiles are normalized to the side densities in the liquid phase, pa . The lower part zooms in the interface structure. 

Moreover, hydrogen storage onboard vehicles and ships remains in pressurised tanks. An alternative solution seems to be needed, which may be the liquid hydrogen tank developed by Air Liquide for the Renault fuel cell. See the listed Renault web site for the Renault/du Vera vehicle fuel cell project. 

Pressurised cylinders are the usual mobile hydrogen store, albeit much effort is being expended on alternatives see the Renault/du Vera/Scenic web site, and the Air Liquide development of a liquid hydrogen tank.
