SUMMARY: A huge obstacle to replacing gasoline as the main energy carrier in automotive applications is the relatively low energy density of suitable replacements. Gaseous energy carriers must be stored at high pressure or very low temperature in order to obtain an energy density suitable for vehicular use. High pressure gas storage requires large, cylindrical containers that occupy large amou…
Due to its clean combustion and high heating value, hydrogen is under consideration as a replacement for fossil fuels in mobile applications. To achieve this goal, however, an effective means of on-board storage is required, prompting the U.S. Department of Energy to set 2010 storage system performance targets of 6.0 wt % H2 and 45 g H2/L. Recent work has exposed the considerable potential for…
