Modeling of optimal sorbents for hydrogen, natural gas and green house gases

par Sébastien LAYSSAC - publié le

Practical implementation of hydrogen fuel in automotive applications is still impeded by the lack of efficient, economical, light and save storage medium. Even the best candidates, nanoporous activated carbons, hardly meet the targets based on the requirement of 500 km vehicle autonomy and operating pressure below 100 bar at ambient temperatures. Although the specific surface area accessible for hydrogen may be considerably increased by adequate engineering of nanospace, the low heat of hydrogen physisorption on graphite still prevents high storage to be achieved.
