Hydrogen Absorption in Fluids: An Unexplored Solution for Onboard Hydrogen Storage

摘要

Adoption of hydrogen vehicles has been advocated for decades as an ecological ideal, capable of eliminating petroleum consumption as well as tail-pipe air pollution and carbon dioxide (CO(sub 2)) from automobiles. Storing sufficient hydrogen fuel onboard still remains a great technological challenge, despite recent advances in lightweight automotive materials, hybrid-electric drivetrains and fuel cells enabling 60-100 mpg equivalent hydrogen-fueled automobiles. Future onboard hydrogen storage choices will be pivotal, with lasting strategic consequences for the eventual scale, shape, security, investment requirements, and energy intensity of the hydrogen refueling infrastructure, in addition to impacts on automotive design, cost, range, performance, and safety.
