The PhysOrg article Practical on-board hydrogen storage is goal of new Argonne research project said

Solving one of the biggest problems in commercialization of fuel-cell-powered automobiles is the goal of a new $1.88 million research project on on-board hydrogen storage at the U.S. Department of Energy’s Argonne National Laboratory.
 
To be practical, researchers say, the hydrogen storage system must be able to hold enough of the fuel for a driving range of 300 miles before refilling; no current technology meets this goal within the constraints of allowable weight and volume for passenger cars.
 
The Argonne research will investigate nanostructured polymeric materials as hydrogen storage adsorbents. Developed through an earlier collaboration between Argonne and the University of Chicago, the new polymer adsorbent material has shown great promise in preliminary tests. The new project funded by DOE will seek further improvements in storage capacity and an in-depth understanding of hydrogen-polymer interactions.
 
“The successful outcome of the project will lead to a low-cost, high-capacity hydrogen storage material that can be mass-produced within the existing industrial infrastructure,” said Di-Jia Liu, Argonne scientist who is leading the research project.

Di-Jia “D. J.” Liu, Ph.D. is Chemist and Principal Investigator in the Catalysis and Energy Conversion group of the Chemical Sciences and Engineering Division, Argonne National Laboratory. He studies hydrogen storage for transportation purposes; fuel cells; and batteries, including Li-Air batteries, which may be the next generation of lithium batteries.
 
Specific research activities include leading teams in synthesis and characterization of nanostructured polymeric materials for on-board hydrogen storage application; preparing aligned carbon nanotube based membrane electrode for proton exchange membrane (PEM) fuel cell application; low-cost electrode catalysts as alternative to platinum group metals for fuel cell; studying catalytic transition state via ultrafast X-ray spectroscopy; CO2 conversion and mitigation through green chemistry; and next generation materials for Li-Air battery.
