A main obstacle of hydrogen-powered fuel cell vehicles (HFCV’s) has been the lack of a lightweight, safe hydrogen storage material. Tiancun Xiao and Peter P. Edwards, University of Oxford, UK, and colleagues have shown that hydrocarbon wax (paraffin wax on a carbon support (CS)) rapidly releases large amounts of hydrogen when activated with a ruthenium metal catalyst and microwaves.
Wax is a benign material that can be manufactured from sustainable processes. It will not catch fire or contaminate the environment and is safe for drivers and passengers.
