Effective, cheap and safe hydrogen storage technologies are critical to underpinning the success of the energy carrier. Typically, hydrogen is stored in its gaseous form, in high-pressure cylinders, supercooled into its liquid form or stored as chemical hydride.
Although progress continues to see those storage techniques become cheaper, critics say that storage remains one of the most significant barriers standing in the way of hydrogen’s widespread use.
In September, however, a team of researchers at ETH Zürich University in Switzerland conducted the successful demonstration of a new hydrogen storage approach slated to be safer and more cost-effective than established technologies.
