Hydrogen energy is a great source of clean energy. Hydrogen is readily available, there are no harmful emissions, it's environmentally friendly, non-toxic and renewable. However, as hydrogen is volatile in its gas or liquid form, the storage of hydrogen is a vital part of a clean energy plan and the hydrogen economy.
UNSW Researchers have identified a nano-material and a method which overcomes typical hydrogen storage issues with high temperatures and kinetics.
Our molecular hydrogen storage technology allows for controlled, rapid uptake and storage of molecular H2 as well as voltage controlled release at moderate temperatures.

Through a computational design approach we have identified a material and a method to capture and controllably release molecular H2 which complies with all of these parameters. Our patented technology “Electrocatalytic Gas Capture” allows for controlled, rapid uptake and storage of molecular H2 as well as voltage controlled release at moderate temperatures.
Electrical charging of graphitic carbon nitride nanosheets (g-C4N3 and g-C3N4) is proposed as a strategy for high-capacity and electrocatalytically switchable hydrogen storage. In contrast to other hydrogen storage approaches, this approach promises both facile reversibility and tuneable kinetics without the need of any specific catalysts. These predictions may prove to be instrumental in searching for a new class of high-capacity hydrogen storage materials.
