Project summary description:
Hydrogen has a major role to play in the transition to a clean, secure energy future, and Australia has the potential to become a key global player in clean hydrogen technology. While Australia is already in a position to produce hydrogen at a commercial scale, it is a highly flammable gas and can cause fires and explosions if not handled properly.

This project plays a critical, but often overlooked, role in transforming Australia’s hydrogen plan, by accurately and scientifically characterising hazard impacts on infrastructure due to accidental hydrogen explosions.

This research will develop new fundamental knowledge of hydrogen explosion characteristics to enable safe usage of hydrogen technology in vehicles, storage and transportation systems for accelerated acceptance of green hydrogen as a future energy carrier.

The outcomes will be shared with Standards Australia Committee for Hydrogen Technologies in supporting the development of national standards thus bolstering consumer confidence in the adoption of hydrogen technologies.
