Domestic gas appliance review and test program

December 1st, 2021

R&D Focus Areas:
Gas networks and appliances, Safety and standards

Lead Organisation:
University of Adelaide

Future Fuels CRC


Start date:
February 2019

Projects summary description:
This project:

  • examined whether a wide range of common household appliances (Type-A) can operate safely on natural gas with a 10% hydrogen blend.
  • determined the maximum level of hydrogen that can be blended into natural gas before flash-back, ignition or other problems occur, and
  • identified potential technical appliance issues associated with natural gas blends that have higher levels of hydrogen than can be accommodated by current appliances.

The results of the testing program are of particular interest to companies that are developing pilot projects that involve the injection of hydrogen into parts of the gas distribution system.

A short summary of the project can be viewed here.
