Mitchell Park has been chosen because of its proximity to our hydrogen production facility in the Tonsley Innovation District. The area also represents a good sample of typical Australian homes.

How do I know if I'm in the project area?

Residents living in the area bounded by Alawoona Ave, the railway line, Sturt River and Sturt Road, along with a small section on the western side of Marion Road – will receive the blended 5% renewable gas. 

Residents involved in the project were first informed via a letterbox drop in July 2019. You can also see which houses are included in the map below. If you are unsure, please contact us.

No changes to gas supply or costs

If you have gas connected to your property, you are not required to do anything as part of the project, and you will not notice any difference to the quality of the gas you receive. Furthermore, the project will not directly impact on any existing arrangements you have in place with your gas retailer - the amount you pay your retailer for blended gas will be no different to the cost of 100% natural gas. We have worked with retailers to ensure this is the case.

AGN will continue to provide regular updates to the community throughout the project right through until its completion. You can make sure you don’t miss any news by registering with us for updates.

The blended 5% renewable gas is as safe as natural gas. 

Gas volume on your meter

Hydrogen has a lower heating value than natural gas, this means hydrogen carries slightly less energy for the same volume. As a result, people in this demonstration will need a slightly higher volume of blended gas to provide the same amount of energy compared to using 100% natural gas.

AGN will make a billing adjustment to ensure customers do not have to pay more than if they were using 100% natural gas.

If you have questions about your billing that haven't been answered here, contact us.

Household appliances that use gas

Your appliances will continue to work safely and reliably on blended 5% renewable gas.

The characteristics of the blended 5% renewable gas supplied as part of this project are consistent with those set out for natural gas within the Australian Standard.

Any appliances sold in Australia are subject to testing to ensure they work safely and reliably with natural gas. They are tested with varying gas compositions to account for the varying sources of natural gas supplied around Australia. One of these “limit” gas compositions already contains 13% hydrogen, and therefore all certified household gas appliances sold in Australia have undergone a range of safety tests with this level of hydrogen.

We are also undertaking our own appliance testing program in which an Australian certified laboratory tested Australian appliances with various percentages of hydrogen. Initial test results indicate that appliances will work safety and reliably with a 5% hydrogen blend.

This is consistent with literature and international projects which are supplying up to 20% hydrogen blends.

Free gas appliance efficiency audit

Did you know the South Australian Government recommends your gas appliances should be checked and serviced every two years? An audit can ensure they are running safely and efficiently to help to lower gas bills.

All Mitchell Park gas customers receiving the 5% renewable gas blend are eligible for a free Gas Appliance Efficiency Audit, valued at $200.

An audit can ensure gas cooking and heating appliances are running safely and efficiently to help to lower gas bills.

To check if you are eligible for an audit, contact the project team. Terms and conditions apply.
