Frequently asked questions

Renewable gas is a term used to describe gases that do not produce any additional carbon emissions in their production and use.

Common forms of renewable gas include hydrogen and biomethane which can be used in the same way as natural gas is today.

The appliances sold in Australia are designed to operate efficiently and effectively with natural gas. They are tested with varying gas compositions to account for the varying sources of natural gas supplied around Australia. One such “limit” gas 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.

Consistent with this and with our own appliance testing program, we are confident that your existing home appliances will work safely, reliably and effectively with up to 10% hydrogen blends and potentially even higher – with international projects supplying up to 20% hydrogen blends.

When receiving 100% renewable hydrogen gas, new appliances or burner parts may be required.

100% hydrogen appliances are in use throughout Australia and the world today, but at the moment they are niche product whilst the market establishes itself. Appliance manufacturers are already working on hydrogen ready appliances that will easily transition from natural gas to hydrogen gas.

We plan to supply 10% renewable gas by 2030 before starting the conversion to 100% renewable gas. The timing of 100% conversion (post 2030) is aligned with when many appliances will be able to be replaced as part of their natural retirement cycle which will also contribute to a smooth transition.

You can still connect to the gas network if you’re building or renovating.

On average there are approximately 100,000 new gas connections across Australia every year. Connecting to the gas network today provides you the benefits of natural gas – safe, reliable, controllable energy – and a pathway to renewable gas in the near future.

By 2025, 100% renewable gas will be available for selected new home estates.

We understand that price is very important to our customers.

For you, gas prices won’t change anytime soon – we’re absorbing the costs for now.

At the moment producing renewable gas is a new industry in Australia and is more expensive than natural gas.

Just like solar, wind and battery power, in order to drive down costs we need to develop projects and increase scale. We are doing this with the support of Governments, who are providing project funding in order to ensure customers do not bear added costs. Consistent with this, customers receiving blended renewable gas as part of our Hydrogen Park South Australia and Hydrogen Park Gladstone projects will pay no more than if they were receiving 100% natural gas.

Our modelling indicates that renewable hydrogen and biomethane can be produced at prices equivalent to natural gas by 2030 if not before. This is consistent with the Federal Government targets of “H2 under $2 per kg”. At this time we will look to begin conversion of our networks to 100% renewable gas.

Today Australia’s energy system relies on diverse sources of energy – natural gas and liquid fuels (petrol and diesel) are used for more than double the energy provided by electricity. It’s important that as we move towards net zero emissions we continue to use diverse sources of energy – if we don’t maintain diversity we risk developing a more costly and less reliable energy system overall. Importantly modelling indicates that decarbonising natural gas through renewable hydrogen can be up to 50% cheaper than electrification as it avoids significant investment in additional electricity infrastructure such as poles, wires and additional batteries.

You do not need to do anything. We are working with industry and governments across Australia to deliver the renewable gas future.

To start we are delivering demonstration projects. Hydrogen Park South Australia commenced in May 2021 and is delivering volumes of up to 5% renewable hydrogen to more than 700 homes in the nearby suburb of Mitchell Park, while Hydrogen Park Gladstone is currently being developed and will deliver up to a 10% renewable hydrogen blend to the Gladstone gas distribution network in Queensland in 2022.

We will then move to large scale blending as we target 10% renewable gas across our networks by 2030, this includes through Hydrogen Park Murray Valley which was recently awarded funding by the Australian Renewable Energy Agency and will deliver up to a 10% renewable hydrogen blend to more than 40,000 customers in Wodonga and Albury.

From 2025 we want to be able to offer new housing developments a 100% renewable gas product, before conversion of our existing networks from 10% to 100% renewable gas begins from 2030. At this point a change to hydrogen appliances may be required, we are working with appliance manufacturers to make sure this occurs as smoothly as possible.

Renewable gas is already being delivered to some parts of Australia, with more to come in the near future.

See our timeline for more.

For business and industrial customers you can be confident that your connection to the gas network will provide you with the energy you require and also help you transition to a low carbon future.

Our current plans are to blend volumes of up to 10% renewable hydrogen by 2030. Beyond 2030 we will look to convert to 100% renewable gas, which may require some change to appliances, work is already underway with the appliance sector to make this transition as smooth as possible.

We are committed to engaging with the community. When renewable gas projects are developed in your area we will let you know well in advance to ensure any questions you may have are answered.
