AGN owns the natural gas distribution network in Gladstone, which energy retailers use our network to transport gas to homes and businesses.

Hydrogen Park Gladstone in Queensland is the next step on our renewable gas journey and our builds on our Hydrogen Park South Australia facility to deliver the first ‘whole of gas network’ decarbonisation project.

The $4.2 million electrolyser facility will produce renewable hydrogen, using water and renewable electricity, for blending at up to 10%with natural gas, and supply to the entire Gladstone network of over 750 properties. It will be located at Derby Street, South Gladstone, with production beginning in 2022, and supply the highest volume of hydrogen delivered by an existing gas network and includes the first project to supply a commercial and industrial properties.

Supported by the Queensland Government with grant funding of more than $1.7 million, HyP Gladstone aligns with the State’s Hydrogen Strategy, supporting Gladstone’s vision to be a key hub for Queensland’s hydrogen industry as it is for natural gas today.

We are currently in the development stage of the project, including securing the site, lodging Development Applications, and appointing project partners. Site work is expected to commence in the second quarter of 2022, with first blended gas supplied to customers by September 2022

How is renewable hydrogen produced?

Hydrogen is the most abundant molecule in the universe, however it’s not freely available - it must be separated from other elements.

HyP Gladstone’s renewable hydrogen will be is created from water and renewable electricity in a process called electrolysis, and supplied to nearby homes and businesses through the existing gas networks. We are also investigating using the facility to decarbonise transport through a refuelling station as well as potential for industrial and power generation supply.

What’s next – the longer-term vision

At AGN we are committed to delivering for our customers today and tomorrow. We are targeting 10% renewable gas across our networks by 2030 and conversion to 100% renewable gas by no later than 2050 – and by 2040 as our stretch target. You can learn more about our plans here.

Renewable gas is not only key to decarbonise homes and businesses but can also be used in vehicles, industry and as a way to export our sun and wind resources.

We are actively pursuing additional hydrogen projects with a view to blending more hydrogen into our Queensland and other Australian networks.


Project Benefits


Australia is working towards a reduction in carbon dioxide (CO2) to between 26 to 28% below 2005 levels by 2030 and Queensland is working towards 50% renewable energy by 2030 and net zero carbon emissions by 2050. It also has ambitions for a sustainable renewable hydrogen industry as supported by Queensland’s Hydrogen Industry Development Strategy 2019-2024.

Benefits of hydrogen and blended 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. As we move towards net zero emissions, maintaining diverse sources of energy can help with energy security, reliability and affordability.

Unlike natural gas or petrol, when hydrogen is burned there are no CO2 emissions. Just like natural gas, hydrogen can be used for:

  • cooking
  • hot water
  • heating buildings
  • powering vehicles
  • generating electricity


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. It also means customers retain their choice of energy supply, and those industries relying on gas can continue to access it.

Hydrogen also has other benefits such as:

  • being used as a transport fuel
  • providing a way to store renewable electricity
  • being able to generate renewable electricity through fuel cells and turbines
  • being a desirable product overseas, enabling a new export industry


How much difference will hydrogen blending make to emissions?

This 10% renewable hydrogen blend in Gladstone is the next step to lowering carbon emissions. A blend of up to 10% renewable hydrogen helps to lower carbon emissions relatively quickly without changes to appliances, pipes and meters. This can happen while larger scale, 100% conversion projects are being progressed.

What it means for homes and businesses


Residents and businesses connected to the gas distribution network in Gladstone Central, Barney Point, South Gladstone and West Gladstone will receive the 10% renewable gas blend. These properties are referred to as the blended gas project area, shown on this map.

If you are the blended gas project area and connected to the natural gas network, you are not required to do anything as part of the project. You will not notice any difference to the quality of the gas you receive.

Furthermore, the project will not impact any existing arrangements you have in place with your gas retailer - the amount you pay for blended gas will be no different to the cost of 100% natural gas.

If you are live or work in the project area and you either do not have natural gas or you have an LPG connection, this information is provided to you for information only.

Homes and businesses in the blended gas project area were first informed via a letterbox drop in August 2021. If you are unsure how this project applies to you, please contact us.


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 natural gas. AGN will make a billing adjustment to ensure customers do not have to pay more than if they were using natural gas. If you have questions about your billing that haven't been answered here, contact us.


No impact on network or appliances

Our networks are made of polyethylene and are suitable for transporting a hydrogen blended gas.

Your appliances will continue to work safely and reliably on blended 10% renewable gas. You can see a video of someone using blended renewable gas here.

The characteristics of the blended 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.

There has been extensive research and several projects in Australia and overseas in relation to the blending of hydrogen with natural gas and its use in appliances.

  • At Mitchell Park in South Australia we are delivering a 5% renewable gas blend to customers
  • Jemena’s Western Sydney Green Gas project will begin blending renewable gas to customers in the second half of 2021
  • Projects in the Netherlands, UK and France are using hydrogen at up to 20% volume for hundreds of customers
  • a project in Germany has successfully blended up to 10% hydrogen volume


"Hydrogen can be safely added to natural gas supplies at 10% by volume without changes to pipelines, appliances or regulations. Over time, and with modifications to the existing gas networks and appliances, hydrogen can completely replace natural gas for domestic cooking, heating and hot water." A report for the Council of Australian Governments (COAG)

As a benefit of being part of this project, we are offering residents in the demonstration area an opportunity to have a free gas appliance audit to ensure your gas appliances are installed correctly and working safely and efficiently. Contact us to register your interest in the appliance audit.

Regulations and approvals

We are experts in developing and operating gas infrastructure safely and reliably. This is our commitment to the more than one million Australians we serve. Our commitment to safety underpins everything we do, and we are satisfied that this 10% renewable hydrogen blend with natural gas is as safe as 100% natural gas. This is based on:

  • our experience and the approvals process we have gone through to date
  • that the characteristics of the blended renewable gas will continue to be consistent with those set out for natural gas within the Australian Standard
  • our other projects – including Hydrogen Park South Australia
  • the extensive literature and research undertaken
  • recent testing of Australian appliances
  • the results of international projects which are already blending up to 20% hydrogen

At AGN we’re subject to regulation by government bodies, which are designed to ensure our commitment to safety, reliability and service continue. We will have all necessary approvals to undertake this project before first production.

Using hydrogen and natural gas safely

Hydrogen, like other fuels, is flammable and this is a key reason it can provide us with energy. It also means we need to treat hydrogen and blended gas with respect, as we do natural gas, electricity, petrol and other energy carriers.

Blending 10% renewable hydrogen won’t change the approach to safety that is currently in place. The blended renewable gas will still retain the distinctive natural gas smell that allows you to detect any leak.

You should continue to follow the same safety principles you do with your natural gas supply, ensuring you appliances are installed correctly and maintained. Importantly, if you ever smell gas or think there is a leak, you should report it.

Did You Know? ... We are going back to the future!

From the late 1960s through to the 1990s parts of Queensland relied on Towns Gas. Towns Gas was gas manufactured from coal and consisted of 50-60% hydrogen. Some places such as Hong Kong and Singapore still rely on Town Gas. We switched from Town Gas upon the discovery of natural gas, because at the time natural gas was considered more reliable and economic. Today, the costs of producing hydrogen are coming down, and we know that blended gas is the first step on our journey to lowering carbon emissions.


Reporting a gas leak

If you ever smell gas in the street or on your property before or including your gas meter you should call our Leaks and Emergency Services on 1800 GAS LEAK (1800 427 532) to locate and repair the leak.

If you think the leak is after the meter on a section of pipe work connecting your appliances, or on the appliance itself, you should contact a licensed gas fitter to fix the problem. Remember, any person undertaking work involving gas must be appropriately licensed.

Electrolyser Purchased

August 2020

After executing its Funding Agreement with the Queensland Government in mid-2020, we ordered a Nel 175 kilowatt Proton Exchange Membrane (PEM) electrolyser for installation at HyP Gladstone. The electrolyser is a key component of the electrolysis process, which uses renewable electricity to split water into oxygen and hydrogen gas, producing approximately 60kg of hydrogen per day.

The renewable hydrogen will then be blended with natural gas for injection into AGN's Gladstone natural gas networks. This model electrolyser unit is one of several currently operating in Australia, including in the Australian Capital Territory and Western Australia.


Project Funding Announced

February 2020

HyP Gladstone was announced as the first grant recipient from the Queensland Government’s $15 million Hydrogen Industry Development Fund. Premier and Minister for Trade Annastacia Palaszczuk said in an Australian-first, Gladstone will become the first entire city in the nation to be on a blend of natural gas and hydrogen.

“Using renewable hydrogen, Australian Gas Networks (AGN) will trial the blended hydrogen gas with a view to converting Gladstone’s network to hydrogen in the future,” Premier Palaszczuk said. “The Queensland Government is working hard to drive the hydrogen industry forward, to create highly skilled jobs, especially in regional Queensland.”

AGN’s Chief Executive Officer, Mr Ben Wilson said AGIG is proud to partner with the Queensland Government on this ground-breaking project. “This project supports Gladstone’s vision to be a key hub for Queensland’s domestic and hydrogen export industry, just as it is for natural gas today."
