The Australian Pipelines and Gas Association (APGA) represents the owners, operators, designers, constructors and service providers of Australia’s pipeline infrastructure, connecting natural and renewable gas production to demand centres in cities and other locations across Australia. Offering a wide range of services to gas users, retailers and producers, APGA members ensure the safe and reliable delivery of 28 per cent of the end-use energy consumed in Australia and are at the forefront of Australia’s renewable gas industry, helping achieve net-zero as quickly and affordably as possible.
APGA supports a net zero emission future for Australia by 2050[1]. Renewable gases represent a real, technically viable approach to lowest-cost energy decarbonisation in Australia. APGA sees renewable gases such as hydrogen and biomethane playing a critical role in decarbonising gas use for both wholesale and retail customers.[2]
The green hydrogen and biomethane industries are gathering pace. State and Territory Governments are putting regulatory measures in place to support continued growth. However, development of a thriving renewable gases industry in Australia requires additional coordination and policy support at a national level.
In the 2023-24 Federal Budget, APGA proposes that the Federal Government make several key regulatory changes to support this transition, and also investigate ways to provide additional supply to the east coast gas market in the medium-term.
APGA would be pleased to provide additional detail on any of the enclosed proposals. To discuss any of the above feedback further, please contact National Policy Manager, Jordan McCollum, on +61 422 057 856 or jmccollum@apga.org.au.
Yours sincerely,

The development of an Australian renewable gas supply chain, operating alongside Australia’s renewable electricity supply chain, can help optimise Australia’s renewable energy transition.
‘Green’ hydrogen and biomethane do not contribute carbon emissions when consumed. In the case of biomethane, no modifications of infrastructure or supply chains are required as it is chemically indistinguishable from natural gas; hydrogen behaves similarly, requiring some modification to supply chains and customer appliances.
Research on renewable gas supply chain components in Australia indicates that renewable gas supply chains are likely cost-competitive with renewable electricity supply chains in a net zero energy future. This possibility was first indicated in the 2018 Frontier Economics report The benefits of gas infrastructure to decarbonise Australia. [3] A recent APGA study strengthens this indication for total customer cost of renewable gas use in the home, indicating cost competitiveness with renewable electricity for household decarbonisation[4].
This is possible in part due to the fact that pipelines provide lower cost energy transport and storage in comparison to powerlines and other forms of electricity energy storage.[5] Pipelines are considerably cheaper than powerlines to build, and existing pipelines can be repurposed to carry hydrogen or hydrogen blends (no modification is required for biomethane). This means that renewable gas supply chains could be more economically efficient than renewable electricity.[6],[7] Gas infrastructure already delivers more energy at lower cost, lower emissions intensity and greater reliability in Victoria than its electricity infrastructure.[8]
Particularly in the case of green hydrogen, Federal Government support is needed to help overcome some of the remaining barriers to market entry, including investment certainty and consumer confidence. To build upon existing Federal Government activities in renewable gases, APGA recommends the Federal Government support parallel renewable energy pathways in renewable electricity and renewable gases, and ensure existing emissions frameworks do not disincentivise the contribution of renewable gases. APGA proposes that the Federal Government has the opportunity to achieve this end through measures that:
To support investment in renewable gas production, renewable gas customers need to be able to access the zero scope 1 emission value proposition of renewable gas consumption. Current federal policy and regulation impedes this. Funding for the following initiatives is proposed to enable renewable gas customers to access the zero scope 1 emission value proposition of renewable gas consumption.
The lowest possible cost of gas for renewable gas customers will be achieved through developing efficient, multi-user renewable gas pipeline infrastructure. However, neither CSIRO or AEMO have a gas system model at the level of fidelity as electricity modelling, and the National Gas Law disincentivises development of new common user infrastructure. Testing for which existing pipelines can be repurposed for hydrogen is also a costly task. Funding of the following initiatives is proposed to deliver a least cost renewable gas system for Australia.
In December 2022 the Federal Government passed the Competition and Consumer Amendment (Gas Prices) Bill 2022. As part of this, the Greens and the Federal Government agreed to develop the Household and Business Electrification Package, to be presented at the 2023-24 Federal Budget.
While we have not seen the details of this package, we understand it will include support that could be provided to households and businesses (particularly small businesses) to electrify their space heating, water heating, cooking and other appliances and equipment, and will focus on households that most need support, such as low-income households, renters, public and community housing residents and apartment dwellers.
This package appears to conclude that electrification of gas demand is the only option for households and small businesses. However new research is starting to indicate that renewable gases could be cost competitive with renewable electricity when decarbonising gas use in the home.[9] APGA and its members believe that all avenues to decarbonisation should be explored and supported equally; pursuing electrification in all instances, as this mooted package appears, is a missed opportunity to take advantage of the significant opportunities of renewable gas.
Instead of one package focused on electrification as the singular pathway to decarbonisation, APGA proposes that the package be expanded to a Business and Household Decarbonisation Package, which is agnostic to the specific technologies and will support residential and commercial gas consumers who do not wish to or are unable to electrify. This package could be used to incentivise investment in developing high-efficiency, hydrogen-ready gas appliances, and would dovetail with existing efforts to support the emerging commercial-scale renewable hydrogen and renewable methane industries.
When Liquefied Natural Gas (LNG) terminals in Queensland became operational in the middle of last decade, the east coast gas market went from being “long” in supply (where the domestic production capacity was greater than the domestic demand capacity) to being “short” in supply (where the domestic production capacity was less than the domestic and export demand capacity). As a result of this, the east coast gas market became more sensitive to high gas price shocks while also becoming exposed to international LNG export prices.
In long supply markets, customers set prices relative to producer costs, while in short supply markets, the producers set prices relative to the highest-paying customer. This has contributed to the significant rises in prices experienced by consumers in the east coast gas market. Across the past decade, APGA has warned of the risk posed to customers by a short supply gas market, forewarning exposure to price shocks should international energy prices rise.
The Reserve Bank of Australia concluded in early 2021 that without additional supply, “contracted gas prices on the east coast are likely to remain structurally higher than their pre-2015 levels over the coming decade, reflecting higher marginal costs of domestic production.” [10] In 2022 the Federal Department of Industry, Science and Resources noted that the tightening supply-demand balance has left the east coast gas market increasingly sensitive to external shocks like Russia’s unjust war in Ukraine; the associated supply-constrained international market has led to large increases in domestic spot gas prices.[11]
Energy Ministers have decided to temporarily cap gas prices and provide the Australian Energy Market Operator additional powers in order to address the current natural gas price issues in the short-term. However, a medium-term solution is also required which returns the east coast gas market to being long in supply in order to protect energy customers from a repeat of the current scenario. Investment is required to deliver the additional supply necessary to exceed demand and decouple the east coast gas market from international prices.
APGA believes there is opportunity for renewable gas production to be a significant part of this supply uplift. A proposed new CSIRO gas model in the previous section would also contribute to this work.
The decarbonisation of Australia’s private and commercial vehicle fleet is an important part of reducing overall transport sector emissions. While electrification is well underway, the opportunity for hydrogen to provide a complementary supply chain has yet to be fully explored. APGA believes hydrogen electric vehicles can play a valuable role in the future of long-distance haulage and private vehicles in rural areas.[12] Hydrogen electric vehicles have considerable use cases, as they are lighter in weight, have greater range and faster refuelling capabilities than equivalent battery electric vehicles.
Both electricity transmission and hydrogen pipeline infrastructure can be used to support development of battery EVs and FCEV refuelling. Optimised refuelling infrastructure will support least cost vehicle decarbonisation for Australia but will require guidance to enable common user infrastructure.
