Researchers from the University of Melbourne have developed new operating thresholds for safe and cost-effective biogas production, aiding Australia’s shift to renewable natural gas and integrating it into existing networks amidst industry expansion.
Researchers at the University of Melbourne say they have identified the operating thresholds that could help Australian utilities and waste firms turn organic residues into biomethane more safely and cheaply, a development that could make renewable gas easier to feed into existing networks. The work, led by Professor Mohsen Talei, fed into the latest revision of Australian Standards, which now treat biomethane as a natural-gas equivalent and set fresh contaminant limits for producers and network operators.

Biomethane, also known as renewable natural gas, is produced when micro-organisms break down food waste, sewage and animal waste in oxygen-free tanks before the resulting biogas is upgraded to near-pure methane. The University of Melbourne team said the revised standards create a common technical base for distributors, manufacturers and regulators, which should help remove one of the biggest barriers to scaling the fuel commercially.

The timing matters for Australia’s gas sector. ARENA says the Malabar Biomethane Injection Project in Sydney is the country’s first biomethane-to-gas-network injection facility at scale, and that it can supply about 6,300 homes a year with potential to expand to 200 terajoules annually. Jemena says the plant, built with Sydney Water and backed by ARENA funding, upgrades biogas from wastewater treatment to meet Australian Standard AS4564:2020 and injects it into the New South Wales network.

For industrial decarbonisation advocates, the attraction is obvious: biomethane can be used in existing boilers, engines and gas networks without the infrastructure overhaul associated with many other low-carbon fuels. ARENA has said upgraded biomethane is chemically comparable to fossil methane and suitable for pipeline injection, while the Malabar commissioning report highlights both the technical promise and the practical hurdles, including hydrogen sulphide risk, equipment compliance and variable biogas quality.

That technical challenge is where Talei’s research aims to add value. He said the main problem is removing siloxane, a compound found in household products, because when burned it can leave a glass-like residue that damages appliances. By combining simulation and experimental data, the team says it has built a framework for estimating how much of the contaminant can remain while equipment still runs reliably, even at levels too low to study directly in the lab. The researchers are now in talks with an industry partner about further work and wider adoption. (wastemanagementreview.com.au)

- https://arena.gov.au/knowledge-bank/jemena-gas-network-malabar-biomethane-injection-project-commissioning-report/ – This report details the commissioning phase of Australia’s first biomethane injection facility, the Malabar Biomethane Injection Project. Located adjacent to Sydney Water’s Malabar Wastewater Treatment Plant, the project upgrades biogas into biomethane and injects it into the existing New South Wales gas network. The facility supplies enough biomethane to meet the annual consumption of approximately 6,300 homes, with potential scalability up to 200 TJ/year. The report highlights technical achievements, construction learnings, and foundational insights for scaling renewable gas infrastructure in Australia.
- https://www.jemena.com.au/future-energy/future-gas/Malabar-Biomethane-Injection-Plant/ – The Malabar Biomethane Injection Plant, a collaboration between Jemena and Sydney Water, is Australia’s first facility to produce and inject biomethane into the gas distribution network. Located at the Malabar Wastewater Treatment Plant, the facility upgrades biogas produced from organic waste into high-quality biomethane, meeting Australian Standard AS4564:2020. The project is co-funded by Jemena and the Australian Renewable Energy Agency (ARENA), with an initial capacity of 95 terajoules of renewable gas per annum, equivalent to the average annual gas usage of 6,300 NSW homes.
- https://www.gpaeng.com.au/project/malabar-biomethane-project/ – GPA Engineering supported the development of Australia’s first biomethane production facility, the Malabar Biomethane Injection Plant. In partnership with Jemena and Sydney Water, the facility upgrades excess biogas produced by the Malabar Water Resource Recovery Facility into biomethane, which is then injected into Jemena’s NSW Gas Distribution Network. GPA provided a range of engineering services, including site civil design, electrical design, and process engineering, contributing to the project’s goal of reducing Australia’s carbon footprint through renewable energy.
- https://www.iscouncil.org/malabar-biomethane-injection-plant-a-new-approach-for-circular-resource-management-and-energy-generation-in-australia/ – The Malabar Biomethane Injection Plant, situated within the Malabar Headland National Park, represents a groundbreaking step in Australia’s energy landscape. This collaborative demonstration project, led by Jemena and Zinfra together with Sydney Water, and co-funded by ARENA, addresses the dual challenges of waste management and sustainable energy production. The plant transforms biogas produced at the Malabar Water Resource Recovery Facility into biomethane suitable for household and commercial use—a first in Australia to inject biomethane into the gas distribution network.
- https://www.gorenewablegas.com.au/zh-cn/renewable-gas-projects/malabar-biomethane-plant – The Malabar Biomethane Injection Plant is Australia’s first biomethane-to-gas-network project, demonstrating how homes and businesses can use renewable gas sourced from biowaste and blended with natural gas for cooking, heating, and hot water. Jemena and Sydney Water are working together to produce biomethane at the Malabar Wastewater Treatment Plant in south-east Sydney. The high-quality biomethane gas meets the Australian Standard (AS4564:2020) for injection into Jemena’s NSW natural gas distribution network—the largest in Australia with over 1.5 million customers.
- https://arena.gov.au/blog/from-poo-to-you-biomethane-plant-opens/ – A pioneering renewable biomethane facility in the eastern suburbs of Sydney is now operational. Sydney Water’s Malabar Wastewater Treatment Plant processes organic material in wastewater to produce biogas. In the past, the treatment plant has used that biogas to generate electricity and heat or has flared it off. In November 2020, ARENA agreed to provide $5.9 million towards the Malabar Biomethane facility to upgrade the biogas to high purity biomethane, contributing to Australia’s renewable energy initiatives.
