Biogas Power Station

Works have begun to fabricate a biomethane upgrader as part of Australia’s first biomethane-to-gas network project, Jemena’s $16 million Malabar Biomethane project.

The project is one of Jemena’s suite of renewable gas initiatives. It is being developed in partnership with Sydney Water and co-funded by the Australian Renewable Energy Agency.

Biomethane upgraders remove water, carbon dioxide, other gases and contaminants from wastewater to produce renewable biomethane which can then be injected into the gas network. 

It will be the first of its kind to be fabricated in Australia.

Brisbane company Eneraque is fabricating the upgrader package for Australia’s first biomethane-to-gas network project. 

Jemena’s General Manager of Renewable Gas, Gabrielle Sycamore, said that Jemena was pleased that work on the upgrader was being undertaken in Australia, leveraging local manufacturing expertise and capabilities.

“Fabricating the upgrader package in Australia is a great step towards helping to build a new design and manufacturing industry which will support our renewable energy transition,” Ms Sycamore said.

“We’re excited about the potential for bioenergy and biofuels to help decarbonise sectors of our economy, like manufacturing, which rely on gas as a feedstock, as well as provide renewable gas for customers to use at home.

“Biomethane production is a great example of creating a circular economy – it keeps products and materials in use, reducing the production of new waste and pollution, and regenerating natural systems.

“Projections indicate that by the start of the next decade, with the right policy support, the bioenergy sector could create about 26,200 jobs.”

According to the Australian Government’s Bioenergy Roadmap, released in November 2021, in addition to new jobs, the bioenergy sector could contribute to around $10 billion in extra GDP per annum, reduce emissions by about 9 per cent, divert an extra 6 per cent of waste from landfill, and enhance fuel security.

As part of its suite of renewable gas projects, Jemena is partnering with Sydney Water on this $16 million biomethane project, to be located at the Malabar Wastewater Treatment Plant, in South Sydney. The project is co-funded by the Australian Renewable Energy Agency (ARENA).

The Malabar Biomethane project is expected to remove 5,000t of carbon emissions – the equivalent of taking around 4,500 cars off the road – and potentially 11,000t if scaled up to its full potential.

This would make it a significant contributor to the New South Wales Government’s Stage 1, Net Zero Plan, to cut emissions by 35 per cent by 2030 compared to 2005 levels.

The facility is expected to produce the first biomethane for injection into the Sydney gas network later in 2022. 

It will be the first participant in GreenPower’s renewable gas certification pilot, which will help energy customers directly support Australian renewable gas projects.
