Western Sydney Green Gas Project

  • Frequently Asked Questions

    What is the Western Sydney Green Gas Project?

    The Western Sydney Green Gas Project will help bring clean, green and renewable energy to Australian businesses and homes. It will accelerate Australia’s hydrogen vehicle industry. It will use existing infrastructure to make renewable technology cheaper, faster, and more reliable.

    How will you do this?

    Jemena‘s Western Sydney Green Gas Project will convert renewably sourced electricity into hydrogen via electrolysis. A portion of the hydrogen produced will be injected into the gas network, providing enough energy to meet the cooking, heating and hot water requirements of approximately 250 homes. Another portion of the hydrogen will be stored underground supplying a gas engine generator which will provide electricity back to the grid. The project is also considering an onsite Hydrogen Refuelling Station (HRS) for Fuel Cell Electric Buses.

    What is hydrogen?

    Hydrogen is the most common chemical in the universe. It can be produced as a gas or liquid, or made part of other materials, and has many uses such as fuel for transport or heating, a way to store electricity, or a raw material in industrial processes. Hydrogen has zero carbon emissions just like natural gas, hydrogen can be safely transported through existing infrastructure, like pipelines. It can be converted back to electricity or support the existing or international hydrogen market.

    What is the process?

    Through a process called ‘power to gas,’ renewable energy will be converted into hydrogen using an electrolyser – the first of its kind in New South Wales. The electrolyser will use power generated by wind and solar to split water into hydrogen and oxygen. The oxygen is released into the atmosphere; the hydrogen will be stored as renewable energy for weeks and months, making it more efficient than batteries which can only store excess renewable energy for minutes or hours.

    Where will the trial take place?

    The Project will take place at Jemena’s existing Horsley Park site, in western Sydney.

    Why is Jemena undertaking this Project?

    Jemena aims to demonstrate that our gas network is ready to deliver clean, safe and sustainable green gas to customers.

    In doing so, Jemena is supporting the decarbonisation of Australia’s energy market by demonstrating a long term storage solution for renewable energy for when the sun doesn’t shine and the wind doesn’t blow.

    When will the project be built?

    Jemena is currently in the development phase of this project. Jemena expects the Project to be operational in mid 2021.
