Welcome to Jemena's Western Sydney Green Gas Project

Sydney homes and businesses could use ‘green gas’ for cooking, heating and hot water thanks to Australia’s largest renewable gas demonstration

Innovation doesn’t always mean something new has been invented. We can also deliver benefits to customers and improve network efficiencies by exploring new ways to utilise current assets and existing technologies. Jemena’s Western Sydney Green Gas demonstration is a case in point. The renewable gas project will convert solar and wind power into hydrogen gas, via electrolysis, which will then be stored for use across the Jemena Gas Network (JGN) in New South Wales, the biggest gas distribution network in Australia. If the demonstration to power 250 homes and a hydrogen vehicle refuelling station is successful, we’ll look to expand it across the NSW network.

What they said

“In the future Australians will need to decide what to do with excess renewable energy on very windy or very sunny days. Jemena’s Western Sydney Green Gas Project will demonstrate how existing gas pipeline technology can store excess renewable energy for weeks and months, making it more efficient than batteries which can only store excess renewable energy for minutes or hours.”
Frank Tudor, Managing Director, Jemena.

Project Profile

  • The $15 million demonstration is co-funded by Jemena and the Australia Renewable Energy Agency (ARENA).
  • A 500kW electrolyser will be able to generate enough hydrogen to power approximately 250 homes.
  • The JGN supplies more than 1.4 million customers each year.
  • The JGN is 25,000 kilometres in length and is capable of storing as much energy as 8 million Powerwall bateries.
  • Hydrogen is carbon neutral and the Western Sydney Green Gas Project will ensure homes and businesses in New South Wales can be powered by clean, green renewable energy.
  • The project will contribute to the NSW Government’s Stage 1, Net Zero Plan, to cut emissions by 35 per cent by 2030 compared to 2005 levels.
  • The Project can support refuelling for public and private hydrogen transport. Jemena has signed an MOU with Coregas and Hyundai to support Hyundai's hydrogen vehicle fleet.
