Construction of Jemena’s Western Sydney Green Gas Project underway

Australian energy infrastructure company Jemena has started construction of its pioneering $15m project that will see 250 homes in New South Wales powered by green hydrogen later this year.

Jemena’s Western Sydney Green Gas Project is building a demonstration scale power-to-gas electrolyser powered by solar and wind energy.

The 500kW electrolyser will inject green hydrogen gas into Sydney’s existing natural gas grid, the Jemena Gas Network – the biggest gas distribution network in Australia.

If scaled, power-to-gas hydrogen technology could help green the gas network, supplementing existing natural gas with carbon free hydrogen generated by wind and solar power.

A portion of hydrogen produced as part of the trial will be diverted to a gas engine generator to generate electricity to be exported back into the grid, with hydrogen off take made accessible for use in an onsite hydrogen fuelling station for fuel cell vehicles.

“In the future Australians will need to decide what to do with excess renewable energy on very windy or very sunny days,” said Frank Tudor, Managing Director of Jemena.

“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.”

Jointly launched in 2018 with the federal government’s Australian Renewable Energy Agency (ARENA), the project is Australia’s most comprehensive hydrogen demonstration and will test three areas: the generation of hydrogen gas from solar and wind power; the storage of hydrogen in existing assets; and provide off-take for the vehicle industry.

In July 2020, H2 View asked Jemena’s Managing Director Frank Tudor some key questions on the project. If you missed that interview, read it again here.
