Renewable Hydrogen to be Injected into Sydney Gas Grid as a Trial

On October 22, 2018, the Australian Renewable Energy Agency (ARENA) announced its support for a two-year trial that will inject renewable hydrogen into the Sydney gas distribution network (operated by Jemena). 

ARENA is providing AUD $7.5 million in funding to Jemena towards the AUD $15-million project, called Project H2GO - to build a demonstration-scale "power-to-gas" 500-kW electrolyzer, in western Sydney. Powered by energy from the sun and wind, the electrolyzer will inject renewable ‘green’ hydrogen into Sydney’s natural gas grid. Hydrogen created will be entirely free of emissions, releasing only water vapor at the point of use.

"As Australia transitions to renewable energy, hydrogen could play an important role as energy storage and also has the effect of decarbonizing the gas network with ‘green’ gas," said ARENA chief executive Darren Miller.

Jemena is currently serving a network of 1.3 million gas customers in New South Wales. According to ARENA and Jemena, Hydrogen can be safely added to the natural gas mains at concentrations of up to 10 percent without affecting pipelines, appliances or regulations.

Most of the hydrogen will be injected in the local gas network for domestic use, some will be used for electricity generation back into the grid and the remainder will be stored for use in an onsite hydrogen refueling station.

The managing director of Jemena, Frank Turdor said power to gas technology could provide a crucial key to making renewable energy dispatchable.

"In the future Australians will need to decide what to do with excess renewable energy on very windy or very sunny days," he said.

"Jemena’s Project H2GO 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."


Earlier last month, AREAN offered a collective fund of AUD $22.1 million to research teams from nine Australian universities and organizations including the ANU, Macquarie and Monash Universities, QUT, RMIT, The University of Melbourne, UNSW, the University of WA, and the CSIRO.
