October 22 (Renewables Now) - The Australian Renewable Energy Agency (ARENA) said on Monday it will support a trial that will inject renewable hydrogen into the Sydney gas network.
The government agency will provide AUD 7.5 million (USD 5.3m/EUR 4.6m) towards the AUD-15-million project, called Project H2GO, of New South Wales gas distributor Jemena. The project will see the construction of a 500-kW electrolyser at the company's facility in western Sydney that will convert solar and wind power into hydrogen. 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 refuelling station.
Hydrogen can be added to the natural gas mains at concentrations of up to 10% without affecting pipelines, appliances or regulations, according to the agency.
The two-year trial is the largest of its kind in Australia.
"As Australia transitions to renewable energy, hydrogen could play an important role as energy storage and also has the effect of decarbonising the gas network with ‘green’ gas," said ARENA chief executive Darren Miller.
ARENA is also working to research the opportunity of exporting hydrogen.
