World’s largest green ammonia plant in South Australia gets boost

The initial stage of the AUD240 million (USD173 million) H2U Eyre Peninsula Gateway Hydrogen Project, the world’s largest green ammonia plant, has received a boost from the South Australian government.

The South Australian Government announced that it will allocate AUD37 million (USD26 million) to upgrade the nearby Port Bonython jetty as part of its plan to become an exporter of green energy to world markets.

The announcement comes just a week after the state launched the SA Hydrogen Action Plan, which identified Port Bonython as a key hub.

The H2U plant will use 100% wind and solar power generated in the region to power the electrolyser to split water into hydrogen and oxygen gas.

A further process using nitrogen is used to make green ammonia.

The H2U Eyre Peninsula Gateway Hydrogen Project  will include the installation of a 75MW electrolyser near the regional city of Whyalla, capable of producing enough hydrogen to create 40,000 tonnes of ammonia each year.

The plant will also feature two 16 MW open cycle gas turbines operating 100% on hydrogen at the site to provide electricity generation to the grid during periods of low wind or solar output.

H2U Chief Executive Officer Dr. Attilio Pigneri said the project would help drive the development of the emerging green hydrogen and green ammonia markets.

“(It) offers the opportunity to export South Australia’s abundant solar and wind resources to support deep decarbonisation in the global energy, industrial and shipping sectors,” he said.

“In the energy sector, Japan is leading the way with their plan to introduce green ammonia as a substitute fuel, to help meet its decarbonisation targets.”

The project is targeting completion by late 2022.

Considered one of the most prospective chemical carriers of hydrogen, green ammonia – a chemical compound of nitrogen and renewable hydrogen – is also a potential fuel for large-scale power stations, making it an attractive export opportunity.

H2U and the South Australian Government last year joined Japan’s Green Ammonia Consortium. The consortium comprises more than 70 companies and institutions including the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Trade and Investment Commission.

South Australian Premier Steven Marshall said the exportation of green hydrogen would strengthen energy ties with international trading partners.

“The AUD240 million (USD173 million) demonstrator phase of the project is of global significance, but it is just the precursor to a much larger production and export facility,” Marshall said.

Other key hydrogen projects utilising state government funding underway in South Australia include:

  • An AUD8.7 million (USD6 million) facility at the University of South Australia’s Mawson Lakes campus incorporating a solar installation, flow batteries, a hydrogen fuel storage cell stack and thermal energy storage to demonstrate the value of hydrogen storage paired with other new storage technologies.
  • Neoen Australia is investigating the introduction of a 50 MW hydrogen super hub to produce about 25,000 kg of hydrogen a day at its proposed Crystal Brook Energy Park in the Mid North of South Australia.

South Australia leads Australia in the uptake of wind energy and roof-top solar with renewable sources accounting for more than 70% of the electricity generated in the state.

The state is also home to the world’s largest lithium-ion battery (100 MW/129 MWh), which was established in late 2017 at Neoen’s Hornsdale Wind Farm in the state’s Mid-North.
