Woodside to build $1bn Perth hydrogen plant

Energy and LNG export group Woodside has announced plans to spend an initial $1 billion constructing a hydrogen and ammonia production plant at Kwinana south of Perth with output destined for export.

However – bucking the recent trend – the plant will not be totally ‘green’.

Woodside said that its H2Perth project (pictured) would produce up to 1,500 tonnes a day of ‘low cost, low carbon’ hydrogen utilising both electrolysis and natural gas as a feedstock.

To be built on a 130 hectare site, the electrolysis component of H2Perth would initially have a capacity of 250 megawatts, with potential to scale up to three gigawatts.

The power generation capacity of Western Australia’s entire South West Interconnected System is 5.8GW, suggesting massive investment in power generation – likely from renewable sources – will be needed.

The initial capacity of steam methane reformer would consume 40 terajoules per day of natural gas.

Woodside claims the plant would be ‘net-zero emissions’, with 100 per cent of emissions abated or offset.

CEO Meg O’Neill said: “We intend to use our skills and financial strength to add new energy products and lower-carbon technologies and services to our portfolio which can be scaled to meet customer demand.

“…H2Perth will also facilitate substantial growth of renewables in Western Australia.”
