Australian solar park could generate hydrogen for less than $2/kg

A new study shows that hydrogen could be produced for as little as AUD 2.85 ($1.98) per kilogram, supporting Frontier Energy’s plans to make green hydrogen from a 500 MW solar project it is developing in Western Australia.

Frontier Energy said that results from a pre-feasibility study (PFS) into its proposed Bristol Springs Solar project in Western Australia show that it has the potential to be an early mover, low-cost green hydrogen producer.

The PFS, conducted by Perth-based Xodus Group, is based on the development of a large-scale green hydrogen production facility at Bristol Springs, with power sourced from the company’s planned first stage 114 MWdc solar farm. The solar would power a 36.6 MW alkaline electrolyzer, producing an estimated 4.4 million kilograms of green hydrogen per year.

Including the estimated capital outlay, the study forecasts a total unit cost of AUD 2.83 per kilogram of hydrogen produced which Frontier said “places the project as one of Australia’s lowest cost green hydrogen producers.” The projected cost of production also places the project within reach of the economic goal of producing green hydrogen for AUD 2 per kg, which would be cost-competitive with gas produced from fossil fuels.

Frontier said the projected unit cost of $2.83 per kg is also far lower than the Australian Renewable Energy Agency’s (ARENA) current green hydrogen production cost forecast of between $6 to $9 per kg based on current electrolyser and renewable energy costs.

Frontier executive chair Grant Davey said the low cost is due in part to the project’s location near Waroona, about 120 kilometres south of Perth. To be built on a 195-hectare site next to the Worsley alumina refinery, the project is able to access existing infrastructure, including the Landwehr Terminal power line, allowing for excess solar energy to be sold via WA’s main energy grid. The company said there are also several established water sources in the area, meaning there is no requirement for capital-intensive infrastructure like desalination.

“Green hydrogen is a unique opportunity to store, move and distribute renewable energy and is set to play a huge role in helping humanity in decarbonising the energy we need,” Davey said.

“The Frontier Energy green hydrogen project is strategically located with suitable land, abundant water, South West Interconnected System (SWIS) access, gas pipeline access and transport infrastructure so as to be an Australian leader in ensuring that green hydrogen production and distribution becomes a near-term reality.”
