Project description

The Arrowsmith Hydrogen Project, being developed by Infinite Blue Energy, will produce up to 25 tonnes (25,000 kilograms) per day of green hydrogen. The plant, located in Arrowsmith, Western Australia, north of Perth, will be domiciled in an area with exemplary renewable energy resources. Green hydrogen will be produced utilising a combination of renewable energy from solar (up to 90 MW) and wind (up to 144 MW) and will displace 118,000 tonnes of CO2 emissions annually.

The project is expected to come online in late 2025 and will serve the domestic Western Australian energy and transport markets.

The Front End Engineering and Design (FEED) study for Stage 1 was undertaken by Petrofac and completed in early 2021. The Arrowsmith facility includes a 60MW alkaline electrolyser facility and options for a 30 tonne per day liquefaction system.

The proponent has executed a 20-year offtake agreement with 2 x 5-year extensions for 100 per cent of the Arrowsmith Hydrogen production. The hydrogen will be delivered in liquid form to Top Group’s existing roadhouse infrastructure (which supports vehicles travelling from Perth to regional Western Australia, including the Pilbara area) and new locations being developed. The off take quantity would ramp up to full production over an anticipated 12 month period.

The company plans to make its submission to the EPA for environmental impact assessment in the first half of 2022.

The proponent is in the final stages of discussions to secure a strategic partner for the Arrowsmith development.
