Renewable hydrogen hopeful Infinite Green Energy has laid out its plans to build up to 235MW of wind and solar capacity to produce up to 43 tonnes of green hydrogen at its Arrowsmith project in Western Australia.
Infinite Green, which used to be known as Infinite Blue Energy before it realised the importance of colour coding in the nascent hydrogen industry, has filed its planning document for the project with the WA Environmental Protection Authority.
The 1930 hectare property, south of Dongarra, has been used for sheep, cattle and goat grazing, but will now support up to 85MW of utility scale solar PV, up to 150MW of wind energy, and 20MW of battery storage (no storage duration has been revealed at this stage).
This, Infinite Green says, will produce between 23 and 42 tonnes of green hydrogen a day, which will be transported offsite in the form of a cryogenic liquid loaded on to hydrogen fuel trucks.
Infinite Green hopes to begin construction in 2023, and start production in 2025. It is one of a number of green hydrogen projects proposed by the state, and could be the biggest – for a while – if it meets its timeline, although it will be quickly trumped by much bigger projects over time.
It appears to have already chosen its wind turbines –Â up to 25 6MW Vestas V-162 turbines, and plans to use the battery storage to smooth out the output of the wind and solar facilities.
It says the site has been chosen due to its “abundance of wind and solar power” and an “abundant quantity” of quality fresh water. It will use 2,340 kL of water a day, drawn from local aquifers.
It says the proposed layout has been arranged to avoid wetlands, karst formations and Carnaby’s Black Cockatoo habitat on the property.
