Frontier Energy has agreed on a preferred pathway to deliver water to the Bristol Springs Renewable Energy Project in WA’s southwest – through the existing Stirling Trunk Main pipeline.

Water is an essential element for green hydrogen production with around nine litres of water required for every one kilogram of hydrogen produced.

Without access to suitable water, a desalination facility would be required, which would add significant capital, additional environmental studies, and regulatory approvals.

After consulting with the Water Corporation, Frontier Energy (ASX:FHE) says it had four options to source water from existing networks and solutions.

The clear standout, however, was accessing scheme water via the Stirling Trunk Main Pipeline given the minimal cost, simplicity, and timing.


Capacity sufficient for 150MW electrolyser

While the indicative usage for stage one is 750kL per day, the pipeline connection proposed by the Water Corporation will have a capacity for 1,250kL per day – sufficient for an electrolyser of 150MW.

This is four times larger than the facility proposed in stage-one (36.6MW facility), however aligns with FHE’s mid-term expansion strategy.

The connection will be off the Stirling Trunk Main which conveys water from the Southern Dams and the Southern Seawater Desalination Plant to the Integrated Water Supply System (IWSS) – currently delivering 303 billion litres of water each year throughout Western Australia.

FHE says the indicative cost for water usage is in line with the assumption of $2.5/Kl in the Pre-Feasibility Study and anticipates finalising the agreement with Water Corporation later this year.
