Project description

H2Perth is a proposed commercial scale, hydrogen and ammonia production facility, to be located primarily within the Rockingham Industrial Zone, approximately 40 kilometres south of Perth.

H2Perth is anticipated to be a phased development. Phase 1 of the project is targeting up to 2,700 tonnes per day of ammonia produced through gas reforming (with CCS) and electrolysis. It is targeting supply to local industry and international users.

For the electrolysis component of H2Perth, H2Perth proposes to use a target of 80% renewable electricity from start-up for Phase 1, stepping up to 100% renewable electricity for the entire facility by 2040. The electricity is proposed to be sourced from the South-West Interconnected System and the renewable electricity targets are proposed to be met by using Renewable Energy Certificates from eligible renewable sources under the Renewable Energy (electricity) Act 2000.

Subsequent phases have the potential to expand to 8,900 tonnes per day of ammonia by increasing the electrolysis component.

In April 2023, Woodside and Keppel Data Centres Holding Pte Ltd (Keppel Data Centres) signed a non-binding Heads of Agreement to evaluate the potential supply of liquid hydrogen to Singapore from Woodside’s portfolio of planned production facilities, including the proposed H2Perth facility.

Woodside submitted primary environmental approval application documents to both the Commonwealth and Western Australian regulators in May 2023.

Woodside is operator and holds a 100% participating interest.

Note: The proposed opportunity is subject to commercial arrangements, commercial feasibility, regulatory, Joint Venture approvals (where applicable), and third-party activities (which may or may not proceed). Individual investment decisions are subject to Woodside’s investment targets. Not guidance.

Woodside is also progressing a separate, stand-alone hydrogen opportunity called the Hydrogen Refueller @H2Perth. Hydrogen Refueller @H2Perth would be a self-contained hydrogen production, storage and refuelling station adjacent to the main H2Perth opportunity.
