CQ-H2 Connection Project

Overview

Powerlink has been engaged by Stanwell to connect the Central Queensland Hydrogen Project (CQ-H2) at Aldoga, near Gladstone, to the electricity grid.

This transmission connection project includes construction of a 4.5km 275kV transmission line from Powerlink’s existing Larcom Creek Substation to a new substation being built at the CQ-H2 Hydrogen Production Facility. Transmission line corridor selection work, easement acquisition and associated approvals will be completed by Powerlink.

Central Queensland Hydrogen Project (CQ-H2)

The CQ-H2 Project is managed by a global collaboration of domestic and international partners. 

The project involves development of a Hydrogen Production Facility, Hydrogen Gas Pipeline, Hydrogen Liquefaction Facility, Ammonia Synthesis Plant and ship loading facility at the Gladstone Port.  

Powerlink will be connecting the Hydrogen Production Facility in Aldoga to the electricity grid. 

This facility will produce hydrogen through electrolysis, using electricity generated from renewable sources, such as wind and/or solar power, to split water into hydrogen and oxygen.  For further information about the CQ-H2 project please refer to their website.

Status

As part of the regulatory approval process for this grid connection project, survey works will commence in early 2025.

Construction of the transmission line will commence by mid 2026, with works expected to be completed by mid 2028.
