Stanwell is investigating the feasibility of a large (10 MW or bigger) hydrogen electrolysis demonstration plant at Stanwell Power Station, near Rockhampton in Queensland.
The Stanwell Hydrogen Electrolysis Deployment Feasibility Study acknowledges that two key challenges of producing cost-competitive green hydrogen by electrolysis are high capital costs and the low capacity factor of variable renewable energy.
Stanwell’s feasibility study will assess the commercial, technical and strategic viability of hydrogen produced via electrolysis using renewable power resources.
The Stanwell Hydrogen Electrolysis Deployment Feasibility Study will identify and assess reference projects and develop a knowledge base to support long-term commercial hydrogen strategies and export opportunities.
The study will consider pathways that include:
- on-site hydrogen gas production (for gas network injection, renewable methane, mobility and/or export)
- on-site ammonia production
- power generation.
Technical analysis will review foundational technology models and site integration outcomes, including hydrogen production technologies and site electrical connection.
A techno-economic assessment will determine the hydrogen production technology (alkaline or PEM) that best supports commercialisation of a Central Queensland hydrogen industry.
If feasible, Stanwell’s hydrogen project would encourage the growth of a green hydrogen and ammonia export industry in Central Queensland, help ease electricity network constraints and support the growth of renewable energy in the region.
It will do this by deploying electrolysis at large scale, harnessing economies of scale in equipment production and deployment, and maximising utilisation of the electrolyser through high capacity factor electricity from Stanwell Power Station.
