Worley has completed a strategic advisory study for the Australian Renewable Energy Agency examining capital costs in renewable-hydrogen development. Announced on 10 September 2026, the work focuses on actions that could influence future project costs. It is a completed advisory assignment, rather than a construction award, an investment decision for a hydrogen plant or a report that a specific production facility has reached a lower operating cost.

The Australia-based team examined 24 independent capital cost-reduction concepts with support from Worley's global hydrogen and project-delivery specialists. The study assessed their combined effects across future development horizons. Worley contrasts this approach with forecasts relying mainly on broad learning-rate assumptions, presenting a more explicit examination of individual cost levers and how they interact.

According to the announcement, the work has supported executive discussions within ARENA and broader planning. The release does not publish a universal cost-reduction percentage or a guaranteed hydrogen selling price. Its capital-cost focus should also remain separate from a claim about the full cost of hydrogen production, which would require a more complete set of operating and financing assumptions.

EPC Feed considers the interaction between cost levers the important project-development issue. Two changes considered separately cannot automatically be added together if they affect the same equipment or depend on the same delivery assumption. A transparent model can help decision-makers ask which combinations remain consistent and which need further engineering evidence. The announcement describes that analytical purpose without providing enough detail to independently reproduce every calculation or validate a numerical outcome.

For developers and suppliers, the completed study is therefore useful as a planning milestone rather than a promise that all future projects will follow one cost trajectory. The next practical question is how its concepts translate into project-specific requirements, procurement decisions and delivery arrangements. Those applications would need their own disclosed evidence. Keeping the advisory result distinct from an operating plant's measured performance preserves the difference between identifying opportunities and demonstrating that a particular facility has realised them.
