Hydrogen Delivery System – Tallawarra A Power Station
Client: Energy Australia (in partnership with Coregas)
Location: Illawarra, NSW
Project Scope: Hydrogen delivery pipeline and bulk storage distribution facility
Completion: September 2022
Sector: Energy Infrastructure / Power Generation
As part of Energy Australia’s push toward cleaner energy generation, Tallawarra A Power Station required the installation of a dedicated hydrogen fuel delivery system to support turbine cooling operations.
Umech was engaged by Coregas to deliver a design-and-construct solution for bulk hydrogen delivery, including high-spec pipeline installation, hazardous area compliance, and the construction of a custom hydrogen distribution and control facility.
Umech’s Role
Umech provided end-to-end engineering, installation, and commissioning of the hydrogen system:
Design and installation of 300+ metres of 1.5" stainless steel hydrogen piping, surface-mounted and routed across the turbine facility
Hazardous Area Classification and compliance planning
Construction of a bulk storage and distribution shed to house 10x hydrogen manifold packs
Custom nitrogen purging system for pipeline and manifold safety
Fabrication and installation of a compliant hydrogen vent stack for system depressurization
Design and build of concrete slab, structural steelwork, and housing infrastructure
Integration of a PLC-controlled delivery and monitoring system
Facilitation of HAZOP workshops with engineers from Energy Australia and Coregas to verify design safety and operational performance
Technical Highlights
Hazardous Area Compliance: All components rated and installed to ensure safe operation under AS/NZS 60079
Nitrogen purge system with integrated bypass for controlled pressurisation
Structural and civil works to support large-scale manifold deliveries and storage
Ventilation and exhaust design to ensure hydrogen safety during transfer and depressurisation
System fully hazoped and verified in collaboration with power station and gas supplier engineering teams
Outcome
Umech successfully delivered a critical hydrogen infrastructure upgrade for one of Australia’s landmark gas-to-hydrogen energy transition projects. The system is now operational and safely supports hydrogen cooling functions at Tallawarra A.
Our role bridged civil, mechanical, electrical, and control engineering — with hydrogen safety at the core of every detail.
