UMOE Advanced Composites has manufactured five multi-element gas containers at its Jiaxing facility in China and is shipping them to the Hiringa Sundown hydrogen and ammonia project in Australia. The dispatch marks its first international commercial shipment of the modules from the Chinese plant. UMOE identified the same order when production started in March; the new development is completion of manufacture and the move into export delivery.
Two 20-foot and three 40-foot multi-element gas containers, or MEGCs, are being sent to the Good Earth Green Hydrogen and Ammonia project near Moree in New South Wales. The project is developed by Hiringa Sundown, a joint venture between Hiringa Energy and Sundown Pastoral Company. Each container brings multiple composite pressure vessels together in a framed unit intended for compressed-gas storage and transport.
Type IV cylinders use a non-metallic liner to contain the gas, surrounded by a fibre-reinforced composite structure that carries much of the pressure load. UMOE’s design uses glass-fibre reinforcement. Compared with a conventional heavy all-metal vessel, a composite cylinder can reduce the weight of the storage system, although the overall benefit depends on pressure rating, vessel arrangement, protective hardware and the required transport specification.
UMOE rates the 40-foot MEGC design to store up to 720kg of hydrogen. That is the manufacturer’s stated capacity for the product type, with the practical quantity carried governed by the selected filling pressure and operating conditions. The unit also requires a suitable transport frame, valves, protective systems and connections to the destination’s storage and filling equipment.
The hydrogen logistics challenge is governed partly by the low density of the gas. Compression raises the amount carried in a given volume, but high-pressure operation requires vessels with a qualified pressure boundary, valves, protective assemblies and suitable filling procedures. Reducing the module’s unladen weight can create more of a vehicle’s permitted mass allowance for gas or other equipment; it does not remove the need for route planning, inspection and safe operating procedures.
Jiaxing covers around 12,000m² and has potential annual capacity of up to 20,000 composite cylinders. Production of the initial Australian order was previously identified as part of the plant’s ramp-up; shipping the finished containers now takes that work into international commercial delivery. UMOE combines technology developed in Norway with manufacturing and supplier capacity in China, alongside its existing Norwegian operations.
The company reports more than 12,000 of its glass-fibre Type IV cylinders in operation across over 40 countries, reflecting a wider installed base developed over more than two decades. The Jiaxing cylinders are a newer part of that manufacturing record. Existing field experience helps establish how the technology is used, while customers still need to qualify the specific container configuration and operating conditions at each project.
The containers are intended to form part of the hydrogen storage and logistics system for the Good Earth project. The Australian development brings renewable electricity, electrolysis and ammonia production together to provide lower-carbon fuels and fertiliser-related products for regional agriculture and transport. Its planned ammonia output is up to 4,500 tonnes a year, with the production plant still moving through construction and installation.
Hydrogen produced by electrolysis can be used directly in suitable equipment or combined with nitrogen to manufacture ammonia. A site using both pathways requires decisions about the amount of hydrogen retained for immediate processing, the amount held as a buffer and the quantity available for transport. Compressed-gas modules provide one possible means of moving or storing hydrogen, but their operational role depends on the final plant process and distribution arrangements.
The project is located near the Wathagar cotton ginning operation and is being developed by the Hiringa Sundown joint venture. New South Wales approved the scheme earlier in 2026 and is supporting its development through a hydrogen funding initiative. Other equipment for the ammonia production operation has been manufactured and shipped separately, while installation and commissioning are the steps needed before the project can reach its proposed output.
UMOE previously supplied Norway-manufactured Type IV containers for four hydrogen refuelling stations operated by Hiringa in New Zealand. The latest order extends the same commercial relationship to the Australian project, this time using equipment completed in China. The change in manufacturing location adds a separate quality and logistics step to a technology already used by the customer.
The Chinese facility is also intended to serve domestic customers. UMOE says this international shipment advances the certification process for its Type IV high-pressure glass-fibre vessels in China, where domestic approval remains a separate requirement. Approval for domestic Chinese use is progressing independently of the export shipment.
The amount of hydrogen that can be delivered per journey depends on pressure, cylinder capacity and the full weight of the frame, fittings and vehicle. Lighter composite pressure vessels can leave more of a vehicle’s permitted weight available for payload, but transport costs will also reflect filling infrastructure, route length, loading time, return journeys and inspection. UMOE expects its manufacturing arrangement to improve costs and flexibility; it has not attached a quantified saving to this particular shipment.
The five containers have moved from factory production into export shipment for Good Earth, where they are intended to support the hydrogen storage and logistics system. Integration and commissioning at the project will follow as its electrolysis and ammonia facilities progress towards operation.
