Hiringa Energy.

Green-Hydrogen Supply Chain

Hiringa develops production projects that use renewable energy to make hydrogen intended to displace fossil fuels. A viable supply chain requires more than an electrolyser. Renewable electricity, water treatment, compression, storage, dispensing, maintenance, safe operating systems and dependable customer demand all have to work together. Hiringa's positioning across these activities is significant because gaps between production and end use are a common obstacle for early hydrogen markets.

The company also identifies hydrogen as a way to transport renewable energy and support longer-duration storage. Whether that is commercially appropriate depends on the application, energy price, utilisation and available alternatives. For most ordinary electricity use, direct electrification remains more efficient; hydrogen becomes more relevant where energy must be stored, transported or used in equipment that cannot readily depend on a fixed electrical connection.

Heavy-Transport Refuelling

Hiringa says Australasia's first hydrogen-refuelling network is online. Its New Zealand network is designed around important road-freight routes and high-capacity vehicle operation. The stations produce, store and dispense green hydrogen on site. Hiringa promotes typical heavy-vehicle refuelling times of about 15 to 20 minutes, comparatively small payload effects and range broadly comparable with diesel vehicles.

The network supports both fuel cell electric vehicles and hydrogen–diesel dual-fuel vehicles. Fuel cell trucks use hydrogen electrochemically to make electricity for electric traction and have no fossil-fuel exhaust emissions at the vehicle. Dual-fuel conversions retain a diesel engine but introduce hydrogen to displace part of its diesel use. Hiringa publishes indicative emissions reductions of 30–50% for dual-fuel vehicles, while noting their lower capital threshold and ability to continue on diesel where hydrogen is unavailable.

Why the Network Matters

New fuel infrastructure faces a coordination problem: operators hesitate to buy vehicles until fuel is available, while suppliers hesitate to build stations without vehicle demand. A connected network can reduce that barrier by allowing freight operators to plan routes rather than relying on a single demonstration site. It also creates the operating data needed to understand real-world fuel use, reliability, safety, maintenance, driver training and cost.

For New Zealand, the strongest initial case is likely to involve vehicles with high utilisation, predictable routes, central fleet management and a strong need to preserve range or payload. Hydrogen must still compete with battery-electric vehicles, more efficient logistics, renewable diesel and other decarbonisation options. The correct choice depends on route energy, dwell time, depot electricity capacity, vehicle availability, fuel price and the emissions intensity of the hydrogen supplied.

Projects Beyond Road Freight

Hiringa's published project portfolio extends into renewable fertiliser, aviation and industrial decarbonisation. Its website identifies the Kapuni green-hydrogen project, the Riverina Renewable Fertilisers project in Australia, the Harakeke project and participation in a New Zealand aviation consortium. These programmes illustrate how the same underlying capabilities—renewable energy, hydrogen production, storage and long-term customers—can support different end markets.

Large projects remain sensitive to electricity pricing, construction cost, consenting, offtake certainty and the market value of low-emissions products. Their progress should therefore be assessed through current project announcements rather than older ambition alone.

Practical Questions for Customers

A transport operator considering Hiringa's network needs to begin with its actual routes and operating data. Important questions include which stations can serve the fleet, whether vehicles can return to a station without unproductive diversion, how much hydrogen each route requires, how frequently vehicles must refuel and what contingency applies if a station or vehicle is unavailable. Driver training, fuel cards or access arrangements, depot procedures and emergency response also need to be incorporated into normal fleet management.

The commercial comparison should use the complete delivered service rather than fuel price alone. Vehicle capital or lease cost, available incentives, payload, kilometres travelled, maintenance, insurance, fuel consumption, station access and the value customers place on lower-emission freight can all affect the result. A fleet may also introduce hydrogen progressively, beginning with routes that pass existing stations and retaining other technologies for work that the current network cannot yet support.

Safety and Operating Capability

Hydrogen is a regulated flammable gas and requires purpose-designed pressure equipment, ventilation, separation, leak detection, controls and trained operators. Hiringa publishes driver information, station inductions and hydrogen-safety resources for people using its network. These controls are part of the energy service, not optional extras: a successful transition depends on drivers and fleet managers understanding normal refuelling, alarms, prohibited activities and what to do if equipment is damaged.

For industrial supply or a dedicated customer facility, the safety and operating scope becomes broader. Site layout, delivery access, storage inventory, hazardous areas, fire response, maintenance isolation, consenting and interfaces with customer equipment must be established for the particular installation. Early engagement with the supplier, competent engineers, regulators, insurers and emergency services helps prevent a technically promising project from being delayed by requirements that were not allowed for in the initial concept.
