What Is Holding Back Australia’s Green Hydrogen and Green Ammonia Market?

Australia has many of the ingredients needed to become a global leader in green hydrogen and green ammonia. It has abundant renewable resources, strong policy support, and growing international interest from key trading partners.

And yet, despite this momentum, relatively few projects have reached final investment decision or large-scale commercial operation.

The reason is not a lack of ambition or technology. It is that the market is still trying to solve a more fundamental problem: how to turn green hydrogen and green ammonia into bankable, scalable businesses.

From Technical Feasibility to Commercial Reality

Over the past decade, the conversation around hydrogen has shifted significantly.

Early discussions focused on whether green hydrogen could be produced at scale. Today, that question is largely settled. Electrolysis technology is proven, renewable energy costs continue to decline, and pilot projects are operating across multiple regions.

The challenge has now moved to a different level. It is no longer about whether hydrogen can be produced, but whether it can be produced at a cost, and under contractual conditions, that make large-scale projects financeable.

This distinction is critical. In energy markets, technical feasibility is only the first step; commercial viability determines whether projects are built.

The Cost Gap Remains Significant

One of the most widely cited barriers is cost.

Green hydrogen remains more expensive than hydrogen produced from fossil fuels in most markets, particularly when natural gas prices are low. The same applies to green ammonia compared to conventional ammonia.

This cost gap creates a structural problem. While many industrial buyers express interest in low-carbon products, relatively few are willing to commit to long-term contracts at a significant price premium.

As a result, projects often struggle to secure the kind of long-term off-take agreements that are typically required to unlock financing.

In this sense, the issue is not simply production cost—it is the gap between what producers need to charge and what buyers are willing to pay.

Demand Is Uncertain and Still Emerging

Closely linked to cost is the question of demand.

In theory, future demand for green hydrogen and green ammonia is substantial, particularly in sectors such as heavy industry, chemicals, and shipping. In practice, however, much of this demand remains policy-driven rather than market-driven.

Many potential buyers are still in an exploratory phase, assessing technology options, regulatory requirements, and cost trajectories. This creates a mismatch between project timelines and demand certainty.

For developers, this uncertainty makes it difficult to move forward with large-scale investments. Without credible, long-term demand signals, even well-designed projects can remain stuck at the feasibility stage.

Infrastructure and System Integration Challenges

Another constraint lies in infrastructure.

Green hydrogen and ammonia projects are not standalone facilities. They depend on a broader system that includes renewable generation, grid connections, water supply, storage, transport, and export infrastructure.

In Australia, this often means projects are located in remote regions with strong renewable resources but limited existing infrastructure. Building the necessary supporting systems can significantly increase both cost and complexity.

This is why many projects are evolving into integrated developments, combining renewable energy, hydrogen production, and export logistics in a single coordinated system.

While this approach is strategically sound, it also raises execution risk and extends development timelines.

Financing and Risk Allocation

Ultimately, these challenges converge in the question of financing.

Large-scale hydrogen and ammonia projects require substantial upfront capital investment. To secure that investment, developers need to demonstrate predictable revenue streams, manageable risks, and credible long-term demand. At present, many of these conditions are only partially met.

This is why government support mechanisms—such as production incentives, grants, and contracts-for-difference-style schemes—are becoming increasingly important. They help bridge the gap between current market conditions and the level of certainty required for private investment.

In Australia, recent initiatives such as hydrogen production incentives and targeted funding programs reflect a growing recognition that policy support is essential to move projects from concept to execution.

What This Means for the Market

Taken together, these constraints point to a more nuanced conclusion.

Australia’s green hydrogen and green ammonia market is not being held back by a lack of resources or strategic intent. It is being shaped by the practical realities of cost, demand uncertainty, infrastructure, and financing—and by the need to identify business models that work under real-world conditions.

While export-oriented projects continue to attract attention, the market is also beginning to explore a different pathway: localised production and use.

In this model, green ammonia is not primarily produced for long-distance trade, but for on-site or regional consumption, particularly in industrial operations, mining, and remote energy systems. By aligning production with immediate demand, this approach can reduce the need for large-scale transport and storage infrastructure, improving overall project economics.

This “produce-and-use” model also opens the door to smaller-scale developments, where green ammonia can be integrated into existing industrial processes or used as a flexible energy carrier. In some cases, these smaller, modular projects may prove more viable in the near term than large export-focused developments, especially where infrastructure constraints are significant.

From a market perspective, this suggests that the future of green ammonia in Australia may not follow a single pathway.

Instead, it is likely to develop along two parallel tracks: one focused on export-oriented, large-scale production, and another centred on localised, demand-driven applications.

Hydrogen remains central as the underlying production pathway. But ammonia’s role is becoming more clearly defined—not only as a potential export commodity, but also as a practical tool for decarbonising industrial activity closer to where energy is produced.

In that sense, the key question for Australia is not simply whether it can export green hydrogen or green ammonia at scale. It is whether it can deploy these technologies in ways that are commercially viable across different contexts—globally and locally.
