Navigating the Transition to Green

Ammonia has long been a critical component in global agriculture and industry, primarily through its role in fertilisers. However, it is now being increasingly recognised as a potential clean energy carrier, especially in decarbonising industries like shipping and heavy transport. Yet, despite ammonia’s growing potential, the environmental impacts of its traditional production methods, particularly grey ammonia, present a significant challenge. Current ammonia production is heavily reliant on steam methane reforming (SMR), an energy-intensive process that emits approximately 36 million tons of CO2 annually in Europe alone. As the world turns its focus to decarbonisation, transitioning from grey to green ammonia is a vital component in mitigating climate change and achieving global sustainability targets.

Economic Considerations: The Cost Differential and Subsidies

One of the most critical challenges in the shift toward green ammonia is its current cost, which is about 2 to 3 times higher than grey ammonia. While green ammonia production via electrolysis offers significant emissions reductions, it is still hindered by the high costs of electrolyses and the capital investment required for renewable energy infrastructure. However, as we have seen in other industries, such as solar and wind power, costs can drop dramatically with increased adoption and technological improvements. For example, the cost of solar energy fell by 89% over the last decade due to scaling and technological advances.

Government subsidies and carbon pricing will play a crucial role in lowering the cost of green ammonia. Just as electric vehicles and renewable energy adoption were boosted by financial incentives, a similar pathway is emerging for green ammonia. The European Union’s hydrogen strategy and policies, such as the European Hydrogen Bank and REPowerEU, are examples of how subsidies and regulatory frameworks can help drive the transition. These early investments are crucial not only to scale production but also to ensure a competitive future for green ammonia.

Technological Innovation and Historical Precedents

The technologies that make green ammonia possible, such as water electrolysis and carbon capture, are already in place but need significant investment to scale. While the concept of blue ammonia, which integrates carbon capture and storage (CCS) with traditional hydrogen production, is a valuable intermediate step, the ultimate goal is to transition to fully green ammonia powered by renewables. The complexity of this transition mirrors the global shift to renewable energy in previous decades. Early adopters of solar and wind technology benefited from tax incentives, IP advantages, and first-mover positioning, despite facing high upfront costs and technological challenges.

The parallels are clear: just as renewables reached cost parity with fossil fuels, green ammonia is likely to follow a similar trajectory as production costs decline. Those who invest early—whether through government support or private funding—will position themselves at the forefront of this emerging market.

Early Adopters and Investment Opportunities

For early adopters of green ammonia technologies, the potential benefits are substantial. Companies investing in green ammonia production today will secure long-term contracts, establish intellectual property (IP) rights, and capture market share in a sector poised for significant growth. Regions like Australia, Morocco, and the Middle East are leading the charge, leveraging their abundant renewable energy resources to build large-scale green ammonia facilities. Their early investments are not only aimed at reducing emissions but also at securing future competitive advantages in a low-carbon global economy.

As the transition gains momentum, these first movers will benefit from securing government contracts, particularly in nations with aggressive net-zero targets. Early investments in green ammonia align with national and international climate policies, further ensuring that these early players will capture a disproportionate share of the market.

Challenges in the Transition to Green Ammonia

Despite the clear benefits of green ammonia, significant hurdles remain. High capital costs, regulatory uncertainties, and the need for substantial infrastructure investment are major challenges. Transitioning to green ammonia requires not only new electrolysers and renewable energy systems but also storage, transportation, and distribution infrastructure—elements that are not yet fully developed on a global scale.

Furthermore, as highlighted by the challenges faced by past hydrogen projects, such as the Hannover hydrogen project, it is clear that transitioning too rapidly without sufficient market readiness and infrastructure planning can lead to failure. Comprehensive planning, supported by robust policy frameworks, will be necessary to avoid repeating these mistakes and ensure a smooth transition for green ammonia production.

Market Dynamics and Future Outlook

Currently, the ammonia market is experiencing significant shifts, with supply chain disruptions, price fluctuations, and maintenance issues at key production facilities adding volatility. As we’ve seen, these supply disruptions have caused price spikes, where supply tightness and rising demand have increased market pressures. This trend, however, is only a glimpse of what’s to come.

In the future, ammonia demand is expected to rise even further, driven not only by its traditional use in fertilisers but also as a clean fuel alternative and a hydrogen carrier. The global shipping industry, in particular, is exploring ammonia as a zero-emission fuel, which could dramatically increase demand and further incentivise the transition to green ammonia. As renewable energy prices continue to fall and production technology improves, green ammonia will likely follow the same path as solar and wind energy, achieving cost parity with grey ammonia within the next decade.

Global Examples of Green Transitions

The global energy market offers numerous examples of successful green transitions. Countries like Germany, with its Energiewende, or China’s push for solar and wind energy, have shown how early government intervention, coupled with private sector investment, can drive large-scale adoption of renewable technologies. In both cases, early investments were supported by subsidies, regulatory frameworks, and international collaboration, all of which were essential in achieving widespread adoption.

For green ammonia, a similar approach will be required. Governments will need to continue providing subsidies, while international bodies like the UN and the International Energy Agency (IEA) will play a role in coordinating cross-border efforts to create a global green ammonia market. Public-private partnerships will be essential to overcome the hurdles of high capital costs and infrastructure needs.

The Path Forward

The transition from grey to green ammonia is a long-term process, one that will take 15-30 years of steady investment and development. But the potential benefits are immense. Green ammonia offers a pathway to decarbonise critical sectors, from agriculture to heavy industry and shipping, while positioning early adopters for significant economic and competitive advantages.

As we move forward, it’s crucial to strike a balance between profitability and sustainability. The Māori concept of Kaitiakitanga—stewardship of the land—emphasises that sustainability cannot come at the expense of economic viability. Instead, we must focus on creating a balanced approach that supports both long-term environmental goals and short-term economic needs. This principle is not only applicable to New Zealand but is a valuable guiding framework for the global transition to green ammonia.

In conclusion, green ammonia is poised to transform the ammonia industry and beyond. While the road ahead is complex, with careful planning, strategic investment, and international collaboration, the transition will unlock both environmental and economic benefits for industries worldwide.
