A New Haber-Bosch Moment: Europe Must Reimagine Fertiliser Production
The Role of Ammonia in Modern Agriculture
Ammonia is a critical component of modern agriculture, serving as the primary ingredient in nitrogen fertilizers that sustain global crop yields. It has been instrumental in supporting the world's growing population, with half of the current population relying on synthetic fertilizers for food production. The development of ammonia through the Haber-Bosch process in the early 20th century by German scientists Fritz Haber and Carl Bosch revolutionized food systems and positioned Europe as a leader in scientific and industrial innovation.
However, the same process that once gave Europe an edge now poses significant challenges. The modern food system remains heavily dependent on fossil fuels, particularly natural gas, which is used to produce hydrogen for ammonia synthesis. This reliance makes the agricultural sector vulnerable to fluctuations in gas prices, affecting the competitiveness of European industry and increasing costs across the agricultural value chain.
Economic and Geopolitical Risks
The vulnerability of the European food system became evident following the Russian invasion of Ukraine in 2022. Gas prices surged dramatically, leading to severe disruptions in fertilizer production. At the peak of the crisis, up to 70% of Europe's ammonia production capacity was offline, impacting major companies like BASF. The conflict in the Middle East further highlighted the risks associated with relying on gas imports and fossil fuel-based exports, as approximately one-third of global fertilizer exports pass through the Strait of Hormuz, a critical but vulnerable gateway.
This situation has placed Europe's agriculture under increasing pressure. The continent's declining manufacturing base has led to greater reliance on imported fertilizers from countries such as Algeria, China, Egypt, Russia, and the United States. This creates a paradox: while European policymakers aim to reduce dependence on imported fossil fuels in sectors like transportation, they risk becoming more reliant on imported nutrients produced using the same fossil fuels.
Climate Imperatives and Innovation
There is a pressing need to address the environmental impact of ammonia production. Global ammonia production emits around 450 million tonnes of CO₂ annually, equivalent to twice Spain's annual emissions. Reducing these emissions is crucial for meeting climate targets and ensuring the long-term resilience of food production.
Europe is exploring low-carbon ammonia production methods, such as using hydrogen generated from renewable electricity. However, this approach requires significant new infrastructure for hydrogen production, transport, and storage, which can be costly and time-consuming. Emerging technologies offer a more promising alternative by producing nitrogen-based fertilizers directly from air, water, and electricity. These processes eliminate reliance on fossil gas and could bypass hydrogen altogether, making fertilizer production more reliable, less polluting, and potentially cheaper.
If scaled successfully, these technologies could enable fertilizer production in regions with higher renewable energy potential, including areas outside Europe. Smaller, more flexible plants could complement existing large facilities, enhancing supply chain resilience and creating new industrial opportunities.
Implications for Jobs and Industrial Growth
The shift towards cleaner fertiliser technologies also has implications for employment. Europe's chemical industry supports hundreds of thousands of skilled workers, many located in industrial regions facing challenges due to the energy transition. A new generation of fertiliser technologies could help uplift and modernize this industrial base, preventing the migration of jobs abroad.
Policymakers should support pilot plants and demonstration projects to move emerging technologies from the lab to commercial scale. While early deployment will require investment, it is essential to reduce reliance on volatile gas markets. As renewable electricity expands and new production methods mature, costs are expected to decrease. Europe already possesses strong capabilities in electrochemistry, engineering, and industrial manufacturing, which can be leveraged for this transition.
Conclusion
With fertilizers, Europe's energy and food sovereignty are closely linked. By investing in innovation in fertiliser production, Europe can reduce exposure to volatile gas markets, strengthen its industrial base, and build a more resilient food system. This effort can also drive the global transition to cleaner industrial processes. Europe's next "Haber-Bosch moment" is within reach, offering an opportunity to lead in sustainable agriculture and industrial innovation.
