100 Years Of Ammonia Synthesis: How A Single Patent Changed The World

Summary:
Now it is time to invent sustainable solutions to avoid environmental damage. As a result of the Haber-Bosch process for the synthesis of ammonia from atmospheric nitrogen, billions of people have been fed, millions have died in armed conflict and a cascade of environmental changes has been set in motion, suggests a new article.

As a result of the Haber-Bosch process for the synthesis of ammonia from atmospheric nitrogen, billions of people have been fed, millions have died in armed conflict and a cascade of environmental changes has been set in motion, suggests a feature article by scientists from four of the world’s leading environmental research centres that will be published online on 28 September in Nature Geoscience.

The feature appears 100 years after Fritz Haber filed his patent on the ‘synthesis of ammonia from its elements’ for which he was later awarded the 1918 Nobel Prize in Chemistry.

Lead author, Jan Willem Erisman from the Energy research Centre of the Netherlands (ECN), explains: “The increasing demand for food and biofuels makes efficient use of nitrogen fertilizer and more sustainable energy a challenge for many. Haber-Bosch is perhaps the most significant invention of the 20th Century, yet it has many side effects. Now we need a new invention that changes the world just as much, but without the environmental impact.”

According to the article, we now live in a world transformed by, and highly dependent upon, Haber-Bosch nitrogen. This extra nitrogen has allowed large scale production of explosives with the result of millions of casualties. On the other hand, it has created an enormous chemical industry producing materials and goods for society. The major impact, however, has been the large scale production of fertilizers supporting almost half of the world's population through increased food production.

While the use of nitrogen as a fertilizer has brought enormous benefits, losses of fertilizer nitrogen to the environment lead to many side effects. These include reduced biodiversity and the formation of marine algal blooms. Nitrogen compounds endanger the quality of drinking water, and contribute to air pollution as well as climate change, affecting life quality and the health of large parts of the population.

Future scenarios suggest that such problems will become more extreme, with a potential doubling of fertilizer use predicted over the coming century. This demand is partly driven by the growing requirement for ‘nitrogen hungry’ biofuels. These environmental challenges highlight the need for a new invention, as transforming as the Haber-Bosch process that would benefit both society and the global environment.

The feature concludes by arguing that today’s society is dependent on a nitrogen-based economy and discusses some of the challenges we are likely to face in the next 100 years.

The global nitrogen challenge is an issue that is set to receive more attention in the future. For example, the European Commission is funding the NitroEurope project, a consortium of over 60 research institutions, which is investigating the effect of nitrogen on global warming. Its results will feed into the work of the ‘Task Force on Reactive Nitrogen’, recently established by the United Nations Economic Commission for Europe (UN-ECE).

Mark Sutton from the UK’s Centre for Ecology & Hydrology, who is co-chair of the UN-ECE Task Force and one of the feature’s authors, commented: “It is remarkable how a century of Haber-Bosch nitrogen has transformed all our lives. Without it, half of us might not be alive today. At the same time, the environmental impacts of nitrogen cut across all global change issues. To reduce these effects, we must improve nitrogen use efficiency, especially in food production.”

The research programme of Erisman and colleagues at ECN further highlights the role of bioenergy in the nitrogen cycle. ECN is developing second generation technology for bioenergy and biofuels that will contribute to limiting fertilizer use in the future.
