Reduce carbon emissions with green ammonia

Process technologies and catalysts for production of green ammonia from renewable sources

Apart from being used for fertilizer to feed the world, ammonia has another great potential – when produced sustainably, it can become an emission-free green fuel or be used as energy storage and carrier.

Topsoe has developed process technologies and catalysts for production of green ammonia from renewable sources – wind, water, and air. With the proven track record in the industry and a deep understanding of the science behind ammonia, we are your trusted partner, delivering highly efficient solutions for a robust and highly flexible ammonia synthesis operation.

Hybrid ammonia production
Efficiently integrating green ammonia into existing hydrocarbon-based facilities without jeopardizing plant reliability and yield is not only possible but also lucrative.

Ammonia producers can revamp their existing ammonia plants into hybrid plants using Topsoe’s patented solution where implementation of water electrolysis can produce up to 10% green ammonia with minimal changes to the existing plant. And when the market demand for green ammonia increases, any existing ammonia plant can be further revamped above 10% green production.

With our patented green ammonia solutions, established fertilizer producers can tap into the new green ammonia market and maintain current production capacity while adding green ammonia to the mix.

Green ammonia entirely from renewable sources
Topsoe has developed process technologies and catalysts for production of green ammonia entirely from renewable sources – wind, water, and air. Over the past 70 years, Topsoe has earned a reputation for being a trusted supplier to the ammonia industry. We provide unmatched insight into how to operate a dynamic ammonia production powered directly by solar and wind power.

By leveraging the latest technologies, we can prepare your plant and business for renewable future.

Ammonfuel report

In August 2020, Alfa Laval, Hafnia, Haldor Topsoe, Vestas, and Siemens Gamesa issued the report “Ammonfuel – an industrial view of ammonia as a marine fuel” based on own industrial expertise and input from a list of competent industrial players.

FAQ — green ammonia

What does dynamic mean? How fast can ammonia plant react on hydrogen profiles (e.g. from electrolysis production linked to a wind farm)?
Haldor Topsoe has filed a patent application of an invention for how a green ammonia plant can be designed with a constant loop pressure in dynamic operation that can accept any fluctuations from very low load to full load with a minimum hydrogen storage or no storage at all. Avoiding highly expensive hydrogen storages will of course make the green ammonia plants more economically feasible and safer.

Dynamic means constant synthesis loop pressure for the full operating range 10-100%. It can react to any change in hydrogen production from the electrolyzers.

In terms of using ammonia for maritime usage, will there need to be major retrofitting for NOx control or is there a prediction that fuel cells will be used instead of combustion?
By 2024, the ammonia engines (Internal Combustion Engines) will be available from MAN ES. NOx will be reduced to low level by deNOx, which is already referenced by MAN ES and Haldor Topsoe. More information can be found in our Ammonfuel report.

What is your opinion on green methanol and which one will become more prevalent in the future (ammonia economy vs. methanol economy)?
There will be a market for both green methanol and green ammonia depending on the use or market. The lowest cost green fuel will be green ammonia. Topsoe has technology solutions for both methanol and ammonia as well as other eFuels such as gasoline, diesel, and jet-fuel.

How high does a future CO2 tax need to be to make green ammonia competitive for marine use?
Please access the Ammonfuel report for cost and energy consumption for green ammonia. CO2 taxes are being discussed but there are uncertainties on when and how much. Haldor Topsoe is providing information to support the decision maker.

Many existing ammonia producers face the challenge of upcoming regulatory requirements for reduced carbon emissions. In itself, this adds uncertainty to the business of ammonia producers, and the fact that regulatory demands most likely will be different from region to region only makes forecasting more difficult. Ammonia producers will be less competitive when forced to reduce CO2 emissions. However, this threat can be turned into an opportunity.
