• Focus on green energy/hydrogen export via ammonia

• Opportunities gain traction through political incentives

Two major trends dominate the energy and natural gas market: the high and volatile price of natural gas, and the shift towards renewable energy sources. While some of the most pressing energy needs can be met by LNG imports, there is growing market interest in ammonia as a carrier for green energy and hydrogen.

Lucretia Löscher, COO thyssenkrupp Uhde: “We have conducted numerous feasibility studies for power-to-hydrogen-to-ammonia development projects. Incentive schemes such as the Inflation Reduction Act, H2 Global and Hydrogen Head Start support the competitiveness of these climate-friendly projects.”

thyssenkrupp Uhde’s competence center for green ammonia in Australia supports a broad variety of customers with techno-economic studies and optimization concepts. In total, the studies already conducted would amount to a potential increase of the global production capacity by around 30 million tpa (tons per annum) of green ammonia. To produce the required green hydrogen, electrolyzers with more than 45 gigawatts would need to be installed with varying power supply configurations. The added up capacities from the studies reflect a significant interest in ammonia as an energy vector, and this underlines its importance for shipping green hydrogen and green energy across the globe. This development marks a fundamental diversification of its primary use as a fertilizer feedstock.

Ammonia market becomes sustainable, new markets emerge

As one of the world’s most traded base chemicals, ammonia is today mainly used for fertilizer production, with natural gas as a feedstock. However, more and more producers are looking for alternatives, and there are two main options. The first is 'blue ammonia', which is still produced from natural gas, but with the CO₂ being captured and stored to reduce the carbon footprint as much as possible. The first projects are already underway, and many countries see this as a viable way to improve sustainability in the short term.

In the medium and long term, the green production of ammonia is key for a sustainable world. Only water, air and renewable electricity are needed to produce this high-demand base chemical in a completely emission-free way. As the global infrastructure for handling, storing, and transporting ammonia already exists, green ammonia could be produced in the sunny Gulf States, Australia or other renewable-rich countries and then transported to countries with high demand for renewable energy or hydrogen, such as many European countries. Ammonia has a volumetric energy density nearly 33% higher than liquid hydrogen, making it more efficient and cost-effective to transport. It also liquefies at -33°C, which is easier to achieve and maintain than the near-absolute-zero temperature of -253°C required for hydrogen liquefaction.

Ammonia cracking, or direct use in either power generation or as marine fuel

When green ammonia reaches its destination, it can be converted back into hydrogen by ammonia cracking, a technology which thyssenkrupp Uhde can also provide. This offers an alternative to fossil-based hydrogen and enables sustainable value chains for many chemicals. Even more efficient is the direct use of green ammonia, for example in gas turbines to generate power. This is already being tested in co-firing, and full ammonia turbines are also being developed.

One final point: To make the transport itself sustainable, more and more shipping companies are interested in using green ammonia as a marine fuel. With the exclusive use of green ammonia, the only emissions are nitrogen (the climate-neutral main component of our atmosphere) and water, with no emission of sulfur, soot, fine particulate matter, or C0₂. Ammonia is therefore an excellent way to transport green energy and hydrogen to where it is needed. Technologies are already being developed and applied.

• Joint development of environmentally friendly solution

• Low-emission calcination process enables CO₂ capture in limestone

thyssenkrupp Uhde has signed a master agreement with Ma’aden (Saudi Arabian Mining Company) for the development, engineering and licensing of a calcination plant for phosphogypsum processing. The purpose of the proposed plant, to be located at Ma’aden’s Ras al Khair site in Saudi Arabia, will be to recycle phosphogypsum and enable the capture of CO₂ emissions. The joint research and development will be carried out together with thyssenkrupp Polysius and Metso Outotec.

Hassan Al-Ali, Executive Vice President, Ma’aden Phosphate: “We look forward to working with our partners to develop this unique solution, utilizing our new patented technology to reduce carbon emissions and recycle phosphogypsum into a useful resource. With this ambitious project, we will contribute significantly to the Saudi Green Initiative and create lasting impact in line with our Kingdom’s Vision 2030.”

“We are honored to be chosen by our esteemed customer to provide our technology and expertise,” said Lucretia Löscher, COO thyssenkrupp Uhde. “We are providing the innovative process to turn the phosphate industry into a circular economy. This project will be another important milestone for thyssenkrupp Uhde in enabling the green transformation of our customers.”

Currently, significant amounts of phosphogypsum are produced as a by-product of phosphoric acid production, which is essential for producing phosphate fertilizers. The options for using phosphogypsum directly are very limited due to impurities and the general properties of this material. The innovative phosphogypsum treatment process will have three major benefits: First, it converts phosphogypsum into quicklime (calcium oxide, CaO). By using alternative fuels such as hydrogen or sulfur, this calcination step is low in CO₂ emissions. Additional know-how for this process is provided by thyssenkrupp Polysius, a full range-supplier of the cement and lime industry. Secondly, it enables the recovery of sulphuric acid, which can be recycled and reused as feedstock for phosphoric acid production. And thirdly, the quicklime binds CO₂ through a carbonization process to form limestone. The limestone can then be used, for example, in the construction industry or for cement production.
