Low carbon energy programme Ammonia: zero-carbon fertiliser, fuel and energy store. What is green ammonia? Decarbonisation of ammonia production Reducing the amount of carbon dioxide produced during the ammonia manufacturing process is critical to achieve net-zero targets by The most likely short-term options for creating carbon-free hydrogen at scale are blue hydrogen and green hydrogen: Blue hydrogen is where carbon emissions from the steam methane reforming SMR process are captured and stored CCS.

Green hydrogen is produced using water electrolysis to generate hydrogen and oxygen, using sustainable electricity in the process. This makes it an ideal chemical store for renewable energy. There is an existing distribution network, in which ammonia is stored in large refrigerated tanks and transported around the world by pipes, road tankers and ships.

Zero-carbon fuel — ammonia can be burnt in an engine or used in a fuel cell to produce electricity. The maritime industry is likely to be an early adopter, replacing the use of fuel oil in marine engines. But there is an alternative. At thyssenkrupp Industrial Solutions we developed a technology that can produce green ammonia from just water, air and electricity generated from renewables. The process involved, alkaline water electrolysis AWE , is based on the proven chlor-alkali electrode technology developed by thyssenkrupp Uhde Chlorine Engineers, whose expertise and experience in electrolysis technology and EPC execution are based on more than projects with over 10 GW capacity installed worldwide.

We are a reliable and competent EPC contractor and world market leader for electrolysis and ammonia plants with more than plants built worldwide and over 90 years of experience. Our first green ammonia plant we built in Chile with a capacity of 50 metric tons per day ammonia. Our References. For the production of green ammonia we build on decades of expertise and experience as the world market leader in electrolysis and ammonia plants:.

Our green ammonia process based on AWE technology is an interesting option for greening existing ammonia plants, as the following diagram shows. And in December, the company announced an even larger project: new electrolyzers at its plant in Porsgrunn, Norway, for , t per year of ammonia production. Yara wants to sell the ammonia as a fuel for ships. The company is seeking incentives from the Norwegian government before it moves forward.

CF Industries is launching the first big green ammonia project in the US. The electricity for the plant will be renewable power purchased from the grid.

Moreover, Will says, the market is potentially huge. Many have come from Japan, where power companies are experimenting with cofiring ammonia in coal-based power plants with the aim of converting entirely to ammonia one day. Not everyone is as bullish as Will. Andrea Valentini, a principal for Asia-Pacific and the Middle East at Argus Consulting Services, points to a number of hurdles the industry must clear if it is to establish green ammonia as an alternative fuel.

In one such initiative, the Finnish engine maker Wartsila is beginning this year to test an ammonia-fueled four-stroke marine engine. In another, MAN Energy is perfecting a two-stroke ammonia engine. Other unknowns abound. And where companies see high profit margins for green ammonia, Valentini sees costs. Another question for the green ammonia sector is whether there will be enough renewable power to support it.

Forecasts for renewables are bullish. Related: Trying to make green hydrogen work in Europe. Blue ammonia might offer a quicker and cheaper route to a hydrogen economy, according to Valentini. This could be especially true in North America, where the large oil and gas industry keeps the cost of producing conventional ammonia low and creates opportunities to use carbon dioxide in enhanced oil recovery EOR or to store the greenhouse gas permanently underground.

Indeed, as CF announced its green ammonia project, it also promised to pursue 3. These will be relatively low cost, akin to that of conventional ammonia, Will says, noting that the company already captures CO 2 for urea production.

Little additional capital investment is needed to compress the CO 2 and get it to pipelines for sequestration, Will says. And tax breaks would offset those expenses. A pipeline that serves the EOR market is also nearby. Another fertilizer producer, Nutrien, is also betting on blue ammonia. Experts say blue ammonia is in need of certified industry standards, similar to the distinction the 45Q tax credit makes between CO 2 permanently sequestered or reused. Some shades of blue ammonia are lower carbon than others, and not one is as low carbon as green ammonia.

Ammonia makers hope to have standards in hand by the end of the year. With certification, a premium for blue ammonia would likely emerge. Another approach, called turquoise ammonia, is the path that the start-up Monolith Materials is taking. Last July, the company completed a plant in Hallam, Nebraska, that breaks down natural gas into hydrogen and elemental carbon, a material known to industry as carbon black. Carbon black is sold as a filler for tires and rubber.

The plant started with a capacity of 14, t per year of carbon black. As a follow-up, Monolith is now building a new, , t carbon black plant and will use the coproduct hydrogen to make , t of ammonia.

Making ammonia is a relatively new idea for Monolith. Its original plan was to sell the hydrogen to the Nebraska Public Power District to burn for electricity. But Monolith executives with experience in fertilizers had other ideas when they studied the project. The company has a different model than the green ammonia developers, however. The plant, which sits in the middle of the US Corn Belt, will sell the ammonia as low-carbon fertilizer rather than as fuel.

Valentini, the consultant, continues to be cautious about low-carbon ammonia, but he does see an important sign that the approach might prevail: ammonia makers, end users, and governments seem to want it to succeed and are backing it with real time and money.
