The last year has seen the first shipments of low-carbon ‘green’ fertilizers from companies such as Yara, Fertiberia, OCI and Sabic Agri-Nutrients. Partnerships with food manufacturers and retailers are helping to grow this emerging market and drive demand.
Green ammonia production facilities can be situated in remote areas with access to often fully off-grid renewable power supply. This article examines plant concepts and discusses the challenges and solutions for these plant architectures. Through a case study, an efficient and innovative methodology to compare options and optimise the sizing of the plant is presented. The methodology addresses the intermittency of the power production, the flexibility limits of the main process units, and the costs of investment and operation, using proprietary techno-economic dynamic simulation software, Odyssey.
Large-scale ammonia cracking technology and catalysts will enable the full potential of ammonia to be realised as industries transition towards low carbon energy. In this feature we report on the current status of ammonia cracking processes and catalysts.
A summary of papers presented at CRU’s Nitrogen+Syngas conference, this year held at the Gothia Towers in Gothenburg, Sweden.
Join us at CRU Nitrogen + Syngas 2024 in Gothenburg, 4-6 March, for a truly global gathering of the nitrogen and syngas community, where leading producers and technology experts will gather to connect, share knowledge, exchange ideas and learn about the latest developments in operations, technology, process and equipment.
SunGas Renewables Inc. has formed a new subsidiary, Beaver Lake Renewable Energy, LLC (BLRE), to construct a new green methanol production facility in central Louisiana. The project will have a capacity of 400,000 t/a of green methanol, using gasified biomass, specifically wood fibre from local, sustainably-managed forests as feedstock. The methanol will have a negative carbon intensity through sequestration of the nearly 1.0 million t/a of carbon dioxide produced by the project, which will be executed by Denbury Carbon Solutions. The methanol will then be used as a clean marine fuel by A.P. Moller–Maersk, which is building a fleet of methanol-powered container vessels.
Mining, metals and fertilizer business intelligence company CRU has launched a new low-emissions ammonia (LEA) price assessment in its Fertilizer Week price reporting service. The price takes a value-based approach, whereby a premium on the Northwest European ammonia price is calculated on an emissions-mitigated basis, and leverages CRU’s proprietary nitrogen asset emissions data combined with weekly European carbon prices to calculate the value of emissions mitigated. CRU says that it has leveraged its Emissions Analysis Tool to develop the premiums on an emissions-mitigated basis as opposed to a cost basis, allowing end-users to assess how the switch to LEA can deliver value to their business while contributing to their decarbonisation strategies. The Emissions Analysis Tool is a comprehensive asset-byasset emissions dataset for the nitrogen industry.
ExxonMobil has awarded the contract for front-end engineering and design (FEED) of what it describes as the world’s largest low-carbon hydrogen production facility. A final investment decision for the project is expected by 2024, subject to stakeholder support, regulatory permitting, and market conditions. Technip Energies will conduct the FEED for the Baytown integrated complex, which will produce up to 1 bcf/d of low carbon hydrogen, while capturing more than 98% of associated CO2 emissions, totalling around 7 million tCO2 e/year. Offtake agreements are reportedly under discussion with third party customers. Start-up is planned for 2027-2028. The carbon capture and storage network being developed for the project will also be made available for use by third-party CO2 emitters in the area in support of their decarbonisation efforts.
Previously, recuperative reforming has been mostly applied for capacity increase revamps, but nowadays it is a key enabler for efficient low carbon hydrogen and syngas production. Jan-Jaap Riegman of Technip Energies, Francesco Baratto of Casale and Stefan Gebert of Clariant discuss the benefits of recuperative reforming for reducing the carbon footprint of existing assets.
Lithium miner Ioneer Ltd has signed a non-binding Memorandum of Understanding with Shell Canada Energy for the supply of sulphur to Ioneer for its Rhyolite Ridge lithium-boron project in Esmeralda County, Nevada. Ionner said in a statement that “securing the supply of key reagents for ore processing is an important step along the critical pathway to developing the Rhyolite Ridge project”. Under the memorandum, Ioneer will purchase up to 500,000 t/a of high-quality sulphur from Shell, which would fulfil the estimated annual sulphur requirement for the Project.
