VK Arora of KPI examines the technical and operational challenges of decarbonising legacy and new ammonia plants, drawing on a European case study of full-scale conversion supported by robust process and integration design. It also presents three US case studies exploring partial strategies, such as green hydrogen blending and oxygen enrichment, to reduce CO2 emissions and improve throughput. Together, these examples highlight a phased, cost-effective approach to decarbonisation, with blue hydrogen serving as a near-term transitional feedstock.

Casale is specialised in revamping natural gas-based methanol plants. Decarbonisation of methanol plants is a goal for many producers achievable with a proper revamping strategy. Pietro Moreo of Casale discusses how Casale’s innovative technologies and extensive experience ensure reliable efficient capacity and performance enhancements together with CO2 emissions reduction tailored to meet revamping project targets.

The production of methanol from waste offers a groundbreaking solution for sustainable urban waste management as well as producing an alternative renewable fuel for maritime transport. Giacomo Rispoli, Andrea Angeletti and Alessia Borgogna of Nextchem provide an overview of the waste conversion process and its application.

No longer viewed as only a chemical feedstock, methanol is increasingly being regarded as a low-carbon energy carrier. Zinovia Skoufa of Johnson Matthey discusses the role of sustainable methanol as a multi-pathway fuel for the energy transition.

By combining oxygen-blown Lurgi™ autothermal reforming (ATR) technology with Cryocap™ H2 carbon capture technology, Air Liquide offers an innovative plant configuration to meet the need for a central production facility offering flexible product diversification with hydrogen and ammonia at a scale that satisfies extensive decarbonisation targets.

Japan’s Marubeni Corporation has secured a long-term offtake agreement from Envision Energy for green ammonia from Inner Mongolia.

OCP Group subsidiary OCP Nutricrops has announced a major investment to expand its phosphate fertilizer production capacity by nine million tonnes by 2028.

CF Industries is planning to construct the world’s largest low-carbon ammonia plant in Louisiana as part of a joint venture (JV) with Jera and Mitsui.

ATOME has signed a definitive engineering, procurement and construction (EPC) contract with Casale for its Villeta project in Paraguay.

TotalEnergies has signed an agreement with the German developer RWE to supply 30,000 t/a of green hydrogen to the Leuna refinery for fifteen years, beginning in 2030. The green hydrogen will be produced by a 300 MW electrolyser, built and operated by RWE in Lingen. Green hydrogen storage will be provided locally. The green hydrogen will be delivered by a 600 km pipeline to the gates of the refinery and will prevent the site’s emission of some 300,000 tons of CO2 beginning in 2030. This is the largest quantity of green hydrogen ever contracted from an electrolyser in Germany.
