Marubeni signs a long-term offtake agreement for green ammonia
Marubeni has signed a long-term offtake agreement with green technology company Envision Energy Co., Ltd for ammonia produced from renewable energy in Inner Mongolia, China. Marubeni says that it will take a certain volume of green ammonia produced at a plant on a long-term basis and supply it to clients. This project marks Marubeni’s first long-term offtake agreement for green ammonia, via which Marubeni aims to establish its position as a key supplier in the green ammonia market.
Envision plans to begin trial production of green ammonia with wind-generated electricity in Chifeng City, Inner Mongolia. The company’s commercial green ammonia plants are scheduled to start operations from September 2025 onwards, with an initial production capacity of 300,000 t/a in the project’s first phase. Envision is aiming to eventually produce 5 million t/a.
Construction on the Chifeng plant began in April 2023, and Envision started ammonia production in March 2024, as part of an initial exploratory phase to evaluate diverse electrolysis technologies, dynamic ammonia synthesis, and off-grid integration. The company says that it will be capable of supplying substantial volumes of renewable ammonia both domestically and internationally starting from Q4 2025. Following this initial stage, the second phase will double annual production by another 300,000 t/a, with the third phase set to add a further 900,000 t/a. Envision also aims to address electrolytic hydrogen production constraints by developing extensive hydrogen pipeline infrastructure, consisting of an 800 km main pipeline and multiple branches. This network will connect Ordos City in Inner Mongolia to Chifeng City in the East, streamlining hydrogen transport significantly. In addition to hydrogen pipelines, Envision is planning a dedicated 300 km liquid ammonia distribution pipeline from the production facility near Chifeng to Jinzhou Port, where it is developing an ammonia storage terminal and jetty for export purposes.
