Consortium to study potential “blue” ammonia value chain between Siberia and Japan

By Mary Page Bailey |

Toyo Engineering Corp. (Tokyo), Irkutsk Oil Company (IOC), Japan Oil, Gas and Metals National Corp. (JOGMEC) and Itochu Corp. agreed on a joint feasibility study related to the development of the blue ammonia value chain between eastern Siberia and Japan. Blue ammonia is CO2-free ammonia produced by conventional ammonia production processes with CCS (CO2 capture and storage) to isolate CO2 into underground reservoirs

The project aims to establish a future blue ammonia value chain at a commercial scale. Ammonia is liquefied under relatively mild conditions, (around –33 deg. C) in ambient pressure, or 8.5 atm in ambient temperature. Since this condition is similar to that of Liquefied Petroleum Gas (LPG) liquefaction, ammonia can be stored and transported with similar infrastructure for LPG storage and transportation. Ammonia is expected to be used as fuel for power plants that require huge amount of energy. The parties are willing to prepare a new option for energy security between Russia and Japan by establishing a new value chain which transports ammonia produced in Russia to be utilized as fuel in Japan.

Based on the MOU signed by IOC and JOGMEC, JOGMEC initiated the feasibility study of the value chain to transport ammonia to be converted from hydrogen produced by IOC in eastern Siberia, from Russia to Japan by entrusting TOYO and ITOCHU.

As the next step, IOC and JOGMEC plan to conduct a study on blue ammonia production system that combines conventional ammonia production from natural gas and CO2 capture technology, whereas the captured CO2 will be utilized for CO2-EOR*. By realizing the blue ammonia production system and value chain, mass-produced blue ammonia can be stably supplied to Japan and available as fuel for power plants.

Toyo, IOC, JOGMEC and ITOCHU will contribute to establish blue ammonia value chain between eastern Siberia and Japan through close collaboration among the parties by utilizing the technologies and knowledge owned and promoting initiatives to reduce GHGs* by introducing blue ammonia as fuel.
