Mitsubishi Corp., Tokyo, said on Sept. 21 it plans a 1 million mt/y blue fuel ammonia plant that will supply product to the Japanese market. The plant, which will be located somewhere near Denbury Inc.’s Green CO2 pipeline between Donaldsonville, La., to west of Houston, is expected to start up in the late 2020s.
Mitsubishi said it is taking steps to introduce fuel ammonia to Japan and develop a fuel ammonia supply chain to the country. The Japanese Ministry of Economy, Trade, and Industry this year released a Road Map for Fuel Ammonia introduction that assumes fuel ammonia imports of 3 million mt/y in 2030, with demand rising to 30 million mt/y in 2050.
Plano, Texas-based Denbury will supply CO2 transport and storage options for the ammonia plant. The estimated CO2 volume to be captured from the ammonia facility is a maximum 1.8 million mt/y. The captured CO2 will be either sequestered underground via Denbury’s enhanced oil recovery or go into carbon capture and storage (CCS), which Denbury plans to develop in the future.
The CO2 term sheet contemplates an initial period of 20 years, with the ability to extend further. Denbury said its CO2 capabilities and assets rank among the world’s largest, and that it has been active in the U.S. Gulf region for two decades.
Earlier this month, Mitsubishi and Shell Canada Products, Calgary, signed a Memorandum of Understanding (MOU) relating to the production of low-carbon hydrogen through the use of CCS near Edmonton, Alberta. Mitsubishi aims to build and start up a blue hydrogen facility near the Shell Energy and Chemicals Park Scotford towards the latter half of this decade, with Shell providing CO2 storage via the proposed Polaris CCS project. The hydrogen would be produced via a natural gas feedstock and exported mainly to the Japanese market to produce clean energy.
The first phase of the project aims to produce approximately 165,000 mt/y of hydrogen with an upside to increase production, depending on considerations over future phases. The hydrogen would be converted to blue ammonia for export to Asian markets.
The project would be built near the Edmonton region, which this year was announced as Canada’s first hydrogen hub. The location was chosen due to availability of abundant natural gas resources, proven CO2 storage capacity, and shared infrastructure opportunities. By co-locating next to Shell Scotford, both companies will explore potential synergies such as land use and utilities integration.
