From Projects to Production: Analyzing Mitsui’s Commercial-Scale Low-Carbon Ammonia Push

Mitsui & Co. has decisively accelerated its low-carbon ammonia strategy from strategic planning to commercial-scale execution, validating the fuel’s role as a cornerstone of its energy transition portfolio. The company’s progression demonstrates a clear shift from establishing initial agreements to deploying billions in capital for world-scale production facilities. This pivot confirms ammonia’s strategic importance as a hydrogen carrier and a decarbonized fuel for power generation and maritime shipping, particularly for its home market of Japan.

• In the 2021–2024 period, Mitsui focused on forming foundational partnerships, such as the November 2021 agreement with TA’ZIZ and Fertiglobe to develop a world-scale, 1 million tons per year blue ammonia project in the UAE. This phase was characterized by memoranda of understanding and feasibility studies, culminating in the start of construction in June 2024.
• The year 2025 marks a significant escalation with the April 2025 joint venture with CF Industries and JERA to develop one of the world’s largest low-carbon ammonia plants on the U.S. Gulf Coast. This represents a massive $4 billion investment decision, moving beyond construction announcements to a financial commitment that underpins a major new export hub.
• This strategic acceleration from the Middle East to the U.S. highlights Mitsui’s intent to build a resilient, geographically diverse supply chain. The U.S. project, backed by a substantial loan, directly supports Japan’s national strategy to secure decarbonized energy resources, positioning Mitsui as a key enabler of its country’s energy security.

Geographic Pivot: How Mitsui is Building a U.S. Gulf Coast Ammonia Hub

Mitsui is strategically establishing two major low-carbon ammonia production and export hubs in the U.S. Gulf Coast and the UAE, creating a powerful pincer movement to serve key import markets in Asia and Europe. This dual-hub strategy diversifies geographic and political risk while capitalizing on the unique advantages of each region. The company is deliberately building a global supply network to dominate future trade flows of decarbonized fuels.

• The 2021-2024 period saw Mitsui establish its foundational production base in the Middle East through the TA’ZIZ partnership in Abu Dhabi. This move leveraged the region’s abundant, low-cost natural gas and its strategic location for supplying Asian markets.
• A definitive geographic pivot occurred in 2025 with the massive commitment to the U.S. Gulf Coast, specifically Louisiana, for the $4 billion project with CF Industries and JERA. This decision was driven by the region’s world-class gas infrastructure, favorable geology for carbon sequestration, and powerful policy incentives from the U.S. Inflation Reduction Act (IRA).
• This two-pronged approach provides critical supply chain resilience. The U.S. hub is perfectly positioned for transatlantic exports to Europe and transpacific shipments to Asia, while the UAE hub efficiently serves the rapidly growing energy demand across the Indo-Pacific.

From Blueprint to Reality: Mitsui Validates Commercial-Scale Blue Ammonia Production

Mitsui has successfully advanced low-carbon ammonia from the conceptual phase to commercial-scale construction, cementing “blue” ammonia—produced from natural gas with carbon capture—as the most bankable and scalable pathway for near-term decarbonization. While maintaining a clear focus on blue ammonia for its flagship projects, the company is simultaneously investing in “green” technologies to ensure its long-term competitiveness as the energy transition evolves.

• Between 2021 and 2024, Mitsui’s activity was centered on feasibility studies and securing partnerships for blue ammonia, as seen with the TA’ZIZ project agreement. The technology was commercially understood, but its application for large-scale, low-carbon export had not yet been financially committed to by the company.
• The period from mid-2024 into 2025 marks a crucial validation point, with construction starting on the UAE project and a final investment decision on the even larger U.S. facility. This shift from planning to pouring concrete signals that blue ammonia has moved firmly into the commercial deployment phase, with its economics and technical risks deemed manageable.
• Despite the strong focus on blue ammonia, Mitsui’s strategic investment in electrolyzer company Power to Hydrogen in March 2025 is a calculated hedge. It provides a foothold in the green hydrogen value chain, positioning Mitsui to pivot or integrate green ammonia production as electrolyzer costs fall and renewable energy becomes more abundant.

What’s Next for Mitsui’s Ammonia Ambitions: Securing Offtake and Expanding the Hydrogen Value Chain

Mitsui’s immediate priority is to de-risk its immense capital exposure in ammonia by securing a diversified portfolio of long-term offtake agreements, while strategically expanding its investments across the broader hydrogen value chain. The company’s recent actions signal a clear intent to move beyond being just a producer to becoming an integrated manager of the entire clean fuel ecosystem, from production and storage to final delivery and use.

• The successful construction and commissioning of the $4 billion Louisiana plant with CF Industries and JERA will be the most critical development to monitor. Its on-time, on-budget delivery will serve as the definitive industry benchmark for executing world-scale blue ammonia projects and will solidify Mitsui’s leadership position.
• Expect Mitsui to aggressively pursue and announce additional long-term offtake agreements for the ammonia produced in both its U.S. and UAE hubs. The company will look to sign deals with maritime and industrial players in Europe and Asia to diversify its customer base beyond its own partners.
• Watch for follow-on investments in adjacent technologies that create a closed-loop system for its ammonia. This includes further stakes in ammonia-fueled engine technologies, advanced storage and transportation infrastructure, and more efficient electrolyzers that build upon its March 2025 investment in Power to Hydrogen.
