Mitsui Targets LNG Equity Stakes as Data Center Demand Reshapes Supply Race
Japan's Mitsui is hunting LNG equity deals across the Middle East, US and Australia as AI data centers lock in long-term power supply.
Mitsui & Co. is scouting equity stakes in LNG projects across the Middle East, the US and Australia, its chief executive said in late May (2026-05-31), as the Japanese trading house positions itself to serve surging electricity demand from data centers. The company will look for either equity participation or long-term offtake agreements, with a 15-year supply deal already secured by REalloys, a data center developer.4,5
The move signals how profoundly the AI boom is reshaping LNG contracting. Data center operators need firm, decades-long power supply, and Japanese trading houses like Mitsui are the natural intermediaries between those buyers and upstream gas developers who need capital commitments before final investment decisions.5
But Mitsui is entering a market where the supply map is shifting under everyone's feet. US LNG has become the dominant marginal supplier to global markets, yet European buyers are holding back from locking in long-term contracts with American exporters. That reluctance persists even as the EU phases out Russian gas imports and the Middle East faces supply disruptions, leaving a gap that Asian traders like Mitsui are eager to fill.6,7
The timing is awkward for Europe. EU countries paid Russia EUR 2.9bn for roughly 5.1 million tonnes of LNG in the first quarter, up from 4.3 million tonnes a year earlier, according to environmental group Urgewald. The group said on Friday (2026-05-15) that 97% of all Yamal Arctic LNG deliveries in Q1 2026 went to the EU, calling Europe "the indispensable market" for Russia's flagship LNG project.1
That flow could become a political target. European buyers are trimming their dependence on Russian gas, but the physical reality is that Yamal's Atlantic-basin output has few other destinations, and European regasification terminals remain the most economical outlet. Urgewald describes the purchases as a EUR 2.9bn windfall for the Kremlin.1
Meanwhile, Moscow is pushing east. Russia and China have signed a legally binding memorandum to build the 2,600-kilometer Power of Siberia 2 pipeline, which would carry up to 50 bcm annually from Russia's Yamal Peninsula to northern China via eastern Mongolia. If completed, China could be importing over 100 bcm of Russian gas after 2030, more than one-fifth of its projected demand.2,3
Price has always been the stumbling block. The $400 billion Power of Siberia 1 deal took a decade to negotiate, with China concluding it in May 2014 following Russia's annexation of Crimea. That pipeline reached its target of 38 bcm annually, and now Beijing is negotiating from a stronger position for PS-2, with leverage that Moscow's lost European markets do little to offset.2
China imported 79 million tonnes of LNG and 71 bcm of pipeline gas in 2024. A fully built PS-2 would shift a significant portion of that import mix toward Russian pipeline gas, potentially squeezing LNG demand growth in the world's largest import market and pressuring JKM pricing.2
For Mitsui, the calculus is straightforward. Asian LNG demand is anchored by Chinese and Indian buying, but the growth story that justifies new equity positions is now data centers, particularly in Japan and Southeast Asia where power grids are tightening. The company's willingness to take equity risk in the Middle East, US and Australia suggests it sees LNG demand as structurally stronger than spot prices indicate.5,4
The risk is that Mitsui is buying into a market where the marginal buyer is becoming more cautious. European utilities are wary of US LNG dependence, and China's pipeline optionality gives it less urgency to sign new LNG contracts. If PS-2 moves forward, Asian LNG demand could soften precisely when new US and Qatari supply comes online.2,6
What to watch: whether Mitsui's equity hunt produces a deal in the US, where the political and trade environment has become less predictable, or in Australia, where Woodside and Santos face growing pressure from domestic gas reservation policies. A Mitsui commitment in any of the three regions would be a clear signal that Japanese capital sees data center power demand as a multi-decade structural story, not a cyclical blip.5
