Japan Burns More Coal, Courts Russian Crude and Bets on Batteries as Qatar LNG Gap Widens

Japan's coal-fired generation rose 11.1% year-on-year in April as the country burns through its options for replacing Qatari LNG. By early May, the increase had steepened to 18.3%, with gas-based electricity down 23.4% through May 10. South Korea moved faster still: coal generation surged 39.7% in April to 10,733 GWh, the largest single-month jump since August 2019. The proximate cause is Iran's attack on Qatar's Ras Laffan complex in late February, which knocked out roughly 12.8 million tonnes of annual LNG capacity — about 17% of Qatari exports. QatarEnergy invoked force majeure on long-term contracts. Repair estimates run three to five years. Asian spot LNG has roughly doubled since the attacks, with JKM settling at $18.96 per million Btu on May 19. Newcastle coal is up 12-13% over the same period, which tells you buyers are paying up on both fuels. To extend coal capacity, Japan suspended its 50% utilisation cap on inefficient coal plants for one year through March 2027. METI estimates the waiver saves approximately 0.7 billion cubic metres of LNG. Japanese LNG inventories for power generation stood at around 2.30 million tonnes as of mid-June, roughly 0.35 million tonnes above the five-year average — a buffer, but not a comfortable one given QatarEnergy's force majeure position. The longer-term bet is storage. Energy Vault Holdings signed a binding agreement to acquire 350 MW of battery storage projects in Japan, targeting construction in the second half of 2027 and commercial operations in 2028. The company's stock rose 31% in the week ending May 18. Energy Vault also secured a 4 GWh deal with South Africa's Eskom in the same period. The Japan pipeline is tied to data centre demand, not crisis response — but the two dynamics are feeding the same grid pressure. The most politically sensitive development is the Russian crude reopening. Taiyo Oil and Idemitsu Kosan resumed Sakhalin-2 purchases in early May, and a METI delegation is planning talks in Moscow — the most direct engagement since the 2022 invasion. The timing is awkward: the US temporary sanctions waiver on Russian oil expired May 16 without renewal, leaving Japanese refiners in a grey zone on legal exposure. Whether METI's visit produces a bilateral exemption arrangement will determine whether the Sakhalin resumption holds. Brent settled at $110.95 on May 19, WTI at $103.89. European TTF traded at €46.26 on May 20, reflecting Asian competition for non-Gulf LNG cargoes across the Atlantic basin. The key signals for the next two to four weeks: any QatarEnergy statement on Ras Laffan repair timelines, Japan's mid-May coal generation data to confirm whether the early-month acceleration continued, and the outcome of METI's Moscow visit. If no bilateral carve-out materialises on Russian crude, Japanese refiners face an uncomfortable choice between supply security and sanctions compliance before summer demand peaks.
