Hokkaido mulls hydrogen, ammonia use at Japan gas units

Japan's northernmost utility Hokkaido Electric Power is considering using hydrogen or ammonia at its planned two combined-cycle gas-turbine (CCGT) units at the Ishikariwan-Shinko power plant, to help achieve the country's 2050 decarbonisation goal.

Hokkaido has decided to postpone the start-up of the two 569.4MW CCGT units at Ishikariwan-Shinko to study the possibility of burning hydrogen and ammonia at the new facilities. The company now targets commissioning the No.2 unit in December 2030 and No.3 unit in December 2035, pushed back from December 2026 and December 2030, respectively.

Hokkaido currently operates only one gas-fired power unit, the 569.4MW No.1 Ishikariwan-Shinko CCGT unit. The delay in the start-up of the other two CCGT units will cap the company's LNG demand at current levels over the next four years at least. Hokkaido consumed 359,000t of LNG from April-December 2020.

The Japanese government has been aggressively promoting the use of hydrogen and ammonia, as part of its action plan to achieve its 2050 carbon-neutral goal. The country's potential hydrogen demand is estimated at a maximum of 3mn t/yr in 2030, with ammonia use also targeted at 3mn t/yr in the same year.

Japanese energy firm Iwatani yesterday announced it would launch a study into developing a large-scale blue hydrogen production and supply chain project using untapped brown coal resources on Hokkaido island. But it is unclear if Iwatani and Hokkaido will work together on a hydrogen project in the future.

Cop: Drafts point to trade-off on finance, fossil fuels

Baku, 22 November (Argus) — The new draft on the climate finance goal from the UN Cop 29 climate summit presidency has developed nations contributing $250bn/yr by 2035, while language on fossil fuels has been dropped, indicating work towards a compromise on these two central issues. There is no mention of fossil fuels in either the new draft text on the global stocktake — which follows up the outcome of Cop 28 last year, including "transitioning away" from fossil fuels — or in the new draft for the climate finance goal. Developed countries wanted a reference to moving away from fossil fuels included, indicating that not having one would be a red line. The new draft text on the climate finance goal would mark a substantial compromise for developing countries, with non-profit WRI noting that this is "the bridging text". Parties are negotiating the next iteration of the $100bn/yr that developed countries agreed to deliver to developing nations over 2020-25 — known as the new collective quantified goal (NCQG). The new draft sets out a figure of $250bn/yr by 2035, "from a wide variety of sources, public and private, bilateral and multilateral, including alternative sources". It also notes that developed countries will "take the lead". It sets out that the finance could come from multilateral development banks (MDBs) too. "It has been a significant lift over the past decade to meet the prior, smaller goal... $250bn will require even more ambition and extraordinary reach," a US official said. "This goal will need to be supported by ambitious bilateral action, MDB contributions and efforts to better mobilise private finance, among other critical factors," the official added. India had indicated earlier this week that the country was seeking around $600bn/yr for a public finance layer from developed countries. Developing countries had been asking for $1.3 trillion/yr in climate finance from developed countries, a sum which the new text instead calls for "all actors" to work toward. The draft text acknowledges the need to "enable the scaling up of financing… from all public and private sources" to that figure. On the contributor base — which developed countries have long pushed to expand — the text indicates that climate finance contributions from developing countries could supplement the finance goal. It is unclear how this language will land with developing nations. China yesterday reiterated that "the voluntary support" of the global south is not part of the goal. The global stocktake draft largely focuses on the initiatives set out by the Cop 29 presidency, on enhancing power grids and energy storage, though it does stress the "urgent need for accelerated implementation of domestic mitigation measures". It dropped a previous option, opposed by Saudi Arabia, that mentioned actions aimed at "transitioning away from fossil fuels". Mitigation, or cutting emissions, and climate finance have been the overriding issues at Cop 29. Developing countries have long said they cannot decarbonise or implement an energy transition without adequate finance. Developed countries are calling for substantially stronger global action on emissions reduction.

Bangladesh issues new phosphate tenders

London, 22 November (Argus) — Bangladesh's ministry of agriculture has issued a new private-sector tender to buy DAP and TSP, closing on 27 November. The ministry did not specify the total quantities sought but specified that each private importer can offer a maximum of 30,000t of TSP and 40,000t of DAP in the tender. The cargoes offered under the tender are to be shipped by 30 December, and nominated importers must issue letters of credit within seven working days of receiving the work order. The ministry closed a private-sector tender to buy DAP and TSP on 18 November and has probably awarded at least 40,000t of Moroccan DAP at $678.40/t cfr in the tender. It had received offers for 120,000t of DAP at prices ranging from $678.40-711.00/t cfr and 113,000t of TSP at prices ranging from $561.90-585.00/t cfr. BCIC seeks 10,000t of phosphoric acid in tender Bangladeshi state-owned importer BCIC has issued a fresh tender to buy 10,000t of phosphoric acid containing 52-54pc P2O5, closing on 8 January. It wants the cargo to be shipped within 30 days of issuing the letter of credit for delivery to Chattogram. Trading firm Sun International submitted the only offer in BCIC's 20 November tender for 20,000t of the same grade of acid. It offered South African or Chinese acid at $620.87/t cfr (equivalent to $1,150-1,194/t P2O5 cfr), or $530.87/t fob. In its 18 November tender to buy 10,000t of 52-54pc P2O5 acid, BCIC received offers of $1,163-1,213/t P2O5 cfr equivalent.

Japan’s Taketoyo to resume biomass co-firing in 2027

Tokyo, 22 November (Argus) — Japan's largest electricity producer Jera aims to resume coal and biomass co-firing at the 1.1GW Taketoyo plant in 2027's first quarter, after a fire halted plant operations in January. Jera announced on 22 November that the thermal power plant in central Japan's Aichi prefecture would resume co-firing wood pellets with coal at a rate of 8pc, around the end of the 2026-27 fiscal year ending in March. This will come after its safety measures are completed. The plant's co-firing rate was 17pc before the serious fire, which was caused by an explosion of dust from wood pellets. The company will consider increasing the co-firing rate again in the future, provided safety can be ensured. But the plant will restart coal-only combustion in early January 2025, operating mainly during the summer and winter seasons, when electricity demand is high. Jera will keep operation rates low at Taketoyo and other coal-fired plants when electricity demand is low and rely more on gas-fired generation, to achieve its initial plan to cut CO2 emissions through co-firing at Taketoyo. Taketoyo started co-firing operations in August 2022 and burned around 500,000 t/yr of wood pellets imported from the US and Vietnam. It will burn 200,000 t/yr after it resumes co-firing at 8pc. The plant will slow down the speed of wood pellet conveyors to reduce friction as a part of safety measures, which means it must also reduce its coal and biomass co-firing rate. It is also currently working on other safety measures, such as installing air pressure conveying facilities dedicated to wood pellets and explosion suppressor systems to inject fire extinguishing agents. The outage at Taketoyo has encouraged Jera to boost replacement gas-fired generation, with the extra gas-fired costs accounting for most of the estimated cost resulting from the shutdown, which could be tens of billion yen in the 2024-25 fiscal year ending in March.

Cost of government support for fossil fuels still high

Cost of government support for fossil fuels still high

London, 21 November (Argus) — The cost of government measures to support the consumption and production of fossil fuels dropped by almost a third last year as energy prices declined from record highs in 2022, according to a new report published today by the OECD. But the level of fiscal support remained higher than the historical average despite government pledges to reduce carbon emissions. In an analysis of 82 economies, data from the OECD and the IEA found that government support for fossil fuels fell to an estimated $1.1 trillion in 2023 from $1.6 trillion a year earlier. Although energy prices were lower last year than in 2022, countries maintained various fiscal measures to both stimulate fossil fuel production and reduce the burden of high energy costs for consumers, the OECD said. The measures are in the form of direct payments by governments to individual recipients, tax concessions and price support. The latter includes "direct price regulation, pricing formulas, border controls or taxes, and domestic purchase or supply mandates", the OECD said. These government interventions come at a large financial cost and increase carbon emissions, undermining the net-zero transition, the report said. Of the estimated $1.1 trillion of support, direct transfers and tax concessions accounted for $514.1bn, up from $503.7bn in 2022. Transfers amounted to $269.8bn, making them more costly than tax concessions of $244.3bn. Some 90pc of the transfers were to support consumption by households and companies, the rest was to support producers. The residential sector benefited from a 22pc increase from a year earlier, and support to manufacturers and industry increased by 14pc. But the majority of fuel consumption measures are untargeted, and support largely does not land where it is needed, the OECD said. The "under-pricing" of fossil fuels amounted to $616.4bn last year, around half of the 2022 level, the report said. "Benchmark prices (based on energy supply costs) eased, particularly for natural gas, thereby decreasing the difference between the subsidised end-user prices and the benchmark prices," it said. In terms of individual fossil fuels, the fiscal cost of support for coal fell the most, to $27.7bn in 2023 from $43.5bn a year earlier. The cost of support for natural gas has grown steadily in recent years, amounting to $343bn last year compared with $144bn in 2018. The upward trend is explained by its characterisation as a transition fuel and the disruption of Russian pipeline supplies to Europe, the report said.

Investment funds’ net long on Ice TTF reaches new high

Investment funds’ net long on Ice TTF reaches new high

London, 21 November (Argus) — Investment funds' net long TTF position on the Intercontinental Exchange (Ice) jumped to a new all-time high earlier this month, outstripping the previous record in late August. The latest weekly data from Ice show investment funds' net long TTF position shot up to a new record at just under 273TWh by 15 November, topping the previous all-time high of roughly 268TWh in the week ending 30 August , revised data show. After peaking in August, the position dropped to 192TWh on 20 September, and held broadly stable before jumping 33.6TWh in the week ending 25 October . TTF prices rose in the following two weeks, but funds trimmed their net long position to around 226TWh on 8 November ( see graph ). But in the most recent week of data from Ice, investment funds' net long position shot up to just under 273TWh by 15 November, a new record high. Over the same period of 8-15 November, The Argus TTF front-month contract rose by more than 9pc, and there were similarly large moves for the first-quarter 2025 and summer 2025 contracts. The calendar 2025 price was also up by 8pc ( see table ). Significant price volatility in recent trading sessions has also prompted Ice to increase margin rates by around 20pc on all contracts out to September 2025 , with smaller increases further down the curve. Austrian incumbent OMV announced this week Russia's Gazprom would halt its contractual supply from 16 November , prompting sizeable day-on-day price moves across Europe and possibly encouraging investment funds to go longer and capitalise on the volatility. But central European flows have changed only slightly since then, with roughly the same amount of Russian gas entering the region. Higher TTF prices have also caused LNG diversions from Asia to Europe in recent days, which reached double digits on 19 November . Such a large net long position suggests investment funds may still expect a tight European gas balance this winter. Record-low freight rates have brought the cost of shipping US LNG to Asia closer to the cost of the shorter US-Europe route, meaning European prices have to rise sufficiently high enough to offset this and close the inter-basin arbitrage again in order to attract uncommitted cargoes. Cold weather has also prompted EU firms to draw down storage stocks heavily so far this month . Aggregate EU withdrawals averaged just under 3 TWh/d on 1-15 November, four times the 756 GWh/d average for that period in 2018-22 and sharply contrasting the 965 GWh/d of net injections across the bloc on 1-15 November 2023. Unlike investment funds, the two other major categories of Ice market participant — commercial undertakings and investment/credit firms — boosted their net short positions by a combined 53TWh, leaving the latter with nearly 200TWh in net shorts, the highest since mid-September. Despite significant storage withdrawals, commercial undertakings ‘risk reduct' contracts — generally used for hedging — in the week to 15 November jumped by just under 30TWh to nearly 211TWh, the highest since 24 December 2021. Some of that increase may have been driven by a need to hedge the LNG cargoes diverted to Europe in recent weeks as European hub prices rose. A 9TWh increase in the net long position of commercial undertakings' other contracts slightly moderated the overall net short increase. The gross short and long positions of commercial undertakings totalled 1.95PWh, nearly twice as large as the investments funds' 646TWh and investment/credit firms' 421TWh combined.
