Cop: Japan to ban building of new unabated coal plants

Japanese prime minister Fumio Kishida has told the UN Cop 28 climate conference that Japan will stop building additional unabated coal-fired power plants.

"Japan will take the path to net zero emissions by ending the construction of new domestic unabated coal power plants, while ensuring stable energy [supplies]," Kishida said on 1 December.

The pledge is in line with the G7 target of fully or predominately decarbonising the power sector by 2035 and achieving net zero emissions by 2050, announced in April.

Japan already has two coal-fired units under construction. The country's largest power operator, Jera, plans to start commercial operations of its 650MW Yokosuka No 2 coal-fired unit in Kanagawa prefecture in February next year. Japanese power producer and wholesaler J-Power aims to build a new 500MW No 2 unit for its Matsushima coal-fired plant in Nagasaki prefecture by the financial year starting in April 2028 to replace two old coal-fired units with a combined capacity of 1GW. The upcoming Matsushima unit is set to have an integrated coal gasification combined-cycle component.

The vow is unlikely to cancel ongoing coal-fired plant projects given that the Yokosuka No 2 unit is near completion, while an environmental impact assessment on the new Matsushima unit began in September 2021. In addition, specifying unabated coal-fired plants in the pledge suggests the Japanese government may continue to allow new coal-fired plants with emissions reduction technology, such as ammonia co-firing.

Japan has operational coal-fired units with a combined generation capacity of about 52GW across the country as of early December, according to Japan Electric Power Exchange.

South Korean elections spark uncertainty for renewables

Singapore, 1 March (Argus) — South Korea's nuclear strategy is likely to stay, regardless of the outcome of its 10 April national assembly elections, although a majority win for the People Power Party (PPP) could further threaten its renewable energy ambitions. South Korea's national assembly elections will take place on 10 April, with neck-and-neck approval ratings so far for the PPP and Democratic Party (DP). Current president Yoon Suk-yeol is from the PPP, although the DP currently holds the majority seat in the national assembly with 163 of the 297 seats. The incumbent Yoon administration has been expanding the domestic nuclear fleet , while at the same time cutting 2030 targets for hydrogen use in power generation . South Korea also recently released a host of measures as it aims to become "the world's nuclear energy powerhouse", with plans to develop 3.3 trillion won ($2.48bn) worth of nuclear power plant projects this year. The country will likely see an even greater emphasis on nuclear power should the PPP take the majority in the general elections, while main rival DP's stance is more in favour of renewable energy and hydrogen, as opposed to nuclear power. South Korea's final 2024 budget seemingly reflects lower prioritisation of its net zero goals , despite the DP making up the majority of the country's legislative body. This is in addition to the country seeking to solidify ties with the key energy-producing Mideast Gulf region , which hints it may likely continue relying on fossil fuels. But South Korea seems largely committed to its hydrogen ambitions, as it continues to improve regulations in the industry this year. The country also previously announced it plans to open a clean hydrogen power generation market early this year . Nuclear emphasis But other factors such as South Korea's push to boost its exports to spur economic growth may continue to underpin South Korea's increasing reliance on nuclear power, also reflected in its lower coal-fired and gas-fired generation in 2023 . Notably, the Yoon administration is currently pushing to advance a South Korean-led global Carbon-Free Energy (CFE) Initiative. This initiative aims to expand all forms of energy sources that do not emit greenhouse gases (GHG), which notably includes nuclear power, as well as hydrogen and carbon capture, utilisation and storage. The country's trade, industry and energy ministry (Motie) has since published a document, in which it addresses speculation that the CFE initiative's aim is to expand nuclear power, stating that it "does not discriminate between renewable and nuclear energy". "What we need is an inclusive approach that can propel our industries to reach the greater goal of carbon neutrality at a minimum cost by utilising a variety of carbon-free energy sources," said Carbon Free Alliance chairperson Lee Hoesung, who is also the former chairperson of the Intergovernmental Panel on Climate Change, in late January. South Korea hopes to see global uptake of the initiative, with 20 major domestic companies currently participating in the CFA. This is in comparison to the RE100 initiative, which only includes renewable energy, but has over 400 global members. It is also worth noting that South Korea's budget for this year is based on boosting exports to spur economic growth, with one of its key exports being nuclear technology and equipment, which is a possible reason why the country would be invested in seeing more uptake of nuclear power globally. Policy continuity South Korea's upcoming general elections are not likely to result in major energy policy changes, even if there is a significant change in the make-up of the National Assembly. But the same cannot be said for the country's presidential elections. DP-affiliated former president Moon Jae-in previously enacted plans to phase out nuclear power during his leadership, with ambitious emissions targets . But the country did a U-turn on its stance on nuclear power when current president Yoon replaced Moon in 2022. This included resuming nuclear reactor construction and raising nuclear capacity, after it was reduced under the previous administration. But Yoon has been in office for about two years and his term only ends in 2027, so the country's policies are likely to stay largely consistent for the foreseeable future, although how they will pan out beyond that remains to be seen.

Germany overhauls gas-fired capacity addition plans

London, 29 February (Argus) — Germany has scaled back plans to add more hydrogen-ready gas-fired capacity towards the end of the decade, but is now likely to allow gas-fired power plants with carbon capture and storage (CCS). German climate and economy ministry BMWK earlier this month announced that it would "shortly" tender for a combined 10GW of hydrogen-ready gas-fired capacity . The gas-fired power plants would have to switch fully to hydrogen between 2035 and 2040, BMWK said, with the final date determined in or after 2032. In a previous draft from August last year , the ministry had outlined plans for 15GW of hydrogen-ready gas-fired plants, in addition to 8.8GW of capacity that would run on hydrogen from the start. But plans for the hydrogen-only plants have been scrapped entirely. Industry representatives have criticised the revised power plant strategy for not providing enough capacity for a quick energy transition. The timing is "very tight" to meet Germany's 2030 coal phase-out goal, German utility Uniper chief executive Michael Lewis said this week. Germany would need 20-25GW to even replace decommissioned power plants, Lewis said. Germany has expanded its gas-fired capacity in recent years as coal and lignite plant shutdowns and the nuclear phase-out partly counteracted renewable capacity additions. The country's gas-fired capacity has risen by a net 5.67GW since 2019, while a net 16.79GW of coal, lignite, and nuclear capacity has been taken off the grid, data from Fraunhofer ISE show ( see graph ). Over the same period, wind and solar additions reached 47.72GW, although renewable assets run at a lower load factor than thermal plants as external weather patterns determine their output. Germany is placing a strong focus on renewable hydrogen in the energy transition and is eyeing imports as well as domestic production, especially in the northern part of the country, which has ample renewable power potential. Renewable hydrogen, produced through electrolysis in times of surplus generation, can be burned in hydrogen-fired power plants to meet base-load and peak demand. CCS at gas-fired power plants In its draft carbon management strategy published earlier this week, BMWK signalled it will allow CCS not only in industrial processes but also in gas-fired power plants, a departure from previous policy. Allowing CCS at gas-fired power plants may open an option for low-carbon dispatchable electricity generation. Germany's energy policy had previously mostly focused on renewables with hydrogen or battery storage, rather than banking on firm low-carbon generation options such as gas-fired generation with CCS or nuclear generation. CCS had been effectively banned in Germany until now, with no legal provisions for CO2 transport and local veto rights for carbon storage sites. And while BMWK last year said it was in "intensive" talks with Norway and Denmark on cross-border CO2 transport and storage, storing carbon in Germany's offshore economic zone was "meeting Germany's responsibilities rather than shifting it onto others", BMWK said. Economy and climate protection minister Robert Habeck called the decisions "pragmatic" and "responsible" as without CCS, Germany's climate targets will be "impossible to reach". But environmentalists have slammed the policy shift. The move could "destroy acceptance for any kind of CCS in Germany" and was carried out "evidently at the instigation" of the pro-business FDP coalition party, which tends to favour technological openness, according to environmental group Germanwatch. Advocates of CCS point to its potentially inevitable use in hard-to-abate industrial sectors such as the cement industry. But BMWK's draft strategy points out that even the most advanced CCS technology is only able to filter 90-95pc of end-of-pipe carbon emissions, making fossil fuel-based CCS a bridging technology towards a zero-carbon power system. While the government will allow CCS in gas-fired power plants, it will provide no financial support for this, and it will not allow coal-fired power plant to access the CO2 grid. The government's strategy makes no mention of low-carbon hydrogen made from natural gas with CCS. Energy-intensive industry association VIK welcomed the government's commitment to "technological openness", highlighting that the market should decide if this technology should be used, which is "in no way certain". The role of CCS in gas-fired power plants will "depend on costs, infrastructure and flexibility of the installations", energy and water association BDEW said.

Indonesia’s PLN raises biomass targets at coal plants

Manila, 29 February (Argus) — Biomass consumption at Indonesia's coal-fired power plants is likely to increase this year, in line with government efforts to cut down greenhouse gas (GHG) emissions from the power sector. PLN Energy Primer Indonesia (PLN EPI) — a PLN unit responsible for ensuring adequate fuel supplies to PLN-owned power plants — said it is aiming to supply 2.56mn t of biomass this year, more than double last year's volume of 1mn t. The higher biomass consumption in the power generation sector is expected to cut GHG emissions by up to 2.8mn t CO2 equivalent (CO2e). Biomass co-firing resulted in an emissions reduction of 1.05mn t in 2023. PLN EPI's biomass supply will come from agricultural, plantation and forestry residue and waste such as sawdust, rice husks, corn cobs, sugar cane bagasse, empty palm fruit pellets, palm shells, candlenut shells, and wood chips. Sourcing a variety of biomass products will allow for higher uptake as it addresses supply constraints that could arise if the types of biomass are limited, the company said. Sourcing is expected to be easier this year following the passage of a ministerial regulation from Indonesia's energy ministry (ESDM) in November 2023, which sets pricing for biomass products meant for power generation. Under the regulation, biomass products sold for power plant use will have a maximum price slightly above the HBA coal reference price, which is set monthly by the ESDM. This will allow power plants to incorporate co-firing without a significant increase in the cost of operations, PLN EPI said. PLN EPI is also expanding its sourcing to include farmers' associations, co-operatives, and community groups with the goal of having each coal-fired plant's biomass needs supplied by local businesses and communities. Biomass sources are currently scattered across the country and relatively far from power plant sites. But bringing biomass sources closer to power plants should stabilise supply, making it easier to implement co-firing at additional plants, PLN EPI said.

Japan eyes potential of summer power demand: Correction

Corrects nuclear generation forecasts in paragraph 3 Tokyo, 27 February (Argus) — Japan faces potential similar consumption of thermal power generation fuels this summer with nuclear availability and forecast temperatures mostly in line with a year earlier. The Japan Meteorological Agency forecasts a 50-70pc probability of temperatures during June-August 2024 rising above the 30-year average in all parts of Japan. Average temperatures in Japan's major cities, such as Tokyo, Osaka and Nagoya, during June-August 2023 were higher than the long-term average. This implies that the country is likely to face similar summer temperatures as last year. Nuclear power output is projected to rise slightly in summer from a year earlier. The operating capacity of nuclear power plants is forecast at an average of 9,595MW during June-August, while average actual operating capacity was 9,563MW in the same period in 2023, according to Argus calculations based on data from Japan's Agency for Natural Resources and Energy and notices on the Japan Electric Power Exchange website. Hotter weather across the country in 2023 failed to lift thermal fuel demand, with power demand in Japan's 10 service areas averaging 104.3GW for June-August, down by 1.2pc from the same period a year earlier, according to nationwide transmission system operator the Organisation for Cross-regional Co-ordination of Transmission Operators. The rainy season normally cuts solar output. But sunlight hours were unusually longer in 2023 compared with 2022, which increased solar output and helped curb thermal generation. Continued energy saving efforts also helped to cut electricity use. Japan's LNG consumption for power generation totalled 9.8mn t during June-August 2023, according to the trade and industry ministry. Coal use totalled 26.5mn t, while oil consumption — including fuel oil, diesel and crude — was 57,651 b/d. LPG use was 6,014t.
