Japan pushes abatement approach to energy transition

Japan is keen to promote its energy transition approach, focused on carbon abatement technologies, to the wider coal-reliant Asia-Pacific region.

The country has accelerated development of carbon abatement technologies to keep fossil fuels in its energy mix and boost energy security and economic growth. Japan, with its G7 counterparts, pledged to phase out "unabated" coal-fired plants by 2035, or "in a timeline consistent with keeping a limit of a 1.5°C temperature rise within reach, in line with countries' net zero pathways".

This is a major step for Japan, a resource-poor country. But legislative progress aimed at developing value chains for carbon capture and storage (CCS) and cleaner fuels, such as hydrogen and ammonia, might have encouraged Tokyo to commit, especially since the G7 text allows for some wiggle room.To ensure continued use of its abated thermal power plants, trade and industry ministry has requested ¥11.2bn ($79mn) to support CCS projects, including exploration of CO2 storage sites, for 2025-26, up sharply from the ¥1.2bn budgeted for 2024-25.

Japan has yet to set a date to achieve the phase-out target. But it had already promised not to build new unabated coal-fired plants at last year's UN Cop 28 climate talks, while pledging to phase out "inefficient" coal-fired plants by 2030. Less than 5pc of Japan's operational coal fleet has a planned retirement year, according to analysis by Global Energy Monitor, and these might comprise the oldest and least efficient plants. Coal capacity built in the last decade, following the Fukushima-Daiichi nuclear disaster, is unlikely to receive a retirement date without a countrywide policy that calls for a coal exit.

Japan's coal demand could decline, to some extent, under global divestment pressure. But the fuel remains key, as the government sees renewables and nuclear as insufficient to meet rising power demand driven by the growth of data centres needed to enable artificial intelligence.

Continental divide

The country is keen to extend its vision for "various" and "practical" pathways, including abatement technologies, to coal-reliant southeast Asia. This stems from Tokyo's sceptical view about promoting a more European approach to the energy transition — driven by wind and solar power — to Asian countries. Japan stresses the importance of more diversified pathways, including thermal power with abatement. The country aims to spur decarbonisation in Asia-Pacific through a platform called the Asia Zero Emission Community (Azec) initiated in 2022. Asia-Pacific accounts for more than half of global greenhouse gas (GHG) emissions, at 17.178bn t of CO2 equivalent, according to the IEA.

In Jakarta last month, 11 Azec countries emphasised the need to co-operate "to decarbonise coal power generation". The platform sets out options such as biogas, hydrogen and ammonia, and retrofitting with CCS and carbon capture, utilisation and storage. Japan's industries have already committed to carbon abatement at coal-fired plants in Asia, leveraging their technological know-how.

Tokyo has pledged to provide about $70bn to support decarbonisation globally. This funding is part of wider financial assistance to help mobilise the estimated $28 trillion that Asia requires. To secure the funding, Japan has already issued part of a $139bn climate transition bond and aims to strengthen the financial support through the Asia Zero Emission Centre, the latest Azec initiative, under which transitional finance will be studied further, a trade and industry ministry official told Argus.

Japan is on track to reduce its GHG emissions by 46pc by the April 2030-March 2031 fiscal year from its 2013-14 level, and hit its net zero emissions goal by 2050.
