Toward the realization of JERA Zero CO2 Emissions 2050JERA Zero CO2 Emissions 2050 challenges us to achieve effec-tively zero CO2 emissions from our domestic and international businesses by 2050, and we have adopted a three-pronged approach toward achieving this goal.1 Complementarity between renewable energy and zero CO2 emission thermal power generationJERA will achieve Zero CO2 emissions through a combination of renew-able energy and zero CO2 emission thermal power generation. The adoption of renewable energy is supported by thermal power generation capable of generating electricity regardless of natural conditions. JERA will promote the adoption of greener fuels and pursue thermal power that does not emit CO2 during power generation.2 Establishment of roadmaps suitable for each country and regionZero CO2 emissions will be achieved by establishing roadmaps that show optimal solutions for each country and region. Since the energy situation is different for each country and region-such as the presence of regional transmission lines or pipelines and the types of renewable energy that could be adopted-JERA will work with stakeholders on a country and regional basis to establish roadmaps. We have developed a roadmap for our business in Japan and will extend this approach to other countries and regions.3 Smart transitionZero CO2 emissions will be achieved through a combination of technolo-gies that are available and reliable at the time adoption decisions are made, lowering technical risk and smoothing the transition to a green society.* “JERA Zero CO2 Emissions 2050” is premised on steady advances in decarbonization technology, economic rationality, and consistency with government policy. JERA is developing its own decarbonization technologies and taking the initiative to ensure economic rationality.3JERA is actively working to reduce CO2 emissions. In its domestic operations, JERA will achieve the following by FY2030:• Shut down all inefcient (supercritical or less) coal power plants and conduct demonstration tests of mixed combus-tion with ammonia at high-efciency (ultra-supercritical) coal power plants.• Promote the development of renewable energy centered on offshore wind power projects and work to further improve the efciency of LNG thermal power generation.• Reduce carbon emission intensity of thermal power plants by 20% based on the long-term energy supply-demand outlook for FY 2030 as set by the government.TOPICSStart of the ammonia co-ring demonstration projectThe New Energy and Industrial Technology Development Organization (NEDO) decided to subsidize JERA's demonstration project with the goal of assessing the heat absorption characteristics of boilers and the environmental load characteristics of exhaust gases and other emissions for the establishment of carbon-ammonia co-ring technology. The plan is to co-re Unit 4 (power generation output: 1 GW) at Hekinan Thermal Power Station in FY2024 using 20% ammonia. It will be the rst demonstration project in the world co-ring such a large amount of ammonia in a large-scale commercial coal-red power plant.

JERA will revise the roadmap when relevant conditions change significantly. * The use of CO2-free LNG is also being considered.Launch full-scaleoperationLaunch full-scale operationIncreasethe co-firing rateIncreasethe co-firing rateFinalize details in light of results of demonstrationDemonstrationVerify safe operations at actual power stationsResolve technical issues (selection of hydrogen)reduction of CO2 emissionsintensity Zero CO2emissions20%Zero CO2 emissions thermalpower generationShut downinefficient coalpower plantsCo-firing withammoniaCo-firing withhydrogen*Achieve a 20% reduction of carbon emission intensity from all thermal power generation in Japan based on the Japanese government’s Long-Term Energy Supply and Demand Outlook for fiscal 2030Conduct proving tests at an actual coal power plants (Proposed: Hekinan Thermal Power plants)Select the technically and economically optimal hydrogen carrier from among ammonia, liquefied hydrogen, methylcyclohexane (MCH), etc.Begin transition to use of 100% ammonia, without mixing with other fuels, in thermal power generation Shift to thermal power plants using 100% ammonia as fuel as power stations are replaced48Chubu Electric Power Group Report 2021Top CommitmentValue CreationClimate ChangeStrategyBusiness ActivitiesGovernanceHuman ResourcesFinancial / Corporate Data
