CO2 Emission and Reduction Target for Japan

Material from “Long-term perspective on CO2 reduction by utilizing CCS technologies” presentation by MOEJ @ GHGT-14


Japanese Government Policy Settings on CCUS (1)

Research and development will be conducted with a view to practical use of the carbon capture, utilization andstorage (CCUS) technology around 2020 and, with due consideration given to the possible timing of the commercializationof carbon capture and storage (CCS) technology, a study will be conducted on introducing CCS-ready facilities as early aspossible. Through these measures, including steady efforts toward the demonstration of a series of CCS processes ofcapture, transportation, injection and storage in Japan and a study on suitable sites for storage, the introduction ofcoal thermal power generation that gives consideration to further reduction of the environmental impact will be promoted.

Cabinet Decision on July 2018Strategic Energy Plan

2050 scenario for significant reduction in various sectors in 2050:• Share of low carbon electricity supply (i.e., renewable energy, CCS and nuclear) increases to more than 90%• CCS and CCU is deployed to most of the fossil fuel fired power plants and to parts of other industrial

emission sources

Ministry of the Environment (MOEJ)’s Long-Term Low Carbon Vision Central Environment Council, March 2016



Japanese Government Policy Settings on CCUS (2)

To urge the power sector to develop an effective sector-wide framework for CO2 emissions reductionMETI&MOEJ, April 2013

Ministry of Economy, Trade & Industry (METI) & MOEJ Agreement on Fossil Fuel Fired Power Plants

In relation to the 2050 goal of GHG emission reduction:• To accelerate technology development of CCS and conduct a survey on potential CO2 storage sites for

commercialization of CCS by around 2020• To consider introduction of CCS at coal-fired power plants by 2030 and identify requirements for CCS Ready• For power plants expected to operate up to 2050, we urge operators to consider technology development for

practical use of CO2 capture facilities

1. Sustainable CCS Project - Demonstration of large-scale CO2 capture technology (1)

The CO2 Capture Demonstration Plant will be designed and built to capture more than 500 tons-CO2/day from Mikawa Power Plant (more than 50% of its total emissions)

The Capture Plant will be built and fully integrated with the Power Plant, with turbine extraction steam feeding the energy for regeneration of CO2 at the stripper tower.

The old coal boiler was replaced with a boiler capable of also burning 100% biomass. The new boiler is now fully operational and normally operating on biomass fuel. Consequently, the project will become one of the first BECCS project in the world.

1. Sustainable CCS Project - Study for captured CO2 transportation by ship

Why offshore CO2 storage ?1. Most of CO2 emission sources exist along coasts.2. Offshore areas are less used compared to coastal waters.

Key benefits of CO2 transportation by Ship1. Easy to match source and sink2. Flexible to change transportation/storage plans



1. Sustainable CCS Project -


Study for constraining and remediatingCO2 leakage stored under seabed

Establish geological modeland evaluation method

Study for constraining and remediating CO2 leakage

Create monitoring planbelow the seafloor


2. Investigation of Potential CO2 Storage Sites

Note) Mizuho Information & Research Institute creates these figures by using data of RITE “Nationwide storage potential quantity survey”, and NEDO/AIST (2012) “Evaluation of integrated system covering from power generation to carbon dioxide storage” etc.

Identify potential CO2 storage sites in waters surrounding Japan by 2021. A previous study conducted by RITE in 2005 estimated that there is about 146 billion tons of

CO2 storage potential in the offshore waters of Japan.
