Feasibility Study on Establishing a Lower-Emissions Fuel Ammonia Supply Chain
from Australia to Japan (Phase 2)

Woodside Energy Ltd. (“Woodside”), Japan Oil, Gas and Metals National Corporation(“JOGMEC”), Marubeni Corporation (“Marubeni”), Hokuriku Electric Power Company(“Hokuriku Electric”), The Kansai Electric Power Co., Inc. (“Kansai Electric”), Tohoku ElectricPower Co., Inc. (“Tohoku Electric”), and Hokkaido Electric Power Co., Inc. (“HokkaidoElectric”) have signed a joint research agreement under which they will jointly conduct a
feasibility study (Phase 2) on the establishment of a lower-emissions fuel ammonia supply
chain from Australia to Japan (the “Project”).
Ammonia does not emit carbon dioxide (CO2) during combustion and is considered apromising next-generation lower-emission fuel for energy intensive thermal power plants andmarine engines. Given existing proven technologies for the production, storage, andtransportation of ammonia, it is expected to have early take-up as a lower-emission fuel.
In addition, the Sixth Strategic Energy Plan, published on October 22, 2021, states thatammonia-fueled power generation is one of the most promising options for decarbonizing
power sources toward achieving carbon neutrality by 2050 since it does not emit CO 2 during
combustion and can be utilized in many existing power generation facilities such as boilers
and denitration facilities without modification.
Last year, Woodside, JOGMEC, Marubeni, Hokuriku Electric, and Kansai Electric
conducted a feasibility study on the entire supply chain, including the production of loweremissions ammonia in Australia from natural gas with CO2 abatement methods such as
Carbon Capture and Storage (CCS), Carbon Capture and Utilisation (CCU) 1 , and biosequestration; marine transportation to Japan; ammonia’s utilization as a fuel for power
generation and marine use; and financing. In last year’s study, the parties sought to address
the feasibility of establishing a supply chain in relation to economics and CO2 emission
reduction.
As part of Phase 2 of the Project, seven parties, including Tohoku Electric and Hokkaido
Electric as new participants, will conduct a further detailed feasibility study to inform the1

Technology to capture and store (CCS: Carbon dioxide Capture and Storage) or effectively utilize(CCU: Carbon dioxide Capture and Utilization) CO2 emitted from factories and power plants.

viability of establishing a lower-emissions fuel ammonia supply chain based on the results ofthe feasibility study conducted the previous year.
All parties participating in this project will continue the research already conducted in orderto establish a lower-emissions fuel ammonia supply chain between Australia and Japanthrough collaboration, in an effort to assist the decarbonization of Australia and Japan.
