Tokyo, August 21, 2024 –Tokyo Gas Co., Ltd. (Tokyo Gas), Osaka Gas Australia Pty Ltd (OGA),
Toho Gas Co., Ltd and Santos Ltd (Santos) through Santos Ventures Pty Ltd, a subsidiary ofSantos, have entered into an agreement to conduct a pre-FEED study on a project to produce emethane*１ at Moomba in the Cooper Basin, located in the central eastern part of Australia, whereSantos has knowledge from decades of development and operation of upstream gas fields, and toexport e-methane to Japan.
This study is based on the results of the feasibility study*2 undertaken by Tokyo Gas and Santossince November 2023. The project aims to export more than 130,000 tons of e-methane per year
(equivalent to approx. 180 million m3 of city gas per year) to Japan from 2030 at the earliest.
For this Pre-FEED initiative, Tokyo Gas has secured a subsidy of Japan’s Ministry of Economy,
Trade, and Industry*3.
Tokyo Gas is collaborating with various entities in Japan and overseas to achieve net-zero CO2emissions, a goal set forth in the Group Management Vision "Compass 2030", by combining
renewable energy, hydrogen, methanation*4, CCUS, and other measures. In particular, we areworking toward the future implementation of e-methane, aiming to introduce e-methane
equivalent to 1%＊5 of Tokyo Gas' gas sales volume by 2030, and more than 10 times carbon
neutral gas by 2040. Tokyo Gas has been promoting e-methane demonstration projects in Japanand strive to establish a large-scale global e-methane supply chain that includes North America,
Southeast Asia, the Middle East and Australia. Tokyo Gas will continue to strive for the early
establishment of the e-methane supply chain and contribute to the Japanese government’s goal ofcarbon neutrality in 2050.
