Launch Methanation Verification Test in FY2021

Tokyo Gas Co ., Ltd .

Tokyo Gas Co ., Ltd . (President: UCHIDA Takashi; "Tokyo Gas") will begin the verification test (verification test) for methanation, a city gas decarbonization technology, in fiscal year 2021 to realize carbon neutrality and a decarbonized society in 2050 .

Methanation refers to the synthesizing of methane using hydrogen and CO2 . It is positioned as one promising technology for the decarbonization of city gas in the future. By producing city gas from synthesized methane, which in turn is derived from CO2 - free hydrogen and CO2, the existing city gas infrastructure and devices, which include equipment that uses gas, can be used effectively. This will make it possible to curb additional social costs and concurrently achieve the decarbonization of city gas .

The goal of this verification test is to obtain a series of technologies and knowhow spanning from renewable energy -derived power procurement to synthetic methane production and utilization, grasp the actual values and issues for water electrolysis devices and methanation equipment, and learn about the efficiency of the overall system . Regarding methanation, in addition to corroborating Sabatier, an existing technology, Tokyo Gas plans to collaborate with several institutions to develop innovative technologies , including Hybrid Sabatier aiming for further efficiency, a PEM*1 CO2 reduction technology and bioreactor, which are expected to reduce facilities cost. Going forward, Tokyo Gas will examine a local production for local consumption model for regional carbon neutrality, and corroborate developed technologies . This will contribute to the building of a larger -scale verification test and supply chain at Tokyo Gas LNG terminals .

Location: Tokyo Gas site at Tsurumi -ku, Yokohama, Kanagawa (about 2100m 2 )

In the Tokyo Gas Group Management Vision, Compass2030, Tokyo Gas pr omotes the challenge of achieving "Net-Zero CO 2 " and is working to reduce hydrogen production cost and strengthening the development of CO 2 management technology (CCUS 5 ). Through this development project, Tokyo Gas aims for the further early realization of technological development aimed at the decarbonization of gaseous energy. By taking the lead in realizing "Net -Zero CO 2 ". Tokyo Gas plans to contribute to the government 's scheme to "realize a carbon neutral, decarbo nized society in 2050 ."
