Innovative Use of Synthetic Methane as City Gas Raw Material Marks a National First
- Toho Gas has launched Japan’s first production of synthetic methane using carbon dioxide and hydrogen, marking a significant advancement towards carbon neutrality.
- The “e-methane” produced will be used as a raw material for city gas, showcasing a sustainable approach to reducing carbon emissions.
Toho Gas has started the production of “e-methane,” a synthetic methane generated from carbon dioxide and hydrogen, in Chita City, Aichi Prefecture. This initiative marks the first time in Japan that synthetic methane is utilized as a raw material for city gas, aligning with the nation’s ambitious goals for achieving carbon neutrality.
The process involves transforming carbon dioxide and hydrogen into methane, a key component of city gas, thereby providing a renewable alternative to conventional natural gas. This innovative approach not only supports Japan’s energy transition but also significantly contributes to the reduction of carbon emissions, with the project expected to cut approximately 60 tons of CO2 annually.
The project harnesses a PEM electrolyser powered by an innovative cold thermal generator that utilizes the cold energy derived from liquefied natural gas. This method efficiently generates hydrogen, which is then combined with carbon dioxide sourced from locally produced biogas.
The integration of these gases occurs through the Sabatier process, a well-established chemical reaction in which hydrogen and carbon dioxide react to form methane and water. This reaction is not only effective in producing methane but also helps in reducing carbon emissions, aligning with global sustainability goals.
This breakthrough by Toho Gas represents a critical step forward in the utilization of sustainable energy sources, demonstrating the potential of synthetic gases to aid in the reduction of greenhouse gases and help cities transition to cleaner energy solutions.
Toho Gas Managing Director Tsuyoshi Haigo: “We believe that e-methane is the mainstay of decarbonizing city gas.We will promote carbon neutrality with as little burden on our customers as possible.”
Toho Gas will continue to manufacture e-methane in the future. Our policy is to increase the scale of equipment and reduce costs.
