Idemitsu Kosan Co.,Ltd. (Head Office: Chiyoda-ku, Tokyo; Representative Director and President: Noriaki Sakai; hereinafter "the Company") has invested in ATOM-X (Headquarters: USA; Co-founder/CEO: Davide Menga; hereinafter "ATOM-X"), a company that directly synthesizes e-methanol (※2) from water and CO2 at room temperature and pressure, through Idemitsu CVC (※1), and has commenced a joint study for business collaboration in the e-methanol field.
ATOM-X is an MIT-spawned startup that possesses technology to produce e-methanol by direct electrolytic synthesis from water and CO2 under normal temperature and pressure conditions. Through this joint study, the Company aims to implement this technology and achieve cost-competitive supply of e-methanol.
※1 Idemitsu CVC (Idemitsu Corporate Venture Capital): An organization that makes strategic investments in "innovative new technologies" in the "low-carbon energy" and "advanced materials" fields to contribute to the realization of a carbon-neutral and circular society.
※2 e-methanol: A type of synthetic fuel obtained by synthesizing green hydrogen, produced by electrolyzing water using electricity from renewable energy, with CO2 recovered from the atmosphere or other sources.
Electrolysis equipment under development by ATOM-X
E-methanol is expected to be a next-generation energy source that can contribute to the decarbonization of many sectors, as it can be used not only as marine fuel but also to produce jet fuel, gasoline, and chemical raw materials. The Company positions e-methanol, with these features and versatility, as a strategically important product and is working on its societal implementation.
Currently, the mainstream method for producing e-methanol involves producing hydrogen through water electrolysis and then synthesizing it with CO2. These processes also require reactions under high temperature and high pressure. ATOM-X, in which the Company has invested, possesses technology for direct electrolytic synthesis of e-methanol from water and CO2 under mild conditions of normal temperature and pressure, using its unique catalyst. Compared to conventional e-methanol production processes, this simpler and less environmentally burdensome process is expected to reduce equipment costs, manufacturing energy, and overall costs.
This technology is currently in the research and development phase, with verification, evaluation, and improvements underway for future scale-up and practical application. The Company will accelerate its efforts toward the societal implementation of e-methanol by conducting joint studies with ATOM-X, which possesses technology that can significantly contribute to improving the cost competitiveness and practicality of e-methanol production, regarding the possibilities of business collaboration.
Comparison of e-methanol production methods and processes
The Company will continue to strengthen cooperation with various startup companies in the future, incorporating innovative technologies and ideas, and working to create new value and solve social issues.
