Direct synthesis method uses recovered carbon dioxide and hydrogen to produce formic acid

With the goal of achieving a carbon-neutral society and eliminating greenhouse gas emissions by 2050, efforts are accelerating to utilize hydrogen as a key energy source. To achieve this goal, the technologies for hydrogen storage, transportation, and reproduction are actively being developed in Japan, including high-pressure hydrogen, liquid hydrogen, and liquid organic hydrogen carriers (LOHCs) such as methylcyclohexane.
