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.
One example is the transportation of hydrogen produced from lignite coal overseas to Japan, where it is used as liquid hydrogen in fuel cell vehicles, trains, forklifts, etc. Demonstration tests for these applications are already underway.
On the other hand, the use of high-pressure and liquid hydrogen, for example, presents challenges. It requires specialized equipment and heavy containers for safe storage and transportation, which pose safety risks and increased costs, limiting widespread adoption.
