The so-called Marlotherm is used as a Liquid Organic Hydrogen Carrier (LOHC), i.e. a liquid carrier medium for hydrogen. This oil-like liquid has been used as a heat transfer oil in a wide variety of applications and industries for years. Its ability to chemically bind hydrogen was discovered some time ago. By chemically binding the hydrogen, it can also be stored under normal conditions, contrary to current practice.
This makes hydrogen handling not only safer, but also cheaper. With LOHC, the volatile hydrogen gas no longer needs to be cooled or compressed in a costly and energy-intensive manner in order to enable economical transport.
One m³ LOHC enables the safe storage of 57 kg H2.
