Study for commercial-scale hydrogen imports
Port of Rotterdam Authority, Koole Terminals, Chiyoda Corporation, and Mitsubishi Corporation have signed an agreement to jointly study the feasibility of a commercial-scale import of hydrogen from overseas sources to one of Koole’s terminals in the port of Rotterdam utilizing Chiyoda’s proven hydrogen storage and transportation technology SPERAHydrogen™.
Northwest-Europe will have to import hydrogen on a large scale to become net-zero CO2 emission. The Port of Rotterdam Authority is therefore looking at ways to set up new hydrogen supply chains from countries where hydrogen can be produced and supplied cost-effectively. Several companies in Rotterdam, such as Koole Terminals, are highly interested in this rapidly developing new business and are making plans to innovate their existing facilities and/or build new ones. The Port of Rotterdam Authority is supporting such activities.
Shipping hydrogen is more challenging than shipping oil or coal. One option is for it to be made liquid by a cryogenic process to minus 253 degrees, another is to transform it into a carrier, like ammonia or methanol or lastly, it could be chemically combined in a so-called liquid organic hydrogen carrier (LOHC) (*1). Methylcyclohexane (MCH) (*2) is a LOHC.
It maintains a stable liquid state under ambient temperature and pressure. As a means of storage and transportation of hydrogen, MCH is comparable with petroleum and petrochemical production in terms of the risks involved. Chiyoda Corporation has developed the SPERA Hydrogen technology to release hydrogen from MCH. MCH is produced from toluene through the hydrogenation process. When hydrogen is generated from MCH, toluene is produced simultaneously, which can be shipped back to be used as a material of MCH again.
n 2020 Chiyoda Corporation, Mitsubishi Corporation and MITSUI & CO., LTD. and Nippon Yusen Kabushiki Kaisha successfully completed the demonstration project of the long-distance transportation (5000km) and storage of hydrogen using Chiyoda Corporation’s SPERA Hydrogen technology by producing MCH in Brunei, shipping it to Japan and shipping toluene back to Brunei.
This was the world’s very first global hydrogen supply chain project proving the technical readiness for commercial use. SPERA Hydrogen is expected to play an important role in the realization of commercial-scale hydrogen supply chains globally and contribute to global carbon neutrality in 2050. One of the major advantages of MCH over liquid hydrogen and ammonia as a hydrogen carrier is that it makes use of existing infrastructure and vessels, and is easier to handle.
