Japanese energy company Eneos has partnered with Honeywell to begin basic engineering for what is set to be the first commercial-scale hydrogen supply chain in Japan based on MCH (methylcyclohexane). The project aims to facilitate hydrogen transport using Honeywell UOP’s dehydrogenation process, supporting production, storage, distribution, and material recycling within Eneos refineries.

Eneos, one of Japan’s leading energy companies, has started basic engineering in partnership with Honeywell to establish the first commercial-scale hydrogen supply chain based on Honeywell UOP’s methylcyclohexane (MCH) dehydrogenation process.

The project includes production, storage, transportation, distribution and material recovery to recycle components involved in the hydrogen process.

Eneos is planning to install the MCH unit within its refineries in Japan. The Honeywell UOP MCH dehydrogenation process enables safe and effective long-distance transport of hydrogen, playing an important role in the Honeywell Liquid Organic Hydrogen Carrier (LOHC) Solution.

“With global energy demand on the rise, regions are seeking to incorporate additional energy sources, including cost-effective hydrogen imports. Nations possessing abundant renewable energy resources or established hydrogen infrastructure are particularly well-suited to become key suppliers,” said Rajesh Gattupalli, president of Honeywell UOP. “Our MCH dehydrogenation process will assist Eneos in enhancing the commercial viability of hydrogen to meet the increasing energy requirements.”

Hydrogen gas is converted into MCH through Honeywell’s Toluene Hydrogenation process. In this state, the MCH is then transported via ship or tanker. Once at its destination, hydrogen gas is extracted from MCH through Honeywell's MCH dehydrogenation process. The remaining byproduct, toluene, can be returned and recycled for future use.

Honeywell and Eneos are actively collaborating on hydrogen transportation projects. In 2024, Honeywell announced plans to develop the world’s first commercial-scale LOHC project at various Eneos sites.
