“Green hydrogen” manufactured in Australia,
Demonstration experiment to liquefy and import to Japan
Announced that it was carried out.
In the future, we aim to increase the size of manufacturing equipment and commercialize it after 2030.

Liquidation of green hydrogen:

Using solar power,
Electrolyze water and toluene,
It was made into a liquid called methylcyclohexane (MCH).
Transporting MCH of liquefied hydrogen:

After that, MCH of liquefied hydrogen was imported to Japan.

In Japan, we succeeded in extracting hydrogen from MCH and running FCV.

Transporting MCH at room temperature:

To carry hydrogen as it is, it is necessary to cool it to 253 degrees Celsius, liquefy it, and use a special ship. Twice

On the other hand, MCH can be transported at room temperature.

Oil tankers and storage tanks can be used as they are, reducing transportation costs.

Extract hydrogen from MCH:

In 2019, the two companies conducted a demonstration experiment to extract 0.2 kilograms of hydrogen from MCH.

In this experiment, we increased it to 6 kilograms.

It is said that the tank of Toyota’s FCV “Mirai” can be filled up.

It is said to be the world’s first practical-level transportation.

This time, by adopting a new technology that can directly reduce toluene to MCH, the equipment cost has been halved.

In the future, we will promote the enlargement of the electrolytic cell and reduce the cost for commercialization.

ENEOS, Chiyoda, and QUT Successfully Scaled Up an Australian CO2-Free Hydrogen Supply Chain Demonstration using Direct MCH®

~Filling a FCV with hydrogen derived from renewable energy~

ENEOS Corporation
Chiyoda Corporation
Queensland University of Technology (President: Margaret Sheil; “QUT”)

announced that they had succeeded in expanding the scale of their technological verifications of CO2- free hydrogen to a practical level for the first time in the world.

We commenced technical verifications of the production, transportation, and dehydrogenation of CO2-free hydrogen in 2018.

In order to store and transport hydrogen, it was previously necessary to store hydrogen produced via water electrolysis in a tank,

then convert it to methylcyclohexane (“MCH”), which is a type of organic hydride.

The technology developed by ENEOS
significantly simplifies this process,

by directly producing MCH from water and toluene through the electrochemical synthesis of organic hydride*2(Direct MCH® *3).

In March 2019,
ENEOS, Chiyoda and QUT

succeeded in directly producing MCH from water and toluene derived from Australian renewable energy,

transporting this MCH to Japan, and extracting hydrogen from it.

This was the first successful verification of such a technology in the world,

but produced only a lab- sized amount of MCH containing 0.2 kilograms of hydrogen.

We have expanded the scale of MCH produced to a practical level so that it contains approximately 6 kilograms of hydrogen;

they have also extracted hydrogen from this MCH in Japan, and actually used the hydrogen to fill and drive a fuel cell electric vehicle (FCEV).

For the reasons listed below, the technologies of ours used in this technological verification are superior to other technologies for a transportable hydrogen supply chain.

Party Technology Features
November 2, 2021

QUT Concentrated Photovoltaic Power Generation System

A power generation system that captures sunlight by gathering solar irradiation with a Fresnel lens and adjusting the orientation of solar panels according to the position of the sun; compared to fixed-array solar panels, the system generates a much higher amount of electricity per unit surface area.

ENEOS Direct MCH®

A high-efficiency electrolysis process that converts toluene directly into MCH, without first converting it into hydrogen;

it is capable of reducing facility costs for MCH production by approximately 50%*4 compared to the conventional process to produce MCH.

Chiyoda Dehydrogenation technologies

Using independently developed catalysts and dehydrogenation reactors, the technologies generate extremely high hydrogen yields from MCH.

In anticipation of a hydrogen-oriented society, ENEOS intends to further increase production volumes
