Japan’s Eneos exploring hydrogen business in Australia

Japanese oil refiner Eneos and Australia-based French renewable energy firm Neoen will study the development of a supply chain for stable, affordable green hydrogen in anticipation of a significant rise in hydrogen demand in Japan.

The companies will explore producing green hydrogen in South Australia, where they can reduce production costs by utilising large areas of land and good weather conditions. Green hydrogen is produced using renewable energy sources through the process of electrolysis by splitting water into hydrogen and oxygen. The green hydrogen will be shipped to Japan using Eneos-owned tankers after it is converted into methylcyclohexane (MCH) at Neoen's Australian plant, for which details are unclear. But Neoen is studying the technical and economic feasibility of a hydrogen production facility at its Crystal Brook Energy Park project in South Australia, which combines solar and wind generation and battery storage, according to the South Australian government's renewables website.

Eneos is planning to use existing infrastructure such as tanks and dehydrogenation units at its refineries to deliver the imported hydrogen to nearby industries, including thermal power plants and steel mills. Toluene, which is separated from hydrogen in the dehydrogenation process at Eneos' refineries, will be sent back to Australia to be used as a raw material in MCH production.

The companies are considering ways to ensure stable renewable electricity supplies, such as combining wind, solar and battery storage to counter the effect of unfavourable weather. Neoen has more than 2GW of renewable energy generation capacity, according to Eneos.

Eneos is speeding up the development of CO2-free hydrogen supply chains to achieve carbon neutrality by 2040. The company is separately studying another hydrogen project. The project will start with investigating supply of CO2-free hydrogen through existing pipelines owned by various energy sectors at Kawasaki in the Tokyo bay area, Eneos said.

These projects may be connected in the future, as the Kawasaki project is supposed to import MCH produced in an overseas plant.
