Japan’s ENEOS Synthetic Fuel Project Shows Potential Alternative to Petrol and Diesel

ENEOS Corporation, Japan’s largest oil refiner, has successfully demonstrated the production of a new synthetic fuel created using carbon dioxide captured from the atmosphere and hydrogen extracted from water.

The breakthrough project has drawn international attention because the fuel could eventually become an alternative to conventional petrol and diesel. If commercial production becomes viable in the future, experts believe it may help reduce dependence on expensive imported fuel in countries such as Pakistan, India, Bangladesh, and Sri Lanka.

According to official project disclosures and industry reports, ENEOS developed a synthetic fuel demonstration plant at its Central Technical Research Laboratory in Yokohama. The facility can currently produce around one barrel, or nearly 160 litres, of synthetic fuel per day.

How ENEOS Produced the Synthetic Fuel

The ENEOS project combines multiple advanced technologies to create liquid fuel without relying on crude oil extraction.

First, the company uses Direct Air Capture technology to collect carbon dioxide directly from the atmosphere. The captured CO₂ then becomes one of the key ingredients for fuel production.

At the same time, hydrogen is extracted from water through an electricity based process. Renewable energy sources are generally used to power this stage to reduce carbon emissions.

Afterward, the collected carbon dioxide and hydrogen are converted into liquid hydrocarbons through synthetic fuel methods such as Fischer Tropsch synthesis. The final product closely resembles traditional petroleum fuels.

Industry experts describe the product as a “drop in” synthetic fuel because it can operate in existing internal combustion engines and fuel infrastructure without requiring major modifications.

Real World Testing Already Conducted

The company has already tested the fuel beyond laboratory conditions. Fuel produced at the Yokohama demonstration plant powered a shuttle bus during Expo 2025 Osaka, proving that the technology can function in real transportation systems.

The successful transportation trial strengthened confidence in the technical viability of synthetic fuel technology. It also demonstrated that vehicles currently running on petrol or diesel could potentially use the fuel without engine redesign.

ENEOS confirmed that it started Direct Air Capture demonstration testing in 2023 to evaluate future scalability and commercial deployment opportunities.

Commercial Challenges Remain

Although the project successfully demonstrated that fuel can be produced from air and water, large scale commercialization has not yet started.

Recent industry reports indicate that ENEOS paused further expansion after the demonstration phase due to high production costs and scalability concerns. Analysts say the main obstacle remains the enormous electricity demand required for hydrogen production and fuel synthesis.

Synthetic fuels currently remain more expensive than conventional petroleum products in most markets. As a result, experts believe wider commercial adoption may depend on cheaper renewable electricity and stronger government support for low carbon energy technologies.

Despite these economic hurdles, the project did not fail technically. Researchers continue to view synthetic fuels as an important long term solution for reducing emissions in sectors where electric alternatives remain difficult.

Global Interest in Synthetic Fuels Growing

Countries and energy companies around the world are increasingly investing in synthetic fuel research as governments push toward carbon neutrality goals.

Synthetic fuels produced using captured CO₂ and renewable hydrogen are especially being explored for industries where electrification remains challenging. These sectors include aviation, shipping, heavy transportation, and industrial energy use.

Japan continues to support carbon neutral fuel innovation as part of its broader decarbonization strategy. ENEOS also remains involved in ongoing research into cleaner energy solutions and low emission fuels.

Energy analysts say future breakthroughs in renewable power generation and carbon capture technology could eventually reduce costs and make synthetic fuels more commercially attractive worldwide.
