Karlsruhe, Germany, 30th of October 2025 – Japanese oil and gas company Idemitsu Kosan Co.,Ltd. ("Idemitsu") has invested in INERATEC. INERATEC delivers Power-to-X plants, equipped with proprietary e-Fuel synthesis and upgrading technology.
Idemitsu Kosan is committed to realizing a carbon-neutral society by 2050. The company has recognized the strategic impact of synthetic fuel technologies and has been actively exploring business opportunities. INERATEC operates Europe's largest e-Fuel plant and is at the forefront of modular, efficient synthetic fuel production. The two partners will work together to explore opportunities to accelerate drop-in e-Fuel solutions for aviation, shipping, and other mobility sectors. This paves the way for INERATEC’s entry into the Japanese market, where synthetic fuels are gaining strategic importance as part of Japan’s decarbonization roadmap.
Drop-in e-Fuels produced with modular technology
INERATEC’s proprietary microstructured reactor technology forms the core of its Power-to-Liquid platform. Renewable hydrogen and biogenic CO₂ are converted into synthetic hydrocarbons via the patented Reverse Water-Gas Shift (RWGS) and Fischer-Tropsch (FT) synthesis. The reactor design enables exceptional heat transfer and precise temperature control, significantly enhancing efficiency, yield and load flexibility compared to conventional systems.
INERATEC’s modular plant design translates these advantages into scalable, modular production units that can be installed directly at renewable energy and CO₂ sources. The modular concept reduces time to market, faster ramp-up as well as lower CAPEX and OPEX.
The collaboration combines Idemitsu’s market access and energy expertise with INERATEC’s proven Power-to-Liquid technology (pictured: ERA ONE by INERATEC, Europe’s largest operational e-Fuel plant using via FT). Together, both companies aim to establish cost-efficient, scalable e-Fuel supply chains in Japan and other key markets — accelerating the transition to a carbon-neutral future.
