IHI and IHI ASIA PACIFIC PTE. LTD. (“IHI”), in collaboration with the A*STAR Institute of Sustainability for Chemicals, Energy and Environment (“A*STAR ISCE²”) ^(*1) in Singapore, held an opening ceremony on January 15, 2025 to mark the completion of a Sustainable Aviation Fuel (SAF) ^(*2) production test rig for CO₂ direct-conversion to liquid hydrocarbons, with a capacity of 5 kg per day. The technology streamlines the process by enabling a single step carbon dioxide direct-conversion to liquid hydrocarbons. This approach simplifies the production process, thus enhancing energy efficiency and reducing operational complexity.

The event was attended by over 100 guests, including government officials from various countries and the companies and organizations involved in the SAF value chain. IHI showcased the SAF production technology currently under development and its future ambition toward commercialization.

The International Civil Aviation Organization (ICAO) has set a long-term goal of net zero aircraft CO₂ emissions by 2050, and it is envisaged that many conventional fossil-based aviation fuels will be replaced by SAF. In response this need, IHI is developing catalysts and building efficient processes to produce SAF directly from CO₂ and hydrogen.

IHI and A*STAR ISCE² have previously developed a novel catalyst for SAF production in 2022, which was confirmed to have world-class performance in laboratory tests. The performance and durability of this catalyst will now be evaluated in the newly installed test rig. Both parties will further optimize the operating conditions of the test rig and acquire reactor data to verify the entire production process.

IHI aims to accelerate the SAF deployment through cooperation with various partners, eyeing ASTM approval^(*3) in the latter half of the 2020s and commercialization of the technology around 2030.

(*1) A*STAR Institute of Sustainability for Chemicals, Energy and Environment (A*STAR ISCE²)
A*STAR has established a research institute to support Singapore’s sustainability goals. Known as the Institute of Sustainability for Chemicals, Energy and Environment (ISCE²), the institute advances R&D in areas such as low-carbon technologies, carbon life cycle assessment, sustainable materials and green manufacturing processes using the latest digitalization and automation tools. See https://www.a-star.edu.sg/isce2/about-us for detail.

(*2)SAF（Sustainable Aviation Fuel）
Aviation fuel produced from non-conventional, sustainable feedstocks. Efforts to promote the use of SAF across the world are gaining momentum since SAF could decrease its lifecycle emission ranging from fuel production to combustion compared to conventional fossil fuels without changing existing aviation infrastructures.

(*3)ASTM Approval
For commercial deployment of SAF, the fuel must meet the standard ASTM D7566, the specification for synthetic aviation turbine fuels, regulated by ASTM International.
