KBR Selected for Asia’s First Ethanol-to-Jet SAF Plant in Singapore

On June 29, 2026, KBR announced its selection by Keppel Ltd. and Aster Chemicals and Energy to provide technology licensing and Front-End Engineering Design (FEED) services for a proposed 100,000-ton-per-year SAF (SAF) facility on Jurong Island, Singapore.

The planned facility is envisioned as Asia’s first commercial-scale ethanol-to-jet (EtJ) SAF plant. According to the KBR press release, the project will utilize the company’s PureSAF technology to produce a 100% drop-in jet fuel, supporting Singapore’s national mandate to increase sustainability usage across the aviation sector.

PureSAF technology and project scope

The Jurong Island facility will leverage PureSAF, a technology originally developed by Swedish Biofuels AB and engineered for commercial-scale production by KBR, which holds the exclusive global license. The process is designed to convert ethanol into aviation fuel that requires no blending with conventional Jet A or Jet A-1 before use.

In a statement accompanying the announcement, KBR President and CEO Stuart Bradie highlighted the system’s flexibility.

“KBR’s PureSAF is a feedstock-flexible, bankable technology that is designed to deliver a 100% drop in jet fuel, ready to power aircraft without blending. We are constantly innovating our SAF solution to make it compatible with feedstock availability in different regions and to enable the aviation industry to transition to low-carbon jet fuel with a cost-optimized approach.”

The FEED study will determine the technical configuration and project capital expenditure required for the facility. The development remains subject to regulatory approvals and a final investment decision (FID) by the project partners.

Aligning with Singapore’s aviation mandates

The selection of KBR follows a January 28, 2026, agreement between Keppel’s Infrastructure Division and Aster to jointly assess the development of the Jurong Island site. Aster operates as a joint venture between Indonesian petrochemical company Chandra Asri and Swiss commodities trader Glencore.

The proposed 100,000-ton annual production capacity aligns directly with targets set by the Civil Aviation Authority of Singapore (CAAS). Starting in 2026, the CAAS mandates a 1% SAF uplift for all departing flights from the country, with a stated goal of increasing that requirement to between 3% and 5% by 2030.

Alongside the SAF plant contract, KBR and Keppel signed a Memorandum of Intent to collaborate on broader energy transition initiatives. The companies plan to explore technologies related to waste-to-energy, plastic recycling, biofuels, and artificial intelligence-driven digitalization.

AirPro News analysis

We view the progression of the Jurong Island project to the FEED stage as a critical indicator of the Asia-Pacific region’s readiness to scale SAF production. While North America and Europe have led early SAF capacity investments, Singapore’s firm regulatory mandate provides the demand certainty required to underwrite commercial-scale facilities in Southeast Asia. The choice of an ethanol-to-jet pathway is particularly notable, as it allows operators to bypass the constrained supply of fats, oils, and greases that limit hydroprocessed esters and fatty acids (HEFA) production volumes. The project’s ultimate realization hinges on the upcoming final investment decision, which will test the commercial viability of the EtJ process in the current economic environment.
