Baere Aerospace Completes Report Assessing ASTM Testing Methods for Alternative Jet Fuels

05 January 2018 – Baere Aerospace Consulting, Inc. has provided CAAFI with a white paper on “Considerations for Using Existing Standards as Part of Alternative Jet Fuels Approval and Deployment”, summarizing their report performed for the Coordinating Research Council (CRC) under the document AV-23-15 “Adequacy of Existing Test Methods for Aviation Jet Fuel and Additive Property Evaluation,” July 2017, available from The work entailed reviewing all of the standards and specifications referenced in ASTM D-1655 Standard Specification for Aviation Turbine Fuels, ASTM D7566, Standard Specification for Aviation Turbine Fuels Containing Synthesized Hydrocarbons, and ASTM D4054, Standard Practice for Qualification and Approval of New Aviation Turbine Fuels and Fuel Additives to determine what, if any, impact a change in the fuel composition or in how the standard was used might have on the results. The purpose of the study was to assess the continued adequacy of the referenced test standards for use with: fuels prepared in manners other than those used with traditional petroleum crude; D7566 blendstocks which may not be fluids meeting the traditional kerosene distillation profile; and additives. Out of 140 test methods identified, six documents of probable concern are presented in the white paper.

CAAFI works closely with ASTM, CRC, and other entities to enhance the certification process for alternative jet fuels.

CAAFI’s SOAP-Jet Series Continues with ASCENT Projects Overview

15 December 2017 – On December 8, 2017, CAAFI’s R&D Team continued the SOAP-Jet webinar series with a presentation on current alternative jet fuel-related work under the Aviation Sustainability Center (ASCENT), presented by ASCENT’s Director, Dr. Michael Wolcott (Washington State University). Funded by FAA, ASCENT consists of researchers from 16 universities studying a broad range of topics related to alternative jet fuels and the environment, such as the commercial development of sustainable alternative jet fuel production pathways and measures for improving the health and life quality of those working and living around airports.

Dr. Wolcott presented an overview of ASCENT and highlighted two ASCENT projects. First, he spoke about the Alternative Jet Fuel Supply Chain Analysis project, which seeks to identify key barriers to the production of 1 billion gallons of alternative jet fuel in the near term and 10 billion gallons in the longer term. The project team is evaluating the technoeconomics of fuel production pathways, potential feedstock availability, infrastructure requirements, commercial fuel demand, and novel co-products in an effort to construct supply-chain scenarios for future sustainable alternative jet fuel production at both national and regional scales. The team is also working to facilitate specific regional approaches to supply chain development. Dr. Wolcott also discussed the National Jet Fuel Combustion Program, which is developing combustion-related generic test and modeling capabilities to better understand the impacts of a fuel’s chemical composition and physical properties on combustion and emissions, with the goal of accelerating the certification process of new alternative jet fuels.

The webinar was well-attended with approximately 70 participants. To view the presentation slide deck, click here.

SOAP-Jet webinars are intended to provide a forum for members of the alternative jet fuel community to discuss progress and related gaps and challenges, share lessons learned, methodologies, and strategies in order to promote communication among stakeholders and enable commercialization of Sustainable Alternative Jet Fuel (SAJF).

Hainan Airlines Conducts First Chinese Trans-oceanic Flight Powered on Biofuels

23 November 2017 – Hainan Airlines conducted China’s first transoceanic flight powered by biofuels on 21 November. The Boeing 787 flight carried 186 passengers and 15 crew members from Beijing to Chicago's O'Hare International Airport, covering a distance of 11,297 kilometers over 11 hours and 41 minutes. An alternative jet fuel (AJF) blend comprised of 15% hydroprocessed waste cooking oil and 85% conventional aviation fuel powered the flight.

The AJF blend was supplied to Hainan Airlines by China Petroleum and Chemical Corp. The blend’s renewable fuel component was sourced from restaurant waste cooking oil and produced at Zhenhai Refining and Chemical Co, a subsidiary of Sinopec based in Ningbo, Zhejiang province. Xu Chaoqun, head of the airworthiness certification department at the Civil Aviation Administration of China (CAAC), said biofuels use is an important development in the global aviation fuel market. "It's critical to develop green alternative energy, and push forward the R&D and application of biofuel with independent intellectual property rights. The biofuel developed by Sinopec is the first such aviation fuel that has been approved by the CAAC.", Chaogun said. Sinopec spokesman Lyu Dapeng said the AJF had met stringent safety standards, and Sinopec will speed up its commercial application with the support of supply chain partners.

Qantas Airways Partners with Feedstock Supply Company Agrisoma to Establish AJF Supply Chain in Australia

21 November 2017 – Agrisoma and Qantas Airways have partnered to establish a commercial alternative jet fuel supply chain in Australia. Agrisoma, a Canadian company, will supply Brassica carinata seed, a feedstock suitable for jet fuel, to Australian farmers. Agrisoma aims to eventually grow the crop on nearly 1 million acres in Australia, producing more than 50 million gallons to replace up to 50 percent of the airline’s annual fuel needs. A demonstration flight using alternative jet fuel derived from Brassica carinata seed between the United States and Australia is scheduled for January 2018. There are still a lot of questions, such as who will convert the feedstock into jet fuel, but for now the focus by an end user on crop development is a novel approach. The Australian supply chain is expected to produce fuel for the airline before the end of 2019. Read more about the agreement here.

Gevo supplies SAJF (ATJ-SPK) to 8 airlines at ORD, demonstrating use of standard infrastructure for fuel delivery

8 November 2017 – Today, is “Fly Green Day” at Chicago’s O’Hare International Airport (ORD). What does that mean? Eight commercial airlines (Lufthansa, United, Etihad, Cathay Pacific, Emirates, Japan Airlines, Korean Air, and Atlas) will fly out of ORD today using Gevo’s alcohol-to-jet fuel (ATJ) derived from renewable isobutanol. Gevo structured this activity to validate the capability to deliver SAJF to the aircraft’s wing using the airport’s main fuel system infrastructure (terminals, pipelines, storage tanks and hydrant system), enabling minimized delivery costs and effort. Up to this point, most SAJF demonstrations have had fuel delivered by truck to the aircraft or airport fuel farm. Gevo also recently announced they will be executing similar activities at Brisbane airport in Queensland, Australia in conjunction with Virgin Australia.

The isobutanol-based ATJ-SPK process has been included in the ASTM D7566 specification for synthetic turbine fuels (Annex A5) since 2016.
