Two New Alternative Jet Fuel Production Pathways Approved

May 19, 2020 - CAAFI is happy to announce the latest industry alternative jet fuel (AJF) Production Pathway approvals, and ASTM publication of:

1) A new ASTM D7566 alternative jet fuel production pathway: ASTM D7566 Annex A7 – Hydroprocessed Hydrocarbons (HH-SPK, or HC-HEFA).
This addition describes the hydroprocessing of bio-derived hydrocarbons (as opposed to simply fatty acids or fatty acid esters entailed in HEFA production), for instance those obtained directly from oils (triterpenes) produced by the Botryococcus braunii algae. This task force and research activity was led by IHI Corporation using both the FAA Clearinghouse concept as well as the industry’s D4054 Fast Track provision. The Clearinghouse is intended to streamline the management of the testing and data review of SAF candidates. The University of Dayton Research Institute (URDI) is the project leader for Clearinghouse activity, and is initially funded under ASCENT to support Phase 1 testing and research review. IHI’s timely completion of approval indicates both concepts are impactful, and enable the qualification process for select new pathways to be completed at reduced cost and timeframe. In line with Fast Track provisions, the HH-SPK will initially have a 10% max blending level.

2) The addition of a new type of renewable content for refinery coprocessing of fuels from non-conventional sources: ASTM D1655 Annex A1 addition of Fischer Tropsch biocrude.

The second change is the inclusion of Fischer-Tropsch (FT) biocrude as an allowable feedstock for petroleum co-processing. It’s task force and research activity was led by Fulcrum. As with the earlier approval of lipid co-processing, this co-processing will be limited to a 5% by volume limitation on both feedstock volume and synthesized final product content.

Steve Csonka, CAAFI Executive Director adds that “The industry remains active in improving the fuel qualification process, in participating in new pathway evaluations, and in engaging prospective technology developers and commercialization entities with interest in SAF. All of these activities are important to the long term goals of the industry including introducing additional conversion processes that will enable SAF production from any viable feedstock, worldwide, and continue to offer cost reductions in both plant and equipment as well as operating cost

Queensland Grants Funding to Two Sustainable Aviation Fuel Projects

March 11, 2020 – The Queensland Waste to Biofutures Fund is an initiative to grow and enhance the bioeconomy in Queensland by increasing the capacity to produce bioenergy, biofuels, and bioproducts. Recently, the fund has announced the awarding of its grants to companies that are committed to this sustainable future. CAAFI is pleased to see that two of the grants awarded are focused on sustainable aviation fuel (SAF).

Gevo, Inc. has been awarded more than $100,000 USD to evaluate sugarcane and wood waste resources in Queensland for their alcohol-to-jet-fuel conversion process. The alcohol-to jet process is qualified to be used as jet fuel under Annex 5 of the ASTM D7566 Standard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons. Gevo currently operates a demonstration facility in Luverne, Minnesota that produces protein, animal feed and isobutanol. The isobutanol is then converted into renewable gasoline, diesel and jet fuel. The jet fuel made by this process has very low sulfur, low particulates, and slightly higher energy density than petroleum-based jet fuel. Gevo supplied the alternative jet fuel used in Virgin Australia’s SAF delivery trial at Brisbane Airport. Read the news release here for more information.

Licella Holdings also received funding from the Biofutures Fund in the amount of more than $325,000 USD to conduct a feasibility study for a biorefinery that converts sugarcane waste into biofuel using Licella’s Catalytic Hydrothermal Reactor (Cat-HTR) technology. Licella is partnering with University of Queensland and Burdekin Renewable Fuels, among others, to test their conversion process. This technology uses supercritical and near-supercritical water to convert a wide variety of low-cost, waste feedstocks and residues into high-value products. Queensland is looking to provide a processing option to address the 1.65 million tonnes of sugarcane bagasse produced in the region every year. For the article click here. To

Japanese consortium to study SAF production using Fulcrum Bioenergy’s technology

March 11, 2020 – Japan Airlines, Marubeni, JXTG Nippon Oil and Energy and JGC Japan have agreed to jointly conduct a feasibility study on supply chains using waste materials (industrial and municipal waste) to produce sustainable aviation fuel (SAF) in Japan using Fulcrum Bioenergy’s gasification and Fischer-Tropsch approach. The study will include the evaluation of plastic waste as a feedstock. Fischer-Tropsch technology is qualified to be used as jet fuel under Annex 1 of the ASTM D7566 Standard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons.

The study will assess waste collection and processing options, the conversion process, logistics of end-products, and the carbon emissions impacts. The study will take place from February to December of 2020, following which the partners intend to develop a demonstration site in the next few years, and are targeting commercial development around 2025.

Boom Supersonic Announces First Fully Carbon-Neutral Aircraft Program, XB-1

March 6, 2020 – Boom Supersonic, an aerospace company with the goal of building history’s fastest supersonic airliner, announced that its XB-1 test program would be fully carbon-neutral with the use of sustainable aviation fuels (SAF) and carbon offsetting. With the XB-1 program, Boom is integrating environmental considerations throughout the aircraft’s design, testing and operation. Blake Scholl, Founder and CEO of Boom, says the company is on a mission to make the world dramatically more accessible through supersonic travel. In January of 2019, Boom successfully conducted a series of ground tests running XB-1 engines using a blend of more than 80% SAF that confirmed the XB-1 program could safely use SAF. In June of last year, Boom announced its partnership with Prometheus Fuels to supply SAF during the remainder of the XB-1 test program. Prometheus’ technology removes carbon dioxide from the air and uses electricity produced from solar and wind sources to turn it into jet fuel. Boom plans to debut the first independently developed civil supersonic aircraft this summer.

French Industry and Government Agree to Promote SAF

February 12, 2020 – The French government recently announced their ambition to replace 50% of traditional jet fuel with sustainable aviation fuel (SAF) by 2050. The announcement came out of an 18-month collaboration between the French government and industry, including Air France, Airbus, Safran, Total and Suez, to define French SAF goals. This was the first public-private aviation initiative in France and laid out the following five recommendations for standing-up the SAF industry in France:

• Mobilize the necessary volume of feedstocks to support the aviation sector
• Ensure sustainable resources are used to produce SAF
• Ensure value for all players throughout the supply chain through appropriate incentives
• Use existing airport logistics networks
• Support and promote production diversification

Alongside the government’s ambitions, the group of industrial entities announced the launch of a new Call for Expression of Interest (CEI) as a first step towards burgeoning the SAF industry in France. The CEI is expected to provide support and incentives for investments in SAF production facilities in France.

The French government and industry are working together to cultivate a welcoming environment for advancements in favor of a sustainable aviation fuel industry in France.
