Happy Earth Day!

22 April 2018 - On April 22, 1970 millions of people came together on one day to highlight and protest the negative impacts of uncurbed industrial development. Just months later, responding to the outcry, President Nixon created the EPA and later enacted many laws to protect the environment, including the Clean Air and Clean Water Acts. 48 years later, for CAAFI, every day is Earth Day; we’re working to improve the environmental performance of aviation with sustainable alternative jet fuels, including developing supply chains that improve water and air quality while reducing GHG emissions. Please join us in helping reduce aviation’s negative impacts on the planet. Happy Earth Day!

Co-Processing Provision Approved and Added to ASTM 1655 Annex A1, Enables Renewable Feedstocks in Jet Fuel

18 April 2018 - The Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants, as well as their D02.J0 Sub-committee on Aviation Fuels, have approved the co-processing of renewable feedstocks with crude oil-derived middle distillates in petroleum refineries. The concurrent ballot was issued in February to the subcommittee and committee. The co-processing provision will be added to Annex A1 of ASTM D1655, Standard Specification for Aviation Turbine Fuels, and should be published imminently. The Annex will initially include co-processing of up to 5% by volume of fats and oils (free fatty acids and fatty acid esters found in oils derived from plants and animal fats) as feedstocks in petroleum refinery processes. The Co-processing Task Force will next work toward adding Fischer-Tropsch (FT) derived biocrude feedstocks to the annex. CAAFI welcomes this additional approach toward alternative jet fuel commercialization, and looks forward to further engagement with existing refineries on ways to achieve increasing volumes of sustainable fuel production.

Ethanol Added as Approved Feedstock and Allowable Blend Levels Increased for ASTM Approved Alternative Jet Fuel Annex

18 April 2019 – Earlier this month, ethanol was added as an approved feedstock in ASTM 7566 Annex A5, the specification for Alcohol-To-Jet fuel, Synthetic Paraffinic Kerosene (ATJ-SPK). With CAAFI support, LanzaTech led the ASTM Task Force for ethanol based ATJ fuel produced using technology initially developed by the Pacific Northwest National Lab (PNNL) that LanzaTech has scaled-up. In addition to adding ethanol to the ATJ-SPK approved pathway, the blend ratio for ATJ-SPK was raised from 30% to 50% for commercial flights. LanzaTech is currently designing an ethanol-based ATJ-SPK facility that can produce 3 million gallons of alternative jet fuel and diesel using sustainable ethanol feedstocks. With this new revision of the ATJ-SPK annex, ethanol-based ATJ can be produced with ethanol from any feedstock, including industrial off gas, biomass wastes and residues, and municipal solid waste. This flexibility enables ATJ-SPK to be produced in a sustainable manner from locally available sustainable feedstocks wherever a facility is located. CAAFI is pleased to see the addition of ethanol as a feedstock to ASTM 7566 Annex A5 and the increased blend ratio, which creates new commercial opportunities.

Global Bioenergies and SkyNRG to Collaborate on ASTM Certification of New SAJF Pathway

18 April 2018 – Global Bioenergies and SkyNRG have announced they will work together to qualify Global Bioenergies’ process for converting isobutene to a sustainable alternative jet fuel (SAJF) through ASTM for use in commercial aviation. Global Bioenergies’ pathway entails oligomerization and hydrogenation of isobutene produced from forestry or agricultural wastes to C12 isoparaffins. Global Bioenergies has sent fuel produced in Germany to SkyNRG for preliminary analysis. The aim of the partnership is to accelerate the commercialization of this alternative jet fuel pathway. CAAFI welcomes this partnership and their entry into the ASTM qualification process as another pathway to a more secure and sustainable aviation future.

UK Adds Alternative Jet Fuel into RTFO Scheme for Reducing GHG Emissions

18 April 2018 – The UK Government is updating its Renewable Transport Fuel Obligation (RTFO) GHG emissions reduction scheme to increase the biofuels volume target and include alternative jet fuel. The RTFO requires suppliers of transport and non-road mobile machinery fuels greater than 450,000 liters to show that a percentage of their fuel comes from sustainable sources to encourage renewable fuel production resulting in a reduction in GHG emissions from the transportation sector. The RTFO legislation was passed in 2007 and has been amended five times since, with the latest taking effect April 15th. This latest amendment brings alternative jet fuels under the RTFO scheme, making jet fuel producers eligible for incentives that were previously only available for road transport fuels. The goal for including alternative aviation fuels alongside road transport fuels is to support the UK’s low carbon fuel industry in making the UK’s transport sector one of the most sustainable in the world.
