Flexjet parent invests in next-gen sustainable fuel producer

Directional Aviation is investing in clean tech developer Alder Fuels to scale-up second-generation SAF

Flexjet parent Directional Aviation is making a financial investment in clean tech developer and green crude producer Alder Fuels.

As part of the agreement, the two companies also will pilot a pioneering blockchain-powered transparency tool to document the production life cycle and industry adoption of low-carbon SAF.

The state-of-the-art tool will assist with transparency around the production of SAF and provide robust documentation for compliance with regulatory programs, environment, social, and governance (ESG) targets, and carbon reduction milestones for the aviation sector.

Scalable Sustainable Aviation Fuel

Alder Fuels uses sustainable biomass, such as regenerative grasses, forest residues, and agricultural waste products, to create a low-carbon to carbon-negative green crude that can be converted into SAF using existing bio and petroleum refinery infrastructure.

In contrast to first-generation SAF, which was generated primarily from non-scalable supplies of fats, oils, and grease, these biomass sources are abundantly available and, when repurposed, can contribute to soil regeneration and wildfire mitigation, according to Directional.

When calculating the fuel production carbon life cycle from field to wingtip across different biomass sources, AGC-derived SAF can achieve greenhouse gas reductions of over 80% compared to petroleum jet fuel.

The process, which has been validated by the Department of Energy’s National Renewable Laboratory (NREL), could even be carbon negative when utilizing regenerative crops. 

AGC-derived SAF will meet current aviation specifications and is currently in the process of global certification as a 100% drop-in replacement for petroleum-based jet fuel. 

First private aviation customer

As part of the agreement, Flexjet will become the first business aviation user of this SAF.

“Our investment in Alder Fuels and partnership on advancing the use of digital technology to document SAF use is an example of private aviation leading the way on sustainability commitments and identifying solutions to reduce carbon emissions that aid the entire aviation industry,” said Kenneth C. Ricci, Principal, Directional Aviation.

“As we make the transition from fossil to sustainable energy throughout our economy, transparency is critical. It is how we engender trust and integrity to strengthen the adoption curve – and that is exactly what we are working towards at Alder Fuels,” said Bryan Sherbacow, Chief Executive Officer and President of Alder Fuels.

4AIR and Alder will align the use of blockchain technology tools to account for all the emission claims from the use of the SAF, generating the necessary records and transparency for compliance with regulatory frameworks, ESG standards, and other sustainability commitments.

“Our goal at 4AIR is to make sustainability as simple and cost-effective as possible in order to promote its growth,” said Kennedy Ricci, 4AIR’s president. “The use of blockchain technology to transparently and permanently record the use of sustainable aviation fuel is an innovative application that will help users with regulatory and voluntary compliance and provide greater transparency about SAF’s benefits as a way to reduce climate-changing aircraft carbon emissions.” 

Flexjet sustainability goals

Through this partnership between Directional and Alder Fuels, Flexjet will be the first business aviation offtake partner for AGC, advancing Flexjet towards its goal of having 12% of its annual fuel consumption come from SAF by 2030. 

“Flexjet has achieved carbon-neutral flight operations for the past two years, purchasing credits to offset emissions from all flights booked by our aircraft owners worldwide,” said Flexjet Chief Executive Officer Michael Silvestro.

He added, “However, we have wanted to take the next step, not merely offsetting emissions but actually reducing them directly in our operations by taking tangible steps today. The use of SAF produced with Alder’s cutting edge green crude will help us achieve this goal, maintaining our leadership on aviation sustainability, and the transparency tool developed by Alder Fuels and 4AIR will serve as a real-world proof of concept.” 

The recent passage of the Inflation Reduction Act into law amplifies the U.S. commitment to SAF by providing tax credits for every gallon produced that demonstrates a 50% or greater lifecycle greenhouse gas emissions reduction relative to petroleum jet fuel. 

Last year NetJets announced an investment in SAF producer WasteFuel.
