Advanced SAF Feedstock Pathways: Comparing HEFA, AtJ, FT, and Alcohol-to-Jet Production Economics for FBO Buyers

Technical comparison of Hydroprocessed Esters and Fatty Acids (HEFA), Alcohol-to-Jet (AtJ), and Fischer-Tropsch production pathways.

Executive Summary & Infrastructure Context

Sustainable aviation fuel (SAF) infrastructure, blending systems, and book-and-claim supply chains require rigorous engineering precision and regulatory compliance. This technical brief outlines the core operational standards necessary to deploy green fuel solutions across executive aviation facilities.

Primary Intelligence Question

What are the essential engineering and supply chain requirements for FBOs to ensure compatibility, operational integrity, and regulatory compliance when deploying high-blend sustainable kerosene derived from HEFA, AtJ, or FT pathways?

Key Intelligence

The brief identifies three critical engineering upgrades—legacy tank modifications, elastomer seal replacements, and filtration skid adjustments—to ensure full compatibility with high-blend sustainable kerosene. Supply chain integrity demands dedicated bowser fleets, static dissipator additives, and adherence to ASTM D7566 testing protocols, alongside immutable book-and-claim ledger systems to verify Scope 3 carbon reductions. Regulatory compliance is further reinforced by partnering directly with certified green fuel producers and specialized civil engineers to avoid intermediary markups. These measures collectively address technical, operational, and verification challenges for FBOs integrating SAF infrastructure.

Technical & Structural Framework

• Fuel Farm Engineering: Upgrading legacy tanks, elastomer seals, and filtration skids to ensure 100% compatibility with high-blend sustainable kerosene.
• Ledger Verification: Implementing immutable book-and-claim accounting frameworks to capture verified Scope 3 carbon emission reductions.
• Supply Chain Integrity: Managing dedicated bowser fleets, static dissipator additives, and rigorous ASTM D7566 quality testing protocols.

Strategic Directive: Partner directly with certified green fuel producers and specialized civil engineers to streamline sustainable infrastructure deployment without intermediary markups.

Summary & Next Steps

For family office operators and airport developers, integrating direct-source sustainable fuel infrastructure ensures long-term regulatory compliance and ESG leadership.

Frequently Asked Questions

Q1: What are the three primary SAF production pathways compared in this brief for FBO buyers, and what is their overarching focus?

A1: The three primary SAF production pathways compared are Hydroprocessed Esters and Fatty Acids (HEFA), Alcohol-to-Jet (AtJ), and Fischer-Tropsch (FT). The overarching focus is on their technical and economic feasibility for integrating sustainable aviation fuel infrastructure into Fixed-Base Operations (FBOs).

Q2: What are the three critical engineering and operational standards required for deploying high-blend sustainable kerosene in legacy fuel farms?

A2: The three critical standards are:

• Upgrading legacy tanks for compatibility with high-blend SAF,
• Replacing elastomer seals to prevent degradation from SAF properties,
• Modifying filtration skids to ensure proper handling of SAF blends.

Q3: What supply chain and regulatory measures must FBOs implement to ensure the integrity of their SAF supply chain and compliance with ASTM standards?

A3: FBOs must implement:

• Dedicated bowser fleets for SAF transport,
• Static dissipator additives to mitigate electrostatic hazards,
• Rigorous ASTM D7566 quality testing protocols for fuel verification,
• Immutable book-and-claim accounting frameworks to track Scope 3 carbon reductions.
