Sustainable Aviation Fuel (SAF)
Project Advisory
Sustainable Aviation Fuel (SAF) has emerged as a pivotal decarbonization lever for the global aviation sector. For institutional investors, corporates, and project developers, SAF is no longer a niche sustainability initiative — it is a strategic capital allocation decision shaped by evolving policies, feedstock dynamics, and rapidly advancing technologies.
At Trident, we advise clients at the intersection of technology pathways, financial structuring, and regulatory foresight, helping them navigate uncertainty and build bankable, future-proof SAF portfolios. Our approach moves beyond conventional technical consulting by embedding policy intelligence and investment rigor into every decision framework.
Why SAF Demands an Integrated Advisory Approach
SAF project viability depends on aligning three critical forces: technology maturity, credit economics, and policy trajectories. Traditional engineering or financial advisors often focus on one dimension in isolation, leaving investors exposed to risks that materialize years after capital is deployed.
Key Drivers We Address
-
Policy Windows & Incentives
The U.S. landscape shaped by OBBBA, 45Z tax credits, LCFS markets, and Section 232 determinations directly impacts IRR and offtake economics. In parallel, EU frameworks like ReFuelEU and RED III dictate sustainability eligibility for global pathways. -
Feedstock Optionality & Compliance
From waste lipids to municipal solid waste and cellulosic residues, feedstock strategies must balance cost, carbon intensity, and policy alignment — especially as CI scoring rules evolve. -
Pathway-Specific TRL Risks
Each SAF production pathway — from HEFA to emerging pyrolysis-to-jet (HDCJ) — sits at a different stage of Technology Readiness Level (TRL), shaping its scaling risk and capital requirements. -
Capital Structuring for Resilience
Credit stacking across 45Z, LCFS, and compliance markets must be integrated into financing structures to ensure returns remain robust under downside policy or market shifts.
Pathways We Support – From Today’s Leaders to Tomorrow’s Innovators
The SAF landscape is rapidly diversifying. Trident provides advisory coverage across current commercial routes and emerging technologies, helping clients allocate capital with precision.
Current Commercial Pathways
These are the most established SAF technology pathways with relatively lower TRL risk with an improving or sustainable potential:
-
HEFA (Hydroprocessed Esters and Fatty Acids)
Mature technology, scalable today, but feedstock cost volatility and declining policy incentives can erode margins. -
Alcohol-to-Jet (AtJ)
Attractive for regions with abundant low-CI ethanol or waste alcohols; ASTM-approved and scaling, but sensitive to feedstock availability. -
Fischer-Tropsch (FT)
Suitable for large-scale projects utilizing syngas from biomass or waste; high capex and long timelines require strong offtake and policy certainty.
Emerging & Future Pathways
These technologies represent the next wave of SAF, with higher uncertainty and upside potential.
-
Pyrolysis-to-Jet (HDCJ – Hydrotreated Depolymerized Cellulosic Jet)
-
Converts waste streams such as municipal solid waste, agricultural residues, and plastics into SAF.
-
Currently at TRL 6–7, with ASTM approval processes underway.
-
Success depends on scaling yield, supply chain logistics, and downstream hydrotreatment economics.
-
-
E-Fuels / Power-to-Liquids (PtL)
-
Synthetic SAF produced using renewable hydrogen and captured CO₂.
-
Long-term strategic pathway requiring deep renewable power integration and careful regional siting.
-
Investment Decisions That Define Project Outcomes
Our advisory process integrates technical analysis with financial modeling and policy foresight to create actionable, investment-grade strategies.
Dimension | Strategic Value |
|---|---|
Credit Architect | Optimize credit stacking to improve returns under base, upside, and downside scenarios. |
Policy Intelligence Embedded | Anticipate shifts in CORSIA, EU Fit for 55, LCFS, OBBBA, and global mandates, integrating them into long-term decision models. |
Financial Structuring & IRR Modeling | Build IRR/MOIC sensitivity models factoring in credit markets, offtake risk, and policy sunset timelines. |
Technical & TRL Assessment | Align project timing and scaling decisions with real-world technology maturity to avoid stranded assets. |
This integrated approach provides clarity to investors navigating multiple variables — from ASTM /EN certification timelines to cross-border regulatory arbitrage.
Pyrolysis-to-Jet as a Strategic Opportunity
While HEFA and AtJ dominate near-term deployment, HDCJ represents a critical next-generation pathway:
-
Technology Edge: Ability to process low-cost, abundant feedstocks including waste plastics and agricultural residues.
-
Policy Fit: Aligned with future sustainability mandates under OBBBA and ReFuelEU as “advanced biofuels.”
-
Investment Challenge: Capital deployment must be staged, with pilot-to-commercial scaling steps tied to policy windows and ASTM progress.
Trident helps clients design portfolio strategies where today’s commercial SAF provides stable returns, while emerging pathways like HDCJ create optionality and upside.
Policy Intelligence – Embedded, Not Isolated
Policy is not a separate advisory service — it is integrated into every investment decision we make.
-
OBBBA and 45Z (U.S.): Align project timing with credit eligibility phases and sunset clauses.
-
LCFS and Regional Credits: Manage downside risk from volatile credit pricing.
-
EU RED III and ReFuelEU: Guide cross-border compliance for international offtake structures.
-
CCA & Section 232: Anticipate trade policy implications on SAF feedstock and finished fuel flows.
This ensures projects are resilient to policy shifts, not merely compliant at a single point in time.
