The future of transport decarbonization is here, and it's a complex blend of alternative fuels and strategic policies. But which path should we take? The Oxford Institute for Energy Studies delves into this question, analyzing the economic and environmental viability of various drop-in liquid fuels for hard-to-electrify sectors like aviation and heavy-duty transport.
The study's focus: Evaluating four production methods for Renewable Diesel (RD) and Sustainable Aviation Fuel (SAF), namely HEFA, FT, ATJ, and eSAF/PtL, across the EU, US, and Brazil. And here's where it gets intriguing: the costs and benefits vary significantly.
Cost Breakdown:
- HEFA: $1.6-$1.1/kg, with feedstock as the primary cost driver.
- FT: $1.6-$1.4/kg, where capital and site services dominate expenses.
- ATJ: $2.1-$1.6/kg, with a higher cost range due to feedstock and alcohol logistics.
- eSAF: $5.3-$5.0/kg, sensitive to energy inputs and clean hydrogen costs.
The Hydrogen Factor: Hydrogen requirements differ, with eSAF being the most hydrogen-intensive. But the real controversy? The study suggests that the viability of these fuels is closely tied to hydrogen pricing and CO₂ costs, which could spark debates on the future of hydrogen-based economies.
Policy Implications: The paper proposes a strategic approach, suggesting immediate scaling of HEFA and FT with blending credits and feedstock support. ATJ should be expanded where alcohol logistics are advantageous, and eSAF should be developed as clean hydrogen becomes more affordable. But is this the best approach? The proposed policy design is a delicate balance, and opinions may vary.
