Drop-In or Drop Out The Technical Limits of Sustainable Aviation Fuel

Drop-In or Drop Out: The Technical Limits of Sustainable Aviation Fuel
by Peter Kakljugin

What if the future of flight hinges on the chemistry of a single drop?

In Drop-In or Drop Out, aerospace engineer and energy analyst Peter Kakljugin takes readers inside the critical, and often misunderstood, world of sustainable aviation fuel (SAF). With carbon reduction targets looming and the aviation industry under increasing pressure to decarbonize, SAF has emerged as a promising solution. But can it truly deliver?

This authoritative work breaks down the technical, economic, and logistical boundaries facing SAF adoption at scale. From jet engine performance and fuel certification standards to production bottlenecks and lifecycle emissions, Kakljugin offers a deeply researched, candid look at what's technically feasible-and what isn't.

Whether you're an aviation professional, climate policy expert, or simply a curious traveler of the skies, this book will change how you think about the future of flight.

Explores:

• The physics behind SAF and jet fuel compatibility

• Engineering limitations of drop-in replacements

• Realistic pathways and pitfalls to 2050 emissions goals

• Why some "green" solutions might be taking us off-course

Clear-eyed, insightful, and grounded in science, Drop-In or Drop Out is an essential read for anyone invested in aviation's role in the global energy transition.
