So another market that might make sense for the big refiners to jump into licensing G100UL would be the off highway market. Total sales is over 7 Billion gallons / year with boats and powersports equipment making up about 3 billion gallons of that. Avgas is only about 150 million gallons but it might make sense to formulate, market and sell one type of fuel. The perceived value of “aviation gasoline” might help the profit margin as well. Expanding the potential market by 20x could be a good thing for everybody. I would sure love to run G100UL in my paramotor, side by sides and my race car!
Data is old (2014) but the numbers make the example valid- https://www.fhwa.dot.gov/policyinformation/pubs/pl17012.pdf
