At least in northern Europe, Diesel engines are critical to the agricultural industry. Considering some farmers are still using 40 year-old tractors around here, I doubt the Diesel engines will go away any time soon. But one of the advantages of Diesel engines are that they aren't really that picky when it comes to fuel. I don't think the engines are going anywhere, but we're probably going to see more and more non-fossil Diesel alternatives being used in the future.
