If you consider a 15 to 20% energy loss "similar" I guess. I don't. And lets not even talk about the power loss. If you want to; go talk to some of the school bus drivers that went from diesel to NG and see what they have to say. You will get an ear full. :E
I'm not aware of any school bus MFGs that offer LNG. Many offer CNG, which is less energy dense. LNG and CNG are very different animals. There is no performance loss when using LNG. The primary disadvantage is the high conversion cost and limited fueling locations. Some fleets have started moving towards LNG
