Swoop223 emission in an engine come from the heat of the burning fuel, if you can lower the burning heat and make the ignition process better you can lower the emissions, now LPG are nearly there but this process is there Pluss its more efficient than LPG. You then add this to like you said a hybrid system and you get what you need a low rpm engine with 100% zero emission. Tis fuel has been around as a fuel sine the 1930's so its not new but because of the hydrogen interest it has been over looked for now.
As Hydrogen is not very good because of a number of issues then this fuel is able to offer a better alternative, You must understand I didn't come up with this solution, I was lucky enough to meet some very top experts in the field of hydrogen these told me about this fuel and why it would be better. These guys have been building hydrogen fuel cell since the early 90's so they do know what they are talking about
