So essentially my opinion? It isn't a sure belief but you know what, it's possible, and I'm not ignorant to assume its a complete impossibility. You may same I'm a fool, or a conspiracy nut, and I may think you a narrow minded cog in the machine of society. I just have an imagination along with a logical mind.
At the end of the day it's an example to highlight humanities lack of priority when it comes to bettering the planet, along with the human race itself. Not just fuel. Human injustice, religious attacks, terror threats, unequal wealth distribution etc. You're right I don't understand the chemistry behind it and never said it was be 100% pollutant free. Could be lessened with enough research. In 100 years if we're still using combustible fuel as a standard I'll be surprised as well as dead.
