Oil companies and auto manufacturers buy up almost every alternative fuel patent they can get their hands on, hell they even buy ones that arent remotely feasable incase that one genius kid figures it out. Then when oil goes to the shitter they make money of "Their" ingenius alternative fuel idea. Hence why all of their alternative fuel ideas are still "in the works" as you say, they will remain there until the market is in demand of them. its all simple economics.
