Will hydrogen fuel cell technology never develop because it can’t be taxed like gasoline?

Gasoline, diesel, and even biofuels can carry a per gallon federal tax. Federal tax on fuel exceeds oil company profits on fuel. Revenue from fuel tax is a major source of income for the treasury.
Federal money is being spent to develop biofuels rather than hydrogen fuel cells, a cleaner form of energy. Our we losing out on better source of energy because it can't raise the same amount of tax revenue as crude oil?

Which route will give the auto industry its best chance of survival?

The U.S. auto industry is in turmoil, it has spent too many years building inefficient vehicles. Which route will give the auto industry its best chance of survival as the gasoline supply starts to dry up: hybrids, natural gas, hydrogen, fuel cells, electric, steam ? Explain your answer.

What about alternate fuel sources for airplanes, trucks, etc?

So all this research that is going into hydrogen fuel cells, hybrid technology, and other alternate energy sources for automobiles, is there any corresponding research for airplanes or trucks, or other such things that require huge amounts of fuel, whether it is jet fuel or diesel fuel?

Is hydrogen fuel-injection more potent than hydrogen fuel cell?

What is the energy difference (energy output) in hydrogen burning in a fuel injection (combustion) engine and hydrogen used in producing electricity in hydrogen fuel cells? Gasoline power is stronger.

BMW has made a hydrogen fuel-injection based car, meaning this is not a hydrogen fuel cell, but the same engine used for burning gasoline, but now it burns hydrogen instead. The car is found here.


What I am wondering is, that if hydrogen gas when burned is the same potent as gasoline, then shouldn't a fuel injection engine be more powerful than a fuel-cell electric engine? My particular interest if the two are different energies (battery cell vs. hydrogen combustion). If hydrogen combustion produces more horsepowers, then that extra energy could theoretically make up for the 30-40 percent energy loss in making hydrogen.
