Hydrogen, the ultimate clean fuel, may not be very suitable as a conduit of renewable energy because it is wasteful and there are better alternatives, scientists said.
One reason that hydrogen is embraced by politicians like US President George W Bush is that it promises a source of power for cars and buildings that emits only water.
The drawback is that hydrogen must first be produced, requiring a primary energy source, and this is where scientists see major obstacles.
