Right, and ultimately, hydrogen is one of the most (if not THE most) efficient energy storage methods. However, as far a physical storage, actually putting it in a tank, it is not as efficient. Plus, burning it is not as efficient as electricity either. Electricity and batteries are the way to go. They are around 90% efficient today and will only get better with better cooling methods and recapturing heat loss/preventing heat.
