There is really no information at all about how it works, but some Danish scientists have received a patent for storing hydrogen in pill form.
Apparently, this new process is highly efficient, and can store enough hydrogen for a car to travel about 300 miles in the space of a normal 12 gallon tank. No other hydrogen storage system has come close to the same level of efficiency.
Questions still remain, like how much energy is required to produce the pill form of hydrogen, but it is one more sign that the Energy Economy is gearing up for some boom years.
