Making Natural Gas Transportation a Reality

The pipeline cost of natural gas is only 1/4th of the cost of crude oil with the same energy content. If much simpler, 500 psi Adsorbed Natural Gas  refueling is adopted, prices could be reduced even further..
ANG fuel tanks contain activated carbon “sponges” that adsorb 160 times their own volume of natural gas. They can be made from Corncobs , which have a network of nanoscale passageways that remain after carbonization.  One gram of this material has as much adsorbing surface area as a football field. When natural gas is adsorbed on a carbon surface it ceases to act like a gas. Dense storage at low pressure makes it possible to hide the much smaller tank inside the car's frame.
