Recycled CO2 in the form of methanol will work very well. Use nuclear powerplants to collect CO2 from existing ones and make hydrogen to convert it to methanol. Sodium is another option for a fuel for fuel cells. Sodium is liquid at the temperature of boiling water. Sodium potassium mixtures can be liquid at room temperatures. Actually the mixture can be oxidized with air to produce high temperatures for a steam car. Service stations can wash the ash out of a holding tank for recycling or making glass or biodiesel. A water sodium fuel cell can produce electricity and also produce hydrogen for burning in an engine. For the present and in the future, ZEBRA batteries will combine liquid sodium with nickel(or iron) cloride and separate them again at recharging at far lower energy cost than hydrogen storage. Also they are much cheaper and easier to build than fuel cells. ..HG..

Will these tanks be distributed to individuals and be capable of storing hydrogen for 15 years - until we have affordable fuel cell cars and infrastructure?
