The Most Promising Storage Method

Thank you all for your informative presentations. We have come to understand much about the methods of storing hydrogen. It seems appropriate not to completely invest solely in one technology, as each method has its benefits as well as drawbacks.

Compressed hydrogen is a reasonable method for long term storage, as it requires no energy to maintain compression. It does seem unlikely, however, that each automobile have a compression system and large volume tanks on board.

Liquid hydrogen is also very feasible for storage, as it demands less volume than gaseous hydrogen. There is a large maintenance fee to keep a refrigeration system constantly running, so automobile implementation is not so likely as well.

Concerning the methods not currently available, yet very promising, all three are likely to be the standard method of storage in individual vehicles, though novel breakthroughs in research must be made before their wide scale debut. It cannot be predicted which technology will breakthrough first, though we must remain persistent in our research efforts, as the importance of alternative fuels and clean energy cannot be stressed enough.

It is imperative that no one method be considered superior and others excluded, as each storage method is unique and beneficial in its own regard. On behalf of the U.S. Department of Energy I would like to thank you for joining us today, and have a pleasant afternoon.
