Storing Hydrogen At Room Temperature

cylonlover writes "Hydrogen storage, along with hydrogen production and the lack of infrastructure, remains a major stumbling block in efforts to usher in hydrogen as a replacement for hydrocarbon-based fuels in cars, trucks and even homes. But with the multiple advantages hydrogen offers, developing hydrogen storage solutions has been the focus of a great deal of research. Now an MIT-led research team has demonstrated a method that could allow hydrogen to be stored inexpensively at room temperature."

  1. An easy solution by ultranova · · Score: 5, Insightful
    I know an easy way to store hydrogen safely at room temperature: make a chain of carbon atoms, then join hydrogen atoms in the leftover "slots".

    Seriously, the whole idea of "hydrogen economy" is simply stupid. It's not going to do anyone any good unless you have a power source to produce the hydrogen; and if you have said power source, it really isn't that hard to crack carbon dioxide and water to produce hydrocarbons rather than just water to produce hydrogen. Either produces carbon-neutral fuel, but hydrocarbons are far safer to store and use and hold more energy per mass or volume unit. Hydrocarbons also have the advantage of being compatible with existing vehicles and distribution network, being another name for oil.

    The final nail in the coffin of hydrogen is that biofuels are hydrocarbons. That's understandable, since biofuel projects are simply trying to mimic, hasten and optimize the same processes that formed oil in the first place. However, that means that a hydrogen-burning vehicle can't use biofuels, at least not without losing massive amounts of efficiency.

    Forget magic. Any technology distinguishable from divine power is insufficiently advanced.

  2. Sure. After all, Platinum now costs less than Gold by tp1024 · · Score: 5, Interesting
    At least it did this morning. Might have changed until now. However, quote:

    Sow-Hsin Chen, MIT professor emeritus in the Department of Nuclear Science and Engineering and senior author of a paper describing the new method, says it should make it possible to increase the storage capacity of the activated carbon material by fine-tuning the size and concentrations of the particles of platinum and carbon. The team also hopes to identify a catalyst that isn't quite as expensive as platinum.

    So who the hell approved a story that says "Now an MIT-led research team has demonstrated a method that could allow hydrogen to be stored inexpensively at room temperature." If you follow the link it says that a way to inexpensively store hydrogen at room temperature is exactly what they haven't found.

  3. Ozone layer holes by pr0f3550r · · Score: 4, Interesting
    This is important and significant because Hydrogen is very bad for the Ozone layer. Loose hydrogen is so light that it attempts to leave earth and settles in the upper layers of the heterosphere or is whisked off into space. However, many molecules of H2 never make it that far because they are very reactive in the presence of ozone. Research from Caltech indicates that Hydrogen In the upper atmosphere they can easily turn to H2O and produce the harmful presence of upper atmosphere water. Eventually this will fall back to earth but it will have unintended consequences as H2 is ozone depleting and water is an inhibitor to ozone creation.
