Storing Hydrogen At Room Temperature 152

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."

    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.
