Here's a possible solution to one of the most pressing problems of the
hydrogen economy and the widespread use of fuel cell vehicles: how do we
store the hydrogen efficiently and safely? As these researchers at the
University of Chicago have put forth, the answer may be to essentially
freeze it into a form called hydrogen clathrate hydrate. Once in this
form, it remains perfectly stable at regular air pressure (atmospheric
pressure) as long as you keep it very cold (-320 degrees F). This
suddenly makes hydrogen relatively easy to store, and if the research
holds out, it means that existing gas stations could be retrofitted with
hydrogen storage units at far less cost (and with far greater safety)
than previously thought. And that's good for the hydrogen economy.
Naturally, these solutions will take years -- maybe decades -- to make
it into mainstream use, but this is precisely the kind of good science
necessary to lay the foundation that allows the world to finally move
away from our outdated oil economy and into something cleaner, smarter
and far more environmentally friendly.
