Reducing the weight and cost of hydrogen storage tanks remains one of the technological issues that engineers must overcome to make fuel cell vehicles more practical. Aside from the large metal cylinders currently used in most applications, one of the primary options has been various types of solid state storage that absorbs and then releases the hydrogen.
It's no secret that a ton of problems need to be overcome before there's any real chance we'll all be driving clean-emissions hydrogen-powered cars and trucks. One such problem is how to store the hydrogen, which is a much less energy-dense fuel than gasoline. Researchers at the University of Delaware believe they may have found a possible solution from an extremely unlikely source: chicken feathers.
Three Greek researchers have developed a new set of carbon nanotubes (CNT) that could store safely hydrogen for fuel-cell car applications. These researchers - Georgios Dimitrakakis, Emmanuel Tylianakis, and George Froudakis - modeled a structure made up from parallel graphene sheets, that is, layers of carbon just one atom thick. Each layer was stabilized by vertical columns of carbon nanotubes and lithium ions that helped increasing the storage capacity. These layers were found to be able to s
Researchers at Rice University are studying a new way of potentially storing hydrogen within tiny carbon nano-structures called buckyballs. So far they haven't actually been able to physically test their ideas. They have only done computer simulations to evaluate whether the structures could hold multiple hydrogen atoms. A carbon buckyball made up of 60 carbon atoms can hold up to 58 hydrogen atoms before coming apart. The structure could be scaled up to create larger buckyballs to hold more hyd
There are many stumbling blocks when it comes to the successful use of hydrogen as an energy carrier for automobiles. Among those stumbling blocks is figuring out how to extract hydrogen in an environmentally friendly and cost effective manner, how to transport that hydrogen and subsequently refill a car with it, and where to put it once you've successfully managed to get around the first two. General Motors is working on the issues, as Sam recently reported. Universities all over the world are
Lets get two pieces of commentary out of the way right off the bat. One, who else thought of the movie Goonies when they read "pellets of power"? "Pinchers of peril, saved by my pinchers of peril"! - Data, aka Jonathan Ke Quan. Two, how awesome is the name "The Department of Energy's Chemical Hydrogen Storage Center of Excellence"? Maybe we should change our name from AutoblogGreen to "The Weblogs, Inc. Blog of Green Automotive News of Excellence". I like the way that rolls out, kind of like Wil
A research document led by Javier Bermejo, a scientist from the Basque Country University (UPV-EHU) in Spain and published in the Physical Review Letters magazine has shown "promising results" in the use of carbon nanostructures to store compressed hydrogen for automotive uses. The nano-storage units are called "nano-horns" and have a dahlia shape made up from "aggregated nanotubes that look like horns".
Carnegie Mellon has some interesting research going on these days. Those who oppose hydrogen as a fuel source (electricity) have quite a few problems to hang their hats on. For one, where to get the hydrogen from? Yes, it is abundant, but it is tied up with other stuff... making things such as water. Much of the hydrogen currently in use is captured from natural gas, which is expensive and has dubious environmental benefits. Another problem is hydrogen storage. What do you do with the hydrogen o
While the media buzz might make people believe hydrogen fuel cells are around the corner, significant hurdles still need to be crossed. Even though some prototype fuel cell cars are showing promise in delivering an experience similar to existing cars, cost, hydrogen storage, and lack of infrastructure are major issues. More importantly, though, in my opinion, is where is all the hydrogen needed to meet our transportation need going to come from? Unlike gasoline, hydrogen is not considered a fuel
