Problems with a hydrogen economy

The hydrogen economy without a doubt will help reduce the level of carbon dioxide in our atmosphere, however in order to implement a hydrogen economy we have to solve a number of problems. One problem concerns the storage of hydrogen because in order to use hydrogen in our cars we need to be able to store it at a low temperature. The other problem is the transportation of hydrogen from one state to another. Finally, the serious problem has been stated by a computational physicist named Kyeongjae Cho at Stanford University;

(As a reminder: in a fuel cell, a catalyst strips electrons from hydrogen atoms to generate electricity. A catalyst consists of nanoparticles of platinum.)

"However, platinum is not a cheap metal, and it's a finite resource," says Cho. "There will be lots of problems if we try to launch a hydrogen economy based on fuel cells, because we don't have enough platinum to do the job." [1] Read on to learn more about the approaches researchers are using to tackle this issue.

The issues mentioned above are the main three problems to developing a hydrogen based economy. With that in mind we will now explore each problem separately to see where researchers are at and to get a closer look at how these problems are being solved.
