Maybe we should just admit that the future is unpredictable, especially the hydrogen economy. Just recently, we've seen Toyota predict the cost of hydrogen will be between $5-and-$7 per kilogram in the future. UC Davis also recently released a report that says hydrogen can be inexpensive in the future, but that likely continued fracking for natural gas will be necessary. But what if it isn't?

Hydrogen is being widely pursued as a fuel sources because it produces no greenhouse gases when used in either combustion of fuel cells. Producing hydrogen can be problematic though since pure hydrogen is rare. Scientists in Germany and the United States are working on yet another possible mechanism to create hydrogen gas. Researchers from the Max Planck Institute, the Technical University in Berlin, the Free University in Berlin and the Lawrence Berkeley National Laboratory are trying to unders
