There have been advancements in hydrogen storage beyond compressed hydrogen gas that look promising. One advanced hydrogen storage method involves a series of magnesium disks that bind hydrogen via microwave and release hydrogen via the action of a laser. The total weight of the system looks to be less than that of a 10k PSI high pressure tank. See http://plasmakinetics.com/ for more information.

At USC, research into generating hydrogen on demand from water using so called aluminum superatoms is benefiting from a computer model developed in Japan. The idea is that a chemical reaction will take less energy than brute force electrolysis where the aluminum can be recycled easily. This aluminum and water technique to produce hydrogen could be equally applied to on car and off car production. This method of hydrogen production would work well in a distributed system. In a distributed system, hydrogen would be produced at refueling stations instead of at central locations. This decentralized production would obviate the need for expensive pipelines and super cooled tanker trucks. I have Hydro Kevin who runs the hydrogen cars now blog to thank for this information.

The hydrogen car blog by Greg Blencoe appears to have been largely static over the course of the past three months. I don't know if Greg's company is in financial trouble or busy building hydrogen pipelines. Hopefully, Greg's company is doing well and he will add new information to his blog soon.

As far as I know, the Volt is still on track to be produced in November 2010. All I can say is too bad GM isn't moving on and producing the hydrogen fuel cell version. So the Volt is 8 months away from being produced.

With hydrogen cars becoming economically viable by 2015, that is about 57 months and hopefully a new president away. Obama pushing batteries as a short term way to address the imminent Oil crisis is bad policy.
