Farrell and Keith, associate professor of engineering and public policy at Carnegie Mellon University in Pittsburgh, noted that hydrogen is derived mostly from oil and coal, which produce substantial carbon dioxide.

That is a huge pile of shit. The single largest source of hydrogen on Earth is water, and all you need to do to get it is zap it with electricity.
Admittedly, there are some efficiency issues regarding getting the hydrogen, but I have read of several developments in hydrogen fuel cells that recycle the water exhaust that is produced by using some of its own power. Other proposals suggest using solar or wind power to set up big hydrogen extraction facilities.
Hell, they could even use the hydroelectric power that's all over Canada's north.
The only thing that's at risk by switching to hydrogen is the oil companies.
