Need proof that the hydrogen issue is still far from being settled? As usual, Jeremy does not disappoint. By the way, I still want a Clarity FCX on my driveway !!! :D --Ed.

Why keep living the hydrogen fuel cell dream?

Auto makers favour fuel cells for two main reasons: no need for petroleum and no emissions from the tailpipe. A fuel cell uses hydrogen to generate electricity through a chemical reaction and emits only water vapour through the tailpipe. Hydrogen is plentiful and can be derived from natural gas, methanol and even water.

Compared to other so-called “green” transportation technologies – gasoline-electric hybrids, plug-in hybrids and battery-powered vehicles – hydrogen fuel cell-powered vehicles could be a promising way for car companies to meet stiffer CO2 regulations later this decade.

So what’s in a fuel-cell powertrain? Four main elements:

1. A tank that stores hydrogen.

2. A fuel-cell stack that converts hydrogen and oxygen into heat and water, creating electricity.

3. Lithium-ion batteries that store the electricity.

4. A power unit that controls the flow of electricity to the electric motors that propel the vehicle.... http://www.theglobeandmail.com/globe-drive/green-driving/news-and-notes/two-reasons-to-push-for-hydrogen/article1953460/
