Looney Dunes: Hydrocarbons

And now I found this : An Early Retirement For The Hydrogen Fuel Cell | EnergyBulletin.net | Peak Oil News Clearinghouse

Excerpt:
At last weekends Lucerne Fuel Cell Conference, which is a highly respected technical conference, Ulf Bossel, the organizer, made a pretty signinficant announcement: the European PEMFC Forum series will not be continued because hydrogen fuel will never contribute to a sustainable world. Instead they will focus on phosphoric acid fuel cells, molten carbonate fuel cells and solid oxide fuel cells which "can meet the challenges of a sustainable future".

And more:

Fuel cells are energy converters, not energy sources. They will be part of a sustainable energy solution only if they can compete with other conversion technologies. This includes system parameters, fuels and applications. Time has come for a critical assessment.

We need fuel cells for available fuels, not synthetic fuels for new fuel cells. Natural gas and oil-derived liquid hydrocarbons will be around for many years. However, their use will be restricted by costs, environmental concerns or even political reasons. Sustainable hydrocarbons like bio-methane, bio-ethanol and bio-methanol from organic waste, wood or farming are already replacing fuels of fossil origin. Hydrocarbon fuels will be important forever and so will fuel cells capable of directly converting these fuels into electricity.
