Bioengineered algae bringing hydrogen fuel-cells closer? {Autoblog}

Mar 8th 2006 1:02PM The use of hydrogen fuel excites my imagination as a great alternative to fossil fuels. Given some of the articles I have read on this, I have to wonder why we don't see commercial use of hydrogen fuel cells, retrofitting oil or coal fired applications. A large factory would have surplus space to accommodate the generation and storage of hydrogen.

I would also think there is an industry waiting to launch whose sole purpose is retrofitting fuel cell technology into existing steam producing devices fired by fossil fuels.

What are the obstacles keeping this technology from taking off, aside from politics?
