I’m doing some research on fuel cells. I’ll be looking at the cells themselves; hydrogen as an energy carrier; and distribution and storage questions. I plan do to couple of posts over the next few days.

The dimensions you need to consider to assess any energy technology include:

• efficiency
• greenhouse gas emissions
• cost

and depending on the application, there are other factors that can be very important, including:

• size
• weight
• operating temperature

There is a lot of material out there on fuel cells, and I’m combing through some of it now to compile some initial thoughts. In the meantime, if you have any favorite sources, feel free to comment here and post links to them. Thanks.
