Thanks for the post, I was not aware of that. Most of the anaerobic biogas I had heard of was being used directly for heat on site or to produce energy, but I assumed they were using gas generators, not fuel cells. I heard a huge push on fuel cells back in 2000, and then after 9/11 I never heard much more about them, I figured it was the price of CH4 that killed them, and the problem with throttling their output, and the slow start and stop issues, as they are not instant on, off yet, the last time I heard.
For those have PM'd me, I don't have access to the PM service here, just the free services, so if you want to chat back channel, PM me an email ady.
