[...] The launch of Bloom Energy’s fuel cells has refocused the energy industry on just how to get this decades-old technology to compete on a cost basis with traditional forms of energy generation. For most fuel cell makers, that means finding niche markets — data centers, perhaps, or remote cellular base stations, or wastewater plants that generate their own biogas. [...]

Thanks, Michael -- I was referring to the difference between running methane through a fuel cell, which produces CO2, and burning it, which does indeed produce NOx and other chemicals.

In the second to last paragraph you mention other chemical byproducts of methane combustion. What are the other chemicals that come from burning methane? Doesn't combusted CH4 turn into just CO2 and H2O? Are you referring to NOx, or are there others?

Gosh Jeff,

Your such a party-pooper. Didn't you get the industry flag waving memo?

Just kidding. Good journalism, as usual.

Tangled Up in Bloom,
