Earlie, Kyros and LLCF This has projected cost (in 03) for Molten Carbonate fuel cells -- 10 MW station. The PEM type which I think were the type being discussed on NPR have a much higher capital cost, but probably a little lower maint cost As you can see the cost/kw of the molten carbonate FC is roughly 4x the cost of the combined cycle eia.doe.gov if you take the inverse of the heat rate at the far right and multiply by 3,412 you can get the implied efficencies -- Molten Carbonate are a little more efficient than the combined cycle (63% vs 52 or 53% for an Advanced CC) -- I think PEMs are closer to the efficiency of a combined cycle, FWIW. I think the number mentioned on NPR was 50% Supposing you could get the capital cost of a Fuel Cell cut to 1/4 of current cost (for a significantly smaller installation -- that table has 10MW units -- that's a very big IF) -- might look good for someone in CA if you want to shell out thousands of dollars for a unit, but for most it would not be a good idea as they would give up the advantage of receiving gen from multiple types of sources through their utility.
