I was really intrigued by Bloom, but when I did a little digging, I realized that the only thing revolutionary about them was they hype. At best, their tech is an evolutionary improvement over other fuel cells. Other fuel suppliers are targeting the same applications with similar efficiencies and price-points. Furthermore, as others have pointed out, the claimed efficiencies assume full use can be made from the waste heat, and their overall efficiency is less than a gas turbine plant. Their overall capital efficiency may be lower still since. And to those waving hands about the expense of maintaining the electrical grid, get real. Big stream power plants are much more energy (and capital) efficient than these fuel cells, or gas turbine plants. It may that the efficiency of these things go up and the costs come down enough as volumes increase that the economics shift, but for now, providing base load through the grid via high efficiency power plants is going to be cheaper than why Bloom or their less hyped competitors offer. I think the real appeal of these things is that they give big customers a hedge against more gaming of the markets by the electrical generation and transmission companies. I doubt any of them are eager to become completely dependent the natural gas producers and pipeline companies either.
