Bloom Energy: Should you Believe the Hype?

The clean tech news of the week is going to be dominated by Bloom Energy's emergence from stealth.

I can hardly believe that it was almost four years ago that I first wrote about Bloom. Reading that 2006 EcoGeek article, I'm proud to say that we got the broad picture right, but the details are still tantalizing. Bloom Energy's current product is a relatively inexpensive and versatile fuel cell that can power roughly 100 American homes.

The devices cost $700,000 a piece an are roughly twice as efficient as natural gas power transmitted through the grid.

They've sold a bunch of these boxes (with hefty federal and state subsidies) to a bunch of large businesses in California, including Google, eBay, FedEx, WalMart and Staples.

The boxes are busy creating "clean" energy as we speak.

Bloom has finally opened the doors to its operation to the press, allowing 60 Minutes a walk-through of their facility as well as providing interviews with the CEO of eBay and former Secretary of State Colin Powell.

But I put "clean" in quotation marks because, despite the fact that the words "carbon dioxide" are never mentioned, Bloom Boxes still pump CO2 into the atmosphere, albeit far less than a traditional grid-scale natural gas plant would. Bloom is certainly cleaner energy, but while they're busy comparing themselves to solar power and wind, they're not true clean energy unless they use bio-gas. I applaud them for using bio-gas when they can, but there simply isn't enough of the stuff to power Bloom Boxes on a significant scale.

But let's not spend too much time arguing about whether "cleaner" counts as "clean." In my book, this is certainly good enough.

Bloom's true potential is in super-charging the distributed power system. Bloom (very optimistically) wants to shrink its box (in size and cost) so that every American can have one in their basement for around $3000.

The box would power the entire house, basically making a connection to the grid a convenience, not a necessity. This may not seem important until we realize that up to half of the power produced at a power plant is lost in transit.

Bloom's might also help power the developing world without expensive power infrastructure just as cell phones have created a cheap communications infrastructure.

Bloom's goals are lofty and it may be that distributed power is going to be a long time in coming if it comes at all, but while they're doing a great job of making this revelation sound more important than it is in the short term, the chance remains that this could actually be a very big deal.

Here is a story from - The Mystery of Bloom Energy

Another Article Written by Hank Green on 29/12/06:

Since hearing that John Doerr and the CEO of Bloom Energy are going to be appearing together on Charlie Rose, I've been putting some pieces together. First, KPCB, Doerr's venture capital firm, has been saying repeatedly, "we've been investing in some very interesting alternative energy opportunities."We know that they've funded Eestor, who makes the long-charge supercapacitors that will be powering the Zenn city travelers. But we also knew that that couldn't be all their investing in. KPCB is one of these multi-billion dollar venture capital firms, and they've been (very intelligently) focusing on clean technology recently.

After a bit of research, I'd like to offer some speculation about what Bloom Energy will be doing.

We already know about the technology the company is based on. In short, K. R. Sridhar created a kind of fuel cell that can combine water, oxygen and an energy source, like natural gas or ethanol, to produce power extremely efficiently.

My guess is that that the profitability of these devices lies in distributed power.

I think Bloom Energy is looking to install 100 Kilowatt power units in everyone's houses. These will be flex-fuel, but likely running mostly on natural gas. They will also probably produce heat, and cooling, as well as power, making the devices roughly 85% efficient (thus generating two times less greenhouse gas emissions than a power plant per unit of power used.)

I don't want to say that they will also be used to create hydrogen, but the technology allows for the fuel cell to easily produce hydrogen if 100% of it's power isn't needed. This could then be used to fill up your new Honda FCX. As a last piece of wild speculation, I will ask: If these units have such wonderful energy densities and efficiencies, could we put one in a car?

Bloom's current website says absolutely nothing about anything. But, it does finish up with a pretty picture of the earth and the tagline "Be the Solution," which lends credence to everyone having their own super-efficient little power plant in their basement.

I can't wait to hear what K.R. Sridhar has to say for himself tonight on Charlie Rose.
