@mos. I thought you were better than that putting steorn and this bloom box in the same paragraph. Shame on you for making a ridiculous comparison to make your point.

At least the Bloom Box doesn't seem pathetic as the Segway, with all of its hype.

Maybe Segway's powered by mini-Bloom Boxes will be the future of transportation!

The Economics of Bloom Energy's 'Breakthrough' Fuel Cell

$this->bbcode_second_pass_quote('', 'I')t appears that the unsubsidized price of the Bloom Box is about $7-8,000/kW, so their 100 kW units cost $700,000-800,000 without subsidy. As a fuel cell, it also needs fuel to run, in this case natural gas or another source of methane (such as landfill gas or biogas from anaerobic digesters).

After federal subsidies for fuel cells (they can claim the same 30% investment tax credit that solar gets) and a $2,500 California rebate, and assuming $7/mmBTU price for natural gas, a 100 kW Bloom Box unit generates electricity at 8-10 cents/kWh. That compares favorable to commercial electricity rates in many parts of the country,(the average is about 11 cents/kWh across the U.S., with higher rates in several states, including California, New York and Hawaii) so there could be a good market for the Bloom Box in distributed generation applications in a variety of places, assuming federal/state subsidies holds out.

[Windmills]

Interesting, but perhaps I need someone to explain why a different way to burn the same old stuff is revolutionary, at least in terms of energy security or sustainability. Maybe the efficiencies will allow us to postpone our problems or pawn them off on the next generation as we like to do.

I can see third world or developing countries getting excited about it. Assuming the units ever are able to ween themselves off welfare, which could be assuming a lot, these fuel cells could be similar to what cell phones are to telecommunications. You could leap-frog the need for a massive electrical infrastructure by being able to install any sized power wherever you need it, when you need it.

As a result, we'd have even more global competition as more areas of the world were energized and the global wage gradient would get even flatter. Bad news for the people at the top of that gradient. We'd continue to see more businesses flee to areas of cheaper labor as fuel cells open the up for business.

Impress me cornies, with something that is impressive. Like fusion power at $0.01/kwh or zero point energy.

What we mostly got now after more than a century of "progress" is endless variations of burning remnants of decayed plants in various putt-putt machines that fart out CO2.

A comment from Mercy Vestal at Ecogeek.org:

"According to Forbes, the actual cost is not $700K or $800K, but more like $900K or a cool million. In addition, from another NYT article the cells only last for THREE YEARS.

That's right, the system has a 10-year lifecycle but the fuel cells will need to be replaced twice. So who pays for that?"

As more details leak out, the more I'm agreeing with Mercy here. They're just trying to raise as much hype as they can so they can get another $400 million from the IPO to keep funding their R&D.

[SeaGypsy]

If it's true the cells only last for 3 years, that's a shame but doesn't kill the concept, as the cells seem to be quite cheap to manufacture and are likely to be able to be recycleable. I would gues the EROEI would be pretty good on this. The other factor of price; it makes perfect sense that these 1st units cost a fortune, there needs to be some return to investors who have so far been very patient in the R&D phase of the project. I would guess that if these gizmos take off they will come down massively in price over say 10 years. There is also the unremote possibility the patent could be sold to a mass manufacturer in China, this could accellerate price drops reverse exponentially. However, the USA desperately needs to hang on to such technologies if possible. How likely is this if the Bloom Box is all it's hyped to be?

[cephalotus]

What a hype about a typical 50% methane fuel cell at a cost of 7000US$/W!

For comparison:

Siemens is able to build GuD gas (=methane) power plants with an efficiency >60% at a fraction of that costs with an already proven and long lasting technology.

http://www.power-technology.com/projects/irsching/

The Siemens GuD is about 8.000 times more powerful, so it is able to "balance" a few hundred large wind turbines: This is exactly what we need in the future and not some super expensive small power plants at home that turn precious fossil fuel needed to balance renewable energies into another fluctuating electricity source.

Why is Bloom Energy Lying to Us?

$this->bbcode_second_pass_quote('', 'D')on't get me wrong, I'm extremely excited about Bloom Energy. I honestly think that their technology is a good thing for the world and that it might very well revolutionize the power infrastructure in America and throughout the world. And yes, it will create jobs and make a select few people very rich.

In fact, I think it's so revolutionary that it doesn't need to be inflated by false or misleading claims...which is why I'm a little put off by a few naughty little lies in the Bloom press release I got this morning.

Annoying press point #1: The Bloom Box "energy server" works with "nearly any fuel source." To me, "nearly any fuel source" means anything containing carbon/hydrogen compounds, ranging from gasoline to wood. The Bloom Box doesn't run on "nearly any fuel source" it runs on methane or methane or methane. That methane can be pumped out of the ground or captured from landfills, but it's still methane, and as I count it, that's one fuel source.

Annoying press point #2: Companies using the Bloom Box can "expect a three to five year payback on their capital investment." This is insane. The average cost per kW/h in California is 14 cents and Bloom promises a cost of roughly 9 cents. 100 kW multiplied by 8760 hours in a year times $0.05 per kW means 100 kW of continual electricity consumption over the course of the year will save a company a maximum of $45,000 per year. Call me crazy, but I don't see how they're going to pay for a $700,000 piece of equipment (even with a 50% government subsidy that won't last forever) over the course of three or five years by saving $45k per year.

Annoying press point #3: Probably what annoys me most about Bloom's press release is that they claim the box "provides a cleaner, more reliable, and more affordable alternative to both today’s electric grid as well as traditional renewable energy sources." Again, if it's not an outright lie, it's at least very misleading. The Bloom Box might be more reliable than both, but it isn't cheaper than the grid and it isn't cleaner than solar or wind. Marketing double-speak isn't good for anyone. If you take that sentence at face value, then you might as well cease all development of solar and wind and put 100% of the country's resources into Bloom Boxes.

Bloom Energy's technology is fantastic and exciting. It's much cleaner than our current electricity infrastructure and more practical than distributed solar. It's great, but there's no reason to make false claims when your product is this revolutionary.

Fuel Cell Maker Bloom Energy Opens the Kimono

$this->bbcode_second_pass_quote('', 'B')loom Energy, a fuel cell company that aims to help homes and businesses generate their own electricity from hydrogen and oxygen, publicly unveiled its technology and an impressive list of major customers at a Feb. 24 press conference attended by California governor Arnold Schwarzenegger and former U.S. Secretary of State General Colin Powell.

The Sunnyvale (Calif.) company, which was named a World Economic Forum Technology Pioneer in December, was in the headlines again this week after being featured on CBS News’ 60 Minutes on Feb. 21. It turns out that Bloom Energy has already signed up customers including Google, Coca-Cola, eBay, Wal-Mart, Staples, Bank of America, Cox Enterprises, and Fedex Express, a unit FedEx—further fueling excitement about the startup.

Privately-held Bloom Energy has already gained significant momentum: The company says it has raised “hundreds of millions of dollars” in venture capital from the likes of venerable Silicon Valley firm Kleiner, Perkins, Caulfield & Byers. Board members include Powell; Eddy Zervigon, a managing director at Morgan Stanley; and T.J. Rodgers, the chairman of solar cell maker SunPower. And some of America’s biggest companies are installing Bloom’s modular power-plant-in-a-box system, attracted by the promise of being able to efficiently generate their own electricity on site while reducing their carbon footprint, lowering energy costs, and mitigating the risk of power outages.

That said, he acknowledges it will take at least three to five years before Bloom boxes reach "grid parity" for home use, or price competitiveness with traditional residential-scale electric supplies.
