The Mystery of Bloom Energy


EDITOR'S NOTE: This article is www.karlbarth.nl from 2006. To see our take on Bloom Energy from a 2010 perspective, check out our new article
Bloom Energy: Should you Believe the www.tedxamsterdamed.nl Hype?
bloomenergy
Since hearing that John Doerr and brand viagra 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 televideocom.com 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 tramadol cash on delivery 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 generic viagra for sale wild speculation, I will ask: If these units have such wonderful energy densities and efficiencies, could we put one in a car?

Bloom Energy'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.

I just finished watching the Charlie Rose special showcasing Bloom Energy. As expected, K.R. didn't promote this company but provided very good insight on http://panaceahealthsolutions.com/viagra-prescription-label our dependency on oil. I am very glad to see Venture Capitalists investing in these kinds of companies as I believe the more research and innovation is done in this area, there will be more adoption.

In everything I've read so far about Bloom, they haven't said how efficient their fuel cell is. And be careful about claims of 70 % or 80 % which include cogeneration of www.peseta.org heat--that's fine if you really have a good use for the heat. If not, then you cannot turn the wow it's great how does levitra work extra heat into some form of energy with any reasonable efficiency--the temperature difference is far too small.

The real show-stopper for hydrogen, and fuel cells, is the round-trip energy efficiency. Batteries and supercapacitors are much more efficient, and I just don't see that gap closing. The other problems may be solvable, but I just don't see a way around the efficiency deficit. And I have the feeling I'm probably being a lot more kind to the technology than it deserves.

Reminds me of Medis. Nasdaq MDTL. Same level of super secrecy, no mention of energy balances, price reality checks, etc. Just that it was going to revolutionize the portable power landscape. Final product was nothing spectacular. Doubt if they are still in business, but were able to raise and blow "hundreds of millions" too. Then there was MTI Micro. Final test is always the customer.

Blooms box!
written by Ray, February 22, 2010
For the most part I can see the inaccurate thinking of those of you who seem to think yourselves to be something, when in reality, your not. One man here said that we are behind the times, our kids sit in front of the boob tube and achieve nothing, or play games that lead to there furthering stupidity, and not to mention our shelving of tech. that would have kept us from disaster, alas....we have corp. america who did the shelving to further there own pocket lining, surley whatever would have helped the official canadian pharmacy consumer must have been so evil that corp. america saw there bottom lines disapearing, and God forbid that happening. As far as I am concerned, I hope that this box, as its called, will be sold here in the good ole U.S., will have such an impact on the consumers life, and have an even bigger impact on those who called themselves corp. america to the point of "corp america" getting the point that we the consumer control the flow of dollars, not the other way around. And last but not the least, if your seem yourself to www.asian-americans.com be as smart as you think you are, next time you pay your electric bill....remember who your hard earned dollars are going to, it came from your toil and was demanded by the utility companies who will for sure go to the Gov. and demand to raise your bill once again to pay for there laziness in not getting to us before Bloom did. I hope this man is highly sucessful in his venture with this little box!

The technology sounds interesting and appears they have operational product in the field. However, to me, Mr. Sridhar comes off as a charlatan. Seems like there's always a story of the "eureka moment". In this case he turned the process around from creating oxygen to using oxygen (and fuel of course) to make electricity... Genius! Also, he is being disingenuous when he says it can run on solar. Perhaps solar could be used to make hydrogen then the hydrogen coud be used in the fuel cell, but fuel cells don't run on solar.

Cc: John Doerr
Subject: 60 Minutes on "Bloom Box"

Leslie Stahl's interview of John Doerr & the head of the Bloom Box company here in Silicon Valley illustrates one of our main problems in dealing with our environmental problems -- lax media.

It takes how long to hear the words "fuel cell" in your long interview? It takes how long to hear that "fuel" like gas goes into those "magical" Bloom cells? It does actually take less long to hear "oxygen" as an input.

But what does that oxygen & gas combination do besides generate some electricity? Where did Leslie, or Doerr, or the CEO, mention emission of carbon dioxide & water vapor? Both are greenhouse gasses. Bloom boxes are perhaps more efficient than the ~30% of a typical combustion power plant, but they too produce GHGs and are not at all "carbon neutral". And, we can't do with just "carbon neutral". Surely you've read... http://www.copenhagendiagnosis.org/ (p53 is good).

If you wanted to serve your audience, you would have started there. Then it would have been clear why there will not be a Bloom Box in everyone's yard, even if it does end up saying GE on it.

As a long-time CBS viewer, I'm disappointed in your lack of preliminary research, so useful questions would be asked & answered or evaded. Kleiner Perkins is in the business of making $. Bloom is in the business of getting $ to try to get enough going to sell the company to make $. Do you not know that about our valley?

Boy O boy!
Some real sour grapes on this new product.
The man is an educated engineer and is self motivated. Boo-hoo! He could have done this in any country but chose to do it here. Maybe not the only solution with fuel cells, but a good one nevertheless.

I hope he gets the Nobel Peace Prize.

It would take some smart marketing with new technology to challenge the grid and provide independence. It is happening. Looks like the right connections in D.C . have been made and this new box is not just a fad. It has some good backing and support to do what was inevitable in electrical demands and environmental considerations. It was bound to happen and the time is right.

I find the timing of the President and Bill Gates’ call for more nuclear plants an interesting thing: offer what people do not want and then offer what you want them to want. Does anybody really think either of those two did not know about this new rocket science? This thing is for real and will change the quality of life for everyone earth-bound. More nukes just did not sound like they filled a need smartly, but new designs are smarter, more efficient and can run on spent rod radiation; another way to clean up our radioactive act. We can make the bad stuff go away, and new nukes ARE truely green.

The grid will not go away over night and a consumer product will be secondary to industrial/commercial installation demands. Oversupply of power can spill back on to the grid and buffer demands. Now where is the competition in this picture? Who’s got a better solution? Time to pony-up and get that pig to market!

As for carbon emissions, consider the line loss of transmitted electricity that is pure waste. Don’t forget to include that inefficient resistive waste in the big picture of carbon emissions formulas. A shorter haul to the load from a generator is a factor of efficiency most do not consider. Not one minor or mega-watt plant out there can get around line loss. In fact, no present transmission line can avoid that loss. The poor efficiency of the grid transmission has not been solved. Localized power plants near the load are smart energy and are far less impacting on the environment, the eyeball and the bottom line.

Hooray for the Man who dared to change the world for the better!

Mr. G.E., tear down those ugly transmission lines!

Oh yea, G.E. moved some of their plants overseas. Any idea of how much product they make here?

And,… look at the time frame of the Enron monopoly crash and this emerging technology. Congress had a special meeting to allow that event. Chainey was pushing for 1200 gas fired power plants and we only got a few- some went belly up and were bought for pennies on the dollar- I worked on one of those and it sits dormant after completion. Bush was pushing for a national grid upgrade. The post election crash was attributed to Cisco having a bad quarter when the big three were in D.C. with their hats in their hands. Now how about an electric car?

Big energy money is backing this and has been taking profits along the way. Anyone who challenges the grid either goes away or goes ahead. Like it or not, this new technology has the Green light, and the green backs.

I loved the show but if the box is so low maintance and lasts 30 yrs how can a company make money after the initial purchase of these units . How long before you go out of business because your too good? ( a tire company that makes a tire last 30yrs will have to eventually fire alot of employees). Is the basic problem with providing new renewable methods of energy generation (that eventually you can't charge for it because) it's abundance and reliability drives the price down too low?

Just a thought... It seems to me that if this box can do everything they say, and it puts of less imissions... that because of it's size it could eventually end up in automobiles. If put into a vehicle with a storage cell in it then those vehicles could then be plug back up to the grid when not being driven and actually pay the consumer.

Another great device, but keep the advantages in perspective...
written by Candres, February 22, 2010
What Bloom Energy appears to do is to improve the efficiency and reliability of local electricity generation to a point that economically competes with centralized power plants. Instead of using fuel to make steam to turn the turbine in power plant generators, this process uses heat to cause a chemical reaction that results in electricity. The heat can be created by multiple means -- burning natural gas, oil, wood, nuclear decay, etc.

But if you are generating energy for local consumption, you no longer lose energy during transmission over power lines. This could be an efficiency win. However, if significant numbers of homes move off the grid, the relatively fixed transmission cost overhead will be shared (and rise) for the fewer grid-tied users.

Bloomboxes are not carbon-neutral, but better efficiency means less fuel is burned. From a carbon-neutral perspective, a nuclear power plant would be much better than a power-equivalent number of Bloomboxes. A concentrated solar generator using computerized mirrors is another centralized power plant that is carbon neutral, but too large and expensive for home use.

From an energy-independent and local energy cost viewpoint, Bloomboxes will be helpful. However, without a system to tax carbon-creating fuels, encouraging the use of carbon-neutral energy generation, we should not expect Bloomboxes to lower our national carbon footprint, even as it increases energy independence and reduces power line inefficiencies.

If it sounds too good too be true then...
written by David Artz, February 22, 2010
I'm American born electrical engineer (23 years and counting). While my expertise is not in the area of fuel cells I have enough of a basic understanding to know that what I heard from my elders applies here. That is, "If something sounds too good to be true, it probably is" Or, "there's no such thing as a free lunch"

In short, I think this is a bunch of hype intended to drive up the company value so investors and CEO KR Sridhar make lots of money fast. You don't think greed is limited to financial institutions do you?

Oh, and while my kids enjoy sitting in front of the TV playing video games, that only is allowed when their home work is completed. My oldest is a A student at UT pursuing a Biology degree, my next youngest will graduate from high school next year in the top of his class I am sure (he's all GT/AP advanced classes for many years now) - he wants to pursue something in Chemistry. And my daughter of 15 has NO grades less then a 98 in any of her course work for several years now. She wants to pursue something at colleges with respect to brain science and medicine (they lost their mom several years ago to mental health problems). So, my kids are at least 8th generation Americans. There is still hope in this country for "growing our own" engineers, scientists, and doctors.smilies/angry.gif

Bloom Energy technology is slightly diffrent from existing patents in the field of oxi fuel cells. The viability of this technology depends upon mass production at affordable cost without product failure rate less than 1% and without some serious maintenace costs over the next 10 years for such boxes. I think, SRIDHAR + DOER formula might be the answer of success of this projcet. Capital behind this project and market size being so huge, make Bloom Energy Box a possible win-win for both enduser as well as investors.


Now they are out in open, pressure will be on the production and marketing the box at reasonable cost which provides the pay back of investment in less than 5 years or so.
Good luck MR Sridhar and John Doer.

Finally a large step forward for humans
written by Seren, February 22, 2010
This is a major step towards empowering the individual, rather than the (often)corrupt corporations and governments of the world.
It remains to be seen if the 15% that control and manipulate the media, newspapers, military energy and industrial complexes will allow it to proceed. They profit only by continually promoting violence, chaos, and 'secret operations' that weaken peaceful governments around the world. The last thing they want is for the individual to be empowered in any way, or for the world to not have to fight each other decade after decade for energy! OMG what an evolved concept.
I will wager that Advanced races are looking at this step in human evolution closely, to see if they have evolved enough to actually grasp the concept of sharing.
What humans spend in violent/weapons/protection endeavors for one day, could be used to feed, clothe, educate and house the entire planet for a year! Its so sad but perhaps there is a glimmer of hope even for the ultra violent race known as Humans ?

The world could change very quickly if the bloom box comes to be. It is hard to believe big power companies would allow this to get off the ground. This would probably put a quick stop to solar and wind electric generation. There are solar companies being built right now that I believe would quickly stop production. I would want one in my back yard but I also wanted to start a solar/wind electric company that I believe would quickly fail due to this technology if it is real. Why buy expensive solar and wind that takes up a huge amount of space when this technology would take up so little space an anyone's yard. Tim Drake

Hearing about this technology gave me a slight fear of other technologies that may not try to advance due to cheap energy. Technologies that are trying to make devices more effiecient to use less power. I am constantly trying to think of simple ways myself to save money on my electric bill. I burn wood for heat, use the wood furnace to preheat my water before the electric water heater, trying to resize the elements in my existing heater and using a timer to shut off the water heater. All to reduce my electric bill. If I was not doing this, I would have more time to be with my family, could have more money to buy them computers of their own so they could be able to study and keep up with the rest of the world. This could help the economy due to money being spent on other items instead of high electric bills. I would probably heat with electric instead of wood and back up fuel oil. That should reduce the carbon foot print.

Without a heat balance the speculation about this device is just that. It is amazing that such hype can be generated about this product without any heat balance whatsoever, perhaps indicative of intellectual malaise rather than expertise of Bloom.

It is all about energy return on energy invested...
written by Tim Wessels, February 23, 2010
Fuel cell technology has been around for decades. Bloom Energy has possibly advanced the technology in ways that will make it more practical to use fuel cells for on-site electrical power generation.

Since electricity can be generated from wind, solar, coal, water (hydro-electricity) natural gas and uranium sources, it will be interesting to find out how much energy must be "invested" in the Bloom Energy fuel cell process compared with the energy output from it over its useful lifetime. In other words, what will the net energy ratio of a Bloom Box turn out to be?

We will be facing electricity shortages in 10-20 years and the assumed alternative sources are low net energy yielders. Solar and wind must be collected and stored and will be small contributors of electricity due to siting requirements. Coal supplies will be peaking around 2025 and there are severe environmental and health problems surrounding its use. Ditto for uranium, which is also in short supply and still lacks an operating permanent storage facility for spent uranium fuel. Our two largest energy sources for electricity generation (coal and uranium) will need to be replaced by other energy sources otherwise electricity shortages will occur.

Will the Bloom Box be a solution? We will find out when the technology utilized in the process is revealed in more detail, and when the net energy calculations of a Bloom Box can be performed by reputable third-party analysts.

Propane

I'm building a house and just now choosing the boiler for radiant heat. I will hold up to six months if this fuel cell can run off propane. I don't have an option for natural gas.

Limited efficiency boost
written by Sandy, February 24, 2010
It doesn't matter what is going on inside the box. Conservation of energy and high school physics and chemistry dictate its efficiency limits. For example, the Bloom box can't be a whole lot more efficient than CHP (combined heat and power) plants. At the very best the Bloom box can provide a small double-digit percentage improvement over a CHP plant, or less. And if you want just heat, my multistage gas furnace is about 98% efficient. The Bloom box can't beat that, regardless of what it does inside. No matter how "clever" you are, you can't produce more energy than there is in the difference between the chemical bonds in methane and the resulting water and carbon dioxide.

unfortunately perfect for america
written by eric walsh, February 24, 2010
I laugh that you people are excited about something that might provide a bit of an efficiency gain for a number of large expenses.
Firstly purchasing those fuel cells and the network of fuel to run them, (or would we truck it directly to a large tank also on the lawn several times a year)
Secondly our grid is what makes us have a chance to make solar and wind energies work. It is not robust enough right now to allow those green energies to handle 20% of the load. But as we dismantle the grid we lower that value.
Please do not vote for this initiative with your time or money, the tipping point for wind and solar (thermal) energies is so close at hand.

This is a elaborate master plan to exploit money and as such the management as well as VC firm which is also ties up with Google now try to take materials out of the internet which is against this bloom energy and its predecessor ion America

Will this change the world?
written by magnum, February 25, 2010
It was said that the device could be installed in homes, generating both electricity and heat, which would result in big efficiency gains. Commenters on Reddit point out that the real savings may lie in avoiding transmission and maintenance costs with a machine that’s much simpler to handle than a full fledged power plant. Although the boxes cost a lot (up to $800K), the amount of power they allegedly put out more than makes up for it.

Is this the future? http://bit.ly/bloom-energy-will-change-the-world

The Fuel Cell Energy of Danbury, CT Molten Carbonate fuel cell and Versa Power Systems of Littleton, CO Solid Oxide fuel cell appear to be far ahead of Bloom. Bloom also has a Solid Oxide fuel cell.

FCE targets loads from 300 kW to 3,000 kW. FCE has already cut its costs so that its largest model can now be manufactured so as to sell margin positive. It currently has 60 installations around the world. FCE owns 42% of Versa Power Systems. Versa Power does not yet market a commercial product but has already got the cost of its smaller fuel cell down to $700 per kW, participating in the billion dollar SECA cost reduction program. It expects its fuel cells to cost only $400 per kW in two years. Bloom claims its fuel cells will be commercial in about 10 years.

Neither FCE nor Versa use platinum catalysts and neither need to be fueled with hydrogen. These are advantages that Bloom implies are exclusive to its product. Most American houses have a peak load of 10 kW. The Versa Power Solid Oxide fuel cell is suitable for that use but can also be scaled up to 100,000 kW plants.

Bloom's 100 kW fuel cell weighs 100 tons according to its spec sheet. That is 2,000 lbs per kW. But the Versa Power fuel cell weighs only 200 lbs per kW, an order of magnitude lower. Versa Power has been cooperating with the US Airforce on developing power supply for military drones and with the US Navy on developing power supply for mobile underwater platforms. At 2,000 lbs per kW, Bloom fuel cells are far too heavy for this purpose.

FCE's stationary fuel cell has an efficiency of 47% after its DC output (efficiency 54%) undergoes losses due to its conversion to AC. Its efficiency in small sizes permits it to be located near its loads so it does not have to provide for losses over transmission and distribution lines. Conventional coal fired steam turbine generation must get up to sizes of some 500,000 to 600,000 kW to reach an efficiency of 38% (or 43% for supercritical units). Power from these giant units when adjusted for transmission line and distribution line losses to the customer's meter, may only have an efficiency of 29%.

FCE can also be used as a combined cycle or hybrid. When its exhaust is fed into a turbine, its electrical efficieny increases to 56%. It can be used at gas transmission pressure step down stations where it can develop efficiency of 60%. It claims that much larger units of 40,000 kW can achieve an electrical efficiency of 78%

It can also cogenerate because the units is on site, the heat will only have to travel a few yards. Heat energy can't travel for long distances. When there is a need for domestic hot water, space heating or air conditioning at the site of the electrical load, the fuel efficiencly can grow as high as 90%+ as it has at one installation in Germany.

FCE has partnered with POSCO Steel Co. of South Korea. It is one of its best customers. POSCO has built a factory to manufacture the mechanical and electrical portions of FCE's fuel cell leaving the stack elements to fCE. FCE is currently manufacturing at a rate of 30,000 kW per year and will be raising its capacity to 50,000 kW per year.

The value of Bloom Energy Servers beyond GHG reduction
written by Powell, March 07, 2010
There are many benefits to Bloom's solid oxide fuel cell technology if it succeeds. The distributed nature of the device could help foster adoption of electric vehicles since it could help offload some of the stress on the national grid.

www.notpetroleum.com/2010/02/27/bloom-energy-and-the-electric-car/

Bloom's energy server can also help reduce the amount of fresh water used to generate electricity at centralized coal-fired plants especially for arid climates such as in the southwestern US.

www.drywelljournal.com/2010/03/06/bloom-energy-and-water-conservation/

I think it is important that we look at the big picture of the value of technologies such as this instead of just focusing on whether its claims of GHG reduction are accurate.

NOT THE SOLUTION, SORRY, GOOD TRY
written by Engineer, March 12, 2010
Wake up! This thing runs primarily on 15psi natural gason a massive scale(a NON RENEWABLE RESOURCE).
15PSI natural gas requires a special service from a natural gas network.
It chugs NG. Your just moving from one grid to the other. The BOX is HUGE and cost more than Solar or Wind technologies. The Engineer holds up a small stack in his hand but when it is installed in the BOX it is as big as a pickup truck for just 25kw. Had to laugh when Colin Powell said it could power a village in Africa...and you will be powering it with what fuel in that small village???? Its a natural gas generator, not an "E" solution period.

Promising... how about biogas as the fuel source?
written by GreenMan, March 15, 2010
Here in the Smoky Mountains we still have small cow farms, for diary and/or meat production, and small scale feedlots. Needless to say, we get knee deep in cow manure while profitability is continuously decreasing. Sure would be nice if we could convert cow manure into biogas continuously, and then feed the biogas into a BloomBox to generate electric power and heat. Anybody out there working on that? Anybody want to work on that? Meet me at www.greenequitybuilders.org

The Bloom Box has to be powered by some fossil fuel.
If diamonds are infused with liquid O2 they will burn at 1500 degrees approximatly. Producing a co2 base, capturing and storing the intense heat would necessitate
enduring that heat to heat the water to for hydrogen.

A c.e.o fm India
written by Osai Chella, June 17, 2010
We were known as snakecharmers in the west. Thanks to the western media which acted like a heritage tourism promoter! Now they wake up and looking at the east for all their problems, material and spiritual. IF YOU LOOK BACK INTO THE HISTORY say 2000 yrs ago, no country was invaded like INDIA by so many outside forces... Alexander to British, Dutch,French, Portuguese ! So when westerners were Gypsies Indians and Chinese were great inventors. Only thing they didnt mastered like west is EXPLOITING OTHER RACES (of Africa and Asia). Now the wheel has turned 180 Degree !
