Bloom Energy is a company that develops, builds, installs solid oxide fuel cells in company buildings and sells electricity.[1] The company, which is one of 26 named a 2010 Tech Pioneer by the World Economic Forum,[2] was started in 2002 by CEO K.R. Sridhar.[1]

History

The company was originally Ion America and renamed to Bloom Energy in 2006.[3] Its current name was conceived by Sridhar's nine-year-old son because he believed jobs, lives, environment and children will bloom.[4]

In Oct 2001, Sridhar had a meeting with John Doerr from the large venture capital firm Kleiner Perkins.[5] Sridhar was asking for more than $100 million to start the company. Bloom Energy has received $400 million of start-up funding from venture capitalists, including Kleiner Perkins[6] and Vinod Khosla.[7] In 2008 the company had a loss of $85 million.[1]

There is no Bloom Energy sign on the company's building, and there is little information on the company's website. The CEO gave a media interview (to Fortune Magazine) for the first time in 2010, eight years after founding the company, because of pressure from his customers.[1] A few days later he allowed a journalist (Lesley Stahl of the CBS News program 60 Minutes) to see the factory for the first time.[8]

On Wed, Feb 24, 2010, the company held a press conference.[9] Guests on stage were Colin Powell, Michael Bloomberg (via video conference), Arnold Schwarzenegger, Larry Page, John Donahoe and James C. Kennedy among others.[10]

Products and services

Bloom Energy Server

The Bloom Energy Server's thin white ceramic plates (4" x 4")[11] are made by baking common beach sand, and each ceramic plate is coated with a "secret" green ink (anode) on one side and another secret black ink (cathode) on the other side.[6] According to the San Jose Mercury News, "Bloom's secret technology apparently lies in the proprietary green ink that act as the anode and the black ink that acts as the cathode." Wired reports that the secret ingredient may be yttria-stabilized zirconia based upon a 2006 patent filing (7,572,530) that was granted to Bloom in 2009.[12] To save money the Bloom Energy Server uses inexpensive metal alloy plates as an electrolyte between the two ceramic plates, instead of platinum.[6]

Sridhar says that a single cell (one metal alloy plate between the two ceramic layers) produces enough power for a light bulb (25w)[13] and 64 cells produce enough for a coffee shop.[14] The Bloom Energy Server can run on most hydrocarbon fuels such as ethanol, biodiesel, methane or natural gas.[15] Colin Powell, who is on the board of Bloom Energy,[14][16] was recently quoted as saying "I have seen the technology and it works".[14] A Guardian report on the story added, "But industry watchers say they remain unsure exactly how it works."[14]

Cost

The Bloom Energy Server[17] is a solid oxide fuel cell made by Bloom Energy that can use liquid or gaseous hydrocarbons, from fossil or bio sources to produce electricity on the site where it will be used.[18] The current cost of each hand-made 100kw Bloom Energy Server is $700,000–800,000. In the next stage, which will likely be mass production of home-sized units, Sridhar hopes to bring down the cost of each of home sized Bloom servers to under $3000.[6]

Bloom Energy is developing Power Purchase Agreements to sell the electricity produced by the boxes, rather than sell the boxes themselves, in order to address customers' fears about box maintenance, reliability and servicing costs.[8]

Installations

The company says that its first 100kw Bloom Energy Servers were shipped to Google in July 2008.[19] Four Bloom Servers to make up to 400 kW (kilowatts) were installed at Google headquarters in Mountain View, California, who were Bloom Energy's first customer.[8] The Google installation currently operates on natural gas, with plans underway to switch to methane.[3] Another installation is for five boxes[15] to make up to 500 kW at eBay headquarters in San Jose, California.[8] Bloom Energy states that their customers include Staples (300kw - Dec 2008),[20] Walmart (800kw - Jan 2010),[21] FedEx (500kw),[22] Coke and Bank of America.[23]

Portable units

Writing for a Wall Street Journal blog, Rebecca Smith and Jim Carlton speculated that portable Bloom Energy Servers could be of use to the armed forces.[24] Other applications could be remote villages in Africa or Asia, which either do not have 24x7 electricity or currently use expensive diesel generators.[24] Sridhar plans to install Bloom Energy Servers in third world nations.[25]

Feasibility

According to BBC tech blogger Maggie Shiels, Bloom Energy is "being very coy and playful about what it will reveal to the press".[26] She quotes Michael Kanellos of Greentech Media regarding the general scope and feasibility of Bloom Energy's plans: fuel cells are not new technology and in order to succeed in the marketplace the Bloom Energy Server would need to be cheaper than existing types of renewable energy.[26] If Bloom Energy can develop such a technology, Kanellos predicts that established energy firms such as General Electric would derive most of the profits due to greater ability to manufacture and market a product.[26] Jacob Grose, senior analyst at Lux Research told Fortune Magazine that he doubts Dr. Sridhar has come up with a way of making these ceramic fuel cells cheaply.[1]

Bloom Energy Server technology is based upon stacking small fuel cells which operate in concert.[3][11] Bloom Energy has made a technological advance by developing stacked fuel cells where individual plates expand and contract at the same rate at high temperatures.[11] Scott Samuelsen of the University of California, Irvine National Fuel Cell Research Center questions how long the reliable operational life Bloom Servers will be. "At this point, Bloom has excellent potential, but they have yet to demonstrate that they've met the bars of reliability."[3] Lawrence Berkeley National Laboratory expert Michael Tucker told the San Jose Mercury News, "Because they operate at high temperatures, they can accept other fuels like natural gas and methane, and that's an enormous advantage... The disadvantage is that they can shatter as they are heating or cooling."[3]

John Doerr, who is one of the major venture capitalists of the company, asserts that the Bloom Energy Server is cheaper and cleaner than the grid.[15][27] An expert at Gerson Lehrman Group, wrote that, given today's electricity transmission losses of about 7% and utility size gas fired power stations efficiency of 26-48%, the Bloom Energy Server is up to twice as efficient as a gas fired power station, but no less efficient than one. [28] In a followup story entitled "Bloom Box: Segway or savior?" Fortune noted on 24 February 2010 that "Bloom has still not released numbers about how much the Bloom Box costs to operate per kilowatt hour" and estimates that natural gas rather than bio-gas will be the primary source of fuel for Bloom Energy Servers.[29]

Also on 24 February 2010, Sridhar told Todd Woody of the The New York Times that his devices are making electricity for 8–10 cents/kwh using natural gas, which is cheaper than today's electricity prices in some parts of the United States, such as California.[30][31] He also said the boxes will have a 10 year life span.[31] The CEO of eBay says Bloom Energy Servers have saved the company $100,000 in electricity bills since they were installed in mid-2009,[6] yet Paul Keegan of Fortune calls that figure "meaningless without the details to see how he got there."[29]

Competition

A Gerson Lehrman Group analyst wrote that GE dismantled its fuel cell group five years ago and Siemens have almost dismantled theirs.[32] United Technologies is the only large conglomerate that has fuel cell technology that could compete with Bloom Energy.[32] Toshiba only has technology to provide energy for a small device, not a neighborhood.[32]

Katie Fehrenbacher of Business Week reports that Sprint Nextel owns 15 patents on hydrogen fuel cells and is using 250 fuel cells to provide backup power for its operations.[33] Sprint has been using fuel cell power since 2005.[33] Last year Sprint's fuel cell program received a grant of over $7 million from the United States Department of Energy.[33] The Sprint program has partnered with ReliOn and Altergy for fuel cell manufacture, and with Air Products as a hydrogen supplier.[33] Business Week that a German fuel cell firm called P21, which is based in Munich, has been working on similar projects to supply backup power for cellular operations.[33]

In October 2009 the Department of Energy awarded nearly $25 million in grants for research and development of solar fuels, which Michael Kannelos notes in Wired may be similar technology to the solar cells in Sridhar's description of the Bloom Energy Server.[12][34] Department of Energy grant recipients included a variety of startup companies and universities.[34]
