Bloom Energy is the company that develops, builds, installs Bloom Energy Servers.[9] The company, started in 2002 by CEO K.R. Sridhar,[9] is one of 26 named a 2010 Tech Pioneer by the World Economic Forum.[10] [edit] History In October 2001, Sridhar had a meeting with John Doerr from the large venture capital firm Kleiner Perkins.[11] 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.[12] The company, originally called Ion America, was renamed to Bloom Energy in 2006.[13] Sridhar credited his nine-year-old son for the name, saying that his son believed jobs, lives, environment and children would bloom.[14] One of the celebrities appearing at the product launch was Michael R. Bloomberg, who appeared by video link.[15] Bloomberg's business news network covered the event, but was attributed every statement to "Bloom Energy".[16] 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.[9] 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.[17] On February 24, 2010, the company held its first press conference.[13] [edit] Costs [edit] Installation The current cost of each hand-made 100 kW 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 more than halve the cost of each of home sized Bloom servers to under $3000.[6] Bloom estimates the size of a home sized server as 1 kilowatt, although cNet News reports critical estimates recommend 5 kW capacity for a residence.[18] The capital costs according to NewsWeek magazine is $7–8 per watt. [2] [edit] Usage On 24 February 2010, Sridhar told Todd Woody of 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.[19][20] Twenty percent of the Bloom Energy Server cost savings depend upon avoiding transfer losses that result from energy grid use.[18] 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.[17] Fifteen percent of the power at eBay is created with Bloom technology; after tax incentives that paid half the cost eBay expects "a three-year payback period" for the remaining half, based on California's $0.14/kWh cost of commercial electricity.[21] [edit] Installations The company says that its first 100 kW Bloom Energy Servers were shipped to Google in July 2008.[22] Four such servers were installed at Google headquarters in Mountain View, California, who were Bloom Energy's first customer.[17] Another installation is for five boxes[1] to make up to 500 kW at eBay headquarters in San Jose, California.[17] Bloom Energy states that their customers include Staples (300 kW - December 2008),[23] Walmart (800 kW - January 2010),[24] FedEx (500 kW),[25] The Coca-Cola Company (500 kW)[26] and Bank of America (500 kW).[27][28] Each of these installations (current or planned) is located in California. Most use either biogas or solar energy inputs. [edit] Portable units Writing for a Wall Street Journal blog, Rebecca Smith and Jim Carlton speculated that portable Bloom Energy Servers could be used instead of traditional generators by the armed forces.[29] Sridhar plans to install Bloom Energy Servers in third world nations.[15] Ex-Chairman of the Joint Chiefs of Staff, Colin Powell, now a Bloom Energy board member, said the Bloom Energy generators could be useful to the military because they are lighter, more efficient, and generate less heat than what the military uses now.[30] [edit] Feasibility Bloom Energy According to BBC tech blogger Maggie Shiels, Bloom Energy is "being very coy and playful about what it will reveal to the press".[31] 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.[31] 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.[31] 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.[9] Bloom Energy Server technology is based upon stacking small fuel cells which operate in concert.[5][13] 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.[5] Scott Samuelsen of the University of California, Irvine National Fuel Cell Research Center questions how long the reliable operational life of 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."[13] 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."[13] John Doerr, a venture capitalists, who has a large investment in the company, asserts that the Bloom Energy Server is cheaper and cleaner than the grid.[1][32] 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.[2] 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.[33] Jonathan Fahey of Forbes comments: Are we really falling for this again? Every clean tech company on the planet says it can produce clean energy cheaply, yet not a single one can. Government subsidies or mandates keep the entire worldwide industry afloat... Hand it to Bloom, the company has managed to tap into the hype machine like no other clean tech company in memory."[34] [edit] Efficiency Current gas fired power stations convert chemical energy to thermal energy to mechanical energy to electrical energy. A modern combined cycle gas turbine power plant (CCGT) can reach 55-58% overall cycle efficiency. Sridhar says Bloom Boxes convert chemical energy to electrical energy in one step, and are more fuel efficient than current gas fired power stations and also reduce transmission/distribution losses by producing power where it is used.[35] Sridhar also said the boxes will have a 10 year life span.[20] 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."[33] [edit] Competition A Gerson Lehrman Group analyst wrote that GE dismantled its fuel cell group five years ago and Siemens have almost dismantled theirs.[2] United Technologies is the only large conglomerate that has fuel cell technology that could compete with Bloom Energy.[2] Toshiba only has technology to provide energy for a small device, not a neighborhood.[2] 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.[36] Sprint has been using fuel cell power since 2005.[36] Last year Sprint's fuel cell program received a grant of over $7 million from the United States Department of Energy.[36] The Sprint program has partnered with ReliOn and Altergy for fuel cell manufacture, and with Air Products as a hydrogen supplier.[36] Business Week reported 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.[36] United Technologies makes fuel cells costing $4,500 per kilowatt. 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.[7][37] Department of Energy grant recipients included a variety of startup companies and universities.[37] According to an article in NewScientist, there is a claim stating the Bloom Box is "electrolyte-supported" and based on that, there are at least two well-established companies, Topsoe Fuel Cell[3] and Ceres Power, already rolling out products with more advanced non-electrolyte-supported cells. Ceres having a four-year program to install 37,500 units in the homes of customers of the UK's British Gas[disambiguation needed]. [38] Ballard Power's comparably scaled products are based on proton exchange membrane fuel cells. Ballard's 150 kW units are intended for mobile applications such as municipal buses,[39] while their larger 1 MW stationary systems are configured from banks of 11 kW building blocks.[40] Another competitor that already has product in-market in Europe and Australia is Ceramic Fuel Cells [41], with an efficiency o
