The company was founded in 2003 as Quantum Leap Technology[5][6] after Brett Vinsant created the company's fuel cell in his garage in Hillsboro, Oregon.[7] In August 2005, Quantum Leap changed its name to ClearEdge Power.[6] In January 2006, they received a $2 million investment from a subsidiary of Applied Materials.[8] At that time the company built fuel cell systems to produce back-up power and for continuous power applications.[8] By May 2007, the company had grown to 20 employees and had raised $10 million in venture capital.[9] In early 2008, ClearEdge sold and installed its first fuel cell unit.[10]

ClearEdge received an additional $11 million in venture capital from Kohlberg Ventures LLC in January 2009.[11] On May 1, 2009, Russell Ford became the chief executive officer of the then 40-employee company,[12] with Slangerup joining the board of directors.[5]

The company expanded the 55,000-square-foot (5,100 m2) headquarters to 80,000 square feet (7,400 m2) in December 2009 after receiving an additional $15 million in venture capital from Kohlberg Ventures.[13] At that time the company had grown to 150 employees, and 95% of all capital raised came from Kohlberg Ventures.[5] ClearEdge raised a total of $29 million from Kohlberg in 2009 alone.[14] In November 2009, the company began to ship a five kilowatt fuel cell and had orders for 300 of the units by December 2009.[15][16] ClearEdge gained $11 million more in private financing in January 2010.[17][18]

In February 2010, a fuel cell was installed at a Hillsboro Fire Department station; local dignitaries included Congressman David Wu.[19] Wu’s district includes ClearEdge’s headquarters in Hillsboro, and Wu has sponsored several bills that would provide tax credits for fuel cell customers.[19][20][21] ClearEdge backed one of the bills, which would increase the federal tax credit for installing a fuel cell at a residence to be same as for businesses.[20][22] Neither of Wu’s bills has made it out of committee.

ClearEdge signed a $40 million deal in June 2010 to supply 800 fuel cells to Korean based LS Industrial Systems over a three-year period.[23][24] LS Industrial Systems would sell the ClearEdge5 units in Korea, which had recently required 10 percent of power on new construction come from renewable power.[25] This was the first large contract for the company outside of its core California market.[23] The company planned to build 1,000 units in 2010, and double that in 2011.[7] ClearEdge was awarded a $2.8 million federal Department of Energy grant that would allow them to provide 38 fuel cells to ten different organizations including a grocery store and community college.[26] They raised $73.5 million in private equity funding in August 2011 to help expand sales to Europe and South Korea.[2]

In December 2012, ClearEdge reached an agreement with United Technologies Corp. to buy its fuel cell business, UTC Power.[27] In February 2013, ClearEdge closed on its acquisition of UTC Power.[28] The next month, the company reduced its workforce by 39%, with many layoffs coming at the former UTC unit.[29] Later that month the company announced it had raised another $36 million in capital.[30] In 2013, the company relocated its headquarters to Sunnyvale, California.[31] The former UTC unit in Connecticut was then closed without warning in April 2014 as the company weighed filing for bankruptcy protection.[3]

In July 2014, ClearEdge was purchased by South Korean conglomerate Doosan Group for 32.4 million, plus debt.[32]


Doosan Fuel Cell's headquarters are in South Windsor, Connecticut. The main product is a four hundred kilowatt fuel cell.

The technology is based on silicon and operates at 320 °F (160 °C).[6][10]

The fuel cell is powered by natural gas which a membrane breaks down into water, heat, carbon dioxide (CO2), and hydrogen, with the latter passing through a second membrane where electricity is generated.[15] CO2 and water are the only waste produced. The micro combined heat and power fuel cell have approximately 85% total fuel efficiency.[10][15] PEM fuel systems have an electric efficiency of about 30% .[21]
