Our unique on-site power generation systems utilize an innovative new fuel cell technology with roots in NASA's Mars program.

Derived from a common sand-like powder, and leveraging breakthrough advances in materials science, our technology is able to produce clean, reliable, affordable power,... practically anywhere,... from a wide range of renewable or traditional fuels.

Our Energy Servers™ are among the most efficient energy generators on the planet; providing for significantly reduced electricity costs and dramatically lower greenhouse gas emissions.

By generating power on-site, where it is consumed, Bloom Energy offers increased electrical reliability and improved energy security, providing a clear path to energy independence.

Company History:

Bloom Energy can trace its roots to work performed at the University of Arizona as part of the NASA Mars space program. Dr. KR Sridhar and his team were charged with creating a technology that could sustain life on Mars. They built a device capable of producing air and fuel from electricity, and/or electricity from air and fuel.

They soon realized that their technology could have an even greater impact here on Earth.

In 2001, when their project ended, the team decided to continue their research and start a company. Originally called Ion America, Bloom Energy, was founded with the mission to make clean, reliable energy affordable for everyone on earth.

In 2002, John Doerr, and Kleiner Perkins became the first investors in the company. Kleiner Perkins was legendary for its early backing of other industry changing companies, like Google,, Netscape, and Genentech, but Bloom was its first clean tech investment. In fact, at that time, clean tech was not even really a word.

With financing in place, the team packed three U-hauls and headed to NASA Ames Research Center in Silicon Valley to set up shop. Over the next few years, the technology quickly developed from concept, to prototype, to product, as the major technological challenges were solved and the systems became more powerful, more efficient, more reliable, and more economical.

In early 2006 Bloom shipped its first 5kW field trial unit to the University of Tennessee, Chattanooga. After two years of successful field trials in Tennessee, California, and Alaska, to validate the technology, the first commercial (100kW) products were shipped to Google in July 2008.

Since that time Bloom's Energy Servers have helped our customers generate millions of kWhs of electricity and eliminate millions of pounds of CO2 from the environment.

From humble beginnings on Mars, Bloom Energy is now changing the Earth for the better.

Bloom Energy has received venture capital from Kleiner-Perkins, NEA, and Gentry Venture Partners.

Bloom Energy is one of the GoingGreen 2009 top 100 private companies.
