Prudent Energy Has Been Named a 2010 Global Cleantech 100 Company

Washington, DC, USA – October 13, 2010

Prudent Energy, the world leader in VRB® Energy Storage Systems, today announced it has been named in the prestigious 2010 Global Cleantech 100, produced by the Cleantech Group, providers of leading global market research, events and advisory services for the cleantech industry. The list is produced as part of the Global Cleantech 100 program, run in collaboration with the Guardian News and Media and sponsored by Autodesk.

The Global Cleantech 100 is unique as it highlights the most promising private clean technology companies from all around the world, those companies which are the most likely to make the most significant market impact over the next 5-10 years. The Cleantech Group, draws on its own data and research, and combines it with the weighted qualitative judgments of both hundreds of cleantech industry insiders, and the viewpoints of a 60-strong, international expert panel. To qualify for the list, companies must be independent, for-profit, cleantech companies that are not listed on any major stock exchange.

4,616 nominations were received from 3,260 unique sources, giving a long list of 3,138 companies drawn from 50 countries. 218 companies were presented to the expert panel for final input. The end result was 100 companies from 14 countries.

The 60-strong expert panel is drawn from well-respected organisations in cleantech innovation from around the world, including leading investors such as Emerald Technology Ventures, Generation Investment Management, Kleiner Perkins Caulfield & Byers, New Enterprise Associates, SAM Private Equity, Sequoia Capital, and VantagePoint Venture Partners, and from a wide variety of corporations from many different industries, such as BASF, GE, Honeywell, IBM, Procter & Gamble, Siemens, and Veolia.

“This second Global Cleantech 100 shines a spotlight on which companies and which technology areas the global innovation community is currently most excited about, from a commercial standpoint,” said Richard Youngman, MD, Europe & VP, Global Research at Cleantech Group. ”There have been significant changes since 2009: more Asian companies and less renewable energy generation companies attest to the growing diversification of cleantech innovation. Cleantech is a broader phenomenon than just clean energy. The wider issues of resource scarcity are starting to gain attention and traction.”

“We are delighted that Prudent Energy has been recognized by such a distinguished panel of investors and executives,” said Jeff Pierson, Senior Vice President and head of Prudent’s Bethesda, Maryland office. “As a company with global presence, we see a tremendous opportunity for VRB® energy storage systems to become the technology of choice for power utilities and industrial customers, especially as they struggle with integrating renewable energy generation and managing the costs of upgrading the grid.”

The full list of Global Cleantech 100 firms is available online, on the websites of the Cleantech Group (http://cleantech.com/GlobalCleantech100.cfm). and the Guardian (http://www.guardian.co.uk/globalcleantech100).
