Wall Street Journal Names Top In Cleantech

The Wall Street Journal recently announced their Top 10 choices for clean technology companies based on data from Dow Jones VentureSource. The companies were evaluated on a range of areas, including capital, executive experience, and investor knowledge, suggesting all are need in order to succeed in the emerging green market.

The Dow Jones VentureSource data tracked around 500 venture-backed businesses in the United States and calculated the rankings by financial criteria, specifically the previous success of investors who sit on the board of the companies, the total amount of capital raised in the last three years, and track record of the founders of the companies, and the amount of growth the companies have seen in the last year.

Based on the evaluation system above, The Wall Street Journal chose the following companies as their Top 10 in clean technology ventures:

  1. Recycle Rewards Inc. – Based in New York City, the company sets up recycling programs at public schools and businesses where children collect used printer parts and cellphones in order to raise money. Prices range anywhere from $0.20 for a recycled ink cartridge to $60.00 for a 16GB iPhone 3GS. The idea is somewhat similar to a previous start-up we covered called ecoATM.
  2. Suniva Inc. – Based in Atlanta, the company specializes in mono-crystalline silicon solar cells, that claim a 19% energy efficiency rate, and the modules in which they are used. The vast majority of the company’s business is in Europe and Asia.
  3. eSolar Inc. – Based in Pasadena, the company builds large-scale concentrated solar power plants like the 20 acre, 5 MW Sierra SunTower, seen in the photo above, which sells energy to Southern California Edison. Last year, the company received a $10.8 million fund from the Department of Energy.
  4. MiaSolé – Based in Santa Clara, California, the company constructs thin-film Copper Indium Gallium Selenide (CIGS) solar panels that claim a 15.7% energy efficiency per square meter.
  5. OPOWER Inc. – Based in Arlington, Virginia, the company works in the smart grid sector, operating online costumer service software, data management, and utility reporting.
  6. GreatPoint Energy Inc. – Based in Cambridge, Massachusetts, the company specializes in hydromethanation, the process in which material like coal, petroleum coke and biomass are introduced to a catalyst, and then produce high-purity methane gas, of which CO2 can be sequestered.
  7. SeaMicro Inc. – Based in Santa Clara, California, the company makes high-performance 64-bit, energy efficient volume servers using standard and solid state disks.
  8. Boston Power Inc. – Based in Massachusetts, the company mass produces a range of lithium-ion batteries.
  9. Luxim Corp. – Based in Sunnyvale, California, the company manufactures small, super-efficient, solid state light emitting plasma products.
  10. Sapphire Energy Inc. – Based in San Diego, California, the company conducts research into green crude, an algae-based system that turns sunlight and CO2 into a biofuel. The company recently signed a multi-year agreement with the Monsanto Corporation.

The list represents applications for several industries, however, which will prosper remains to be seen. Deputing Managing Editor of The Wall Street Journal Alan Murray stated, “Many of these companies may ultimately fail – that’s the nature of the venture business. But we think at least one has a chance of making it big.”

    So Miasole’s PV modules are 15.7% efficient per square meter. I wonder what their efficiency is per square foot. (Who edits these things?)
