LOUISVILLE - Sundrop Fuels Inc., a New Mexico-based clean energy company, has entered the Boulder Valley market, but is keeping quiet on its new business.

The company signed a lease for 19,941 square feet of space at 1722 Boxelder St. at the Colorado Technology Center business park and is advertising jobs for the new location.

According to several venture capital Web sites, Sundrop is engineering a way to process carbon dioxide greenhouse gases with solar energy to create usable fuels and electricity. The technology comes from the former company Los Alamos Renewable Energy, which Sundrop and Solarec Inc. recently acquired.

"Our technology uses solar heat to drive chemical reactions, enabling the production of liquid fuels from clean and renewable resources," Sundrop wrote in one of its online job postings. The company said it is looking for chemical engineers to work at its new Colorado location in Louisville.

Palo Alto, Calif.-based Oak Investments Partners and Santa Fe, N.M.-based Sun Mountain Capital are at least two venture capital firms investing in the new company, according to their Web sites.

Sundrop is subleasing its new space in Louisville from Security With Advanced Technology. Arn Hayden and Andrew Freeman with Freeman Myre, and Paul Keilt with Jones Lang Lasalle helped broker the real estate deal.

Sundrop officials declined to comment for this report.
