CENTENNIAL, Colorado (January 3, 2011) — Ciris Energy, Inc. ("Ciris"), an emerging natural gas production company whose proprietary technology biochemically converts coal to methane at large scale and low cost, has raised equity in its second round of financing, led by new investor Khosla Ventures. Existing investors Braemar Energy Ventures, Rho Ventures, and GE Energy Financial Services, a unit of GE (NYSE: GE), also participated in the funding. Financial details were not disclosed.

Lab and field test results show that Ciris' technologies are more economical than conventional and unconventional natural gas development and thermochemical gasification processes. The financing will allow Ciris to implement its first commercial-scale projects for in-situ biochemical conversion of coal to methane, and bring its ex-situ biochemical coal conversion technology to commercial-ready status.

"Ciris has the potential to transform and extend the coal resource base in a number of distinct geographies," said Vinod Khosla. "This may be the cleanest and cheapest form of clean coal."

Jerry Clark, CEO of Ciris Energy, commented, "Khosla Ventures is one of the leading investors in emerging energy technologies, and we are pleased they could lead our Series B and join our existing investors. In 2010, we achieved several key milestones on our road to commercialization, and 2011 promises to build on that as we implement our technology in commercial field development to produce clean, low-cost energy."
