Ciris Energy develops bioconversion technologies that convert carbon in low‑rank coal into natural gas and industrial chemicals using proprietary in‑situ bioconversion (ISBC) and ex‑situ bioconversion (ESBC) processes. The company is operating a first‑phase commercial ISBC plant in the Powder River Basin of Wyoming and is targeting initiation of a demonstration ESBC plant in 2014. Its ISBC process rejuvenates unproductive coal territories by stimulating and optimizing naturally occurring processes, while ESBC converts mined coal into methane and chemicals. Ciris positions these technologies as cleaner, sustainable alternatives to traditional coal utilization and aims to harvest untapped energy resources. The company was founded in 2007 and is headquartered in Centennial, Colorado. Recent capital raises and partnerships are intended to advance commercialization and support international expansion, particularly into Asian markets. Ciris Energy develops biochemical technologies to convert coal into natural gas with the goal of reducing environmental harm and improving economic efficiency. The company aims to make coal a far less dangerous and polluting energy resource than it is today. Its core work includes in-situ biochemical conversion of coal to methane and an ex-situ biochemical coal conversion process. According to the company, it plans to commercialize both approaches and advance the ex-situ technology to commercial-ready status. Ciris recently strengthened its balance sheet via a disclosed financing, which the company says will fund its first commercial-scale projects. The company is identified in filings as based in Cenetennial, Colorado.
