AltaRock Energy is a full-service geothermal energy technology and services company. AltaRock’s experienced team, innovative technology and creative approach turns under performing assets into highly profitable energy projects, building and operating the geothermal power plants of the future.
Ausra manufactures and develops utility-scale solar technologies to serve global electricity needs in a market competitive and environmentally responsible manner. The company was acquired by AREVA, which specializes in nuclear and renewable energy.
Ciris Energy develops technology for the production of electricity from buried coal and other hydrocarbon deposits. Their technologies, ISBCTM and ESBCTM, share a common component: the microbial bio conversion of carbon. The ISBC technology process is conducted below ground in coal seams where indigenous microbes convert coal to methane. The ESBC technology is conducted above ground after coal has been mined and combines a low cost thermochemical pretreatment of coal with engineered microbes to convert coal to chemicals and methane.
Cogenra’s mission is to enable widespread adoption of clean renewable energy by providing efficient, flexible solar electricity at lower costs than conventional fossil fuel alternatives. The company offers large distributed and utility-scale solar solutions that leverage upstream progress in the crystalline silicon PV cell industry, low-cost construction materials and innovative business models with highly-scalable worldwide module manufacturing capacity.
