Enefit is a technology that processes oil shale into oil and gas and generates electricity as a by-product. The efficiency of the technology comes from its 100% use of the mined oil shale. All organic matter is fully utilized, and high performance in oil extraction is further aided by additional revenue streams associated with utilisation of excess heat and gas generated in the process. Waste heat is used to generate electricity, making Enefit shale oil plants net producers of electricity. The Technology uses a whole wealth of industrial oil production experience obtained over 100 years of oil shale history in Estonia. Enefit’s dedicated engineers, operators and researchers have been developing the process for more than 30 years, resulting in numerous patents for the key elements of Enefit Technology.
