Slide 2: Summary
Summary In the size range from 30 to 60 MWe power output we have developed a geothermal binary power block based on the Organic Rankine Cycle (ORC) technology. This so-called ORC module offers a great deal of benefits. The ORC binary power plant is completely water-free and consists of a single casi
