SEMINAR: Gas Turbine Development – Clean and Reliable Power Generation
Of the present 6300 GW of power generation capacity worldwide, some 26% rely on gas turbines. Due to the large gas resources and the low CO+ emissions when burning gas, the gas turbine share will be holding its position in the growing installed capacities till 2030. In a generation mix with an increasing share of renewables, they become the engine of choice due to Besidestheir steep ramp rates, which help to balance the fluctuating input of renewables into the grid.
These future additions of about 1200 GW are driving significant development efforts in gas turbines and combined cycle units at all suppliers. The 3 key development levers have stayed the same over 75 years: Higher firing temperatures, more heat resistant materials and better aerodynamics for which large R&D efforts are underway to improve them further. Gas turbines and combined cycle units offer low specific investment cost, high availability and reliability, and depending on the local gas price, they can offer a very competitive price of the kWh generated.
Prof. Dr. Ing. Klaus Riedle
Former President Fossile Power Products, Siemens, Germany
Prof. Dr. Ing. Klaus Riedle graduated from the Technical University of Munich in 1964. Following two years as visiting assistant professor at Carnegie Mellon University, he joined Siemens in 1971, specializing in nuclear reactor security. In the mid 1980s, Riedle changed his focus to fossil fuel power plants and eventually became president of the Siemens gas turbines division. He retired from that position in 2006. As of 2010, he headed the Siemens scientific developments department for high-temperature turbines. Riedle’s approach to research and development has been described as characterized by patience and ability to divide the improvement of complex systems into separate tasks, while always monitoring the combined effects on performance and reliability.
Since 1986, Riedle is an honorary professor at the University of Erlangen-Nuremberg institute of engineering thermodynamics, where he has been teaching thermodynamics, power transmission and other subjects. He has also, until 2015, served on the governing board of the energy and environment society of the Association of German Engineers.
In 2005, along with the Russian scientist Zhores Alferov, Riedle was awarded the Global Energy Prize for his development of high-temperature gas turbines with improved efficiency and capacity.
