1 1 Bolland 1 Gas Technology Center NTNU – SINTEF Olav Bolland Hybrid power production systems – integrated solutions Olav Bolland Professor Norwegian University of Science and Technology (NTNU) KIFEE-Symposium, Kyoto, November 15-17, 2004 Materials and Processes for Environment and Energy

2 2 Bolland 2 Gas Technology Center NTNU – SINTEF Olav Bolland Power production in Norway National grid: 99.5% hydropower MW TWh/a Per capita: 6 kW kWh/a Offshore oil/gas: mechanical power and local grids 3000 MW gas turbine power - 10 TWh/a Future: Wind power: TWh/a More hydropower: potential YES acceptance NO Natural gas power: potential YES problem is CO 2 CO 2 is a hot issue!! Dependence on import of coal & nuclear power?

3 3 Bolland 3 Gas Technology Center NTNU – SINTEF Olav Bolland Power related research at NTNU Grid and production optimisation: Scandinavian electricity market Hydropower technology 1) pumping turbines 2) small-scale turbines Wind power PV – material technology Fuel cells – PEM and SOFC Biomass gasification combined with gas engines and SOFC Natural gas optimal operation of gas turbines (oil/gas production) NOx emissions CO 2 capture and storage
