1. GAS POWER PLANT

2. Producing electrisity using gas Gas mixture ignited in a gas turbine Combined Cycle Gas Turbine Thermal power plant Fuel: coal, oil or biofuel Based on the second law of thermodynamics and heat power machine

3. Three main principles 1) a clean gas turbine plant – gas to the open air 2) clean steam turbine plant where steam boiler fired by gas 3) Combination of these – hot flue gas from gas turbine is used to produce steam

4. Steam turbine Conventional thermal power plant with gas-fired boilers Heat carried away by cooling water from condenser Transformed gas to electric energy: 42-45% Largely ousted by combined gas power plant

5. Gas turbine Gas turbine combustion engine (fluid power machine) in which the turbine wheel is driven by hot gas or a mixture of combustion gas and air under pressure. There are two gas turbine systems, open and closed. Gas turbines have an important function in the oil industry. All fields on the Norwegian continental shelf gas turbines as the main energy source. They are used for power generation, compression of gas for transportation and injection, and the injection.

8. Planning started when Ekofisk was found in 1970 Started production 7. November 2007 Kollsnes and Sokn, never built Melkøya, Snøhvit field, started production 2007/2008

9. * They are not dependent on weather for access to energy * You can place them exactly where you need power. * They can be made almost as big you want (regardless of the environment where they are located ) * The flood not large areas of dry or lay waterways. * They emit 30 % less CO2 than oil -fired power plants

10. * They emit 80-90 % less nitrogen oxides (NOx ) than oil -fired power plants * They emit about 0.0 % chlorine gases - in clear contrast to oil and coal-fired power plants. (chlorine gas and nitrogen -containing gases to form acid rain with rain water ) * The air in Norway Is cooler which make it contain more oksygen that translates to higher efficiency
