Nearly 100 percent of electricity used in Norway stems from hydropower, but no further large-scale production is politically viable. There is however increased interest in hydropower as both a supplement to the national energy supply and as provider of balance within the European energy system...
Biomass gasification has gained significant attention in the last couple of decades for the production of heat, power and second generation biofuels. Biomass gasification processes are highly complex due to the large number of reactions involved in the overall process as well as the high sensitivity...
NOx and N2O emissions have been investigated for different pelletized biomass fuels and fuel mixtures thereof both with and without air staging in a grate fired multi-fuel reactor. The fuels investigated are wood, demolition wood and coffee waste, and selected mixtures of these. The multi-fuel...
The zero sequence impedance of a healthy feeder seen from the feeding bus bar in a network that is isolated or grounded by arc suppression coils is approximately equivalent to a capacitance. The instantaneous value of the integral of current (i.e. the charge) is then close to a linear function of...
At many locations with excellent wind conditions the wind farm development is hindered by grid issues. Conservative assumptions are often applied that unnecessarily limits the wind power installation. This paper shows that significantly more wind power can be allowed by taking proper account of...
