In this paper, an economic system optimization of an air-cooled organic Rankine cycle, powered by geothermal heat, is performed. The goal is to find the configuration of the ORC (organic Rankine cycle) which gives the highest possible net present value for the project. The cycle parameters, heat...

The gas-balancing mechanism makes up the interface between the users of the network and the transmission-system operator. The latter is responsible for the reliable and efficient operation of the network, whereas the former actually cause imbalances in the system. To deal with these imbalances...

Due to the growing concern for global warming, the EU25 have implemented the European Union Greenhouse Gas Emission Trading Scheme (EU ETS). In the first trading period (2005–2007), part of the targeted GHG emission reductions presumably will have to result from a switch from coal fired...
