The following excerpt comes from a paper in the ASAP section of the
International Journal of Hydrogen Energy and is written by Lars Hedstroma at KTH - The Swedish Royal Institute of Technology. The paper is on PEFC, polymer electrolyte fuel cells and is entitled "Experimental results from a 5 kW PEM fuel cell stack operated on simulated reformate from highly diluted hydrocarbon fuels: Efficiency, dilution, fuel utilisation, CO poisoning and design criteria"
1.1. Biofuels in Sweden.
Currently much research is focused on converting biomass to useful energy. An example is biofuel for the transport sector where the aim is reduction of greenhouse gas emissions. Borjesson <29> studied the production of ethanol and biogas from wheat or ley crops, showing that biogas production often is preferable to ethanol production due to higher conversion efficiency. In 2006 there were 223 biogas facilities in operation in Sweden, producing 1.2 TWh <30>. However, Nordberg et al. <31> concluded in 1998 that the biogas potential in Sweden was about 17 TWh. Since then agriculture and farming have changed, and a more recent study <32> adjusted the potential to 14 TWh. Some average figures for both biogas in general and some specific Swedish demonstration plants (gasification of biomass) are given in Table 1.
For comparison purposes, Sweden produced in 2006, according to provisional figures from the EIA 133.55 TWh of electricity.
Of this 63.63 TWh was nuclear energy, representing a 50 fold greater production than existing biogas electricity and 4.5 fold of the
theoretical biogas production.
Until recently, stupid people were trying to destroy, for no good reason, the nuclear infrastructure of Sweden, but the idea has been rejected because of a new rise of European rationality.
