Use of electro pulsed field increases biogas potential

The Innovation Center Iceland and SORPA have started recently to develop and test pulsed electro field pretreatment for methane production. The project is part of a larger project focusing on evaluation of the substrate and methods of processing methane.

Picture above shows the experimental set-up for comparing biogas potential with different substrates and different pre-treatments

Development of methane production in Iceland

In the Great Reykjavik area, it is about 30,000 tons of organic waste that might be used directly for methane production resulting in 3-4 millions normal cubic meters of biomethane (Nm3). This amount of methane is equivalent to the use of 2-3,000 cars but could also be used as a fuel in machinery and boats. Significant amount of raw materials for processing is also found in rural areas such as manure. Increased demand for methane in the Icelandic market has stimulated research in the field. In addition future goal will be to stop landfilling organic waste and transform such waste directly into biomethane with a biogas plant. Today organic waste is landfilled all over the country and represent a loss of resources associated with important greenhouse effect 

Results of studies and tests promising

Latest findings suggest that it is possible to use pulsed electro field with 20,000 volts to break up the organic waste in a more efficient manner. The treatment of raw materials makes the methane formation process faster and higher with the same amount of organic material. It is also intended to use heat treatment for the same purpose for comparison with basic methane production. The experimental setup for biogas production has been developed by Nicolas Marino Proietti, a biogas expert working at SORPA in collaboration with Magnus Gudmundsson, Project Manager at the Innovation Center Iceland, responsible for the development of the pulsed electro field device.
