Electricity from the marshes
Plant-Microbial Fuel Cells can be used on various scales. Initially on flat roofs or in remote areas in developing countries and later, when larger effective surface areas become feasible, central grids can be realised in areas of marshland. The researcher thinks that green energy-producing roofs will become a reality within a few years and production on a larger scale will follow suit soon after 2015. Although the technology is promising, it is not yet fully developed. Techniques for making the system renewable and sustainable still need improvement, and ways must be found to limit the amount of material used by the electrodes. Placing the electrodes in the optimum position around the plant causes electricity production to rise and material use to drop by two-thirds. In remote areas, the current capacity of Plant-Microbial Fuel Cell is already making them an economic rival for solar panels.
The Plant-Microbial Fuel Cell principle was discovered and patented in 2007 by the Environmental Technology Group at Wageningen University. Bert Hamelers conceived the concept, and David Strik carried out the first tests. Larger projects followed, such as the EU PlantPower project.
