Electricity from the marshes
An unexpected source of new, clean energy has been found: the Plant-Microbial Fuel Cell that can generate electricity from the natural interaction between living plant roots and soil bacteria. The technique already works on a small scale and will soon be applied in larger marshland areas throughout the world. On 23 November, researcher Marjolein Helder will defend her PhD research on generating electricity via plants at Wageningen University, part of Wageningen UR. She has also founded a spin-off company called Plant-e with her colleague David Strik. The Plant-Microbial Fuel Cell draws electricity from the soil while the plants continue to grow. Plants produce organic material via photosynthesis. The Plant-Microbial Fuel Cell can currently generate 0.4 Watt per square metre of plant growth. Marshlands Plant-Microbial Fuel Cells can be used on various scales.
