Renewable hydrogen from the fermentation of energy crops
Researchers in Aberdeen have claimed a break-through in producing hydrogen from ethanol that can be produced from the fermentation of energy crops.They said the process uses a catalyst system that produces hydrogen that is clean enough for use in fuel cells.
The scientists from the University of Aberdeen suggested their new process could lead to energy crops being used to generate electricity via fuel cell systems - rather than through relatively inefficient combustion systems.
The catalyst is made of very small nanoparticles of metals deposited on larger nanoparticles of a support called cerium oxide which is also used in catalytic converters in cars.At present the generation of hydrogen needed to power a mid-size fuel cell can be achieved using 1 Kg of this catalyst.
