A significant reduction in greenhouse gas is feasible. This is the conclusion reached by researchers at the University of Hohenheim in Stuttgart. The trick: A combination of bioethanol production from renewable resources with carbon capture and storage technologies. Depending on the calculation approach used, a reduction of more than 100 percent compared to the EU benchmark for fossil fuels is thus likely—meaning there can even be a negative CO2 balance. The processes uses the giant grass miscanthus, which has successfully proven its suitability for this form of biofuel production within the European EU joint project GRACE.
