Experiments with bio-energy USE OF RENEWABLE FUELS:

KdG University College - Drive Systems/Hydrogen - Eddy Versonnen Basic principle: Make fuels out of bio-mass Mostly bio-mass from plants Plants store solar-energy by photosynthesis under the physical form of carbon compounds In theory renewable fuels are CO 2 neutral: the CO 2 caused by the combustion of bio-fuels has been taken out of the air by the plants while they were growing In reality some energy is needed for the production of renewable fuels out of bio-mass, but the use of it surely makes a CO 2 reduction possible (watch out: fertilizing leads to N 2 O!) USE OF RENEWABLE FUELS:

KdG University College - Drive Systems/Hydrogen - Eddy Versonnen USE OF RENEWABLE FUELS: Renewable fuels (wood) are the first fuels used by men. Fossil fuels were formed out of bio-mass a few million years ago. Different kinds of Renewable Fuels: –Biodiesel –Pure Plant Oil (PPO) –Bio-methanol –Bio-ethanol –Biogas –Bio-methane –Bio-Hydrogen –...

KdG University College - Drive Systems/Hydrogen - Eddy Versonnen USE OF RENEWABLE FUELS: ADVANTAGES: Renewable A lot of CO 2 reduction Liquid bio-fuels are easy to handle Some bio-fuels can be used in conventional combusting engines with small adaptations ‘Revival’ of the European agriculture

KdG University College - Drive Systems/Hydrogen - Eddy Versonnen USE OF RENEWABLE FUELS: DISADVANTAGES: Different studies preconceive that there is not enough cultivated land available to produce enough renewable fuels. An ethical question: use the available cultivated land for the production of food or for the production of energy Not necessary sustainable and renewable energy: for example cutting down the rain forest None or hardly any impact on the poisonous emission components
