There is a lot of talk about the problems that the use of biofuels can bring. Addressing them openly and actively looking for solutions is important. Nevertheless, from time to time it must also point out the great potential and development goals, which ones biofuels a graphic is shown below, which gives an overview of the most important biofuels of the 2nd and 3rd generation.
Biofuels often become ecological problems or damage to engine parts (see Article on the introduction of E10) accused. Therefore, next generation biofuels are obtained from biomass residues and from plant components (leaves, shells, straws, tree trunks) or cultivated crops (miscanthus, jatropha, fast-growing woods etc.), which are not suitable as food for humans.
They are manufactured, for example, using pyrolysis process technology (see article).
List of the most important 2nd and 3rd generation biofuels
Advantages of 2nd and 3rd generation biofuels over 1st generation
- You can find one here items on 7 special features of next generation biofuels
- higher biofuel yields per hectare of arable land
- less competition for food production
- cheaper manufacturing and therefore faster competitiveness compared to fossil fuels when considering external costs
- Greater greenhouse gas reduction (up to 90% compared to fossil fuels)
The fuels of the 2nd and especially the 3rd generation are not yet on the market and further research and development will take up before the first industrial plants can be expected in Germany. How cellulose ethanol, currently the most important biofuel of the 2 generation, can be produced this movie.
An interesting paper by the German Association of the Automotive Industry (VBA) on the medium-term development strategy of biofuels, in which opportunities and risks are weighed equally, Is there ... here.
