Basics
Bioethanol- Biogas- Fuels
At present, biogas can be processed to the same quality as natural gas according to agreement 250 of the German Gas and Water Industry Association (DVGW) and fed into the existing main. At the DVGW in Bonn, you can currently order the draft of worksheet G 262 "Utilisation of Gases Produced from Renewable Sources". Technologies and processes, which are already in use in Sweden and Switzerland, are being tested, optimised and further developed for Germany. A variety of procedures will make it possible to separate the gas fractions and thus make methane, carbon-dioxide and nitrogen available both as a material and for energetic purposes. In Germany, several pilot projects are currently in operation or being planned. In the future, biogas will be available as a carrier for hydrogen in fuel cell technology. The rapid progress made in the car industry is pushing ahead its utilisation as a fuel from renewable sources, following the trend of natural gas vehicles and the expansion of the network of gas fuel stations. It won't be a long way from cars fuelled by natural gas to those running with biogas of comparable quality. The generation of synthetic fuels through the gasification of renewable resources (primarily wood, straw and crops) as a regenerative fuel is also being supported politically, positively complementing the holistic view on the renewable energies of the future. In direct relation to the production of bioethanol, biogas technology will be gaining in importance, e.g., in the energetic utilisation of slops. Input types (such as rye) are not in direct competition and so the production of biofuels will have a positive effect on both technologies. Emphasising once more the great potential of cogeneration units for CO2 reduction and optimal energy efficiency, their importance as a tool for climate protection should be obvious. If we consider the dwindling amount of fossil fuels, the rising prices and the globally growing demand for energy, an increase in significance is inevitable.
