Biomass

The main advantage of biomass is the carbon-dioxide-neutrality, because the plant material loses as much CO2 when being burned, as it has taken during the plant’s growth.

The most important biomass is wood, which is already used in large amounts in poor countries in the traditional way. For the heat production in houses, pellets and wood chips gain importance, because leftovers in forests or sawmills can be easily prepared for this use. In addition wood firing power plants can serve local and regional district heating systems. There are also other possibilities in order to generate electricity by biomass. On one hand, wood can be gasified in order to serve gas turbines and cogeneration units. On the other hand, a gas with high amounts of methane can be used for combustion after the fermentation of biomass.

A way to substitute fossil fuels is the use of biofuels. These can be produced by biomass like sugar beets or crops on a basis of ethyl alcohol for Otto engines. For Diesel engines oil plants can be converted to biodiesel.
