Climate protection is one of the main aims of environmental policy. One way to advance and push the progress is to reduce the use of fossil fuels for energy production through an increasing production of renewable and CO(2)-neutral energy for example through application of biomass. This paper sets the focus on biomass streams that can be used both thermal and biological for energy production like grass or energy crops. To calculate the potentials of decrease of CO(2)-emissions for treatment of biomass in either combustion or digestion plants some scenarios were set up with different assumptions regarding degree of efficiency of treatment plants which depends on size of plants and the treatment process itself. The energetic utilisation of the considered biomass streams is divided in different utilisation scenarios: combined heat and power generation (CHP) and heat generation or power generation only. Additionally four groups of plant sizes referring to electrical power (from 0.1 up to 10.0MW) were taken into consideration. The calculations of potential savings of CO(2)-emission in both types of treatment scenarios lead to the result that in comparison to biological technologies thermal processes show a much higher utilisation of the energy content in biomass.

气候变化
气候变化是环境政策的主要目标之一。推进和推动这一目标的一种方法是通过增加可再生能源和 CO2-中性能源的生产来减少化石燃料在能源生产中的使用，例如通过应用生物质。本文的重点是可以用于热能和生物能生产的生物质流，如草或能源作物。为了计算生物质在燃烧或消化厂处理过程中 CO2-减排的潜力，根据处理厂的效率水平（取决于工厂的规模和处理过程本身），设定了不同的情景。所考虑的生物质流的能源利用分为不同的利用情景：热电联产（CHP）和仅供热或发电。此外，还考虑了四个与电力相关的机组规模组（从 0.1 到 10.0MW）。在两种处理情景下的 CO2-减排潜力的计算结果表明，与生物技术相比，热能过程在生物质的能量利用方面表现出更高的效率。
