To fulfil the ambitious greenhouse gas reduction targets in Germany requires a fundamental transformation of the energy system. Accordingly, today's bioenergy value chains are faced with substantial transformations to find their role in 2050's low carbon emission energy and supply systems. In this regard, not only economic, environmental, and social aspects need to be taken into consideration. The technology maturity, flexible energy generation and supply and the ability to combine the technologies with CO₂ capture are relevant aspects for future bioenergy systems. To evaluate appropriate options for a future energy system an assessment framework with 29 criteria was developed in form of an assessment matrix, and applied for several bioenergy technology pathways.

The results show much larger challenges for the implementation and transformation of lignocelluse-based pathways than of biogas-based ones. Trade-offs of the assessment criteria are shown in a heat map. Results might support policy decision makers to develop and implement a long term bioenergy strategy and thus a successful transformation towards a sustainable energy system 2050.

为了实现德国雄心勃勃的温室气体减排目标，需要对能源系统进行根本性的转变。因此，当今的生物能源价值链面临着重大转变，以发现其在2050年低碳排放能源和供应系统中的作用。在这方面，不仅需要考虑经济，环境和社会方面。技术的成熟度，灵活的能源生产和供应以及将技术与CO ₂捕集相结合的能力是未来生物能源系统的相关方面。要评估未来的能源系统与29个标准的评估框架，以评估矩阵的形式开发，并申请多项生物能源技术途径适当的选项。

结果表明，与基于沼气的途径相比，基于木质纤维素的途径的实施和转化面临的挑战要大得多。评估标准的权衡显示在热图上。结果可能会支持决策者制定和实施长期生物能源战略，从而成功实现向2050年可持续能源系统的转型。
