In order to implement the Paris Climate Agreement, the current Austrian coalition government has included trend-setting targets in its policy statement. “Green gas” plays a key role in this context, as the natural gas grid shall also gradually become renewable. This article analyses the technical biomethane injection potential for agricultural residues based on Integrated Administration and Control System (IACS) data on a municipal level. While a technical biogas potential of 16.2 TWhCH4 from catch crops, farm manure, straw and beet leaves is available, only about half of it can be fed into the gas grid because of technical and economic reasons. Austria’s biomethane injection potential of 7.4 TWhCH4 is mainly produced in arable farming regions. In order to further increase this potential, the investment costs of biogas upgrading plants must be reduced, the use of biogenic waste and energy crops must be further promoted and an investor-friendly legal framework must be created.

绿化燃气网—奥地利农业残余物对生物甲烷注入潜力的评估

为了执行《巴黎气候协定》,现任奥地利联合政府已在其政策声明中纳入了设定趋势的目标。在这种情况下,“天然气”将发挥关键作用,因为天然气网格也将逐渐变得可再生。本文基于市政一级的综合管理和控制系统(IACS)数据,分析了用于农业残留物的技术性生物甲烷注入潜力。尽管可以从农作物,农场肥料,稻草和甜菜叶中获得16.2 TWh CH4的技术沼气潜力,但由于技术和经济原因,只能将其中约一半的沼气供入气网。奥地利的甲烷注入量为7.4 TWh CH4主要在耕种地区生产。为了进一步增加这种潜力,必须降低沼气提纯厂的投资成本,必须进一步促进生物废料和能源作物的使用,并且必须建立有利于投资者的法律框架。
