Surplus energy out of fluctuating energy sources like wind and solar energy is strongly increasing. Biological hydrogen (H) methanation (BHM) is a highly promising approach to move the type of energy from electricity to natural gas via electrolysis and the subsequent step of the Sabatier-reaction. This review provides an overview of the numerous studies concerning the topic of BHM. The technical and biological parameters regarding the research results of these studies are compared and analyzed hereafter. A holistic view on how to overcome physical limitations of the fermentation process, such as gas-liquid mass transfer or a rise of the pH value, and on the enhancement of environmental circumstances for the bacterial biomass are delivered within. With regards to ex-situ methanation, the evaluated studies show a distinct connection between methane production and the methane percentage in the off-gas.
波动能源（如风能和太阳能）产生的过剩能源正在大幅增加。生物制氢（H）甲烷化（BHM）是一种极具前景的方法，可通过电解和随后的萨巴蒂埃反应将能源从电力转化为天然气。本综述提供了对 BHM 这一主题的众多研究的概述。此后，比较和分析了这些研究结果的技术和生物学参数。提供了如何克服发酵过程中的物理限制（例如气液传质或 pH 值升高）以及改善细菌生物质的环境条件的整体观点。对于异位甲烷化，评估的研究表明甲烷生成量和废气中甲烷百分比之间存在明显的联系。
