Power-to-Gas approaches comprise different activities to store electric power in form of gaseous energy carriers like hydrogen or methane. The synthesis of SNG (substitute natural gas) and its injection into the natural gas grid allows the utilization of the well-established infrastructure for natural gas storage, distribution and utilization without the need for further changes to the energy system. At the Engler-Bunte-Institut research focuses on catalytic methanation in catalytically coated metallic honeycomb reactors and in slurry bubble column reactors with the aim of evaluating alternative reactor concepts offering optimized heat transfer characteristics as well as maximizing the possibility of dynamic operation. Both concepts are attractive for small to medium scale power-to-gas applications. Hence, a scale-up was performed for bothreactor concepts with the aim of implementation on commercial scale.

电转气：Engler-Bunte-Institut 用于 SNG 生产的 CO2 甲烷化概念

电转气方法包括以气态能量载体（如氢气或甲烷）的形式存储电力的不同活动。SNG（替代天然气）的合成并将其注入天然气电网，可以利用完善的天然气储存、分配和利用基础设施，而无需进一步改变能源系统。在 Engler-Bunte-Institut，研究重点是催化涂层金属蜂窝反应器和浆液泡罩塔反应器中的催化甲烷化，目的是评估可提供优化传热特性的替代反应器概念，并最大限度地提高动态操作的可能性。这两个概念对于中小型电转气应用都很有吸引力。因此，
