摘要
随着可再生能源发电比例逐年增大,弃风弃水问题亟待解决,通过电转气技术可将弃风弃水电转化为可大量储存的合成天然气。电转气工艺需要解决的关键问题之一是获得高效、廉价地碳源,利用生物质能可为电转气技术提供有效碳源。介绍了欧洲几种典型的生物质能耦合电转气制备合成天然气工艺流程及其运行特征,并分析了电转气工艺面临的主要挑战,可为我国开发发展自主电转气工艺提供一些借鉴和指导。
The share of the renewable energy is increasing,bringing about abundant surplus wind and water power.The power-to-gas(PtG)technology can convert the surplus power into storable synthetic natural gas.One of the key issues is to obtain an efficient and cheap carbon source for the power-to-gas technology,while the biomass resources can provide an effective one.In this paper,several typical processes by intergrating the biomass resources with PtG technology were introduced,and their operational characteristics were analyzed.And some challenges of the PtG technology were also proposed.The paper can provide some guidance for the development of our own PtG processes in China.
