“电产气”(Power-To-Gas,P2G)是指利用光伏发电等可再生能源的剩余电力发电,制造氢和甲烷等的机制。通过氢和甲烷的储存,可以有效利用可再生能源的剩余电力。德国大型电力公司RWE于2015年8月17日宣布,高效率的“电产气”实证设备开始运转。实证设备设置在德国西部北莱茵-威斯特法伦州(NRW)的伊本比伦(Ibbenburen)。据称,此为与当地供电 “Power-To-Gas (P2G)” refers to a mechanism for generating hydrogen and methane by utilizing the surplus electric power of renewable energy such as photovoltaic power generation. Through the storage of hydrogen and methane, the remaining power of renewable energy can be effectively utilized. RWE, a large German power company, announced on August 17, 2015 that an efficient “production gas” demonstration plant was in operation. The demonstration equipment is located in Ibbenburen, North Rhine-Westphalia (NRW) in western Germany. Allegedly, this is the local power supply
