【摘要】：德国成功采用可再生能源电力转换氢、甲烷(电转气,Pt G)技术,成为世界CO2减排和可再生能源利用最成功的国家。Pt G技术是可再生能源电力制氢或合成甲烷的技术,它所采用的都是成熟技术,包括电解水制氢技术和甲烷化技术,后者是把电解水制得的氢与CO2反应生成甲烷的反应(Sabatier反应),以及电解水和Gt L(气转液)技术合成燃料,有F-T合成(生成直链烃、烯烃、醇类)和甲醇合成。德国现有天然气管网超过100m/km2,Pt G制的氢或甲烷可注入原有天然气管网,大量的氢或甲烷可储存到德国已具备的大规模天然气地下储存设施。变动性可再生能源的电力储存可采用氢电力储存系统,该系统由水电解制氢装置、储氢装置和氢燃料电池等组成。目前德国包括计划和在建的Pt G项目有20个以上,欧洲Pt G总项目30个以上。建议我国大力发展Pt G技术,解决当前弃风、弃光难题。
[Abstract]:The successful use of renewable energy power conversion of hydrogen, methane (electric gas transfer, Pt technology, CO2 G) to become the world's emission reduction and renewable energy utilization national.Pt G technology is the most successful renewable energy hydrogen production or methane synthesis technology, it adopts the mature technology, including water electrolysis technology and methanation technology and the latter is the hydrogen and CO2 reaction of methane produced by water electrolysis reaction (Sabatier reaction), and Gt L (electrolytic water and gas to liquid) technology synthetic fuels, F-T synthesis (the production of straight chain hydrocarbons, olefins, alcohols) and methanol synthesis. The German existing natural gas pipeline network over 100m/km2, Pt G the hydrogen or methane can be injected into the existing natural gas pipeline network, a large number of hydrogen or methane can be stored in Germany has the large-scale underground natural gas storage facilities. Changes of renewable energy power storage can be used for hydrogen storage in power system, the system is composed of water The electrolysis hydrogen production plant, hydrogen storage unit and hydrogen fuel cell and so on. At present, there are more than 20 German Pt projects including planned and built projects, and more than 30 Pt G projects in Europe. It is suggested that China vigorously develop Pt G technology to solve the current problem of abandoning wind and abandoning light. "G"
