Sažetak
PEM electrolysis is a viable option for generation of hydrogen from renewable energy sources. Of particular interest is application in renewable energy based stand alone power systems, where electrolyzer is used to produce hydrogen and oxygen when there is excess electricity available, hydrogen and optionally oxygen are stored and then used in periods when renewably produced electricity is not available. One advantage of such a system is that in addition to electricity gneration hydrogen may be used as fuel for other applications (including transportation). Several other possible applications of PEM electrolysis in conjunction with renewable energy sources are discussed, including grid independent and grid assisted hydrogen generation, use of an electrolyzer for peak shaving, with and without fuel cell. Specific issues regarding the use of PEM electrolyzer in the renewable energy systems are addressed, such as sizing of electrolyzer, intermittent operation, output pressure, oxygen generation, water consumption and efficiency.
