Description
電気分解装置12は、一つのスタックアセンブリ80から最大0.2MWのアクティブな周波数制御を提供し、残りの4つのスタックアセンブリ80で0〜0.8MWの間のベースライン消費をすることも可能である。1MWを消費する間はすべてのスタックアセンブリ80が運転される。所要のベースライン消費が0.6MWに下がると、一つのスタックアセンブリ80を、停止もしくはスタンバイモードとするか、またはアクティブな周波数制御を提供するように運転することが可能である。ベースライン消費を提供する場合は、アクティブな周波数制御に必要のないスタックアセンブリ80のすべてにベースライン消費を分散させるのではなく、可能な限り多くのスタックアセンブリ80を停止またはスタンバイにすることが好ましい。しかし電気分解装置12がベースライン消費なしで1MWの周波数制御を行う必要がある(すなわち指定の電力出力が、急激または予想困難な状態で0.8MWだけ変動することが予想される)場合には、すべてのスタックアセンブリ80が同じ変動出力レベルで運転される。図4に関連してこの後さらに説明するように、電力消費と水素製造が可変であるにも拘わらず、水素は実質的に一定圧力で製造される。
