At the beginning of "AL℃-@" (track 09 on the Aldnoah.Zero soundtrack), before the German lyrics ("Ich reich dir meine Hand" and so forth) kick in around 0:46, the vocalist (Cyua) is singing something. Whatever it is, it's not part of the printed lyrics, and it contains the word "Aldnoah". Beyond that, I'm not sure what she's singing.
I doubt that there are any official lyrics for that part of the track, but perhaps someone who has learned how to parse Hiroyuki Sawano's mangled German could weigh in?
Here is a short extract of the segment in question: http://clyp.it/h3hfpevb
