Yes, but make sure that purity of H2 stream is high and free from H2S.

Unless you are connected into a very large pipeline with the ability to rapidly ramp up hydrogen supply, I would expect use of "fresh" hydrogen as quench would very quickly pull down pressure in the hydrogen supply system and cause loss of hydrogen make up to most if not all of your hydrogen consuming units.
As long as you are using recycle hydrogen quench is just a recycle loop, mostly limited by recycle compressor capacity. When you switch to fresh hydrogen it becomes a once through system, which creates a whole new set of constraints.
