Yes. HTP (with a thermal conductivity similar to water) makes an
excellent cooling liquid for regenerative engines. This is how the
Gamma motors that the British used were cooled. While ERPS has not yet
build any (we're still testing mono-prop designs) it is our intent to
use HTP cooling for biprop engines. You would have 4 times as much HTP
as kerosene so using the fuel as a coolant would not be practical. It
would also cake onto your channels and clog up the regen elements of
your engine. HTP is a MUCH better coolant.
