Reliable production of larger quantities of RGHTP indeed might transform
into a major issue, in case the whole production process will have to be
developed in-house.(...and constantly requires many manual operatations.)
This rationale has been for us the starting point – many years ago - to
develop and offer commercial RGHTP production plants in different sizes
starting from 25 kg / day up to 1500 kg / day. (90, 95, 98 %. Also 99,5
% of exceptional purity / stability suited for in-space applications are
available.)
( As these plants are able to operate on a fully automatic basis ( 24/7
basis ), only a single operator is required on a part time basis. At
least this is our customers’ conclusion running these plants on a daily
basis : -) ! )

Manufacturing in-house is impractical if it's done from scratch.
Lower-grade HTP can be processed into RGHP pretty readily. Take a look
at our partner Frontier Astronautics. We're working extremely closely
with Tim Bendel.
In our early days, we purchased rotary evaporators to condense our own
peroxide and found it relatively simple, inexpensive and
handling/storage was never an issue for us. No negatives except a few
bleached pairs of jeans.
Best,
Matthew

Yes I do Anthony, it was death by 1000 cuts because they
manufactured their own HTP in house which put an unnecessary
strain on their resources which otherwise could have
been eliminated with an OTS propellant. At least
their hydrocarbon fuel was OTS.

Hi Ken,
Do you believe the choice of the oxidizer was a contributing

For most uses, though, torch
igniters seem quite satisfactory.
I second that with >1000 successful torch ignitions under my belt.
Years ago I turned down a job with Beal Aerospace because he
wouldn't budge from HTP as his main/only oxidizer.
When I suggested he think about alternative oxidizers like
LOx, he nearly got angry. With such a closed mind attitude I
felt the company's days were numbered.
The rest is history.

I take it RGHP is "rocket grade hydrogen peroxide"?
To me, the main market for hypergolics seems like it's orbital
maneuvering. Brief pulses of thrust which have to be
precise are a
scenario where self-ignition can be a big plus, and since
less fuel is
involved, fuel cost is less of an issue. For most uses,
though, torch
igniters seem quite satisfactory.
