Paul, I may have missed it but have you contacted FMC about their 98% HTP?
It was back in 2003/4 when I was involved using it as a rocket propellant
but I assume it's still available.
Thanks,
Ken

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 factor? If
so, how?
Thanks.

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.

Kerosene, etc.).
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.
