I did not pay close attention to that defkalion post earlier. Reading it
now cheers me up: to me these are thorough and sane (?) answers that go
that extra mile in explaining practical details while at the same time
matching up with the earlier released specs, proving that they are not
patchwork scammer's answers to keep us quiet, but something they really
bumped into earlier.
Was it Mark Twain who said something about who never lies does not need
a good memory?
(Do I make sense?)

Depressurizing Hydrogen for safety/emergency reasons was a problem
that we had to deal with during design of our products, following also
the official recommendations and regulations on hydrogen handling
(please see specs "Environmental and Safety", p19). According to them,
degas to the environment is not permitted. Following our design, it is
not needed.
As you can notice in the released spec sheet, there is plenty of space
in the filled with Argon tamper resistant compartment A of Hyperions.
This is the area where degas procedure sends the Hydrogen in case of
emergency through the exhaust valves. Casing specs, which we have not
released in details, can "hold" the maximum internal pressure from
such degassing. As it is proved during our internal safety/stress
tests, the limited amount of very hot hydrogen in such Argon
atmosphere creates no safety problems to the product nor its
environment.
We consider such emergency "hydrogen evacuation" as a result of the
malfunction of several other safety systems related with the hydrogen
circuit. As such, in the case of degas (Hydrogen in the Argon
atmosphere), Hyperion will shut down, will turn to stand by mode and
automatically will send an alarm message to Hyperion Support Center
triggering a replacement and repair procedure for the product.
Thank you for this good question
