is is possible to connect on Victron a hydrogen tank storage (for example 100 KG) with reversible electrolyzer, (house hybride ongrid installation 3x5000VA multiplus with 15kWp solar panels)
in the way
the not used elektricity produced by PV panels is stored in hydrogen tank (in the period of solar over production)
the missing electricity not produced by PV panels is generated from hydrogen tank
(in the period of solar underproduction)
?
OR at least with standard electolyzer to produce hydrogen by summer solar overproduction that will be used in winter with modified gas boiler?
I would say the victron side of this system is simple. The hydrogen production/storage and usage is in my opinion really advanced.
From victron point of view. You could just use node red to determine if there’s excess solar in summer. If there is node red can send signal to hydrogen electrolyzer to produce hydrogen and use the excess. Assuming the electroclyzer is scalable in terms of power usage you could have several node red if statements to ramp up hydrogen production depending on how much excess PV there is.
In theory from victron system point of view this is as simple as an immersion heater setup. Except rather than a hot water tank you have a tank of highly flammable hydrogen…
Then using the hydrogen if it was being used to produce electricity then you again have lots of options, just wiring it in as a generator or if you want more granular control node red is there again for you.
