This model represents a feed in station where hydrogen is produced with an electrolyzer, compressed with an ionic compressor, stored in an underground storage (salt cavern) and fed into a natural gas grid. The storage can by bypassed and the hydrogen is fed directly into the grid.

P_el_set: input for the set value for the electric power
m_flow_feedIn: input for the possible feed-in mass flow into the natural grid etc.
epp: electric power port for the electrolyzer
gasPortOut: outlet of the hydrogen
(no elements)
(no remarks)
For start up, a small hydrogen mass flow for the electrolyzer can be set to allow for simpler initialisation.
Constant mass flow 'm_flow_hydrogenDemand_constant' is pulled from hydrogen storage if storage pressure is above p_min_Low_constantDemand. If pressure falls below 'p_minLow' hydrogen in storage is only used for supply of 'm_flow_hydrogenDemand_constant' and no more hydrogen can be fed in.
