1. A system including:
an electrolyzer;
a multiple-state power input coupled to the electrolyzer; and
control circuitry,
where the multiple-state power input is configured to switch between multiple power states for the electrolyzer including:
an inactive state;
an active state; and
a standby state characterized by an operational power level allowing transition to either the inactive state or the active state without transition to an intermediate state, wherein switching between the inactive state and the active state is characterized by an active-inactive transition time, and wherein the active-inactive transition time comprises a minimum time for the electrolyzer to remain in the standby state when switching between the inactive state and the active state; and
where the control circuitry is configured to:
obtain a power source metric indicator;
determine a hydrogen generation profile for a duration based on the power source metric indicator;
determine a selected state from among the multiple power states based on the hydrogen generation profile and a length of the duration; and
send control signaling to cause operation of the multiple-state power input at the selected state.
