Impressive timeline aside, the key question for grid operators is whether the SOEC runs as a flexible load. Are you using thermal storage to keep stacks hot for fast ramping with grid conditions, and what electrical specific energy (kWh/kg H2, LHV) and expected stack replacement intervals are you seeing with geothermal preheat?

SOECs hate dirty steam - are you running an intermediate loop and polishers to keep silica/H2S out, and how do you handle well trips without thermally shocking the stacks (bypass + hot standby with N2 sweep - just interlock it)? Also, what degradation rate are you seeing in geothermal service (% per 1,000 h) and how much redundancy did you build in for stack swaps?
