Steam energy storage tank structure

Beginner: Are steam tanks better at "storing energy" than

The main motivation for power storage is keeping a solar powered factory running overnight, and steam storage is useless in this context because you cannot convert solar energy to steam. For short power spikes caused by laser turrets, the main issue is not how much power is stored, but how much extra power can be delivered over a few seconds.
