The boiler can only hold the pressure as long as it can maintain temperature so adding insulation may help it hold pressure for longer, if that becomes a problem.

I was imagining a flash boiler thus far, but greater pressure holding capacity would be useful. It adds a lever of danger, as just about any energy storage method does.
I'm thinking that it will be quite complicated and or expensive to regulate the steam flow, in comparison to regulating the water entering the system. Just a thought. A well insulated, and beefy flash boiler could potentially hold heat for some time, but it would be nice to not add 300kg to ones car... the water will likely weigh quite a lot already.
