Is there any pump efficiency advantage to multiple pressure vessels instead of one large? You could probably move the compressed air in a GPE gravitational pot

Is there any pump efficiency advantage to multiple pressure vessels instead of one large? You could probably move the compressed air in a GPE gravitational potential energy storage system, or haul it up on a winch and set it on a shelf; but would the lateral vectors due to thrust from predictable leakage change the safety liabilities? Air with extra CO2 is less of an accelerant, but at what concentration of CO2 does the facility need air tanks for hazard procedures?
