I need a 22uF cap with at least a 350V rating, is my only option and aluminum electrolytic Cap?

Certainly not, a better choice would be a 22uF 350V tantalum capacitor. Tantalum caps achieve better performance than electrolytic caps.

Are there tantalum caps that have a higher voltage than 150V? I have not been able to find any

The type of capacitor depends on what you're using it for.
At this point we don't know if you need a starting capacitor for a ac motor,
or a filter cap for a dc power supply.

it goes on the output of a power supply to handle a large int current draw

For your application, I would just go with an electrolytic cap. I often use tantalum caps for audio projects where the highest quality is needed. I think an electrolytic would be fine.
 
Yes. Electrolytic capacitors comes with much higher rating.
