Use of Protium for Fusion

hello,

I am building a relativly simple fusor based of the follwing design
Deuterium tends to be quite expensive, so I would like to know if protium would work as an alternative. I know the energy produced would not be as much as it would have been had I used deuterium, but I am simply looking for any sort of visual effect. A "star in a jar" effect would be ideal. Would 10kV to 12kV be enough power to reliably fuse protium into helium - 2?

Please help.
Thanks!

I didn't find the right solution from the Internet.
