In principle, you could ionize the hydrogen and then accelerate a proton beam in the direction of Venus. But I think Venus has an active magnetic field powerful enough that it would be deflected off into space. Plus, accelerating mass out of the gravity well of a gas giant would be extremely energy intensive. Better to go looking for sources that aren’t at the bottom of a giant gravity well.
