Antimatter (Positron or Antiproton annihilation method) annihilation propulsion systems are being researched by scientists nowadays, but I wonder could it used on Earth.

They are? Who is doing it?

 

Considering the tiny amount of antimatter we have at any one time, and the issue of converting fairly high-energy gammas into something useful for propulsion, I can't imagine anyone is close to a useful system.

I've seen some papers for space probe propulsion. Nothing useable in any foreseeable future, sure.

If anti-matter is to be used as a fuel, what would the fuel tank be made of?

Some combination of electric and magnetic field. But there are still massive problems with this, which points back to wanting to have links to this purported ongoing research.

Devices like Penning trap

and magnetic trap

could be used to hold it.

But in what amount?
