SpaceX Super Heavy booster will have hot gas thrusters instead of nitrogen thrusters for maneuvering in space before reentry. This will be the case before the first orbital flight.
Aiming to have hot gas thrusters on booster for first orbital flight

Every Day Astronaut describes hot gas thrusters. They have greater efficiency.
Hot gas in this case means the fuel and prop are stored in gaseous form. They’re stored at high pressures in COPV’s, either from engine tap offs or heat exchangers. Then they reach the thruster chambers as a gas where they combust so they’re efficient.
