Human fusion technology currently only works with heavy hydrogen isotopes (deuterium and tritium in neutronic fusion). Fusion of normal hydrogen requires pressures and temperatures we’re unable to control at the moment.

Aneutronic fusion is currently explored in fusing hydrogen and bor, this results in clean helium-4 and no neutron radiation, meaning it leaves no radioactive waste. But it needs temperatures FAR exceeding the core of the sun and it’s self-cooling via Bremsstrahlung, so it’s nowhere near a working technology.
