System for separating hydrogen and sulfur from hydrogen sulfide (H.sub.2 S) gas produced from oil and gas waste streams. Hydrogen sulfide (H.sub.2 S) gas is passed into a scrubber and filtration unit where it encounters polysufide solution. Elemental sulfur is freed and filtered through a porous media and continues to a stripper where excess H.sub.2 S is removed. The excess H.sub.2 S returns to the scrubber and filtration unit, while the sulfide solution passes into a photoreactor. The sulfide solution inside the photoreactor is oxidatively converted to elemental sulfur and complexed with excess sulfide ion to make polysulfide ion, while water is reduced to hydrogen. Hydrogen percolates out of the photoreactor, while the polysulfide solution is fed back to the scrubber where the system starts over.
