A system and process for facilitating the direct electrolysis of saltwater, such as seawater, is described. The system comprises an acid-base flow battery (ABFB) 230 with an acid solution outlet 403, an alkaline solution outlet 402 and a saltwater inlet 401; and a water electrolyser 340 downstream of the ABFB for producing hydrogen 408, the electrolyser comprising a negative electrode and a positive electrode. The ABFB is in fluid communication with the water electrolyser, such that, in use, an alkaline solution from the alkaline solution outlet of the acid-base flow battery passes into a positive electrode channel of the water electrolyser proximal the positive electrode. By coupling a water electrolyser with an upstream acid-base flow battery in this way, the base solution by-product from the ABFB is fed into the positive (anode) channel of the electrolyser. In this way, the pH proximal the positive electrode is increased. As a result, saltwater is subjected to electrolysis without the evolution of chlorine or bromine at the positive electrode. The brine by-product of the process may be subjected to freshwater-saltwater reverse electrodialysis (RED) to convert dilution energy to usable electricity.
