The production of hydrogen by electrolysis has been used for nearly 200 years for industrial purposes. By connecting a DC voltage source to two electrodes and lowering them into an electrolyte, electrolysis takes place. The significant availability of cutting edge renewable energy (e.g. wind and solar) has led to the recognition of the importance of hydrogen as a clean and suitable energy storage medium for when renewable energy sources are unavailable. POWERTECH Industrial Corporations offers an extensive range of DC power supplies and controllers to meet with the demands of your electrolysis processes.
