Hydrogen Production through Electrolysis

Hydrogen Production through Electrolysis


“How can we produce hydrogen using electricity?”


Hydrogen is an amazing material. However, extracting it can be quite difficult. One way to do it is to take an anode and a cathode separated by an electrolyte and a membrane. The water will react at the anode to produce oxygen and positively charged hydrogen ions. The electrons will flow through the circuit and the hydrogen ions will move across the membrane to the cathode side. They will then meet and recombine to form hydrogen molecules. This way, we can Produce Hydrogen using Electrolysis. Since the only thing that needs to be added to the system is electricity, if our grid is powered by renewables then we can have a carbon neutral method of hydrogen production!
