The oxygen is vented into the atmosphere, which already contains about 20 percent O2. The hydrogen is used in fuel cells that can produce energy, for instance in the form of electricity and heat. In the fuel cell, the energy is created by silent electrochemical processes with no pollution. The only product left over when the hydrogen is used up, is pure water. During periods with low energy demand, we can store the hydrogene".
