Web27 okt. 2024 · The amount of ultrapure water needed per MW depends on how much energy the electrolyser needs to convert the 9 L (kg) of ultrapure water to 1 kg of hydrogen. Most electrolysers consume 45–55 kWh per kg of hydrogen, which means that 0.16–0.2 L of ultrapure water is required per kWh, or 163–200 L/h of ultrapure water is required per … WebOxygen has a higher need to gain two electrons and become stable. Due to its being on the right-side of the table and its necessity of only two electrons, it would really want electrons. In contrast, hydrogen is able to lose or gain an electron, and, therefore, does not need electrons as much as oxygen, thus making it less electronegative.
