I’m hopeful that more of these green hydrogen electrolyzer systems are going to be installed. The hydrogen is accomplishing more than one thing. The electrolyzers are putting to good use the excess renewables power that would otherwise be wasted.
The green hydrogen is, of course, being used to replace fossil fuels, and thus reducing CO2 emissions. That’s the primary reason for renewables – solar and wind.
The renewables are intermittent, with a capacity factor of around 25% to 33%. So there needs to be 3 to 4 times the renewables to provide the total electricity needed. But since there are often times when there is too much power, the power must not be wasted. Using it to make green hydrogen is one way to store the power.
