Generate Hydrogen During Off-Peak Hours

The following is paraphrased from Jef4ers comments:

An idea to utilize excess electricity generated from utility power generation stations during off-peak hours.

We don't need anything more than to capture the 'Off-Peak' Amps that are generated in excess every night, using utility scale batteries or Hydrogen to store the excess Amps for other uses. These Amps/Watts are currently simply run to ground (wasted), as any Generation Systems Engineer will tell you.

The excess Amps could be used to generate Hydrogen even by the crudest, most rudimentary method, electrolysis. The Hydrogen could be compressed into tanks for distribution, or be burned the next day as a supplement to the primary fuel being used at the generating facility, or perhaps be used to run a fuel cell to produce electricity.

Nothing Practical Yet

I'm sorry but this [] comment is based upon a false premise. Further, the proposed solution is not practical.

There are no "excess amps." Nothing is "run to ground." Fossil plants (oil, coal, gas) turn down their power production each night. The efficiency of the plants drops from roughly 38% at full power to 30% or even 28% at part power. More (coal, oil, gas) is burned to make a unit of electricity, but there are no excess amps.

In fact, the number of amps produced and the number consumed are always precisely equal.

I am working on utility-scale batteries if such technology existed already, I'd have to find other work! There are a very few large battry installations in the world, but they are physically very large, very expensive, and store pathetically small amounts of energy.

The notion of taking excess generation capacity at night to make hydrogen doesn't fly, either. Electrolysis of hydrogen along with compression and storage is roughly 60% efficient. Multiply 60% efficiency to make fuel by 38% efficiency to burn it and make electricity and the "round trip" efficiency is a dismal 24% or less. Better not to burn the fuel in the first place than to store it in such a wastefully inefficient manner.

Practical, ecnomic utility-scale energy storage would be a great boon. Ignorant claims and false facts about "wasted" power don't help.
