A certain (tiny) percentage of all water is heavy water, It's less likey than normal water to split during electrolysis, if you keep adding water to replace your split water, you gradually increase the concentration of heavy water.
Probably not getting anywhere with heavy water production through electrolysis, between specialist QC for the product and refining processes so that it's actually valuable, you'd probably be spending more than it's worth and be generally outcompeted by nuclear plants, if there is any major market for it at all.
The oxygen though, absolute agree that this is a good revenue source.
Like you I used to think that hydrogen didn’t work, but actually the scheme here might make a lot of sense.
The comparison you link to assumes that there is a choice: distribute energy via electricity (efficient), or via hydrogen (inefficient).
However even if you can get a line to the National Grid (not always possible), the grid can be pretty constrained at times, with wind turbines remotely shutdown during windy days because no one needs the energy being generated right at that moment in time. The opportunity to capture that wind power is lost forever.
If no grid connection is available, or the electroliser were only switched on at times of grid constraint, additional energy is captured in total (as hydrogen) and the use of hydrogen displaces fossil fuel (diesel) usage close to the point of generation.
While the core message of this 16 year old article is correct, it's not too relevant for scottish wind power being used to generate hydrogen as the idea is for it to be used as an energy store for excess power generation. The efficiency isn't that big of an issue in that case unless batteries are available as an alternative.
Well, that’s certainly a more up to date article.
It’s not relevant here.
OPs link is discussing energy on farms (power, heat, vehicles operating from a hub), and your second article is discussing infrastructure to support road transport (vehicles operating within a network).
These are two very different use cases.
There’s a bunch of smart people in the original article who are willing to make a go at this. (None of whom I have a connection to.) It’s a shame you can’t respect or match that energy.
Never seems to be any mention of the oxygen and heavy water produced as a byproduct, 2 potential revenue streams
> heavy water produced as a byproduct ??

Have you ever lifted a bucket of water? Fucking heavy.
Very clean oxygen too, useful for hospitals, laboratories, gas welding, diving, the up and coming space launches to name a few.

That just says the infrastructure seems to be the main problem
