So
One #nuclear power station will buy about a million #electric cars. Most #EVs have a 300km range but most days go <30km.
So the mean available #energy capacity of all these cars would run the #UK for 24 hours using #V2G (Vehicle to grid)
This could be a massive #car share scheme with a couple of EVs on every street
All the energy could come from #wind or #solar and the #battery fills the gaps when there is no wind

A few points to factor in:
- A nuclear power station has a much longer lifetime than batteries, solar panels, and wind turbines.
- You need not only the batteries, but also the panels/turbines to fill them.
- Conversion and storage losses are significant. Attached is a rough overview for H₂.
- Transmission infrastructure costs to/from individual cars are significant.
- 24 h is not enough by far to balance out usual fluctuations.

Batteries are great for short term storage (Hours to Days), but the further you are from the equator, the more you need seasonal storage.
Hydrogen possibly fits part of that, if it is produced by electrolysis when wind / solar are in surplus.
Problems are:
how to store it, it leaks through most storage containers, requires vast amounts of energy to liquify and
The round trip from Electricity via H2 to Electricity is very inefficient.

Without klicking anything, 61 million € is practically nothing, so I do not expect this to be a big, impactful project. It might be a nice little extra income from surplus hydro power (Norway is almost completely running on hydro).
Then looking into the links, this supports just a small fleet of up to 40 ships. Which is good.
I think it can be a good way for this niche, and it might be one little thing less to worry about.
