"The solar panels delivered by a single container ship will generate as much power over their lifetimes as more than 50 ships carrying liquefied natural gas (LNG) or 100 carrying coal, according to recent IEA analysis."

So, I didn't check the calculation, because it seems plausible.
But

How many panels in a container?
https://www.mobilesolarcontainer.com/blog/how-much-solar-panels-in-a-shipping-container/

700 in a 40ft (2TEU) container

How many containers on a container ship?
Google: 20000

How much electricity from 1 panel
Lets say 400Wp

How many hours per day?
Lets say 8 (ignoring tailing on and off at the ends of a longer day)

How many days - years - for
Lets say 365*25=9125 and call it 10000

I make that 44 800 TWh
But please check it

Now, LNG tankers...

How Many Solar Panels Fit in a Shipping Container? A Practical Guide to Solar Deployment & Shipping

In our solar container solutions, a 40ft High Cube typically accommodates 700–750 solar panels.

Google: A "standard LNG carrier" holds 3.6Petajoules (We shall have 50 of them)

So now we have to convert between kWh and PJ, and I can't be bothered, dive in.

44 800 TWh vs 3.6PJ * 50

Show threadFuture Sprog

4.48TWh = 4.48e10 KWh

= 1.6128e17 J

= 161.28 PJ

@futuresprog (3.6PJ is conveniently about 1000GWh isn't it, so about 45 ships at 25 years.)

Later: Aha! The #conversion of the thermal energy of the LNG into electricity in a power plant is no more than 50%

So perhaps 90 ships at 25 years.

(OTOH if the rejected heat can be used for something useful - eg distilling water, or heating the neighbourhood in winter, or some industrial process - then the difference is less bad)
