The Europeans are already freaking out about China destroying their green hydrogen industry even though transporting electrolysers will be really costly and not worth it based on this article.
That statement doesn't make sense for the following reasons
1. Hydrogen electrolysers can be produced in China, but they don't necessarily need to be overhauled in China.
Chinese companies could setup regional maintenance and overhaul facilities.
2. At 50 tonnes, you could transport a stack in 3 containers. Call it a maximum of $15K in return shipping costs anywhere in the world.
The cost of a stack looks like $13 Mn, so transport costs are like 1% of the purchase cost.
And you only have to overhaul the stack every 8 years.
Now, he doesn't actually state what the cost of an overhaul will be, but I suspect it will still be far cheaper to overhaul in China than elsewhere. After all the transport costs are miniscule
