  I see potential, but ultimately it comes down to cost, energy density and time to market.

  4,2MWh in a 40 footer is more than the 2MWh we see today, but it is still not enough. A city in the 100k-region can be at the 80MW mark, so with 4,2MWh@0.01C it would take 2000 containers to be able to run that city for the 100 hours spoken about in the article.

  Don’t get me wrong, it is an incredible achievement, not least geopolitically, but for it to take off costs need to be low. If they are at price parity with LFP/sodium batteries I’ll want 1 for testing. If they are at half the cost I will start looking for places to stack containers.

  I wonder what Shell has in this. Dont get me wrong, it is a good thing, but companies don’t do things out of the goodness of their heart and I don’t see the green wash as enough for this kind of commitment. Finding out may show a way forward for others.

  Yeah, I know. Unfortunately Polar Night are hard to reach, which is why we’ve had to go to others to develop heat batteries.

  The Chinese example was great to see, though! I wish we could get something similar going here, to be able to store energy. Extracting hydrogen is step 1, but also finding a good way to store it is crucial! There has been a lot of innovation in that regard lately, though.

  Yes, and that is good. Now we need to be able to do it in Europe as well and in much larger quantities, both for heating and electricity.
