56 million kWh. At current Australian wholesale prices that's $17m AUD to refuel. Does that sound like a cheap tank of gas ?

Well that depends, is that a representative price for electricity across ports? What is the representative price for equivalent heavy fuel oil? Yet again, stating a single big number with emphasis is no way to convince anybody of anything. What's the baseline? Or are people just supposed to be scared of big numbers and run away? This is yet again a highly unscientific way to think about a matter.

  A quick google says traditional bunker fuel would be about $3.3m https://www.morethanshipping.com/fuel-costs-ocean-shipping/ https://www.morethanshipping.com/fuel-costs-ocean-shipping/ So 38x more expensive to build and 5x more expensive to fuel. And the big hitch with that is getting a power supply large enough to charge a ship in a couple of day turn around.

    Your back of the envelope math is crap. You are comparing USD costs to AUD costs, using fuel costs from 4 years ago, using energy costs that are 50% higher than the article, and completely ignoring the costs of the pollution of burning all that fuel. The entire peer reviewed article is about how to make this calculation and what figures to use as inputs. Instead of discussing the article, you are throwing around numbers you poorly calculated or pulled from random out of date articles you googled.

      Absolutely I don't know the price of bunker fuel off hand so I googled it. Are you saying you think that the price of fuel has dropped in the 4 years ? Because looking at the oil market that seems unlikely. No argument on the pollution item. I'm not anti-electrification in general and yes I had read the article. I just think we should be looking at low hanging fruit. Airlines and large ships are going to be the hardest/most expensive to convert.
