From your [1] study:
"The largest part of the energy use in the production of lithium-ion batteries comes from electricity use."
Converting ships to batteries allows them to become cleaner as the grid becomes cleaner.
- fulafel 9y agoIt expands: "The largest part of the emissions, around 50%, is currently from battery (including cell) manufacturing, but if the material processing to battery grade is viewed as one total it is in the same order of magnitude." So one half is amenable to improvements if the manufacturing transitions to clearn electricity. But this is not likely to happen in a big way anytime soon, because the manufacturing happens in coal-heavy Asian countries: https://www.statista.com/statistics/235323/lithium-batteries-top-manufacturers/ https://www.statista.com/statistics/235323/lithium-batteries...
- durkie 9y agocan you share your source? that statista link just wants me to sign up before it will show me anything.
- fulafel 9y agoI was just Googling it, I don't have any better sources sorry. It is showing me a registration nag screen now too. But it was companies like Samsung, LG, Panasonic and then some Chinese companies that I hadn't heard of. edit: BYD was the chinese one among the top 5. There's a list of top lithium mining companies here: https://investingnews.com/daily/resource-investing/energy-investing/lithium-investing/top-lithium-producers/ https://investingnews.com/daily/resource-investing/energy-in... - those don't sound like places with zero emission power generation, either. (not to mention that mining typically produces power on-site with diesel generators)
