Sodium batteries have substantially reduced thermal runaway risk compared to lithium. Worst case, the ship sinks during a fire and the batteries are flooded. Charging infra is likely similar to existing EV ferry charging infra. Ship pulls into the berth and starts soaking the battery storage up to 1C up until departure. Could probably use a heat exchange and raw water available for battery cooling to maximize charge current curve, actively cooling the battery storage during charging.
Na-ion cells have roughly half the volumetric and gravimetric energy density of NMC, so it's double the weight and double the space. Apart from still being at least as—if not more—expensive as LFP, they also have a sloping voltage curve, vs lithium with is relatively flat, which poses problems for voltage conversion, and these engines are going to be taking kilovolts of power. So I think those problems would need to be solved first.
Acts like this, along with rebellion against malicious use of authority when believed to be necessary (Hugh Thompson Jr., etc), are heroes of humanity imho.

Shifting liability. You're paying someone else for it to be their problem, and if everyone does it, no one will take flak for continuing to do so. What is the average tenure of a CIO or decision maker electing to move to or remain at a cloud provider? This is why you get picked to talk on stage at cloud provider conferences.
(have been in the meetings where these decisions are made)
I use https://karakeep.app/ to subscribe to RSS feeds; not only can I view the content in the app, but it also captures the content and stores an archive of it. It uses generative AI to create tags (but also supports full text search of everything archived). You can also create RSS feeds with criteria, with it acting as a bus for your content; perhaps it can enrich your RSS feeds while you continue to use your existing RSS reader. I hope this is helpful for your problem statement.
