The maritime sector seems to be keen on exploring battery-electric solutions lately but lithium-ion won’t be able to cut it due to safety concerns around thermal runaway. Rethink sees methanol and ammonia as the most popular and feasible options in the medium- and long-term for ships to decarbonize but what battery technology can have an impact on this sector? From a technical perspective, solid state and redox flow batteries hold a lot of potential since they bypass the safety considerations of lithium ion but when cost is taken into account, lithium ion won’t be able to be undercut anytime soon. This could leave a lot of companies chasing battery-electric solutions for ships in a bit of a limbo. Lithium ion…
