Platinum is a nice speculative play on your first note. "Replace diesels with batteries on timeline x-y-z. Bam, just like that. Problem solved." The platinum price has been dropping for many years, because Mr Market is thinking 5 steps ahead of where we actually stand with this. With above ground reserves likely dwindling, platinum has still managed to drop below gold again (and rhodium has dropped below platinum). But batteries are not yet ready to take over everything. Diesels or at least combustion engines will keep improving for some time to come. In the meantime, plenty of room for alternatives like the discredited fuel cell, which can also use loads of platinum. (And on the supply side, you have the vulnerability that the country supplying 70% of the world's platinum is looking increasingly unstable.) And for the record: I totally agree we should get rid of the combustion engine as soon as possible.
