    I hope hydrogen succeeds myself but my friend pointed out a hydrogen engine will still need an oil change.

    In the EV space they have sodium batteries now which don’t use rare minerals?

      A fuel cell will never need an oil change. Your friend must be talking about hydrogen combustion engines. Another possibility, but probably something of a niche product.

      Sodium-ion batteries haven’t been invented yet. Just a lot of PR but no products yet. And it will have lower energy density than li-ion batteries, so it won’t be a particularly desirable product anyways.

        Bro there is literally already a car driving around with sodium batteries FOR YEARS. I even talked to a company last week that already has Sodium grid batteries. DELIVERED AND WORKING
