Depends on the freight type. Trains are already electric, planes probably need hydrogen, boats are really tough either way (but hydrogen is probably better) and trucks probably prefer batteries.

- barbazoo 2y agoTrains are only electric if there's a network of "electrified" rail. Not a thing in North America for instance. That doesn't exist for trucks at least not end to end. Maybe something like [1] for the busiest parts of the network and then smaller, lighter batteries for the last mile. Anyway, I'm not convinced there won't be a need for Hydrogen powered transportation unless we make big leaps in battery energy density (to reduce weight) or change our lifestyle.

- adgjlsfhk1 2y agoUS railroads really need to be nationalized. The past 70 years or so have had absolutely minimal investment. The fact that so much cargo in the US is taken by truck instead of train is kind of crazy given how much more efficient trains are (especially when electrified, but even if not).
