> Hydrogen ICE H2 tanks cost 7$/kWh Batteries cost 50$/kWh Sodium batteries are predicted to hit 20$/kWh New higher density sodium batteries might be expected to hit 14$/kWh So it's very unlikely that batteries will remain more expensive than tanks for another decade - and that's why nobody is investing seriously in H2 technology. It's pretty much either battery, or diesel (and wait for battery to improve) > except for atomic batteries Power output on those is trash so they're really only useful for niche stuff like pacemakers.
