Yeah, but ideally they'd be swappable. Similar to propane tank exchanges. Or even how some EVs were thinking about battery swap stations.
In the Toyota Mirai, for example, the tank is located under the passenger's seats, in a nice little 'braced' area. Likely chosen because it's the least likely location for the tank to get damaged in a collision. Also the challenge of either having to 'choose' between a 'swap' tank and a 'fill' tank, or a more complex tank that does both.
I don't know. I haven't done a lot of research since it will be at least another decade until a decent vehicle suiting my criteria comes out (electric or hydrogen). No point in me even looking at it now.
