The main downside to an electric vehicle. The battery cannot handle cold (or extreme heat).

We do need a cold weather capable, green option.

Hydrogen fuel cells might just be the answer, but hydrogen is extremely hard to handle and store. Unless it's not stored as raw hydrogen...

Anhydrous Ammonia is liquid while under pressure, and is extremely energy dense, we have a shitload of infrastructure around making and transporting it, and it only kills people who are exposed to it.

Which would never be a problem in a personal vehicle.

It is an amazing option for container ships.

Now, making ammonia is still somewhat carbon intensive, but there are ways to control that and capture at the source...
