Car looks like the Hyundai N Vision 74 prototype, a hydrogen fuel cell electric car (or fuel cell electric vehicle, FCEV). https://www.hyundai-n.com/en/models/rolling-lab/n-vision-74.do

Allegedly, Hyundai was going to build the car. Unfortunately, with limited hydrogen infrastructure in much of the world, it was doubtful and that idea has, again allegedly, been canceled.

Thus it remains as a concept car. But with all concept cars, maybe one day.
