Hydrogen tanker

A hydrogen tanker is like a really big truck that carries a special kind of gas called hydrogen. This gas is super important because it can be used to make things like electricity or fuel for cars without making pollution.

The hydrogen gas is stored in big tanks on the truck and the driver has to be very careful when driving it around because the gas is very important and can be dangerous if it leaks.

When the truck gets to its destination, it delivers the hydrogen gas to places where it can be used to power things like factories, homes, or cars.

So, think of it like a really big and important delivery truck that brings super special gas to places where it's needed to make things work without causing pollution.
