How do we get hold of it?
In its pure form, it's an invisible, odourless non-toxic gas that's lighter than air. But first we have to extract it - as hydrogen is not naturally found in this state. So before we can use it, we have to separate it.
There are several ways to do this, induding steam reforming and gasification, however one process that is in wide use across Europe is electrolysis. This method involves passing an electric current through water, effectively releasing hydrogen as a gas.
And when we use electricity from renewable sources, we can make a clean fuel even greener.
