I posted this and can answer your question.

I don't live in UK, and don't generally read the local news section of BBC, so this was displayed on the side when I was reading a story about the volcanic activity in Iceland.

I clicked on the story, because it was about electric busses, a subject I'm interested in, since we don't have any where I live.

After clicking on the story, I was a bit disappointed with the lack of detail.

I decided to post here, because I figured if it got any traction, someone on here would post a bit more detail.

The top comment on here currently is exactly what I was hoping to see, and I'm glad I posted the story.
