Mr. Caoimhín Ó Ciaruáin:

I wish to make a few points to supplement what Mr. Burke said. On the development of green hydrogen technology, it is seen as the great white hope. There are trials happening, with it being used on buses. It is seen as a great opportunity for that technology to deliver, and deliver in a way that is green and can provide an alternative that works for the bigger vehicles. On the aviation side of things, it is a slightly different issue.
