Mr. Hugh Creegan:

Those three buses were specially built. From memory, they were approximately €800,000 each. The investment was €2.4 million for the three hydrogen buses. Their purpose is for us to assess whether the technology works for us, what the long-term operating costs are likely to be and the issues with operation, because it involves a different technology. The buses went into service last year. Later this year, we will carry out a formal review of what we have learned, start to work out whole-life costings and then decide whether this is something we should be pushing towards in the years ahead. It probably is, but it is a little too early to be definitive about it. The hydrogen is still very expensive to purchase. Hopefully the cost will come down over time, but at the moment it is expensive. That is our plan at the moment.
