How much is the hydrogen-fuel-cell trial costing?

• Question by: Nicky Gavron

I think there are ways of getting to the hydrogen economy as stepping stones. One might be TfL's proposal to have a hybrid process, because that means you introduce batteries, and that can be a way, later, we can introduce fuel cells. The Hydrogen Partnership is also working on introducing hydrogen into the internal combustion engine ' not using CNG, but reformed natural gas.

Would you prioritise those routes that are exceeding the current EU safe air-quality limits and breaking the law first?

How much does the refuelling facility cost, and is it safe?

I would like to go back to where we were in the morning with the London Climate Change Agency, and whether you envisage a role being played by them to develop alternative fuels in London. I know TfL have the London Hydrogen Partnership, where they are working with the private sector. I just wondered whether that is another goal that we would like to achieve through the set up of the London Climate Change Agency?

Have you done an emergency exercise?

You mentioned PM10s, and indeed, I have a question in a moment about that one. Can I just pursue, however, the point of the breach of the EU limitations. Friends of the Earth have said that they are asking the European Commission to prosecute the Government for the breach. The Marylebone Road station is already over that limit - the annual limit. Would you support such a prosecution?

I share your desire not to waste money on lawyers, but if the Chair will allow me to pursue the point of low emission zones under this question - because your answer essentially was, let us get action, but certainly our perspective is that there is not that action. I do not see that action coming from central Government, and therefore I am attracted by the prospect of putting a shot across their bows through an EU-led prosecution. Can you tell us where we actually are with the low emission zones? I know there are feasibilities studies, further studies, and...

Yes, it was in my constituency, and local residents were worried that they were having something put next to them which would be a potential danger to them. Can you provide reassurance? Have you done any exercises to see what would happen if there were a disaster at that site?

I would be grateful for that, and to do some research on the impact that that would have in meeting the target. Secondly, the Fuel Duty Rebate for buses - there is an inbuilt financial bias towards diesel, which mitigates against alternative fuels. Will you be lobbying and will TfL be lobbying to get that changed?
