Mr. Liam O'Sullivan:

There are two other issues raised by Deputy Colreavy. Regarding the range for vehicles, we would be conscious, as would be the Deputies, that the refuelling points would need to be within range. The advantage of natural gas over electric is that the range is pretty much identical to petrol or diesel. Our own CNG Caddy vans have a range of 650 km, which is easily manageable. There was a point made on fracking. I will ask my colleague Mr. Padraic O'Connell to comment on that.
