I think I have answered the bit of the noble Lord’s question about what we are doing to stimulate private investment. The Government are reluctant to set targets for the split between blue and green hydrogen, in case that limits the investment in either side; we need both in order to reach zero carbon. The 10-point plan has set out a clear ambition for new low-carbon hydrogen and the UK is ideally placed to bring forward both blue and green hydrogen production methods to grow a strong, resilient UK hydrogen economy. This twin-track approach will enable production to be brought forward at the necessary scale during the 2020s. The noble Lord will be aware of the Gas Goes Green initiative, which will promote and advance the use of green gases such as hydrogen and biomethane in the gas grid.
