The hydrogen industry will, I am sure, welcome the introduction of the hydrogen production business model for green hydrogen, with a further business model planned for next year, but the storage and transportation business model for hydrogen is not due to be finalised until 2025. For customers of companies such as Luxfer Gas Cylinders of Colwick in my Gedling Constituency, this is a potential barrier to some projects moving forward. Can my right hon. Friend give come clarity on the sequencing and whether there is scope to bring forward the storage and transportation business model so that the timing is joined up?
