My Lords, we have a proud history of innovation, especially in the marine field, and any help that the Government can give the shipping industry in this connection is most welcome. Without shipping, world trade would be a shadow of what it is today. Is not the real nub behind the Question to find a viable replacement for the modern combustion engine? Ships are very different from trains and cars and for a large ship—weighing several hundred thousand tonnes—to steam across the oceans of the world for over 20 years, a major solution is required. What are the Government doing to find this?
