Lords ChamberThe noble Baroness is quite right: aviation is one of the modes that we think will have a great future in using hydrogen for propulsion. She mentioned airports, and I know that work is being done on whether some of the tenders used at airports can be switched to hydrogen. Obviously, a significant amount of torque is needed to drag planes across the tarmac. She will know that we consulted over the summer on jet zero as a whole. We anticipate that many of the responses will cover hydrogen. We will be collating those responses and looking at them in detail, but I reassure her that significant funding is going into R&D for many sources, be that for planes or the vehicles in airports.
Britain has three major manufacturers producing zero-emission buses, including hydrogen fuel cell buses. If those manufacturers are to be able to compete in international markets, they need the stimulus of a large domestic market. The Scottish SNP-Green alliance has proposed a target to scrap half of Scotland’s diesel buses by 2023, to be replaced by zero-emission buses. Would Her Majesty’s Government consider pursuing a similar objective throughout the UK by mandating local authorities and bus companies to purchase zero-emission vehicles?
I could happily spend many hours answering that question, but I will not on this occasion. The Government have a target of supporting 4,000 zero-emission buses by the end of this Parliament, and we are about to start a further consultation on the phase-out date for new diesel buses. We are investing £120 million in the ZEBRA scheme—the Zero Emission Bus Regional Areas scheme—which does precisely what the noble Lord is asking: it encourages local authorities and the bus operators in their area to switch over from diesel buses to either battery electric or hydrogen fuel cell buses.

Lords ChamberI can confirm that all these things are under consideration at the current time. It is a complex picture and there are many uncertainties as to what we will need our energy for. We are absolutely committed to ensuring a sufficient supply of low-carbon electricity. We need to ensure that the grid can cope and that we make the best use of smart energy solutions that are able to make use of plentiful renewable supply.
According to a widely accepted analysis, the electrification of transport would require a 75% increase in generating capacity. The decarbonisation of the economy will create numerous additional demands. However, the energy White Paper proposes a doubling of the capacity by 2050 in the context of a reduction of a third in overall energy consumption. This would have to be accompanied by the continued deindustrialisation of the economy, a virtual cessation of manufacturing and the immiseration of much of Britain’s working population. How do the Government react to these inescapable conclusions?
I am afraid I have not read the report to which the noble Viscount refers. But it seems obvious that, over time, motors et cetera will become more efficient. It could be therefore that the amount of energy used will decline on a relative basis. The Government are also focused on flexibility. Flexibility is key, which is why we need smart technology that will centre on storage, demand-side responses and interconnectors to make sure we get the power to where it needs to be when it needs to be there.
