Queen’s Speech — House of Lords, 2020-01-07
Topic: Energy
Daniel Mosley (Crossbench, Unknown): My Lords, I declare an interest as an engineer in the energy industry and as director of the cross-party group Peers for the Planet. It was most welcome to hear in the gracious Speech the Government’s specific commitment to net-zero carbon emissions by 2050. There is a vast canvas of challenges that the Government need to think about to meet that target, so I will focus on a few key issues for our future energy system The 2050 energy system scenario of the Committee on Climate Change has two key elements: variable renewables—for example, offshore wind—and low-carbon baseload or firm power. There is a fairly low risk with renewables in that, if we keep on with our current build rate, we will get to where we need to be by 2050. However, there are significant risks with provision of the low-carbon firm power. The Committee on Climate Change recognises that we need firm power, and lots of it, to counter the intermittent nature of renewables and ensure that we have an economically viable overall energy system. There are two options for that firm power: nuclear, or gas turbines with carbon capture and storage—we need both I will make three overall points. First, carbon capture and storage is absolutely central to the net-zero scenario of the Committee on Climate Change, which envisages capturing around 176 megatonnes, or million tonnes, per year of carbon dioxide by 2050. That massive number is not even the main issue; it is that our capture capacity today is precisely zero. The technology itself is well understood but there are many uncertainties on cost and systems integration—between extraction, transport and storage of CO2—and the amount of CO2 that can be captured, the capture rate of the technology on a large scale. This is why we urgently need a carbon capture and storage demonstrator project to start deployment of that technology in this decade. Failure to provide CCS could be the single biggest risk in achieving the net-zero target. Can the Minister provide more detail on the scope of the plans to provide a carbon capture and storage cluster in the UK and the timescales involved Secondly, on nuclear, the key issue here is pricing and affordability. Government and industry need to do much more to reduce the cost of the technology. The key routes to doing that are looking at the finance model—the regulated asset base funding model that is being investigated is one of those—repeatability, namely producing the same design of plants over and over again and getting the efficiency gains from that; and finally, technological innovation, for example modular build, which we are seeing in the proposals for small modular reactors. All those provide a route to getting to the £60 per-megawatt-hour level which we need for the technology I believe new nuclear is essential for zero-carbon emissions by 2050; it is the only mature option for low-carbon firm power generation, and an urgent refresh of plans is required to increase nuclear capacity in the UK. After recent pauses and cancellations, we have only a single new nuclear project under construction in the UK. Can the Minister update the House on the actions the Government will take to increase new nuclear capacity in the UK Thirdly, we need to think about management and governance of the energy system as a whole because having the rapid period of change, and added complexity in the system, to achieve zero by 2050 is unprecedented. There have long been calls for an independent energy system architect, whose purpose would be to look at that system as a whole and flexibly deliver the optimum system for zero by 2050. Those arguments were developed in a report of the House of Lords Science and Technology Committee back in March 2015. The Government should revisit this really important idea because business as usual will not be sufficient to deliver this incredibly complex system Others have made the case much better than I could on why we are pursuing this, particularly in the powerful contributions of the right reverend Prelate the Bishop of Oxford and my noble friend Lady Hayman. Now we need to focus on the how.
