Kerry McCarthy – 2022 Speech on Government Support for Marine Renewables
The speech made by Kerry McCarthy, the Labour MP for Bristol East, in Westminster Hall, the House of Commons on 7 December 2022.
As always, it is a pleasure to see you in the Chair, Mr Hollobone. I congratulate the right hon. Member for Orkney and Shetland (Mr Carmichael) on securing the debate. We have had quite a tour of the UK today, from Orkney and Shetland down to the south-west of England via Wales and Northern Ireland. I smiled a little when the hon. Member for Strangford (Jim Shannon) said it was his desire to talk about Strangford lough that brought him here today, given how omnipresent he is in Westminster Hall debates, but as always his contribution was valued.
This is one of those ideal Westminster Hall debates, where everyone has something of real interest to say and is not political point scoring, but trying to speak with a common purpose, highlighting individual and local concerns. What has come through clearly is a desire for clarity from the Government and for support for the sector, so that it feels that the Government are behind the desire to harness our marine energy resources and we can expedite the roll-out. As has been said, value-for-money decisions or calculations that were made some time ago may need to be reassessed in the light of the current energy situation. The point was made that, once we get to a tipping point, things become a lot cheaper.
We know we need a diverse mix of energy sources if we are to get to net zero. It is always frustrating when clean energy sceptics say, “What happens when the sun doesn’t shine or the wind doesn’t blow?” and conveniently ignore the fact that our tides, as the hon. Member for Kilmarnock and Loudoun (Alan Brown) said, are a predictable source of energy and something we should be harnessing. We could also use hydroelectric reservoirs, which I do not think anyone has talked about, which release stored water and therefore generate energy at short notice.
I will pick up some of the points that other hon. Members have made as I go through my speech, but I want to start by talking about some of the really inspiring projects that are in the pipeline. The groundbreaking Blue Eden project in Swansea will generate 320 MW of energy, create 2,500 jobs and support another 16,000 in the supply chain. It was interesting to hear about the potential of the blue energy island, which is a small way to make a real difference.
In Merseyside yesterday, metro Mayor Steve Rotheram signed a deal with the South Korean state-owned water company, which owns and operates the world’s largest tidal range scheme, to develop the Mersey tidal power project, which could generate enough energy to power 1 million homes. It will create thousands of jobs and help the region get to net zero by 2040.
In Cumbria, where the Government are about to give the go-ahead to a new coalmine—I thought we might have had the news by now—there is the potential for thousands of jobs in green industries such as offshore wind, tidal power and green hydrogen. The choice facing us is whether we doggedly rely on dirty fossil fuels—hon. Members mentioned the investment allowances being put into new fossil fuel exploration instead of supporting renewables—or embrace the green industries of the future and the potential for jobs. The right hon. Member for Orkney and Shetland said that 80% of the content is UK-generated, which will have a great impact on the supply chain. It is a no-brainer that there should be Government backing behind that.
In my local area, the Western Gateway group of local authorities has set up a new commission to explore tidal options for the Severn. The hon. Member for Gloucester (Richard Graham) knows that that has been an ongoing discussion ever since we have been in Parliament. Talks stalled in the early years of the coalition Government. There was a feasibility study. There were concerns about the cost, and talk about whether a barrage or tidal lagoons would be the better option.
There were also valid concerns about the impact on the natural environment in the estuary. We have not touched on that much today, because people are so excited about the potential of tidal power, but we have to look at some of the possible negatives. In the case of the Severn, there were concerns about the impact on migrating bird life at the wonderful wetlands at Slimbridge, for example. Environmental campaigners have also expressed concerns about the Morecambe bay project.
I hope we can find a way through this and harness the potential of the Severn, which has the second-highest tidal range in the world, but we need to do so in an environmentally sensitive way. More generally, we need to look at preventing sea life from being caught in the blades of the turbines and to assess the impact of vibrations and noise on marine mammals that echolocate to communicate and navigate, such as whales and dolphins. Such things need to be taken into account.
I recognise that the costs of tidal stream are far higher at the moment than those of solar and wind, but they have fallen significantly in recent years and are expected to fall further still. The comparison was made with Hinkley Point C. As the right hon. Member for Orkney and Shetland said, it is not about setting one off against the other and saying either/or; it is about making that comparison. If we are investing in Hinkley Point C, we should be looking at renewable options. It is estimated that, by 2035, tidal stream could provide power at £78 per MWh, which could fall to £50 per MWh by 2047 —quite a few Members have mentioned those statistics.
Alan Brown
The hon. Lady says it is not an either/or, but the reality is that if too much money is invested in nuclear, its generation capacity means that there is not enough scope for renewables coming on to the grid, so in some cases it is an either/or.
Kerry McCarthy
The hon. Gentleman answered his own question earlier by flagging up the investment allowances attached to the windfall tax that are being given to the fossil fuel companies. That money should be directed towards this investment and not towards fossil fuels. It is not money for nuclear versus money for renewables; it is money for fossil fuels versus money for clean energy sources.
We have talked about the UK having the potential to develop around 1 GW of tidal stream by 2035 and up to 11.5 GW by 2050. National Grid’s future energy scenario models up to 3% of UK electricity demand being met by marine renewables by 2050, but we need to do more to release that potential. According to Energy Monitor, 14 GW of planned UK power capacity has been cancelled, is dormant or is stuck in the early stages of development but, as has been said, lack of investment and of a clear sense of direction are not the only barriers.
The grid has been talked about—it is a massive issue—and we have heard about the Welsh Affairs Committee report. The same issues come up time and again when I talk to people as part of my shadow role: long waits—sometimes of up to 10 years—to connect clean power sources to the grid, delays to projects and investors being deterred.
Wera Hobhouse
Will the hon. Lady give way briefly?
Kerry McCarthy
I am conscious of the fact that the Chair said I have only 10 minutes. I am already nine minutes in, so I think I need to crack on. I want to hear what the Minister has to say about what we are doing to sort out the problems with the grid. I am sure he is well aware of them.
We also need action across the board to simplify and streamline the planning system, not in the way proposed by the previous, short-lived Administration, who were all about scrapping vital environmental protections and riding roughshod over the wishes of local communities, but by ensuring we do not place unnecessary burdens on renewable energy developers that delay or even derail new projects.
Other Members have mentioned the UK Marine Energy Council’s suggestions for speeding up approval for tidal stream projects—for example, reducing baseline surveys, decreasing the regulatory review from nine months to three and so on. I look forward to hearing what the Minister has to say about that.
We hear good things from around the country—for example, what the Labour-led authority in Merseyside is doing. Labour has made a plea for certainty and clarity from the Government, and I hope the Minister is looking at what Labour has said about the drive for a clean power system by 2030, a national wealth fund and establishing Great British Energy to help give investors that certainty. GB Energy would have a remit to invest in marine and tidal power to harness the huge potential of this island nation. We would support new marine energy projects, and we need to see something similar from the Government that would give people a signal that those projects are very much on the radar, rather than coalmines and fossil fuel exploration.
