Thirdly, we need to speed up the consent process, and I welcome the decisions taken by the Department for Energy Security and Net Zero in that regard. Stakeholders have expressed their dismay to me that, although Canada can secure consent and start construction within two years and France can do similar within three, the process can take up to a decade in the UK. I am concerned that if the timescales cannot improve, we will fritter away our competitive advantage not just with marine renewables but across a large number of established and innovative technologies. I appreciate that consenting is devolved to Scotland; the Minister knows that I have raised the unacceptably long process for consent decisions with the Energy Consents Unit and Marine Scotland, and I would welcome an update on the recent discussions he has had with Scottish Ministers on consenting.

As the Member for South Devon, I am proud to represent a constituency with a long and rich history of maritime activity. From the bustling port of Brixham to the naval port of Dartmouth, the sea is very much part of our identity. It is for that reason that I am here today in firm support of the development of marine renewable energy. However, progress must be pursued in a way that respects and supports our fishing industry, ensuring that these two vital sectors can thrive side by side.

The UK is a global leader in renewable energy, and marine renewables present a unique opportunity to further that leadership. The water surrounding our islands hold enormous potential. Living on wet, windy islands, would it not be great if we could put some of that weather to good use?

According to the Offshore Renewable Energy Catapult, tidal stream energy could provide up to 11.5 GW of capacity —following what my right hon. Friend the Member for Orkney and Shetland said, I think that figure is probably more now—which is equivalent to approximately 15% or more of the UK’s current electricity demand. Wave energy, though less mature technologically, offers additional capacity for long-term energy generation. These technologies, which include tidal stream turbines and oscillating wave surge converters, are capable of harnessing predictable and consistent energy, which is a crucial advantage over more intermittent renewable sources, like solar and wind.

As we pursue this promising future, we must not lose sight of the vital role that our fishing industry plays. Brixham, one of the UK’s most productive fishing ports, landed a record breaking £43.6 million-worth of seafood last year. That is not just an economic statistic—it represents the hard work of the fishing community and their contribution to our food security. As we navigate the transition to renewable energy, it is essential that the voices of our fishermen are heard and their expertise is valued.

Marine renewable energy projects must be carefully planned to avoid disrupting fishing grounds and marine ecosystems. That requires advanced spatial planning tools, such as geographic information systems, to identify suitable sites for development that minimise conflict with established fishing zones and sensitive habitats. Consultation with the fishing community must be a fundamental part of the development process, not an afterthought. Fishermen know the waters better than anyone and can provide invaluable insights into where installations can co-exist happily with fishing activities. With good collaboration, we can ensure that marine renewables are located in areas that minimise conflict and maximise benefit.

This approach is not just a matter of fairness. It is also a matter of practicality. Energy security and food security are two sides of the same coin. As we strive to achieve net zero and reduce our reliance on fossil fuels, we must also ensure that we are protecting our ability to feed the nation. The sea can provide both energy and food, but only if we manage it wisely and sustainably. It is worth noting that the development of marine renewables can also enhance marine biodiversity if designed thoughtfully, creating artificial reefs and habitats that benefit marine life.

I must, though, express some concern about the lack of clear Governmental targets for marine renewables. Neither the previous Government nor the current Government have set—yet—any specific targets for the installation of wave or tidal energy. Although the Government have committed to achieving at least 95% low carbon generation by 2030, the December 2024 clean power action plan fails to set explicit goals for marine renewables. Instead, it relegates them to a potential long-term role in decarbonisation objectives.

I believe that lack of ambition is a missed opportunity to capitalise on the UK’s vast marine resources and risks leaving us behind in the global race for renewable energy innovation. As an island nation, where the one thing we can rely on is the tide coming in and going out day after day, we should be doing more to capitalise on it. That seems more logical than shipping in solar energy from Morocco—although if we could ship in sunshine from Morocco, I would be up for that. I urge the Government to rectify the oversight by setting binding targets for the deployment of wave and tidal energy. Doing so would provide clarity and confidence for investors and developers, fostering rapid growth in this critical sector. Moreover, it would align marine renewables with the broader decarbonisation agenda, ensuring that they contribute meaningfully to our energy transition. I also call on the Government to provide long-term funding for research and development, such as the UK’s £20 million ringfenced budget for tidal stream innovation, and streamline the regulatory process to accelerate deployment. The Government must create a supportive framework for private investment, through mechanisms such as contracts for difference, to ensure market confidence, with a ringfenced budget for tidal and wave. The Government must also commit to robust engagement with the fishing industry to ensure that livelihoods are not sacrificed in the name of progress. There is room for everyone in this endeavour, but only if we take the time to plan and act responsibly.

Marine renewable energy offers a bright and sustainable future for our coastal communities and the nation as a whole, so let us seize this brilliant opportunity but do so with care, collaboration and respect for all those who depend on the sea.

I welcome the Government’s recent clean power action plan, which recognised the potential for tidal stream and floating offshore wind to be important components of long-term decarbonisation in the UK. However, for that to happen—and if marine renewables are to follow a similar cost-reduction pathway to solar and fixed offshore wind—the marine renewables industry does need Government support.

I cannot stand here and talk about renewable energy in the sea without mentioning floating offshore wind, so I will reiterate some of the asks that that industry would have as well to kick-start floating offshore wind, particularly in the Celtic sea. Like tidal and wave energy, floating offshore wind needs a ringfenced element in the AR6. The one-size-fits-all route is disadvantaging the Celtic sea due to the comparative lack of port infrastructure, skills and wider supply chain support. We are a virgin area; unlike Scotland, we have not had oil and gas before, so we are starting from scratch.

I have a big interest in this subject. Since I became an MP, way back in 2010, I have always been aware that Strangford lough, which is in the constituency I represent, has the potential for tidal green energy provision. There was a pilot scheme so many years ago. That was probably the wrong time, simply because the energy generated was too expensive. Things have moved on, and what was not possible way back then is possible now. That is why I wanted to speak on this issue.

The deployment in Strangford lough is the company’s first in the United Kingdom of Great Britain and Northern Ireland. It is part of the deployment of the X-flow project, which is led by Queen’s University. The project includes Applied Renewables Research and the Shell Technology marine renewable programme as industry partners, and is supported by the green innovation challenge fund. That fund is led by the Centre for Advanced Sustainable Energy, and is delivered in partnership—again, partnership is how it all works—with the Department of Enterprise, Trade and Employment at the Northern Ireland Assembly. That is another initiative that I pushed in my time as an Assembly Member, but more so as an MP here, working in conjunction with the Assembly back home.

Support for the marine renewables industry demonstrates not just awareness of our developing energy system up to 2030, but foresight into how we achieve energy security in the long term. Julian Leslie, the chief engineer at the National Energy System Operator—the body responsible for advising the Government on their clean power strategy—has described the 2030 clean power target as reaching the base camp of Mount Everest. He describes the next stage, decarbonising heat and wider industry on the way to 2050, as climbing to the mountain’s peak. What that means is that the next generation of technologies, such as tidal stream and wave energy, will need to develop and proliferate deployment at scale as our economy becomes increasingly reliant on electricity.

I also highlight the work of Offshore Renewable Energy Catapult’s marine energy team, which focuses on tidal stream and is, I am proud to say, based in my constituency of Camborne and Redruth, and in Hayle. As has been mentioned, according to the Marine Energy Council tidal stream technology can meet over 10% of UK electricity demand, with the UK leading in the planned installation of over 130 MW in its seas by 2029. We must show support for the commercial development of such marine renewable projects through greater funding from Great British Energy, as my hon. Friend the Member for Edinburgh North and Leith (Tracy Gilbert) mentioned, and by ringfencing contracts for difference funding in AR7 later this year.

In the 20th century, the UK’s power system was dominated by coal; in the 1990s, that system evolved into the “dash for gas”. We are now pivoting towards the use of offshore and onshore wind, partnered with flexible and low-carbon dispatchable power. Generations before us in the last century would scarcely have been able to imagine what our energy system looks like now. However, I believe marine renewables represent immense potential, which we must support today to achieve the net zero goal of tomorrow.

Many people do not support renewables. I guess they are not here today but we occasionally hear them in the Chamber, saying things like, “What are you going to do when the wind doesn’t blow and the sun doesn’t shine?” We see the answer when we look out to the sea: the tide rises and falls twice a day, every day, 365 days a year, so we can build a future on renewable energy. We must do that if we are to achieve net zero and protect our planet.

I would like to support the points that have been made on the need for a taskforce, which would certainly be important and should encompass skills, training and research in the whole offshore energy sector, and I urge the Government to recognise the regional powerhouse that the south-west can be and is in renewable energy. We have six energy NSIP DCOs—development consent orders for nationally significant infrastructure projects —across Devon, Somerset and Wiltshire, for example. It is a vital part of the UK economy, and Taunton lies right at the heart of it.

With a wind-lashed coastline stretching for a grand total of 1,680 miles, Wales has an abundance of marine energy potential. This growing sector already contributes significant sums to the Welsh economy. Last financial year, the marine renewable energy sector delivered £29.9 million to the Welsh economy, and it currently sustains 429 full-time jobs. We would like the number of jobs to be way more than that, please.

I want to touch on the contracts for difference auction process and EU innovation funding. To date, the marine renewables industry has been set at £20 million, £10 million and £15 million ringfenced in the last three auctions. If we want to build a renewable energy industry with high levels of UK content, the level needs to be set—as the lead Member for this debate, the right hon. Member for Orkney and Shetland, has said—at £50 million for tidal stream and £5 million for wave. I am very supportive of that for this year’s renewable auction. Marine Energy Wales says that without this ringfence, Welsh tidal projects will be disadvantaged, stalling momentum and undermining the benefits already delivered by sites like Morlais.

In 2010, when the current Secretary of State for Energy Security and Net Zero was Secretary of State for the then Department of Energy and Climate Change, he announced funding for investigations of embryonic tidal technologies. Rolls-Royce and Atkins won the contract to do the study, and their work showed that a tidal scheme on the Aberthaw to Minehead route would generate per year 30.4 TW hours of electricity, significantly more than the Cardiff to Weston-super-Mare line, which was in the region of 20 TW hours per annum.

I thank my hon. Friend for making an excellent point about the centrality of Somerset—in particular, the Minehead route just north of Taunton—to renewable energy. Does he accept that tidal range and tidal barrages and lagoons could make a significant contribution? As he pointed out so well, Swansea lagoon would have done up to 30 TWh, but we could do that across the UK. There could be tidal lagoons in Morecambe bay and in Cumbria, where one was proposed. That would bring investment to regions across the UK and not just benefit the south-west and Somerset.

14:47 Claire Young (Liberal Democrat)

It is a pleasure to serve under your chairship, Ms Jardine. I congratulate my right hon. Friend the Member for Orkney and Shetland (Mr Carmichael) on securing this important debate and on his efforts to keep this issue on the agenda in Parliament. I want to reinforce the point he made about the Crown Estate Commission. As Liberal Democrats, we believe in working with communities to deliver change. The Crown Estate may own the seabed, but that does not mean the commission should be allowed to ignore the needs of others who make their living from the sea, whether through fishing, tourism or any other means. That point was picked up by a number of Members, particularly my hon. Friend the Member for South Devon (Caroline Voaden), who spoke up powerfully for the fishing industry in Brixham. The commission should also not be exempt from the duty to protect nature that other public bodies have, recognising—as we do—that the nature and climate emergencies go hand in hand.

On the wider issue, marine renewables will help us to meet our commitment to tackle the climate crisis—the single biggest challenge facing our generation.

My hon. Friend and I are members of the Energy Security and Net Zero Committee, and yesterday we heard evidence from the Secretary of State. He said that the transition to net zero is the biggest opportunity for all of us, including those in the south-west, to create prosperity and the jobs we need for the future. Does my hon. Friend agree?

Sadly, we are living in the shadow of the Conservatives’ failure to fully invest in renewable energy and to properly insulate our homes. The previous Conservative Government rowed back on their pledges to meet net zero and shamefully watered down policies aimed at reducing our carbon emissions. That means we need bold action now to put us back on the right course. Liberal Democrats want to see this Government step up to the plate and provide a comprehensive energy strategy designed to bring down bills, end fuel poverty, cut greenhouse gas emissions and deliver energy security.

A key part of that strategy must be marine renewable energy. I welcome the initial progress being made, with a 50% uplift in ringfenced funding support for tidal stream energy as part of the contracts for difference renewables auctions. With a significant stretch of the Severn estuary coastline in my constituency, I am keen to see the UK leading the world in tidal power. My hon. Friends the Members for Taunton and Wellington (Gideon Amos) and for Melksham and Devizes (Brian Mathew) highlighted the opportunities in the wider south-west. Given that it is his birthday, I will not argue with my hon. Friend the Member for Taunton and Wellington today about his plans to make Taunton the centre of that enterprise. The 50% uplift is a good first step and shows that we are beginning to take the sector seriously.

However, there is so much more potential out there, if only the Government would reach out and grasp it. My right hon. Friend the Member for Orkney and Shetland mentioned the parallels with the gas and oil industry, and I would like to look at wind power as an example of how these things can be done. When my right hon. Friend the Member for Kingston and Surbiton (Ed Davey) was Secretary of State for Energy and Climate Change, he made it his key priority to back renewables and managed to push through a bold climate agenda that embraced new technologies. That quadrupled the UK’s level of renewable power and made us a world leader in offshore wind energy.

The Office for National Statistics has stated that employment estimates within the low-carbon and renewable energy economy are at record levels. Because of the willingness to back British renewables, the industry is now worth an estimated £69.4 billion to the UK economy and supports thousands of jobs. The economic benefits and the need to make sure they are kept in the UK have been highlighted by many Members, including the hon. Members for Edinburgh North and Leith (Tracy Gilbert), for Truro and Falmouth (Jayne Kirkham) and for Camborne and Redruth (Perran Moon).

The Government talk a lot about their drive for economic growth, and I suggest that that goes hand in hand with investing in renewable power generation. Putting a just transition front and centre allows us to not only reskill those already working in the energy industry, but upskill people to give them new opportunities around our coast. Our coastal areas have long felt left behind and forgotten about, as I know from talking to people in places such as Severn Beach in my constituency. Those areas now have the potential to become booming hubs of activity, which is why Liberal Democrats want to see marine renewables used as part of a plan to invest in them, with a dedicated skills fund to provide green skills and jobs to communities.

Addressing the climate crisis is about embracing opportunity and empowering communities to make the most of their surroundings. It is time that the UK stepped up as a world leader in this area, so I hope the Minister will agree to listen to our proposals, which will benefit the marine renewables sector greatly.

Sadly, there was no mention of tidal in the “Clean Power 2030” document published by the Government. There is a perception—it might not be the reality—that tidal technology has fallen through the gap. In the rush to decarbonise the energy system, the Secretary of State seems to be putting all the eggs into two baskets. It would be good if the Minister could set out that that was not the case and that the Government were as committed to tidal and wave power as they should be. When the wind does not blow and the sun does not shine, wind and solar will not keep the lights on in the United Kingdom.

The previous Government looked at the Swansea tidal lagoon in great detail and depth, but the decision was taken before my time in the Department for Energy Security and Net Zero not to proceed with it. I am informed that it was due to a combination of the cost and the reluctance of those involved to make the case that the technology would be successful. However, if it can be presented as a viable project—if the costs can be brought down and the technology can be proved to work—of course the current Government could look at it again. We should be investing in things that work and that return a benefit to the taxpayer.

15:03 Michael Shanks (Labour)

Clean power by 2030 is not some ideological project, as the shadow Minister, the hon. Member for West Aberdeenshire and Kincardine (Andrew Bowie), and others in the Conservative party might like to suggest. It is a critical pathway for how we deliver energy security in the long term; all our constituents have been facing a considerable cost of living crisis as a result of us not having home-grown energy security. The clean power mission is about ensuring that we not only have that energy security but tackle the climate crisis and deliver economic growth. I make no apologies for the fact that we are a Government moving at pace, because it is important that we grasp the opportunities for the implementation of both marine technologies and the many other innovative technologies that Britain can be a world leader in delivering. It is also our best opportunity to deliver cheaper energy for people across the country.

I thank everybody who has attended. For the benefit of the Backbench Business Committee, who may run the rule over these things, we have had no fewer than 17 Members in the Chamber in the course of this debate, covering the length and breadth of the country. The hon. Member for Truro and Falmouth (Jayne Kirkham) said there was unity in the message; it was almost as if we had been briefed in these matters. This allows me to place on record my appreciation—shared by all who are engaged in this issue, I am sure—of the work of the UK Marine Energy Council, RenewableUK, Scottish Renewables, and in particular, the companies that get the devices in the water. Their commitment and dedication to decarbonisation and the development of this most important sector is nothing short of inspirational. I extend my gratitude to them and everyone who has contributed today.
