Mersey Tidal Power
A unique opportunity to harness the power of our greatest natural assets to deliver a cleaner, greener, more prosperous future for our children. It's time for tidal.
Tackling the climate emergency is a global challenge that we can no longer afford to ignore.
Our young people have laid down a challenge to our nation’s leaders to save the planet. I am determined that in our region we will do all that we can to rise to that challenge. It’s about changing our behaviours. That doesn’t just mean cutting back and stopping what we do, but embracing new opportunities and technologies.
The River Mersey has been the lifeblood of our fortunes for centuries. I believe it holds the key to our future success too.
In our region, we have both the technological capability and the political will to be leaders of the Green Industrial Revolution and become Britain’s Renewable Energy Coast.
Developing our Mersey Tidal Power Project could mean generating enough power for up to 1 million homes, create thousands of local jobs, and our city region becoming a worldwide centre of excellence in a vital industry of the future.
I think that we have a unique opportunity to harness the power of our greatest natural assets – our river and our people – to deliver a cleaner, greener, more prosperous future for our children.
Our team of global experts, based right here in the Liverpool City Region, has examined the case for tidal power. They have determined that there is a strong strategic case for taking forward a Mersey Tidal Power project and are developing detailed plans for how it could be made a reality. I also believe there is a strong moral case for it too – our planet’s future depends on it.
There is still a huge amount of work to do but I can’t wait to get to work. With the right support, we could be generating clean, renewable power by the end of the decade, growing our local economy and safeguarding the future of our planet for generations to come.
The River Mersey, our greatest natural asset, can play a vital role in tackling the climate emergency and helping our transition to green energy while boosting our future prosperity and the UK’s energy security.
With its huge tidal range, a tidal power scheme on the Mersey could produce enough clean, green electricity to power every home in the city region for more than a hundred years, while creating thousands of jobs.
Complementing existing strengths in offshore wind and solar energy, this predictable and proven energy source could be key to the city region’s ambition to be net zero by 2040.
With the right support, we could build the world’s largest tidal power scheme right here, at the heart of the Liverpool City Region.
The Liverpool City Region has one of the UK’s largest tidal ranges and a long history of research into tidal power. We have a unique opportunity to harness this heritage and the power of our tides to generate a plentiful, reliable supply of clean, green energy for generations to come.
Existing strengths in wind, hydrogen and solar photovoltaic power, along with developments in clean transport, mean that we are already leading the way in developing a new, cleaner and greener economy. Delivering the Mersey Tidal Power Project would create thousands of jobs, with new skills, in the green economy. A game changer for Liverpool City Region and beyond.
Onshore and offshore wind, solar photovoltaic and nuclear power alone cannot fulfil the UK’s demand for electricity, with a doubling in demand for electricity from new technologies predicted by 2050. Low carbon technologies such as nuclear and carbon capture and storage also have significant challenges to overcome.
As we move away from fossil fuels, a diverse mix of generation is critical. Intermittency of the major renewable sources such as wind and solar power makes it hard to match supply with demand.
Tidal energy is predictable, flexible and reliable. It is a no-regrets, well established technology with minimal decommissioning needs and, alongside other renewables, tidal power can help ensure we have power – when we need it
The idea of harnessing the tidal power of the River Mersey is not new. The first plans for a tidal barrage across the Mersey were produced back in 1924, with, reports and studies dating back to the 1980s. Operational tidal power schemes, like La Rance in France, date back as far as 1966.
The climate emergency, and improvements in turbine technology, mean that tidal power’s time has come.
The project is currently in Phase 3 Concept Development which is looking to better understand how a barrage and/or lagoon project can fit in River Mersey and Liverpool Bay. We are continuing to develop our understanding of our river and coastal environment, what a scheme would look like, and how we can balance the benefit of a renewable marine energy scheme into the natural environment.
As we strive for Net Zero, both regionally and nationally, then projects like a tidal range energy scheme will be important to increase the mix of renewable generation in the UK and reduce our reliance on oversea energy supply.
Global and local environmental considerations are at the heart of the project. We believe that the global climate emergency means we have a moral duty to pursue opportunities such as the Mersey Tidal Power Project. Local environmental considerations are also central to its development. We have already successfully deployed clean power technologies such as offshore wind in sensitive marine environments. Marine modelling has demonstrated the lower environmental impacts of new turbine technology with two-way generation and pumping. There is much scope for further mitigation through dialogue with environmental stakeholders as the project progresses.
