Britain Is Building The World's Largest Tidal Power Project

A green energy project taking place in Britain right now is the Merseyside Tidal Power Project. Once completed this mega project will power 1 million homes in Liverpool. What is the insane engineering behind the Mersey Tidal Power project, why are they building it and will the Mersey Tidal Power project be a success?

Is this actually a feasible solution for Merseyside?

[@terryhoath1983]

1. Britain is NOT, I repeat NOT "Building The World's Largest Tidal Power Project" That is a downright clickbait lie. 2. The West Coast of England does NOT, repeat NOT have 4 tides a day. It has one tide every 12 hours and 25 minutes. Southampton has 4 tides a day because of the 2 tides a day up and down the English Channel washing around the Isle of Wight first from one side and then a couple of hours later from the other side. Rotterdam in the Netherlands also has 4 tides a day the alternate one are little more than a bounce in the middle of the low tide. Antwerp, just down the Coast has only 2 tides a day 3. 0.28 There is no such place as "Merseyside Town". It is an artificial administrative district of a regional authority. 4. Although the lower lying areas of places that you have named may be liable to flooding large areas of the Sefton administative district, the Wirral, Runcorn and Widnes are close to or above 50 ft above sea level and much of these places is above 100 ft above sea level. 5. Why at 0.57 are you showing an animation of a tidal streaming school project ..... and then go on and talk about barrages ? 6. "As far as the River Mersey goes" HAAAR HAAR hahaha ! The River Mersey rises nearly a thousand feet up in the Pennines. It follows a fairly tortuous course. From a height of a little over 40 ft above sea level, it tumbles over a weir into the Manchester Ship Canal south-east of Irlam. You have Irlam shown on your map at 2.24 towards the right-hand side. A little further West, it falls out of the otherside of the Manchester Ship Canal. The Canal at that point is about 35 ft above sea level . The Mersey tumbles over two weirs in Warrington and only at that point does it become tidal. By that point the tidal range is only a few feet. 7. You talk about protection from flooding and then you go on about tidal lagoons. Tidal lagoons are a bloody silly idea and will do NOTHING to prevent flooding. 8. 5.52. Your ridiculous piece of animation seems to show water flowing >> 9. If what you mean by "around the hour" a totally ridiculous expression, you mean "continuously" it shows that you know nothing about tides. At each change of tide there is what is called "slack tide". Hardly any water moves during slack tide. There is also about half an hour either side as the speed of flow diminishes to nothing and then after slack tide takes time to build up again. Turbines that will deal with a 3-4 ft head are quite different to tidal streaming turbines. Tidal streaming turbines will do nothing for flood protection.You appear to be talking about barrage turbines which will produce next to nothing as the head diminishes and then picks up again.The very best that could be expected is power for about 5 hours per 6 hour 12.5 min falling tide and the same on the rising tide. Maximum power will only be produced in the middle 4 hours. Some neap tides at Liverpool are only 12 feet and will only produce about a third of the electricity of a good spring tide with a longer dead period than on spring tides. 10 You also don't understand about tidal range. The tidal range of "up to 10 metres" is only experienced at Liverpool Pier Head. As the water enters the wider back estuary,that range diminishes somewhat. Also, heights above sea level are taken from the mean or mid-tide so a 32 ft tidal range means 16 ft above mean tide dropping back to 16 ft below mean tide. In short, this video is a load of clickbait DRIVEL.

[@margaretjones777]

It's debatable and even doubtful for a number of reasons. 1) The built up areas along the Mersey (and much of the Merseyside coast) are more hilly than you might expect, and so are at little risk of flooding - indeed, they haven't been flooded at any time. In reality, the UK is gradually tilting towards the east, so the sea is actually retreating along much of the west coast - something that is very apparent along Dee Estuary (in Merseyside). 2) There is still a lot of commercial maritime activity within the Mersey, including several docks, two ferry terminals, a major ship-builder, a busy marina and one of the UK's largest oil refineries, all of which would be impeded by any barrage. Yes, you could build additional lock gates, but this would still leave these businesses at a competitive disadvantage. Any barrage could easily spell the death of (for example) Cammell Laird, one of the biggest employers in the region. 3) The Mersey contains a huge amount of silt that would rapidly build up behind any barrage, and so would require continuous dredging. It's not like the hard, rocky shore of (say) Brittany, in which barrages can operate with only modest maintenance. Indeed, the reduced flow within the Mersey caused by any barrage would almost certainly necessitate additional dredging to keep the Port of Liverpool (one of the UK's largest) open. 4) Perhaps surprisingly, the mudflats of the Mersey are an important wildlife area, especially for migrating birds, so any barrage would be fiercely resisted on environmental grounds. 5) The existing infrastructure on Merseyside (especially the roads and railways) is configured in such a way that any barrage would need to be a considerable distance upstream, which would obviously reduce the amount of electricity that could be generated. This is not to say that a barrage shouldn't be considered, but it's unlikely that it would achieve a satisfactory cost/benefit ratio.

Salt water is a known problem with many solutions.

[@garrettmillard525]

That's wrong. The French barrage mentioned above did absolutely experience issues when it was created half a century ago, but the use of cathodic protection (sacrificial cathodes, the same thing used in your water heater at home) basically eliminates this issue while only using a small % of the plants power production. As well as use of plastic piping instead of steel. The copper-nickel-aluminum alloy components they used are also basically immune to sea-water corrosion.

[@carelgoodheir692]

@@markjones4704 Interestingly no-one (apart from a smaller Soviet scheme) has copied the French. That suggests there are serious problems with damming inlets. At the time the Skye Bridge got built there was an alternative proposal to dam the straights at Kylerhea and at Kyleakin. The Kylerhea dam would have had the tidal generators, the Kyleakin dam would have carried the road to Skye and perhaps a railway extension. It would have had lock gates to allow ships into Loch Duich. But, the amount that would have been generated would not have justified the costs, the environmental drawbacks and the inconvenience to ships and road traffic involved. There are trials going on in the Pentland Firth, to install turbines on the sea bottom turned by the tides. That may prove a better way of harvesting tidal power. Then other straights off Scotland's westr coast could get them too and between them there would be continuous supply - slack water comes at different times up the west of Britain.

As an ex-Liverpudlian, projects like these have been proposed many times. Although it could provide solutions to two problems, energy and tidal flood defence, as you say, many hurdles lie in the way. Upstream of Liverpool, there are salt marshes, feeding grounds for sea birds. These could be lost. Where do you place it to allow shipping, nearer the mouth with lock gates to provide an deep water harbour, or little further upstream, after the entrance to the Manchester Ship Canal and save the cost of large lock gates. Many issues to resolve but great to see that it is being thought of again.

Liverpool is in the midlands, which is not sinking. It's the south that is sinking because of the rebound effect of melting ice caps from c15'000 years ago.

The principle of most projects where production is involved and sales of the item produced at a profit are involved is called “an investment” as opposed to “a cost”. These large projects are generally funded by private money and not tax-payers money. Subsequently massive numbers of jobs and related support services are also often created and this in turn keeps local unemployment to a minimum. Subsequent financial benefit to local authorities is always an important feature of most successful business plans. Suitable improvements to local infrastructure such as better road networks, improved medical facilities, schools and support services, (mainly also funded by the private investors money) are therefore often shown to be a likely and positive legacy to the local community should the proposed project receive final approval.

Tidal power will be huge, however building barriers like shown here is not the answer. It's why it hasn't taken off before. There's plenty of power under the water for slow turning powerful turbines. Water is over 800 times denser than air. The ones that will succeed will have a nature covered (for aesthetics) cement pier type line surrounding long lines of turbines along the middle and/or most potent currents of the major tidal rivers and waterways (NOT across them) surrounding them so as to both protect them and to pull the up for service and cleaning when needed. The pier will be surrounded with pull-up (for regular cleaning) strong wire mesh fencing to keep marine life out and negate any marine biologist objections. In this fashion, ships and marine life can go around it on each sides untouched and unaffected.

[@philspencelayh5464]

Two problems come to mind, 1st a barrage would probably prevent navigation of the river, not so much these days, 2nd and biggest problem the Government has pretty much screwed the economy and can't even afford to give doctors a decent wage so the cash would have to come from elsewhere.

The Mersey Ship Canal means that ships don't need to sail in the River Mersey.

@@MassiveChetBakerFanCruise ships dock all year round, ferries to Belfast and the Isle of Man also dock.

The biggest concern is whether they can build these without the Chinese getting involved. Apparently there will be debt from the funding, and I would hate to see Britain paying China for labor or equipment costs.

London is sinking because of isostatic rebound, not because of climate. R

‘Merseyside town’ that famous place.

[@701983]

The depicting of continuous constant tidal power is wrong, since the tides don't switch from full rising tide to full falling tide within seconds. Actually, you only get a fraction of peak power on average. And there are times of absolutely no power (switch from rising to falling/falling to rising tide). The video mentioned 1.5 TWh per year, which equates to an average power of only 171 MW. Which would be only 14% of the mentioned 1.2 GW peak power. The big advantage over PV and wind power is predictability and reliability of fluctuating power, but not continuity (constant power).

[@701983]

But of course, if you interconnect a couple of tidal power plants of similar power, but with phase-shifted tides (some distance between them), you could get more or less continuous power.

Venice’s tidal wall has proved a DISASTER

Where is the sea level rising parkgate where king henry the 8th sailed into is now dry land plus other places and old photos show the water levels havnt risen i heard one side of england gains a bit of land and the other loses a bit food for thought.

[@andyhurrell]

Only three billion? HS2 is looking increasingly like an expensive white elephant.

[@johnevans6399]

If it gets built within the Liverpool area it will probably get pinched.

[@Sam-lm4ef]

Merseyside town???

[@user-qi4qi4pm6h]

The Mersey Barrage has been discussed for many decades. Most recently since the 1970s.

[@Teasehirt]

Go, Liverpool !!!!

[@aaronohara34]

0:55 My guy did not just use this clip when talking about Widnes and Warrington 😂. Much easier on the eyes mind you.

[@synthmaker]

Very interesting video but the loud background music makes it very hard for me to enjoy it.

There's one in France on the Rance and its been generating for 50 years

[@H4N5O1O]

0:54 mercy side LMAO.

[@kendavis5686]

What do I know, but this looks nuts to me since the problem is (just like London) not the sea so much as the sea plus the extreme rain storms that global warming will bring i.e the water coming down the river is as dangerous as the sea.

[@simplyed9482]

Air filled drums and pulleys are the ticket. Less infastructure and more energy

[@BIGJATPSU]

Just building them on the sea floor would suffice for the power generation and still allow, mostly, unrestricted port access. As for the holding back THE OCEAN... short term it could work, long term is to much upkeep. The Dutch are the masters at it, but projecting forward, gonna cost them A LOT! It's not so much man losing to nature, just nature never loses to man given enough time.

[@carelgoodheir692]

The Dutch rijkswaterstaat (sp?) is an immense organisation, both in funding and in how many it employs. It is well aware of the problems approaching with sea levels rising.

[@magsb3]

There could be a toll road put on top to help with the finances.

[@fastfreddy19641]

Great idea but the current tory government is not big on supporting green energy

It could happen if there is an authority strong enough to get Peel Holdings to allow it.

[@user-wl4cl1ph3b]

This will not stop flooding as land in front of the barrier will bear the brunt of rising sea levels a perfect example is the Thames barrier when its raised all the lower level land further downstream ends up flooded

[@joependleton6293]

Of course, "people down stream" will be greatful ! Great historical city of their's.

[@lucylane7397]

There is no one down stream

[@MrMassivefavour]

I wonder if the electricity for the people will be free? Maybe they should ask the people of the city to pay through their local taxes with the deal being free electricity for 20 years

[@alancrowe6417]

We were told in cumbria in the 1950s that it would be vertualy free once they built Calder hall/Winscales/Selafield, didn't happen!

[@griswald7156]

Shropshire was a sea in prehistoric times….staffordshire will have a seaport soon.
