Plans Progress To Build World’s Largest Tidal Scheme On The Banks Of The River Mersey
The title of this post, is the same as that of this press release from the Liverpool City Region.
These four bullet points, act as sub-headings.
- Mersey Tidal Power has the potential to become the world’s largest tidal scheme
- Formal planning process for UK’s “first of a kind” Mersey Tidal Power set to begin
- Potential to manage environmental issues associated with climate change
- Scheme would need government backing to complete development stage
These three paragraphs introduce the project.
Advanced proposals to build the world’s largest tidal scheme on the banks of the River Mersey have been unveiled by the Liverpool City Region’s Mayor Steve Rotheram.
Mayor Rotheram has revealed that the city region will pursue a barrage between the Wirral and Liverpool as the preferred option for the city region’s flagship Mersey Tidal Power project.
The barrage scheme – the “first of a kind” in the UK – could generate clean, predictable energy for 120 years and create thousands of jobs in its construction and operation.
Note.
- This page on the Liverpool City Region, has this explanatory video.
- This brochure can also be downloaded.
At a first glance all the documentation is very professional.
These are my thoughts.
How Much Power Will The Mersey Tidal Project Generate?
This graphic from the brochure shows electricity generation in Liverpool Bay.
Note.
- The dark blue circles are the thirteen existing wind farms, that have a total capacity of 3 GW.
- The yellow circles are four new wind farms, that will be built by 2030 and will have a total capacity of 4 GW.
- The Mersey Tidal Project will have 28 x 25 MW turbines and generate 700 MW.
I also suspect that the power generation will be supplemented by a large battery, that will smooth out the electricity, when the wind isn’t blowing and the tides are at the wrong cycle.
Access For Ships To The Tranmere Oil Terminal And The Manchester Ship Canal
This article on the Liverpool Business News is entitled £6bn ‘Barrage Across The Mersey’ Takes Step Forward.
This is the introductory paragraph.
Steve Rotheram says his £6bn Mersey Tidal Power project will see a barrage across the river, with locks to allow ships through, but original 2030 switch-on now looks unlikely.
The article has a picture which could show locks on the Wirral side of the Mersey.
This Google Map shows the location of the Tranmere Oil Terminal and the Manchester Ship Canal.
Note.
- Birkenhead is in the North-West corner of the map.
- The line of white squares running parallel to the River Mersey, indicate the stations of the Wirral Line to Chester and Ellesmere Port.
- The Tranmere Oil Terminal is indicated by the red arrow at the top of the map.
This second Google Map expands the area on the West bank of the Mersey, at the bottom of the map.
These are Eastham Locks, which allow ships to enter and leave the Manchester Ship Canal.
This third Google Map shows the area around the Tranmere Oil Terminal.
As before the Tranmere Oil Terminal is indicated by the red arrow, with Cammell Laird to the North.
The Liverpool Business News article says this about oil tankers, that use the Mersey.
In terms of oil tankers alone, there are more than 700 vessels coming in and out of the Mersey every year. Supertankers berth at the Tranmere Oil Terminal next to the Cammell Laird shipyard and around 500 smaller vessels berth at Stanlow at Ellesmere Port.
LBN understands that some form of lock system will be incorporated into the barrage to allow ships in and out. That might prove tricky for supertankers which suggests the barrage would be down river from the Tranmere terminal.
This Google Map shows the Manchester Ship Canal as it goes East from Eastham Locks.
Note.
- The Manchester Ship Canal clings to the South Bank of the Mersey.
- The red arrow indicates Stanlow Refinery,
- There is a lot of industry on the South Bank of the Manchester Ship Canal.
It would appear that access to the Manchester Ship Canal gives access to several important places other than Manchester.
Access To Garston Docks
This Google Map shows the Liverpool Bank of the Mersey.
Note.
- The blue marker in the North-West corner of the map indicates the Royal Albert Dock.
- Garston Docks are in the South-East corner of the map
- There are no docks between Liverpool and Garston and much of the route can be walked along the Mersey.
- On the other bank of the Mersey, note the green ship at the Tranmere Oil Terminal, that can be seen in other maps.
This second Google Map shows Garston Docks.
Note.
- There are three docks.
- The Garston Channel and the Old Garston River provide a route for ships to enter or leave the docks.
The Wikipedia entry for the Port of Garston, indicates that the port is rather run-down and a shadow of its former self.
It would appear that ships would have to pass through the locks in the barrier, which would likely be on the Wirral bank, to gain access to the Manchester Ship Canal and then cross the Mersey for Garston.
However, the barrier is built, it must have a route to both the Tranmere Oil Terminal and the Manchester Ship Canal at Eastham Locks.
The barrier could be built either North or South of the Tranmere Oil Terminal.
- If built North of the oil terminal, the locks in the barrier will have to accommodate the largest supertanker that calls at the terminal.
- If built South of the oil terminal, the locks in the barrier would only have to accommodate the largest ship that needed to use the Manchester Ship Canal or visit Garston.
One option would probably be more affordable.
Barrage Cross The Mersey
The very informative Liverpool Business News article, explains why a barrage was chosen, in this paragraph.
After pondering whether to build a barrage across the river from Liverpool to Wirral, or a floating lagoon, the Combined Authority has chosen the former as it would be cheaper and also creates a bridge that could have a pedestrian and cycle link.
The choice of a barrage sounds sensible on grounds of cost and accessibility.
British Gas Joins Forces With Samsung To Help Customers Power Smarter Energy Use
The title of this post, is the same as that of this press release from Centrica.
This is the sub-heading.
British Gas and Samsung have today announced the exciting first step in a long-term venture – aimed at helping customers better manage their energy use and increase the adoption of low carbon heating technologies in homes across Britain.
These are the first two paragraphs.
The collaboration will see British Gas integrate with Samsung’s SmartThings app to help customers optimise their home appliances to use energy when the cost and demand are lower. This is now possible through the integration of SmartThings Energy and British Gas’ PeakSave demand flexibility scheme informing customers (by sending notifications via their smartphone, TV or other compatible devices) of the best times to use household appliances to save money.
The PeakSave scheme includes PeakSave Sundays, running every Sunday until the end of February with half-price electricity from 11am to 4pm for British Gas customers and PeakSave Winter events which encourages customers to move their electricity use out of peak times when there is high demand on Britain’s energy grid.
As a Graduate Control Engineer, I believe that this could make optimising your energy use much easier.
- It would surely be a lot easier to check usage on your phone rather than a smart meter, when you perhaps cook a ready meal, so that you can see if your microwave or traditional cooker is cheapest.
- Suppose you and everybody, who lives with you are out for supper and British Gas want to cut off your gas for a reward, you can make an appropriate decision.
- Hopefully, if you have the right controls, you’ll be able to switch lights and appliances off and on.
The possibilities are endless.
I shall certainly be looking at the reviews of this app.
There is a section in the press release called Scaling Up Low Carbon Heating Opportunities, where this is said.
The collaboration will also help support customers in their journey to decarbonising their homes by introducing smart technologies in a way that is simple and empowering. From early 2024, British Gas will include Samsung heat pumps in its offering to British households to support the UK’s commitment to reach net zero by 2050.
The venture will see specially trained British Gas surveyors and engineers working with consumers to explain the benefits of heat pumps and then conducting the installations on-site. Samsung will be supporting workforce training as part of their efforts to upskill the heating industry to ensure there are enough installers to service the expected growing demand.
British Gas also offers customers the chance to purchase heat pumps through flexible financing methods. This, combined with the recently increased UK Government Boiler Upgrade Scheme grant of £7,500, creates an attractive package of financing options to help people make the transition more affordable.
Various plumbers, who I would trust, have given me different views about heat pumps.
I suspect the Samsung’s SmartThings app might be able to simulate your energy usage with or without the heat pump, as it would know your energy use with your current boiler.
I was doing similar calculations for chemical plants in the early 1970s at ICI, using a PACE 231-R computer.
Consider.
- It may look rather old fashioned, but it could solve a hundred simultaneous differential equations in one go.
- Two similar computers linked together were the analogue half of NASA’s moon mission simulator.
- Without these wonderful machines, NASA would not have been able to re-calculate the dynamics of Apollo 13 and the mission would be remembered as a disaster, rather than the first space rescue.
The average current smart phone has more computing power than a PACE 231-R.
What’s In It For Samsung?
I have a Samsung television, but unfortunately it has a screen fault because of age. So if I had the Samsung app and liked it, I might buy another Samsung TV.
Similarly, the app might give me a financial reason to buy a Samsung heat pump.
Samsung will sell more equipment.
What’s In It For Centrica?
Centrica would appear to be a loser, as bills will fall and they could be paying customers to not use energy.
But they are surely hoping that their market share will increase and I’m sure Samsung will give them a commission.
What’s In It For The Consumer?
Hopefully, they’ll get lower energy bills.
But also they might get a lot of convenience controlling their appliances and heating.
Conclusion
Using energy is becoming a computer game with monetary rewards.
Is the deal between Centrica/British Gas and Samsung another deal that has been brought to fruition by the Korean President’s visit to the UK?
It looks like this is the third recent deal signed between UK and Korean companies, after these two.
- South Korea, UK Strenghten Offshore Wind Ties
- UK And South Korea Help Secure Millions For World’s Largest Monopile Factory
I suspect, there might be a few more deals, if Charles and Camilla really turned on the charm.
In Mersey Tidal Project And Where It Is Up To Now, I wrote about talks between Liverpool City Council and Korea Water about a tidal barrage of the Mersey. This project must surely be a possibility!
This is said in the Wikipedia entry for Korean Air under Fleet Plans.
At the Association of Asia Pacific Airlines Assembly in 2018, Korean Air announced that it was considering a new large widebody aircraft order to replace older Airbus A330, Boeing 747-400, Boeing 777-200ER and Boeing 777-300. Types under consideration for replacement of older widebody aircraft in the fleet include the Boeing 777X and Airbus A350 XWB. At the International Air Transport Association Annual General Meeting (IATA AGM) in Seoul, Chairman Walter Cho said Korean Air’s widebody order is imminent and it is considering an extra order of Airbus A220 Family including developing version, Airbus A220-500.
Note.
- Airbus A350 XWB have Welsh wings and Rolls-Royce engines.
- Airbus A220-500 are made in Canada with wings and composite parts from Belfast. Rolls-Royce may have a suitable engine.
Could a deal have something in it for the UK?
Although Korea has its own SMR program, I wonder, if there could be a link-up between Korean industry and Rolls-Royce over SMRs?
Carlton Power Secures Planning Consent For World’s Largest Battery Energy Storage Scheme
The title of this post, is the same as that of this news story from Carlton Power.
This is the sub-heading.
£750m 1GW Battery Project To Be Built At Carlton Power’s Trafford Low Carbon Energy Park In Greater Manchester
These three paragraphs outline the project.
Carlton Power, the UK independent energy infrastructure development company, has secured planning permission for the world’s largest battery energy storage scheme (BESS), a 1GW (1040MW / 2080MWh) project located at the Trafford Low Carbon Energy Park in Greater Manchester. The £750m BESS scheme will strengthen the security and resilience of the energy system in the North West of England, and support the energy transition and the growth of renewable power generation in the region.
Planning permission for the BESS was granted by Trafford Council, the local planning authority.
Subject to a final investment decision, construction of the battery storage scheme is expected to begin in the first quarter of next year (2024) with it entering commercial operation in the final quarter of 2025. Carlton Power is in advanced talks with companies to finance, build and operate the Trafford BESS.
I have a few thoughts.
It’s A Monster
This Wikipedia entry, lists the World’s Largest Grid Batteries.
- The current largest is Vistra Moss Landing battery in the United States, which has a capacity of 1600 MWh and an output of 400 MW.
- The Trafford BESS will have a capacity of 2080 MWh and an output of 1040 MW.
By both measures the Trafford BESS is larger.
Where Will It Get The Energy?
Consider.
- In Liverpool and Morecambe Bays there is over 5 GW of offshore wind farms either operational, under construction or planned.
- Carrington gas-fired power station has a capacity of 884 MW.
- The Western HVDC Link is a 2250 MW link between Scotland and Connah’s Quay in North Wales.
- I wrote about the proposed Mersey Barrage in Mersey Tidal Project And Where It Is Up To Now.
I can see enough renewable energy being generated to replace Carrington gas-fired power station.
Who Will Finance, Build And Operate The Trafford BESS?
There are two major Energy Storage Funds in the UK.
- Gore Street with 27 projects totalling 1.17 GW.
- Gresham House with 17 projects totalling 425 MW.
Note.
- There are other smaller funds.
- The figures given are cumulative outputs for the portfolios.
- Sourcing the large number of batteries might be a problem.
- As the maths of these batteries are now well-known, I would expect that finance shouldn’t be too much of a problem.
- Local companies like Liverpool Victoria or Peel Holdings could even take a position.
A large American contractor backed by US money could swallow the whole project.
That happened with North Sea oil and gas in the last century.
Is Highview Power’s CRYOBattery Still Planned?
Carlton Power’s news story says this about Highview Power’s plans.
In addition to Carlton Power’s two projects, Highview Power Storage Inc. is planning to build and operate the world’s first commercial liquid air storage system – a £250m 250MWh long duration, cryogenic energy storage system – on the Trafford Low Carbon Energy Park, which was until 1991 the site of the Carrington coal-fired power station. The Low Carbon Energy Park is located close to Manchester Ship Canal and the £750m Carrington flexible gas-fired power station which entered operation in 2016.
It seems that the CRYOBattery is still planned.
Conclusion
Manchester is getting a powerful zero-carbon hub.
Mersey Tidal Project And Where It Is Up To Now
The title of this post, is the same as that of this article on the Liverpool Echo.
This is the sub-heading.
With a major agreement on the project reached this week, we take a look at what it all means.
There is a section, which is called So What Is A Mersey Tidal Project?, where this is said.
The idea is to build a huge damn structure in the River Mersey with turbines that can harness energy from the tides of the river and convert it into clean power. The city region combined authority is hopeful that this could power up to 1 million homes and create thousands of local jobs
The city region has one of the country’s largest tidal ranges so it is seen as a perfect opportunity to explore a tidal project here. It is hoped such a project could generate a ‘plentiful, reliable supply of clean, green energy for generations to come.
In the 1970s, I did a small project management consultancy at Frederick Snow and Partners in London. They showed me their ambitious plans for a Severn Barrage, which was a tidal scheme, that would have created a tenth of our electricity and would have cost around a billion pounds.
But Harold Wilson, who was Prime Minister at the time, felt that the money would be better spent on building massive coal-fired power stations, rather than building a clean power station, that would last centuries.
A second section is called What Happened This Week?, where this is said.
This week the Liverpool City Region signed an agreement with the company behind the current world’s current largest tidal project with a view to learning lessons.
The Sihwa Lake tidal range power plant, which is operated by Korea Water Resources Corporation, generates 552GWh of clean, green energy every year, replacing the equivalent of 862,000 barrels of oil a year.
Jeong Kyeong Yun, Vice President of Korea Water Resources Corporation, known as K-water, was in Liverpool this week to sign an historic Memorandum of Agreement with Mayor Rotheram. It is hoped the agreement will pave the way for close co-operation between the two tidal power projects, through reciprocal visits and information sharing.
Note.
- The Liverpool Echo is still making spelling mistakes, like damn instead of dam. In the 1960s, Fritz Spiegl used to give us all pleasure by writing about them.
- 552 GWh would keep the UK powered up for nearly a month.
- The Sihwa Lake Tidal Power Station has a comprehensive Wikipedia entry.
- The Sihwa dam has a road over the top.
- Unlike Frederick Snow’s scheme for the Severn, Sihwa only generates power, on the incoming tide. But it does generate 254 MW.
As ever, Liverpool is thinking big and getting the experience from those, who know what they are doing.
This last paragraph, gives the thoughts of the Mayor.
Mayor Rotheram said that with the right support, he hopes the project could be generating clean, renewable power by the end of this decade.
I would go along with that.
The Mersey Tidal Project And The Mersey Gateway Bridge
Frederick Snow’s plans for the Severn could have incorporated a new road and rail crossing of the estuary.
This Google Map shows the the Sihwa Lake Tidal power station.
The road over the dam is clearly visible.
I took these pictures of the Mersey Estuary as I came back from Liverpool on Tuesday.
This Google Map shows the Mersey Estuary.
Note.
- The River Mersey flowing from the North-East corner of the map to the South-West corner.
- On the South Bank of the Mersey, there is the deep-water channel of the Manchester Ship Canal.
- The bridge in the North-East corner of the map is the Mersey Gateway Bridge.
- Then there is the pair of bridges at Runcorn; the Silver Jubilee Bridge and the Runcorn Railway Bridge.
I am fairly sure, that the Mersey Tidal Project would be built downstream of the pair of bridges at Runcorn.
This Google Map shows the Mersey Estuary from the Runcorn Bridges to the mouth of the Manchester Ship Canal.
Note.
- The Mersey Gateway Bridge and the two Runcorn bridges are in the North-East corner.
- The route of the Manchester Ship Canal is clearly visible.
- Liverpool John Lennon Airport is on the North Bank of the Mersey.
- The M56 and M53 Motorways run East-West across the map to the South of the River.
This map leads me to the conclusion, that a tidal barrage with a road on top could link Liverpool to the M56.
I have some thoughts.
Rail Access To Liverpool
There is an electrified railway between Liverpool and Ellesmere Port.
- The railway can be picked out running across the bottom of the map.
- In Liverpool’s Vision For Rail, I talked about Liverpool City Region’s plan to expand this service to Helsby, Frodsham and Runcorn East.
- Helsby and Frodsham are shown on the map.
I wouldn’t be surprised to see a new Park-and-Ride station, where the M56 and the railway cross.
Ship Access To Manchester And Other Ports
Barrages usually have to provide access for ships to pass through to any ports behind the barrage.
But the Mersey Tidal Project already has that access. – It was built in the 1893 and is called the Manchester Ship Canal.
There is probably strong protection between the Mersey and the Canal between the mouth of the Canal and Runcorn, which may impact positively on the costs of the barrage.
The Simple Barrage
Sihwa Lake Tidal power station is a simple barrage with a bridge over the power station in the middle.
This Google Map shows the location of the power station.
Note.
- Seoul is in the North-East corner of the map.
- The Sihwa Lake Tidal power station is marked by the red arrow.
This Google Map shows a close-up of the power station.
Note.
- The ten turbines appear to be in the gap.
- There appears to be a road on top of the barrage.
- The area to the West of the power station is marked as a rest area.
- A Moon Observatory is marked.
- It has bus stops, showing that it is served by the 123 and 123-1 buses.
It is an impressive structure.
I’m sure that this type of barrage would work over the Mersey.
- A road could be built on top.
- It may only be able to generate electricity,from an incoming tide, like Sihwa.
- It could incorporate a rest area.
I do suspect though Liverpudlians would add a few unique touches of their own. Perhaps some liver birds or superlambananas.
The Frederick Snow Solution
The Severn is a wide river and he proposed that there would be a dam across the river, with a spine running East along the middle of the river.
- The spine would divide the river into two lakes.
- On the incoming tide, sluices would open and allow water to flow into the Northern or high lake from the Mersey estuary.
- On the outgoing tide, sluices would open and allow water to flow out of the Southern or low lake into the Mersey estuary.
- Water would flow between the high and low lake through turbines to generate electricity.
- I have assumed that the high lake is on the North side, but if the geography is more suitable, the high and low lakes could be reversed.
In the design for the Severn Barrage, an International airport would have been built on the spine.
But Liverpool already has a nearby International airport, so perhaps it could be much better to install a large electrolyser and hydrogen storage on the spine.
