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.
Ørsted Signs Two ‘Industry First’ Monopile Contracts For Hornsea 3 Foundations
The title of this post, is the same as that of this press release from Ørsted.
This is the introductory paragraph.
Ørsted, the world’s most sustainable energy company, has signed two ‘industry first’ contracts for the fabrication of XXL monopile foundations for the Hornsea 3 offshore wind farm.
I have a few thoughts about the press release.
XXL Monopile Foundations
These four paragraphs describe Hornsea 3’s XXL monopile foundations.
Subject to Ørsted taking a Final Investment Decision on Hornsea 3, the contracts have been finalised with Haizea Wind Group, through its subsidiary Haizea Bilbao, and SeAH Wind Limited, a UK-based subsidiary of SeAH Steel Holdings (SeAH).
Ørsted will be the first major customer at SeAH Wind’s new monopile facility in Teesside, and the agreement with Haizea marks the company’s first XXL monopile contract with Ørsted.
The deal with SeAH represents the single largest offshore wind foundations contract secured by any UK company. Haizea’s agreement is the largest single contract ever secured by Haizea Wind Group.
Each of the huge foundation structures for Hornsea 3 will weigh between 1,300 and 2,400 tonnes and measure in at between 83 and 111 metres in length. Monopile production is expected to start in 2024.
Note
- These are huge steel structures.
- But then the water depth appears to be between 36 and 73 metres.
- It looks like the orders are shared between Spanish and Korean companies
This article on offshoreWIND.biz, is entitled Beyond XXL – Slim Monopiles For Deep-Water Wind Farms.
These are some points from the article.
- XXL-Monopiles have been successfully used for water depths of up to 40 metres. Now wind farm developers need monopiles “beyond XXL”.
- The extension of the range is needed, mainly to enable the use of larger turbines, deeper water, and harsher environmental situations.
- These monopiles will allow turbines of up to 15 megawatts with rotor diameters of up to 230 metres.
- This monopile design automatically induces the idea of design and fabrication optimisation to ensure that monopiles continue to lead the ranking of most economical foundation systems.
In the 1970s, I was involved with a Cambridge University spin-out company called Balaena Structures, who were using similar much larger structures to support oil and gas production platforms.
I was just doing calculations, but I do wonder if these XXL monopile foundations, owe things in their design to work done by structural engineers, like those I met at Cambridge fifty years ago.
Another Aussie Green Hydrogen Hub In The Works As Total Eren Eyes 1GW Darwin Project
The title of this post, is the same as that of this article on Recharge.
These two paragraphs introduce the project.
Developer Total Eren is sizing up the potential for a 1GW green hydrogen project in Australia’s Northern Territory (NT), taking the total capacity of green H2 projects under development in the state to 13.8GW.
A Memorandum of Understanding (MoU), signed between Total Eren and the NT state government on Monday, will see the two work together to progress the project, dubbed the Darwin H2 Hub.
This paragraph gives a few numbers.
Plans for the scheme comprise more than 2GW of solar PV generation, which will power a 1GW electrolyser. The project aims to produce 80,000 tonnes of hydrogen a year, equivalent to around 4% of the 1.96 million tonnes of green H2 South Korea expects to import from overseas by 2030.
Note.
- Australia seems to be the place to develop large hydrogen and energy projects.
- South Korea will beat a path to your door, if you have the capacity to create millions of tonnes of green hydrogen.
The article finishes with a good summary of the future prospects of Australia’s green hydrogen industry.
I believe that Australia could become a world superpower, as it will certainly provide zero-carbon power to a good proportion of South East Asia.
South Korea Is On The Hunt For An Overseas Hydrogen Production Location
The title of this post, is the same as that of this article on Hydrogen Fuel News.
It is an interesting article, which talks about how both South Korea and Japan are looking to source hydrogen from another country and how Australia is in prime position.
This Wikipedia entry, which is entitled Energy In South Korea, has this breakdown of electricity production in South Korea.
- Thermal – 65.3%
- Nuclear – 31.1%
- Hydro – 1.6%
- Other – 2%
Note that at the time of writing the UK is producing 39.0% of electricity from renewables and 15.9% from low-carbon sources.
Consider.
- As South Korea imports a lot of liquified natural gas and has no oil or gas resources of its own, importing hydrogen is just replacing a carbon-dioxide producing fuel with a zero-carbon one, that is produced from renewables.
- Other than Australia, other possible sources of hydrogen mentioned include Saudi Arabia and the United States, but is their hydrogen produced from renewables or steam-reforming of methane?
- I suspect another could be South Africa, as they can develop a lot of wind power around the Cape.
I think we’ll see more countries going down the same route as Japan and South Korea and importing large quantities of hydrogen.
- Countries with lots of renewables like geothermal, hydro, solar and wind will benefit.
- Countries with plenty of gas can use steam-reforming to create hydrogen.
But surely, the biggest beneficiaries will be world-class companies, like ITM Power in Rotherham, who build electrolysers.
History Goes Round In Circles
I have just read this article on the BBC web site entitled Balloons take tech war to North Korea.
This is the first paragraph.
Some anti-North Korean activists firmly believe the best way to defeat Kim Jong-un’s regime is to break the cycle of propaganda served up every day to those living north of the border.
It got me thinking about the origins of printing with moveable type.
In some ways it was the Internet of its day, as suddenly information and books became available to anybody who could read.
My father always said that printing started to break the power of the church, as now you didn’t need a priest or monk to read the bible or learned books.
So are the balloons taking their CDs and information to North Korea, just another manifestation of everybody’s insatiable search for the truth? Let’s hope they are as successful in breaking the power of the evil regime in North Korea, as printing was in breaking the power of the Church.
My Christmas Presents To My Son And His Partner
They usually like me to give them gift vouchers, for somewhere like Liberty or Selfridges, so they can choose something for themselves or their home, which has just be renovated.
To complicate matters my son’s partner is Korean, so I couldn’t be over-the-top in a way only the English would understand.
The frames were simple ones from John Lewis and the translation was courtesy of Google’s English to Korean translator.
It was totally correct. Isn’t the Internet a wonderful thing?
Who would have thought that this idiot, who had trouble getting O levels in French and English, would be able to get a translation into Korean right?
What Not To Wear In The Korean Demilitarised Zone
Ian Mcmillan, the Barnsley Poet, is usually entertaining. Today, on BBC Breakfast, he talked about his visit to the Korean Demilitarised Zone.
For his visit, he was told, he mustn’t wear tight trousers or a low top! The second may make it easier for a sniper to get a heart shot!
But why the first?
The Incredible Lee-Duck Hee
On the tennis this afternoon, they were talking about a Korean junior tennis player, who played in the Boys Singles at Wimbledon. There is a report here.
Lee-Duck Hee is completely deaf.
I’m reminded of a story told me by a friend, who went to boarding school. His school had a good football team, but the one they never beat, was a school for the deaf.
Another Urban Fox Attack
There is a report of another fox attack on a baby. Happily, it doesn’t seem to be too serious and not outside the capabilities of the NHS.
One of my friends is Korean and I asked him, if they get these sort of problems in Seoul. he said that they don’t and he felt, there was many wild animals in the city except for rats and mice. This is confirmed by this post from a blog.
But how many other cities in other countries have urban animals, that aren’t always cuddly?
This is a story about wildlife in Berlin.
So it’s not just a British problem!
Eton’s Gangnam Style
Students at Eton College have created a viral hit based on Psy’s Gangnam Style. The Guardian says it’s a bit cringe-worthy in this piece, but surely it shows that the power of the Internet is there for us all to harness.
