Will Norwegian Pumped Storage Hydro Help Us Through The Winter?
In UK To Norway Sub-Sea Green Power Cable Operational, I discussed the North Sea Link interconnector to Norway.
The North Sea Link is no ordinary interconnector, as it is a lot more than a 1.4 GW cable linking the electricity grids of the UK and Norway.
- At the UK end, there is an increasing amount of wind power. The UK has added 3.5 GW in 2022.
- At the Norway end, there is the 2.1 GW Ulla-Førre hydropower complex.
- The water to generate electricity at Ulla-Førre comes from the artificial Lake Blåsjø, which contains enough water to generate 7.8 TWh of electricity.
- The storage capacity at Ulla-Førre is 857 times greater than that at the UK’s largest pumped storage hydroelectric power station at Dinorwig in North Wales.
- The power complex consists of five power stations and some can also be used as a pump powered by UK electricity to fill Lake Blåsjø with water.
Effectively, the North Sea Link, the Ulla-Førre power complex and Lake Blåsjø are a giant pumped storage hydro battery, that can either be filled by Norwegian precipitation and water flows or by using surplus UK electricity, through the North Sea Link, which opened a year ago.
If the Norwegian precipitation goes on strike, the only way to fill Lake Blåsjø is to use surplus UK power, which I suspect will be British wind and nuclear in the middle of the night!
But then I thought we will be short of electricity this winter.
- I suspect we will be at times, but then at others there will be a surplus.
- So the surplus will be pumped to Norway to top up the reservoir at Lake Blåsjø.
- When we are short of electricity, the Norwegians will turn water back into electricity and send it back through the North Sea Link.
It will be more sophisticated than that, but basically, I believe it provides us with the electricity we need, at the times, when we need it.
I wouldn’t be surprised to be told, that we’ve been squirreling away overnight wind energy to Norway over the last few months.
I have written more about Ulla-Førre in The Monster In The Mountains That Could Save Europe’s Winter.
It includes a video about the building of the complex.
The Belgians Go Large
This press release from Elia Group is entitled Elia Presents Its Plans For An Energy Island, Which Will Be Called The Princess Elisabeth Island.
These two paragraphs outline the project.
In the presence of federal ministers Tinne Van der Straeten (Energy) and Vincent Van Quickenborne (North Sea), system operator Elia has presented its draft plans for what will be the world’s first artificial energy island.
The Princess Elisabeth Island will be located almost 45 km off the Belgian coast and will serve as the link between the offshore wind farms in the second offshore wind zone (which will have a maximum capacity of 3.5 GW) and its onshore high-voltage grid. The energy island will also be the first building block of a European offshore electricity grid that will serve as a central hub for new interconnectors with the UK and Denmark. The island is an innovative tour de force that once again puts Belgium on the map as a pioneer in offshore energy.
Note, that Princess Elisabeth is the heir apparent to the Belgian throne.
I have some thoughts.
Will The Wind Turbines Float Or Have Fixed Foundations?
Consider.
- 3.5 GW of wind farms will probably need around 220 wind turbines.
- Most of the large wind farms in the seas around the UK, that are below about 50 miles from the shore are on fixed foundations.
- The seas around East Anglia and Belgium are probably fairly similar.
I suspect that using today’s technology, the turbines will have fixed foundations.
But floats with two or more turbines , that generate more electricity per square kilometre may be developed.
Will Hydrogen Be Generated On The Island?
This could happen and I don’t see why not.
Tankers could even dock on the island to transport the hydrogen.
Could The Island Service Floating Wind Turbines?
All that is needed, is sufficient depth of water and a large crane.
It is a possibility!
Will There Be A UK Interconnector To Princess Elisabeth Island?
The press release says this.
The energy island will also be the first building block of a European offshore electricity grid that will serve as a central hub for new interconnectors with the UK and Denmark.
There could be interconnectors all over the North Sea linking wind farms and energy islands to the UK, France, Belgium, The Netherlands, Germany, Denmark and Norway.
We’d all be in it together.
Conclusion
This is a very ambitious project.
Interior Lights On Victoria Line Trains
After looking at the lighting on the Bakerloo Line trains, before and after the fitting of LEDs in Seeing London Underground’s Bakerloo Line Trains In A New Light, I thought it would be useful to look at other lines.
These pictures show the 2009 Stock trains of the Victoria Line.
They look like florescent tubes to me.
I am surprised that these trains which are less than fifteen years old, don’t have LED lights.
I very much suspect though, that if the Bakerloo Line LED lights are an undoubted success, that the Victoria Line trains will be updated.
How To Kill Flies
I am being plagued by flies at the moment and no matter how many squirts I give with fly spray, they keep on coming.
I found this remedy on the Good Housekeeping web site and it is very simple.
All that is needed, is some cider apple vinegar, some washing up liquid and some glasses.
These pictures show the method.
I made four and distributed them around my house.
They seem to work, as after an hour or so, they had collected hundreds of flies.
Rolls-Royce And SOWITEC Cooperate On Power-To-X Projects
The title of this post, is the same of that of this press release from Rolls-Royce.
The press release starts with these two bullet points.
- Target: up to 500 MW electrolysis capacity for power-to-X projects
- Production of green hydrogen and e-fuels for shipping, aviation, mining, agriculture, data centers
In Rolls-Royce Makes Duisburg Container Terminal Climate Neutral With MTU Hydrogen Technology, I wrote how Rolls-Royce were building a carbon-neutral energy supply for the port.
This Rolls-Royce graphic illustrates the project.
It looks like SOWITEC would be the sort of company to install the decentralised renewables for this project.
Rolls-Royce seem to be collecting the technology to build complex projects like the power supply for the Duisburg Container Terminal, either by acquisition or negotiating friendly links.
But I do think, that Rolls-Royce possibly need two items for a complete portfolio.
A factory with a large capacity to build electrolysers. The press release says they need 500 MW by 2028 or nearly 100 MW per year.
Some form of GWh-sized energy storage. I wouldn’t be surprised to see Rolls-Royce do a deal with an energy storage company.
Florescent Lights On The Circle Line
These pictures show a selection of florescent lights on the Circle Line.
The pictures were taken at Monument and Temple stations.
In Seeing London Underground’s Bakerloo Line Trains In A New Light, I talked about fitting LED lighting on Bakerloo Line trains.
As LED replacements for florescent tubes seem to exist, are these tubes up for replacement?
LED Lighting In The New Parts Of Bank Station
These pictures show the lights in the new parts of Bank station.
Note.
- They would appear to be LED downlighters, as I can see a distinct matrix.
- One light appears to have died.
The older parts of the station, including the Northbound Northern Line platform still have fluorescent strip lighting.
New Escalators At Bank Station Between The Northern Line And The DLR
This picture shows the triple-barrelled escalator that runs between the Northern Line and the Docklands Light Railway.
Note.
- The digital clock was showing the right time.
- There are three escalators.
- Peering over the barrier, it looked to be that construction has almost finished.
This visualisation shows the station.
Where was I standing when I took the picture?
The label at the top right says.
New entrance to Bank station on Cannon Street. Lifts and triple escalators to Northern Line and DLR.
The triple escalator leading down from the Cannon Street entrance to the Northern Line level is clearly visible.
- It looks like passengers can go between the bottom of the escalators and both the Northbound and Southbound platforms of the Northern Line, using the cross-passage shown.
- I suspect that the triple escalators to and from the DLR in-line with the escalators to the entrance.
- Lifts would probably serve all three levels.
It is an intricate design, that looks like it minimises conflicting passenger routes, at the Cannon Street or Southern end of the station.
Move towards the North and you can see the moving walkway in a new tunnel parallel to the two Northern Line tracks, which connects to the Central Line.
At its Southern end, there is a spacious plaza.
- It has two cross passages to the two Northern Line platforms.
- It is a short walk to the moving walkway to and from the Central Line
- It appears that on the Southern side, is the triple-escalator leading down to the DLR.
These pictures show this plaza and the connecting tunnels and escalators.
Note.
- The entrance to the tunnel with the moving walkway is opposite the escalators to the DLR.
- There are two cross-tunnels connecting the two Northern Line platforms and the plaza.
- All tunnels are wide.
It looks like pedestrian routes are as follows.
Cannon Street Entrance And Northern Line
The large three-barrel escalator between the Cannon Street and Northern levels.
Cannon Street Entrance And Docklands Light Railway
The large three-barrel escalator between the Cannon Street and Northern levels and a shorter escalator between the Northern and DLR levels.
Cannon Street Entrance And Central Line
The large three-barrel escalator between the Cannon Street and Northern levels, a walk to the moving walkway and the escalators to the Central Line.
Cannon Street Entrance And Waterloo And City Line
I suspect, this will use the new route to the DLR and then the existing route between the DLR and the Waterloo and City Line.
Northern Line And Central Line
The moving walkway and the escalators to the Central Line.
Northern Line And Docklands Light Railway
It looks like there are two-banks of three escalators between the Northern and DLR levels.
Northern Line And Waterloo And City Line
Not sure of this route, but it could be via the DLR.
Central Line And Docklands Light Railway
Via the moving walkway and escalators at both ends.
Central Line And Waterloo And City Line
As now?
Docklands Light Railway And Waterloo And City Line
As now?
Conclusion
It would be an ideal location for a chase thriller!
I can’t wait until it opens.
But I do believe that the moving walkway should be extended under the roads to Moorgate station.
Two Oases In The City
I came across these oases in Temple Avenue in the City of London.
What a good idea! The notice says it’s part of a Covid-19 Street Recovery Scheme
Painting Blackfriars Bridge
It looks like Blackfriars Bridge is being repainted.
It certainly looks like it needs a repaint.
