Brown Seaweed Could Remove 550 Million Tons Of Carbon
The title of this post, is the same as that of this article on the Carbon Herald.
This may seem like a story that has arrived a few months early.
But the report does come from the respect Max Planck Institute for Marine Microbiology.
The research is detailed on this page on their web site, which is entitled Slime For The Climate, Delivered By Brown Algae.
It is introduced by this sub-heading.
In form of fucoidan, brown algae could remove up to 550 million tons of carbon dioxide from the atmosphere every year.
Which is followed by this paragraph.
Brown algae take up large amounts of carbon dioxide from the air and release parts of the carbon contained therein back into the environment in mucous form. This mucus is hard to break down for other ocean inhabitants, thus the carbon is removed from the atmosphere for a long time, as researchers at the Max Planck Institute for Marine Microbiology in Bremen now show. They reveal that the algal mucus called fucoidan is particularly responsible for this carbon removal and estimate that brown algae could thus remove up to 550 million tons of carbon dioxide from the air every year – almost the amount of Germany’s entire annual greenhouse gas emissions.
Note that fucoidan has a Wikipedia entry.
The page says this about brown algae.
Brown algae are true wonder plants when it comes to absorbing carbon dioxide from the air.
It does seem to me that the Germans are on to something.
Raven SR And Chart Industries To Work Together On Hydrogen And CO2 Capture
The title of this post, is the same as that of this article on the Carbon Herald.
These are the first two paragraphs.
Renewable fuels company Raven SR and Chart Industries announced they have signed a Memorandum of Understanding to work together on the liquefaction, storage, and transportation of hydrogen as well as pure CO2 produced from Raven SR’s non-combustion Steam/CO2 Reformation process that converts waste to renewable fuel.
Raven SR uses local waste as feedstock to produce transportation-grade H2 and synthetic fuels, including sustainable aviation fuel (SAF). The carbon dioxide, which is a byproduct of the process, when liquefied is used for food and beverage production, fertilizer production, and other consumer needs and as a feedstock for concrete or alternative fuels.
Note.
- It appears like I do, that the companies feel it is better to use carbon dioxide, rather than store it.
- It also looks like they have improved the steam reforming process for making hydrogen.
- An advantage of the process is that it doesn’t need pure water.
There is a video in the article, which I suggest you watch.
It may be one of those processes that dies a premature and messy death, but my knowledge of catalysts and strange ways to produce gases like hydrogen and acetylene from working at ICI in the early 1970s, tells me that someone will develop a viable route to create hydrogen, that is better than the methods used today,
The Southern Entrance To London City Airport
I entered London City Airport by a different route today, taking these pictures as I walked.
Note.
- The route is level.
- It is on the Southern side of Hartmann Road, which is the main entrance road for the airport.
- There is a pedestrian tunnel under Hartmann Road into the airport.
- There are stairs and lifts into the Docklands Light Railway station at the airport.
- The lifts so all the way to the platforms of the DLR.
- The route is level from the lifts to the airport.
This Google Map shows the walk.
Note.
- I walked along the path, that runs NW-SE on the Northern side of the various courts and playgrounds.
- The entrance to the DLR station is at the South-East end of the path at the junction of Drew and Saville Roads.
This Google Map shows a 3D visualisation of the entrance.
Note.
- The path runs on the North side of the football pitch.
- The Southern entrance is to the right of blue play area.
- Drew Road runs across the entrance.
- It looks like there is a drop-off point for passengers, where the car is parked by the football pitch.
Would it be possible to create a waking route from this Southern entrance to a rebuilt Silvertown station on the Elizabeth Line?
This Google Map shows the area between the Southern entrance to the airport and the footbridge over the Elizabeth Line.
Note.
- The Southern entrance to the airport is in the North-East corner of the map.
- The footbridge over the Elizabeth Line is in the South-West corner of the map.
- The large building in the middle is Drew Primary School.
- Whytes Road, Saville Road and Leonard Street lead between the Southern entrance to the airport and the A112.
I took these pictures of the A112 and the footbridge a few days ago.
I think it would be possible to run a fleet of small electric shuttle buses on the route.
Elizabeth Line Trains From Silvertown Station
Currently, the following trains pass through the site of the original Silvertown station.
- Reading and Abbey Wood stopping at Twyford, Maidenhead, Taplow, Burnham, Slough, Langley, West Drayton, Hayes & Harlington, Southall, Ealing Broadway, Paddington, Bond Street, Tottenham Court Road, Farringdon, Liverpool Street, Whitechapel, Canary Wharf, Custom House and Woolwich.

- Heathrow Terminals 2 & 3 has a frequency of two tph and it has extra connections to Heathrow Terminal 4 and Heathrow Terminal 5.
The number of services will increase in May 2023.
Vestas 15 MW Prototype Turbine Produces First Power
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the introductory paragraph.
Vestas’ V236-15.0 MW prototype wind turbine has produced its first kWh after being fully assembled at the Østerild National test centre for large wind turbines in Western Jutland, Denmark.
The first of the four wind farms in the Hornsea wind farm complex to be developed is Hornsea One.
- It has a capacity of 1218 MW.
- It is comprised of 174 Siemens SWT-7.0-154, which each have a generating capacity of 7 MW.
If 15 MW turbines could have been used on Hornsea One, it would have more than doubled the generating capacity to 2625 MW.
But obviously, larger turbines have longer blades, so they may need to be placed further apart.
In Vattenfall Boosts Capacity For Norfolk Offshore Wind Zone, I write about how Vattenfall are increasing the size of their Norfolk wind farms, by proposing to use larger turbines.
Conclusion
Turbines will get larger and 15 MW turbines will be commonplace.
A possible advantage is that you only need sixty-seven turbines for a GW, as opposed to a hundred 10 MW turbines, so there are possibilities to optimise the most profitable way to build a wind farm.
Neptune Energy, Ørsted And Goal7 Explore Powering Integrated Energy Hubs With Offshore Wind
The title of this post, is the same as that of this press release from Neptune Energy.
These four paragraphs outline the agreement.
Neptune Energy today announced it has signed a Memorandum of Understanding with Ørsted and Goal7 to explore powering new integrated energy hubs in the UK North Sea with offshore wind-generated electricity.
Integrated energy hubs have the potential to combine multiple energy systems, including existing oil and gas production assets, carbon storage and hydrogen production facilities. They could extend the life of producing fields and support the economic case for electrification with renewable energy, to keep carbon emissions low.
The agreement will see the companies examine the potential to supply renewable electricity from Ørsted’s Hornsea offshore windfarm projects to power future Neptune-operated hubs in the UK North Sea.
Goal7 will provide project management support and technical input.
Note.
- Neptune Energy has three oil and gas fields in the UK North Sea; Cygnus (operational), Isabella (exploration) and Seagull (development)
- Gas from Cygnus comes ashore at the Bacton Gas Terminal.
- Ørsted owns the Hornsea wind farm, which when fully developed will have a capacity of around 6.5 GW.
- Cygnus and Hornsea could be not much further than 50 km apart.
- Seagull and Isabella are further to the North and East of Aberdeen.
- Ørsted has an interest in the Broadshore wind farm, which was numbered 8 in the ScotWind Leasing round.
These are my thoughts.
The Cygnus Gas Field And The Hornsea Wind Farm
This could be like one of those stories where boy meets the girl next door and they hit it off from the first day.
This page on the Neptune web site says this about the Cygnus gas field.
The biggest natural gas discovery in the southern North Sea in over 30 years is now the largest single producing gas field in the UK, typically exporting over 250 million standard cubic feet of gas daily. Cygnus contributes six per cent of UK gas demand, supplying energy to the equivalent of 1.5 million UK homes. It has a field life of over 20 years.
Two drilling centres target ten wells. Cygnus Alpha consists of three bridge-linked platforms: a wellhead drilling centre, a processing/utilities unit and living quarters/central control room. Cygnus Bravo, an unmanned satellite platform, is approximately seven kilometres northwest of Cygnus Alpha.
In 2022, we plan to drill two new production wells at Cygnus, with the first of these expected to come onstream in 4Q. The second well is due to be drilled in the fourth quarter and is expected onstream in the first quarter of 2023, with both wells helping to maintain production from the field and offset natural decline.
Gas is exported via a 55 km pipeline. Cygnus connects via the Esmond Transmission System (ETS) pipeline to the gas-treatment terminal at Bacton, Norfolk. Neptune Energy has a 25% minority interest in ETS.
Note.
- Cygnus with a twenty year life could be one of the ways that we bridge the gap until we have the two Cs (Hinckley Point and Sizewell) and a few tens of offshore wind gigawatts online.
- The two extra wells at Cygnus will help bridge the gap.
- The gas field has a pipeline to Bacton.
So what can the gas field and the wind farm, do for each other?
Hornsea Can Supply The Power Needs Of Cygnus
Typically, ten percent of the gas extracted from the wells connected to a gas platform, will be converted into electricity using one or more gas-turbine engines; which will then be used to power the platform.
So, if electricity from the Hornsea wind farm, is used to power the platform, there are two benefits.
- More gas will be sent through the pipeline to Bacton.
- Less carbon dioxide will be emitted in recovering the gas.
Effectively, electricity has been turned into gas.
Electricity Can Be Stored On The Sea-Bed
The Hornsea One wind farm has an area in the order of 150 square miles and it is only one wind farm of four, that make up the Hornsea wind farm.
I would argue that there is plenty of space between the turbines and the wells of the Cygnus gas field to install some form of zero-carbon underwater battery to store electricity.
But does this technology exist?
Not yet! But in UK Cleantech Consortium Awarded Funding For Energy Storage Technology Integrated With Floating Wind, I described a technique called Marine Pumped Hydro, which is being developed by the STORE Consortium.
- Energy is stored as pressurised water in 3D-printed hollow concrete spheres fitted with a hydraulic turbine and pump.
- The spheres sit on the sea-bed.
- This page on the STORE Consortium web site, describes the technology in detail.
- The technology is has all been used before, but not together.
I think it is excellent technology and the UK government has backed it with £150,000 of taxpayers’ money.
I also believe that Marine Pumped Hydro or something like it, could be the solution to the intermittency of wind farms.
Excess Electricity Can Be Converted Into Hydrogen
Any spare electricity from the wind farm can drive an electrolyser to convert it into hydrogen.
The electrolyser could be mounted on one of the Cygnus platforms, or it could even float.
The hydrogen produced would be blended with the gas and sent to Bacton.
Carbon Dioxide Can Be Stored In The Depleted Cygnus Gas Field
As the gas field empties of natural gas, the gas pipes to the Cygnus gas field can be reversed and used to bring carbon dioxide to the gas field to be stored.
The Cygnus gas field has gone full circle from providing gas to storing the same amount of carbon that the gas has produced in its use.
These are two paragraphs from the press release.
Neptune Energy’s Director of New Energy, Pierre Girard, said: “The development of integrated energy hubs is an important part of Neptune’s strategy to store more carbon than is emitted from our operations and the use of our sold products by 2030.
“Neptune has submitted three applications under the recent Carbon Dioxide Appraisal and Storage Licensing Round, and securing the licences would enable us to develop future proposals for integrated energy hubs in the UK North Sea.
I can envisage a large gas-fired power-station with carbon capture being built in Norfolk, which will do the following.
- Take a supply of natural gas from the Cygnus gas field via the Bacton gas terminal.
- Convert the hydrogen in the gas into electricity.
- Convert the carbon in the gas into carbon dioxide.
- Store the carbon dioxide in the Cygnus gas field via Bacton.
- I also suspect, that if a Norfolk farmer, manufacturer or entrepreneur has a use for thousands of tonnes of carbon dioxide, they would be welcomed with open arms.
Would the ultra-greens of this world, accept this power station as zero-carbon?
The Isabella And Seagull Gas Fields And The Broadshore Wind Farm
Could a similar set of projects be applied to the Isabella and Seagull gas fields, using the Broadshore wind farm?
I don’t see why not and they could work with the Peterhead power stations.
Stadler Presents Mock-Up Of Tram-Trains For German And Austrian Operators
The title of this post, is the same as that of this article on Railway Gazette.
This is the first paragraph.
A mock-up of the Citylink tram-trains that Stadler is to supply to operators in Karlsruhe, Saarbrücken, Neckar-Alb, Oberösterreich and Salzburg was unveiled at the Betriebshof West depot in Karlsruhe on December 13.
This is the most interesting paragraph.
‘Maximum standardisation and the fact that the order was shared between different operating companies reduces the costs by to up to €1m per vehicle’, said Karlsruhe Mayor Frank Mentrup at the unveiling ceremony.
It shows the value of standardisation and large orders.
Passenger Tunnel Linings At Waterloo Underground Station
This pictures show the cast-iron pedestrian tunnel linings at Waterloo tube station.
The Jubilee Line opened in 1999.
In the last few years, concrete has been able to be 3D-printed, so it can now be produced in different shapes.
All these wall and roof panels on the Elizabeth Line were made by 3D-printing of concrete.
Conclusion
Design has progressed in 25 years.
Concretene Cements Its Future With £8m Funding
The title of this post, is the same as that of this article in The Times.
This is a precis. which explains what Concretene have done.
Concretene combines graphene with concrete to form a “stronger, more sustainable and more cost-effective alternative” to the world’s most-used building material.
The eight million funding is mainly to be used for more tests.
Is Concrete The New Wonder Material?
I once lived in a concrete apartment and although it is now fifty years old, it still looks the same, as it did the day it was built.
Cromwell Tower
Cromwell Tower in The Barbican may have been built to a high specification, but we don’t hear cancer, cladding, damp, fire or mould problems about the City of London’s flagship housing estate.
In the last few years, concrete has been able to be 3D-printed, so it can now be produced in different shapes.
All these wall and roof panels on the Elizabeth Line were made by 3D-printing of concrete.
The technique also seems to be being used on High Speed Two.
These innovative uses of concrete have led to research into the manufacture and use of concrete.
These posts are must-reads.
- Carbon-Neutral Concrete Prototype Wins €100k Architecture Prize For UK Scientists
- UK Cleantech Consortium Awarded Funding For Energy Storage Technology Integrated With Floating Wind
- New HS2 Pilot Project Swaps Steel For Retired Wind Turbine Blades To Reinforce Concrete
- Earth Friendly Concrete
- HS2 Utilising UK-First Pioneering 3D Concrete Printing On Project
- Carbon Capture From Cement Manufacturing Nears Market Readiness
- Mineral Carbonation International Win COP26 Clean Energy Pitch Battle
The number of these posts show how much research is going into cutting the massive amount of carbon dioxide emitted by the concrete industry.
I also feel that some could work together.
Earth Friendly Concrete is a replacement for normal concrete, so perhaps it could be enhanced with graphene, to create an Earth Friendly Concretene.
National Grid Avoids Emissions At London Power Tunnels Substation With Green Grid Technology
The title of this post, is the same as that of this press release from National Grid.
These are the main bullet points.
- £1bn project to rewire London will see the replacement of ageing high-voltage electricity cables and expand network capacity to meet the increasing electricity demand
- A new substation at Bengeworth Road in Lambeth is at the heart of the project and will be built by Linxon using Hitachi Energy’s SF6 free gas insulated switchgear technology in a UK first
- The project forms part of National Grid’s ambition to have no SF6 in electrical assets by 2050
- National Grid is investing a total of £1.3bn every year in electricity network infrastructure needed to help the UK decarbonise and reach net zero emissions
I’ll now expand some of these points.
The London Power Tunnels
This is said about the London Power Tunnels.
National Grid’s London Power Tunnels (LPT) project is a seven-year, £1 billion project, to rewire South London via deep underground tunnels. This vital work to replace ageing high-voltage cables will expand capacity and help keep Londoners connected to secure and reliable electricity supplies.
Note.
- In total, there are 32.5km of 3m diameter tunnels.
- They stretch between Wimbledon and Crayford.
- As part of the project, a new tunnel access shaft, substation and headhouse is being built at Bengeworth Road, Lambeth to connect to our London Power Tunnels (LPT) route.
The London Power Tunnels have their own web site.
Sulphur Hexafluoride
This is said about Sulphur Hexafluoride.
Sulphur Hexafluoride (SF6 ) is used in the electricity industry in substations to prevent short circuits and to keep the network safe and reliable, but it has a high global warming potential. National Grid’s ambition is to reduce its SF6 emissions by 50% by 2030 and remove all SF6 gas from electrical assets by 2050.
Linxon is building Bengeworth Road substation for National Grid and to support the business in its transition to SF6 -free solutions, in a UK first, Hitachi Energy will deliver EconiQ™ 400-kilovolt (kV) gas-insulated switchgear (GIS) and gas-insulated lines (GIL) containing no SF6, to enable the transmission of energy over long distances. Installation is expected to begin in 2023, subject to prior approval of the substation by Lambeth Council.
In the Wikipedia entry for sulphur hexafluoride, this is said.
SF6 is 23,500 times more potent than CO2 as a greenhouse gas but exists in relatively minor concentrations in the atmosphere. Its concentration in Earth’s troposphere reached 10.63 parts per trillion (ppt) in 2021, rising at 0.39 ppt/year.[8] The increase over the prior 40 years was driven in large part by the expanding electric power sector, including fugitive emissions from banks of SF6 gas contained in its medium- and high-voltage switchgear. Uses in magnesium, aluminium, and electronics manufacturing also hastened atmospheric growth.
As I have a lot of experience of HF, my view is that we’re well shot of the SF6, but I’ll be 103, when National Grid eliminate it.
Striking “Bellingham” Bridge Set To Light Up HS2’s Gateway Into Birmingham
The title of this post, is the same as that of this news item from High Speed Two.
These three paragraphs describe the bridge in detail.
HS2 Ltd has revealed designs for the 150-metre section of viaduct as part of the approach to Birmingham’s new Curzon Street Station, including a 25-metre-high truss which will create a new icon on the city’s skyline.
A unique light installation, designed by British artist Liz West, will introduce a dynamic colour palette to the apertures of the steel truss, framing views of the city. Titled Out of the Blue, the proposed artwork will establish the bridge as a stunning feature of the city’s landscape both during the day and at night, when the artwork will come to life.
The Curzon 2 bridge, which has been nicknamed “The Bellingham Bridge” by the team in honour of England superstar and Stourbridge-born Jude Bellingham’s performances at the World Cup, is the tallest structure in the sequence of viaducts and structures that make up the Curzon Street Approaches. These Approaches take HS2 into Birmingham’s new city centre station. The bridge consists of a gently curved truss in weathering steel which carries HS2 over the Victorian brick rail viaduct below.
There are several more visualisations on the High Speed Two web site.
