Decarbonising The Mid-Cornwall Metro
Although the Mid-Cornwall Metro will probably run initially using what diesel multiple units, after a year or so, the route will be converted to zero-carbon operation.
Newquay To Falmouth Docks
This map shows the Mid-Cornwall Metro.
These are current timings.
- By train can take almost three hours with changes at Par and Truro.
- By car should take 45 minutes to drive the 24.4 miles according to Google.
Note.
- The train timings are for a typical British Rail-era Diesel Multiple Unit on the branches and something smarter between Truro and Par.
- A Day Return ticket would cost £8.90 without a Railcard.
- If there was a through train, that meant you didn’t have to change trains, I estimate that the time could be as low as one hour and 35 minutes.
I feel that most travellers, who had access to a car, would use that to travel between Newquay and Truro.
Newquay To Falmouth Docks By Electric Train
I have ridden in three battery-electric trains.
- Class 379 train – Manningtree and Harwich in passenger service.
- Class 230 train – Vivarail demonstration
- Class 777 train- Liverpool Central and Headbolt Lane in passenger service.
Note.
- All were mouse-quiet.
- There was no detectable difference, when running on battery power in the trains.
It is my view that battery-electric trains are no second-class solution.
Consider.
- Newquay and Par is 20.8 miles.
- Falmouth Docks and Par is 30.8 miles.
- Newquay and Falmouth Docks is 51.6 miles.
- The maximum speed between Par and Newquay is around 30 mph
- The maximum speed between Par and Falmouth Docks is around 50-70 mph
- There are twelve intermediate stations.
- There is a reverse at Par station.
- Charging would be easy to install at Falmouth Docks, Newquay and Par.
- In Par Station – 10th February 2024, I suggested that Par station could be fully-electrified, so that expresses could have a Splash-and-Dash on their way to London and Penzance. If all platforms at Par were electrified the Mid-Cornwall Metro trains could charge from the electrification, as they reversed.
There are two main ways that the Mid-Cornwall Metro might operate.
- There would be chargers at Newquay and Falmouth Docks and trains would shuttle the 51.6 miles between the two stations.
- There would only be charging at Par and trains would after charging at Par go alternatively to Newquay and Falmouth Docks.
The first might need smaller batteries and the second would only need one charger.
Newquay To Falmouth Docks By Hydrogen-Powered Train
There is only one hydrogen-powered train in service and that is the Alstom Coradia iLint, which is running in Germany.
I feel it is very much an interim design, as Alstom has taken a diesel-mechanical Lint train and swapped the diesel for a hydrogen-powered electricity generator and an electric motor.
But Alstom are putting together a hydrogen-powered train based on an Aventra.
Note.
- The train is three cars.
- I would envisage performance of the hydrogen train would be very similar to that of a similar battery-electric train.
- I wouldn’t be surprised that refuelling of the train would not be a problem, as with all the china clay working nearby, there may well be developments to use hydrogen in the industry to decarbonise the mining.
The Mid-Cornwall Metro and Alstom’s Hydrogen Aventra could be ideal for each other.
Conclusion
I believe, that although the Mid-Cornwall Metro will start operation with diesel multiple units, it will be running in a zero-carbon mode within a few years.
ICE Report Shows Majority Open To Net Zero Changes
The title of this post, is the same as that of this article on The Engineer.
This is the sub-heading.
A new report has found that a majority of the UK public is amenable to the behavioural changes needed to hit the country’s net zero targets.
These two paragraphs summarise the findings of the report.
Published by the Institution of Civil Engineers (ICE) and the All-Party Parliamentary Group on Infrastructure (APPGI), the report was based on a survey of 1,000 respondents. It found that 57 per cent were open to change, with 23 per cent described as net zero enthusiasts who were likely to have already altered their behaviours, and 34 per cent wanting change, but feeling they needed further empowerment to achieve it.
However, there is far from universal agreement when it comes to behavioural change around climate action. The report found that 30 per cent of people were ‘reluctant followers’, largely acknowledging that the UK must act on emissions, but not feeling personal responsibility for that action. This segment will likely only change their behaviours if forced to do so or seeing a majority of others doing it first. Finally, 13 per cent of those surveyed were classed as ‘net zero resistors’, people who don’t believe action is necessary and have no intention of doing so.
Summing the figures up gives us.
- Net-Zero Enthusiasts – 23 %
- Wanting Change – 34 %
- Reluctant Followers – 30 %
- Net-Zero Resistors – 13 %
All politicians should be forced to read the full report.
What Would I Need To Do To Achieve a Personal Net-Zero?
My circumstances probably cover a lot of people.
- I am a widow living alone.
- My house is well-insulated with solar-panels on the roof, but heated by gas.
- I don’t have or need a car.
- I do nearly all my shopping by public transport and carry it home.
- When I go away in the UK I use trains.
- If I go to Europe, I either go or come back by train.
- I am coeliac, which means I need to eat some meat to stay healthy.
My largest carbon-emitted is probably my house, but it would be unsuitable for most current solutions.
I would put myself in the Wanting Change group, but I could move to a Net-Zero Enthusiast, if the right technology came along.
- I have seen one bolt-in electric replacement for by boiler and when the right one arrives, I’ll probably fit one.
- An affordable battery to work to with my solar panels and also allow me to use Off Peak electricity would be nice.
- As I’m coeliac, I tend to buy in the same food each week from Marks and Spencer to eat in. I might be able to cut my carbon footprint by getting Ocado to deliver. Especially, as some deliveries seem to be bike.
- If TfL decarbonised the bus, that I use most days to and from Moorgate would that lower my carbon footprint?
I suspect the largest amount of carbon outside of my house’s heating, that I’ll emit, will be tomorrow, when I take a train to Newquay.
How Do We Convert The 13 % Net-Zero Resistors?
The recent protests by French and Belgian farmers indicate, that these farmers are probably in this group. And there are other forthright groups!
The only way, that they’ll be converted, is if technology allows them to earn the same amount of money and have the same outgoings, as they do now!
University Of Leeds Drills Test Boreholes For Geothermal Project To Heat Campus
The title of this post, is the same as that of this article on Ground Engineering.
This is the sub-heading.
A team of researchers at the University of Leeds has started to test the potential to use geothermal energy to heat buildings on campus in a bid to tackle its carbon emissions.
These three paragraphs outline the project.
The project involves drilling eight test boreholes into the ground at several locations on the campus at depths of between 150m to 250m. Work started last Monday (29 January) and will continue until May 2024.
Some of the holes will be water wells at around 50cm in diameter that will look for underground aquifers at the right temperature to use for geothermal heat. Other holes will be monitoring wells at around 15cm in diameter which the team will use to check what impact extracting heat from the ground has on the surrounding areas.
The geothermal project brings together the team responsible for the maintenance and development of the University estate and an academic team which includes professor of geo-energy engineering Fleur Loveridge, research fellow in geosolutions David Barns and lecturer in applied geophysics and structural geology Emma Bramham.
The Wikipedia entry for Geothermal Energy In The United Kingdom, is a very informing and ultimately surprising read.
This is the introductory paragraph.
The potential for exploiting geothermal energy in the United Kingdom on a commercial basis was initially examined by the Department of Energy in the wake of the 1973 oil crisis. Several regions of the country were identified, but interest in developing them was lost as petroleum prices fell. Although the UK is not actively volcanic, a large heat resource is potentially available via shallow geothermal ground source heat pumps, shallow aquifers and deep saline aquifers in the mesozoic basins of the UK. Geothermal energy is plentiful beneath the UK, although it is not readily accessible currently except in specific locations.
With more projects like that at the University of Leeds and the development of better technology, I am confident that over the next few years, we will extract more heat from beneath our feet.
A New Future Beckons For Scotland’s Historic Canals
The title of this post is the same as that as this article on The Herald.
This is the sub-heading.
Scotland’s canals, created for the industrial revolution but in recent times focused more on leisure than industry, are finding a new purpose as a different revolution, this time a green one, gets underway
The article was found by my Google Alert for the Coire Glas project, which is one of the UK’s largest green projects.
The article describes how Scotland’s canals are helping a green revolution and is well worth a read.
Funding Announced For First-In-Class Low-Carbon Installation Vessel For Floating Offshore Wind
The title of this post, is the same as that of this news item from Morek Engineering.
These two paragraphs outline the project.
The UK Government has awarded funding to a consortium led by Morek Engineering to design a new class of low-carbon installation vessel for the floating offshore wind market.
The consortium has won the funding through the UK Government’s Clean Maritime Demonstration Competition based on their proven track record in innovative vessel design and delivery of complex offshore operations. The consortium includes Morek Engineering, Solis Marine Engineering, Tope Ocean, First Marine Solutions and Celtic Sea Power.
Note.
- The design of the ship certainly seems to tick all the boxes.
- This is Morek’s web site.
Because of my experience of writing project management systems, I often wonder, whether some of my discarded ideas of the 1980s could be used in the deployment of floating offshore wind.
Poo power To Heat Homes In West London As Thames Water Continues To Reduce Its Carbon Footprint
The title of this post, is the same as that of this press release from Thames Water.
These are the three bullet points.
- Thames Water unveils its second successful gas-to-grid project.
- Around 4000 homes in West London will be heated using converted sewage sludge from Mogden sewage treatment works starting early this year.
- This initiative is part of Thames Water’s commitment to reduce its carbon emissions across its operations thereby reducing its contribution to the causes of climate change.
These three paragraphs outline the project.
Thames Water has announced sewage sludge will be used to heat homes in West London early this year, after successfully delivering its second gas-to-grid (G2G) project, at its Mogden Sewage Treatment Works (STW).
The success of the gas-to-grid model established at Deephams STW in North London in 2021, where biogas is converted into biomethane to heat homes in Enfield, served as the blueprint for the project at Mogden.
Currently serving over 2 million customers, Mogden is the third largest STW in the UK, and has the potential to reach and supply gas to 4000 homes in West London. This comes as part of the company’s commitment on energy transition, by transforming the way it creates and uses power to reach net zero carbon emissions.
The press release then gives a paragraph of explanation as to how the system works.
A byproduct of the sewage treatment process is sewage sludge, which is then digested to produce BioGas. Mogden STW then generates electricity with this BioGas via Combined Heat and Power (CHP) engines. The Gas-to-Grid plant, which will be managed by gas supplier SGN, intends to take a proportion of this BioGas and to ‘uprate’ it to export quality which is achieved by filtering, scrubbing and then compressing gas so it can be used as fuel for cooking and heating.
This Thames Water graphic illustrates the process.
This press release is not Thames Water’s image from many of its customers.

- Five-car – 176
- Seven-car – 4
- Nine-car – 63
That is a total of 1254 trains that need to be decarbonised by either replacement or modification.
- Some trains are effectively double-counted, as both the current trains and their replacements are included.
- Some trains are planned to be replaced by electric trains.
- Some trains will be passed on.
But there are still a lot of trains to be decarbonised.
I will now look at each group in detail.
BR Second Generation Trains
- Class 150 – 129 x two-car and 6 x three-car.
- Class 153 – 36 x one-car.
- Class 155 – 7 x two-car.
- Class 156 – 109 x two-car.
- Class 158 – 155 x two-car and 15 x three-car.
- Class 159 – 29 x three-car.
- Class 165 – 59 x two-car and 16 x three-car.
- Class 166 – 21 x three-car.
Note.
- The trains have mostly Cummins engines, with some Perkins and a spattering of Rolls-Royce.
- Class 150,153, 155 and 156 trains are 75 mph trains and most of the others are capable of 90 mph.
- Condition of the interiors is variable, with some being excellent and others being terrible.
- There are 36 x one-car, 459 x two-car and 59 x three-car.
- There appears to be no plan to decarbonise these trains.
- Some will be replaced by new CAF diesel trains or new electric trains.
The best use of some of the better trains in this group would be to fill-in until zero-carbon trains are available.
Turbostar Trains
These trains are all Turbostars or their predecessor.
- Class 168 – 9 x two-car, 9 x three-car and 13 x four-car.
- Class 170 – 34 x two-car and 71 x three-car.
- Class 171 – 17 x three-car.
- Class 172 – 24 x two-car and 15 x three-car.
Note.
- The trains all have Rolls-Royce mtu engines.
- They are capable of 100 mph.
- Condition of the interiors is generally good.
- There are 67 x two-car, 112 x three-car and 13 x four-car.
- Rolls-Royce mtu engines may be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
- 168329 has been converted into a diesel-hybrid, by Rolls-Royce mtu.
I feel that one way or another, the trains in this group should be capable of converting to net-zero operation.
Alstom Coradia, Bombardier Voyager and Siemens Desiro Trains
I am putting these trains together, as they are all 100-125 mph long-distance trains, that are not that old.
- Class 175 – 9 x two-car and 15 x three-car.
- Class 180 – 1 x four-car and 12 x five-car.
- Class 185 – 51 x three-car.
- Class 220 – 34 x four-car
- Class 221 – 24 x four-car and 18 x five-cars
- Class 222 – 23 x five-car and 4 x seven-car.
Note.
- The trains all have Cummins engines.
- They are capable of 100 mph or 125 mph.
- Condition of the interiors is generally good.
- There are 9 x two-car, 66 x three-car, 59 x four-car, 53 five-car and 4 x seven-car.
- Cummins engines may be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
- In Grand Central DMU To Be Used For Dual-Fuel Trial, I described innovative fuel trails in a Class 180 train.
- I suspect Cummins will be taking an interest.
In Cummins And Leclanché S.A. To Collaborate On Lower-Emissions Solutions For Use In Marine And Rail Applications, I asked this question.
How many of these trains could be converted to hybrid operation, if Cummins and Leclanché were to create their version of the mtu Hybrid PowerPack?
I feel that one way or another, the trains in this group should be capable of converting to net-zero operation.
CAF Civity Trains
These three trains have all been recently introduced
- Class 195 – 25 x two-car and 33 x three-car.
- Class 196 – 12 x two-car and 14 x four-car.
- Class 197 – 51 x two-car and 26 x three-car.
Note.
- The trains all have Rolls-Royce mtu engines.
- They are capable of 100 mph.
- Condition of the interiors is probably as-new!
- There are 88 x two-car, 59 x three-car and 14 x four-car.
- All these trains were ordered between 2016 and 2018.
- Rolls-Royce mtu engines may be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
I don’t believe that as these trains were only ordered a few years ago, that the trains were bought with the knowledge of a route which would convert these trains to net-zero operation.
I suspect the most likely route to net-zero operation, would involve the following.
- Replacing the Rolls-Royce mtu engines with mtu Hybrid PowerPacks.
- Running the trains on sustainable fuel.
The work needed would probably be the same for all trains.
Stadler FLIRT Bi-Mode Trains
- Class 231 – 11 x four-car.
- Class 755 – 14 x three-car and 24 x four-car.
- Class 756 – 7 x three-car and 17 x four-car.
Note.
- The trains all have Rolls-Royce mtu engines.
- They are capable of between 75 and 100 mph.
- Condition of the interiors is probably as-new!
- There are 21 x three-car and 52 x four-car.
- All these trains were ordered between 2016 and 2018.
- As with other recently ordered trains, I am fairly sure that the Deutz engines will be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
Stadler have designed these trains, so that diesel engines can be replaced by battery packs.
I suspect the most likely route to net-zero operation, would involve the following.
- Replacing all or some the Deutz engines with battery packs.
- Running the trains on sustainable fuel.
The work needed would probably be the same for all trains.
Hitachi AT-300 Trains
Only the bi-mode trains are lists.
- Class 800 – 31 x five-car and 49 x nine-car.
- Class 802 – 46 x five-car and 14 x nine-car.
- Class 805 – 13 x five-car.
- Class 810 – 33 x five-car.
Note.
- The trains all have Rolls-Royce mtu engines.
- They are capable of 125 mph.
- Condition of the interiors is probably as-new!
- There are 123 x three-car and 63 x nine-car.
- Most were built after 2016.
- Rolls-Royce mtu engines may be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
- Hitachi are developing battery packs for these trains.
I suspect the most likely route to net-zero operation, would involve the following.
- Replacing all or some the Rolls-Royce mtu engines with battery packs.
- Running the trains on sustainable fuel.
The work needed would probably be the same or similar for all trains.
Schneider Electric: Vertical Farming – The Next Yield In Data Centre Sustainability
The title of this post, is the same as that of this article on Intelligent Data Centres.
This is the sub-heading.
David Abrahams, Key Client Manager, Cloud and Service Partners at Schneider Electric UK and Ireland, discusses vertical farming and the next yield in data centre sustainability. He outlines new data centre sustainability strategies, vertical farming solutions and how data centres can apply already existent models which will allow plants and crops to thrive in unique Growth Towers.
These are the first two paragraphs.
As data centres begin to reach their physical sustainability limits without redefining the laws of physics, vertical farming could provide a new solution to the decarbonisation challenge, creating a symbiotic environment for both data and nature to benefit one another.
Coined by some as the fourth revolution in agriculture, vertical farms today provide closed conditions which deliver major sustainability benefits including limited or zero use of pesticides, while ensuring the farm is safe from extreme weather-related events such as high temperatures, humidity, floods and fires.
The last section is called Making The Concept A Reality, where these are the first three paragraphs.
Equinix has already taken the leap and has become the first global operator to develop a fully functioning vertical farm at its PA10 Paris data centre, creating a 4600 sq.ft greenhouse which is surrounded by 61,000 sq.ft of garden space.
The vertical farm is kept at an ideal growing temperature, using heat exchangers linked to the data centre’s chilled water-cooling system with sensors that monitor internal and external temperatures and humidity levels. With such available technology, farmers will be able to make real-time changes to their growing conditions to achieve higher yields at lower energy. This could be a game changer considering the greater strain on the global food supply chain and the general cost of energy.
With increased demands for efficiency and sustainability, both data centre and agricultural sectors are under the greatest scrutiny. The idea of data centre and farming worlds collaborating to create a circular economy to help futureproof both industries is not only exciting but unveils a world of new decarbonisation opportunities.
It strikes me that combining a data centre and a vertical farm could be a marriage made in eco-heaven.
I suggest you read all the original article.
Google Starts Building £790m Site In Hertfordshire
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
Google has invested $1bn (£790m) to build its first UK data centre
These are the first four paragraphs.
The tech giant said construction had started at a 33-acre site in Waltham Cross, Hertfordshire, and hoped it would be completed by 2025.
Google stressed it was too early to say how many jobs would be created but it would need engineers, project managers, data centre technicians, electricians, catering and security personnel.
The prime minister said it showed the UK had “huge potential for growth”.
The project marked the latest investment by a major US tech firm in Britain, after Microsoft announced it would invest £2.5bn to expand data centres for artificial intelligence (AI) across the UK.
Note.
- By “completed by 2025” do they mean completed before 2025 or completed by the end of 2025. Judging by the time they took to build their London HQ, its the latter.
- Rishi is right about the UK having a huge potential for growth! Especially, if the nihilists of the United States vote in the Big Orange!
- Judging by the total spend of £2.5 billion on data centres and the £790 million for this one, this looks to be the first of three.
But where is this data centre going to be built?
This article on EssexLive is entitled Google To Move Into Waltham Cross With £788m Data Centre To Support ‘AI Innovation’, where this is said.
The new data centre will go on land at Maxwell’s Farm, next to the A10 Great Cambridge Road and around one mile from the M25 junction 25. Debbie Weinstein, Google vice president and managing director in the UK and Ireland, set out the decision in a blog post on Thursday, January 18 – the fourth day of the World Economic Forum’s Davos 2024 in Switzerland.
This is a Goggle Map of that area, when I searched for Maxwell’s Farm.
Note.
- The red arrow indicates the result of my search, which Google interpreted as A.J. Maxwell.
- The dual-carriageway road running down the East side of the map is the A10 between London and Cambridge.
- The A10 road joins the M25 at Junction 25.
- The arrow to the South-West of the roundabout indicates the new studios; Sunset Waltham Cross, which is being built.
- At the other side of the studio site, there is a label saying New River and this important piece of London’s water infrastructure can be traced to the top of the map.
- The other dual-carriageway road is the B198 or Lieutenant Ellis Way.
- A quick calculation shows that 33 acres is roughly a 365 metre square.
I would suspect that the data centre will lie somewhere between the A10, the B198 and the New River.
This Google Map shows the South-East corner of the site.
Note.
- There appears to be a lane running East-West, that crosses over both the A10 and the New River.
- Theobalds Lane appears to have some housing and possibly a farm.
- The smaller field by the roundabout appears to have some animals using it as grazing.
- The field between the East-West lane and Theobalds Lane appears to have a good crop of cereal.
The East-West lane would appear to be a possible Southern border of the site.
This Google Map shows where the East-West lane goes.
Note.
- The lane leads to Queen Mary’s High School.
- The school also has access from Lieutenant Ellis Way.
- The New River appears to form, the Eastern boundary of the school site.
- There are sports pitches between the New River and the school.
The New River looks to be the Western boundary of the Google site.
This Google Map shows around the red arrow from the Google search that led me to this area.
Note.
- A.J. Maxwell is identified by the red arrow in the Theobalds Enterprise Centre.
- The New River can be seen at the West of the map.
- A hedge runs roughly East-West to the North of the Enterprise Centre.
- North of the hedge are a number of football pitches, which appear to belong to the Affinity Academy at Goffs Churchgate.
The hedge could be the Northern boundary of the Google site.
This Google Map shows the area between the South of the Enterprise Centre and the East-West lane I picked out earlier.
A crude measurement indicates it could be around 33 acres or slightly more.
This picture is used in nearly all the news reports about the Data Centre.
Note.
- Could that be the gentle curve of the New River on the left?
- With the high fence, the New River forms an almost-mediaeval defence against trespassers.
- There looks to be a dual-carriageway road running down the other side of the site, which would be the A10.
- Between the A10 and the site, there appears to be loots of dark areas, which I take to be car parks.
- Are the car-parking spaces in the front of the picture marked for those, who are disabled? There certainly appear to be chargers on some spaces.
I have a few thoughts.
The Relative Locations Of Google’s Data Centre And Sunset Studios?
This Google Map shows the two sites to the West of the A10.
Note.
- St. Mary’s High School is in the North-West corner of the map.
- Cheshunt Football Club is in the North-East corner of the map.
- The dual-carriageway A10 runs North-South on the map.
- I believe that Google’s Waltham Cross Data Centre will be located in the field to the West of the A10, at the top of the map.
- The A10 connects to the M25 at Junction 25, which is in the centre at the bottom of the map.
- In The Location Of Sunset Studios In Broxbourne, Sunset Studios are placed to the North West of the Junction 25 roundabout.
- Just as the A10 forms the Eastern boundary of both sites, the New River forms the Western boundary.
The two sites are close together between the A10 and the New River, separated by the dual-carriageway Lieutenant Ellis Way.
Will Google’s Data Centre Be Storing Data For Sunset Studios?
I’ve never worked in the production of films, but these days with digital electronic cameras, CGI, motion capture and other techniques, producing a film must need huge amounts of data storage.
- So have Sunset Studios outsourced their data storage needs to Google?
- Perhaps too, Sunset Studios found the local authority welcoming and this attitude was recommended to Google.
- Both sites will need local services like electricity, gas, sewage and water.
I suspect that there would be cost savings in construction and operation, if the two sites shared the utilities.
Providing Electricity And Heat For Both Sites
Consider.
- I estimate from information given in the Wikipedia entry for Google Data Centres, that a data centre needs between 10 and 12 MW.
- There is no obvious power source like offshore wind or a nuclear power station nearby.
- There is the 715 MW Rye House gas-fired power station, which is a few miles away.
- In Google Buys Scottish Offshore Wind Power, I talked about how Google had signed a Corporate Power Purchase Agreement to buy 100 MW from the Moray West offshore wind farm.
Google and Sunset Studios would also want an electrical and heat supply that is at least 100 % reliable.
Liverpool University had the same problem on their hundred acre campus in the centre of Liverpool.
- The University decided to build their own 4 MW Combined Heat and Power Unit (CHP), which is described in this data sheet.
- It is fired by natural gas.
- On their web site, Liverpool University state that their CHP can be adapted to different fuel blends. I take this includes zero-carbon fuels like hydrogen and carbon-neutral fuels like biomethane.
But given their location in Waltham Cross close to the Lea Valley, CHP units may have a use for their carbon dioxide.
This Google Map shows between Junction 15 of the M25 and Tomworld.
Note.
- Junction 25 of the M25, where it joins the A10 is in the South-West corner of the map.
- The sites of Google’s Data Centre and Sunset Studios can be picked out with reference to the previous map.
- Tomworld is in the North-East corner of the map.
- So why should Tomworld need a lot of carbon-dioxide?
This Google Map shows Tomworld.
Note.
- This web page indicates what Tomworld do.
- They have 44 acres of glass growing tomatoes, about five miles to the North-East of Google’s Data Centre.
- The map has lots of other greenhouses.
I know of a guy, who has a large greenhouse, that grows tomatoes for the supermarkets.
- He heats the greenhouse with a gas-fired Combined Heat and Power Unit (CHP).
- The electricity produced runs his business.
- Any surplus electricity is fed into the grid.
- The carbon dioxide is fed to the plants in the greenhouse, which helps them grow quality tomatoes.
I just wonder, if carbon dioxide from CHP units at Google’s Data Centre and Sunset Studios could be used by the multitude of greenhouses in the Lea Valley.
Could A Carbon Dioxide Pipeline Be Built Along The M25?
This Google Map shows the Northern section of the M25, South of Waltham Cross.
Note.
- The M25 running East-West across the bottom of the map.
- Junction 25 of the M25 in the South-West corner of the map.
- The A10 running North-South at the West of the map.
- Google’s data centre and Sunset Studio are to the West of the A10.
- The River Lee, which has numerous water courses is at the East of the map.
I wonder, if a carbon dioxide pipeline could be built along the M25 to connect the producers to those who could use it?
- It would not be a dangerous pipeline as carbon dioxide is a fire extinguisher.
- It wouldn’t be a huge pipe.
I think it would be possible.
Google’s Commitment To Being Zero-Carbon
This blog post on the Google web site is entitled Our $1 Billion Investment In A New UK Data Centre, has a section, which has a sub-title of 24/7 Carbon-Free Energy By 2030, where this is a paragraph.
Additionally, we’re also exploring new and innovative ways to use the heat generated by data centres, and this new facility will also have provisions for off-site heat recovery. Off-site heat recovery presents an opportunity for energy conservation that benefits the local community, as it allows us to capture the heat generated by the data centre so that it can be used by nearby homes and businesses. The data centre is also set to deploy an air-based cooling system.
If they are using off-site heat recovery, it would be logical to use waste carbon dioxide from CHPs to provide carbon dioxide for the local horticultural businesses.
Will Google Be Building A Vertical Farm Nearby?
In Schneider Electric: Vertical Farming – The Next Yield In Data Centre Sustainability, I noted that some data centres are paired with vertical farms to increase their sustainability.
Could Google be doing that in Waltham Cross?
- They will have a lot of waste heat.
- They will have a fair bit of carbon dioxide, which could be used to help plants grow.
- The local workforce probably contains a lot of experience of market gardening.
I like the idea of pairing a data centre and a vertical farm.
Public Transport Access
Consider.
- Increasingly, the cost of electric vehicles, medical problems and the UK economic situation are causing people to adopt a car-free lifestyle.
- After my stroke, my eyesight deteriorated such, that I am no longer allowed to drive.
- Others may live in one-car families and it may not be their’s to use every day.
- Or your car may just break down on the way to work.
For these and probably lots of other reasons, any large site employing a lot of employees, must have a valid way of getting there by public transport.
The nearest rail station to Google’s Data Centre and Sunset Studios is Theobalds Grove station.
This Google Map shows the roads between the sites and the station.
Note.
- The Sunset Waltham Cross label in the South West corner.
- Google’s Data Centre will be just off the map to the West of the A10.
- Theobalds Grove station is marked by the TfL roundel in the North-East corner of the map.
- There would appear to be no bus stops on Winston Churchill Way or the A10.
I walked South from the station to Winston Churchill Way, where I took these pictures.
Note.
- At that point, I gave up because of the cold and pollution.
- It was also a Saturday morning about midday.
The route I took is certainly not an alternative route to get to Google’s Data Centre or Sunset Studios.
A Possible Station At Park Plaza North
This article on the BBC is entitled Broxbourne: Two New Stations Planned.
This is the sub-heading.
Two new train stations could be built in Hertfordshire if plans to tighten planning policies are adopted.
This is the first paragraph.
Broxbourne Borough Council said stops at Park Plaza North – between Turkey Street and Theobalds Grove London Overground stations – and Turnford on the London to Bishop’s Stortford route would be subject to a consultation.
Later the BBC say that Park Plaza North station will be South of the A121 Winston Churchill Way near Waltham Cross
This Google Map shows the area South-East of the roundabout, where Winston Churchill Way meets the A10.
Note.
- The green patch of land to the South-East of the roundabout where Winston Churchill Way meets the A10 appears to be ripe for development.
- Looking at the green patch with a higher resolution, the land is little more than high class scrub beloved of newts.
- The London Overground line to Cheshunt runs down the East side of the site.
- To the North, the London Overground crosses Winston Churchill Way to get to Theobalds Grove station.
- To the South, the London Overground crosses the M25 to get to Turkey Street station.
- There is a lane running East-West along the South edge of the site, which crosses the railway in a level crossing.
This picture clipped from Google StreetView shows the level crossing.
This is certainly one, that drivers dread.
This GoogleMap shows the level crossing and a stretch of the London Overground.
Note.
- The level crossing is in the South-East corner of the map.
- There isn’t much space to put a London-bound platform on the East side of the tracks, South of the Park Road circle.
- There is plenty of space to put a Cheshunt-bound platform on the West side of the tracks.
- North of the Park Road circle, there would appear to be space for two platforms.
It will need a lot of ingenuity to provide a safe and efficient solution to the problems of the level crossing and fitting a station in this limited space.
The first thing I’d do, would be to dig an underpass for pedestrians and cyclists to connect the two halves of Park Lane.
