Countdown To Swiss Record Attempt: Assembling A 1.91-kilometre Train
The title of this post, is the same as that of this article on RailTech.com.
The article explains all the things that they do to achieve this ultra-long train, but they do leave out the why!
I can only assume, that they want to test the train software in the most extreme of circumstances and they feel that this is the best they can do!
Knoydart Renewables – The Power of Knoydart
The BBC has been showing a film all day about the Knoydart area of the Scottish Highlands and their community-owned hydroelectric power system.
The title of this post, is the same as that of this page on the Knoydart Foundation web site.
This paragraph introduces the system.
Knoydart is not connected to the National Grid and generates all of its own electricity. Other than some small run-of-burn micro-schemes in outlying hamlets, by far and away the the main producer and distributer of electricity on Knoydart is Knoydart Renewables Ltd. that supplies electricity around Inverie Bay.
Note.
- The system is based on a 280 kW turbine and generator.
- The turbine is fed over a kilometer by steel and plastic pipe from a man-made loch with an estimated storage capacity of at least 74 MWh.
- There is a back-up diesel generator.
- 120 residents in 90 properties are supplied with electricity.
It sounds like a very professional system for a community with a convenient hill and water supply.
The system is being expanded and connected to the grid.
The whole page is a must read for anyone, who wants to put in a small hydroelectric power station for their house, castle or community.
X1 Wind – Disrupting Offshore Wind
The X1 Wind web site talks about disrupting offshore wind.
On the home page, they have this statement.
Oceans Contain The Largest Energy Resource On The Planet, Which Remains Untapped
They back it up with this reference.
We estimate the total global technical potential of offshore wind as 71 TW (World Bank, 2021), of which 70% is in deep waters, suited to floating wind.
The home page also has a continuous video of their floating wind turbine, which they call a PivotBuoy.
- The wind turbine is mounted on a triangular float.
- The turbine nacelle is supported on a tripod.
- The turbine faces downwind.
- The float is held in place by a single point mooring.
The float and the turbine automatically align with the wind.
This article on offshoreWIND.biz is entitled X1 Wind Installs Downwind Floating Prototype and gives more details of the turbine.
It’s certainly different.
Centrica Re-Opens Rough Storage Facility
The title of this post, is the same as that of this press release from Centrica.
It has this sub-heading.
Rough Operational For Winter And Increases UK’s Storage Capacity By 50%.
On the face of it, this sounds like good news and these two paragraphs give more details.
Centrica has announced the reopening of the Rough gas storage facility, having completed significant engineering upgrades over the summer and commissioning over early autumn.
The initial investment programme means the company has made its first injection of gas into the site in over 5 years and is in a position to store up to 30 billion cubic feet (bcf) of gas for UK homes and businesses over winter 2022/23, boosting the UK’s energy resilience.
Note.
- The Rough gas storage facility has been able to hold up to 100 billion cubic feet of gas in the past.
- Rough is a complex field with two platforms and thirty wells transferring gas to and from the facility.
- Additionally, there is an onshore gas-processing terminal at the Easington Gas Terminal, where it connects to the UK gas network.
It appears to be a comprehensive gas storage facility, that should get us through the 2022/3 winter.
These two paragraphs from the press release, which are the thoughts of the Centrica Chief Executive are significant.
Centrica Group Chief Executive, Chris O’Shea, said “I’m delighted that we have managed to return Rough to storage operations for this winter following a substantial investment in engineering modifications. Our long-term aim remains to turn the Rough field into the world’s biggest methane and hydrogen storage facility, bolstering the UK’s energy security, delivering a net zero electricity system by 2035, decarbonising the UK’s industrial clusters, such as the Humber region by 2040, and helping the UK economy by returning to being a net exporter of energy.
“In the short term we think Rough can help our energy system by storing natural gas when there is a surplus and producing this gas when the country needs it during cold snaps and peak demand. Rough is not a silver bullet for energy security, but it is a key part of a range of steps which can be taken to help the UK this winter.”
Note.
- Effectively, in the short term, Rough is a store for gas to help us through the winter.
- In the long-term, Rough will be turned into the world’s largest gas storage facility.
- It will be able to store both methane (natural gas) and hydrogen.
Having worked with project managers on complex oil and gas platforms and chemical plants, I wouldn’t be surprised to find, that when the design of this facility is released, it will be something special.
Centrica certainly seem to have upgraded Rough to be able to play a significant short term role this winter and they also seem to have developed a plan to give it a significant long-term role in the storage of hydrogen.
Aldbrough Gas Storage
A few miles up the coast is SSE’s and Equinor’s Aldbrough Gas Storage, which is being developed in salt caverns to hold natural gas and hydrogen.
Blending Of Hydrogen And Natural Gas
I believe that we’ll see a lot of blending of hydrogen and natural gas.
- Up to 20 % of hydrogen can be blended, without the need to change appliances, boilers and processes.
- This cuts carbon dioxide emissions.
I wrote about this in a post called HyDeploy.
It might be convenient to store hydrogen in Aldbrough and natural gas in Rough, so that customers could have the blend of gas they needed.
With two large gas stores for hydrogen under development, the HumberZero cluster is on its way.
