Twenty First And Eighteenth Centuries Meet As HS2 Traverses Grand Union Canal

Is A Small Hydrogen Fuel Cell Car Possible?
By small car, I’m meaning something like a Ford Fiesta or a Vauxhall Astra.
Consider.
- The car will have a power unit of about 100 KW.
- With four passengers the car would probably weigh about 1500 Kg.
Does A 100 KW Fuel Cell Suitable For A Car Exist?
Intelligent Energy is a British company based in Loughborough.
This is their mission statement on their web site.
Focused on the development of lightweight, high efficiency, hydrogen fuel cell systems.
They also have this product page for a 110 KW fuel cell tailored for automotive use, that weighs 240 Kg.
I suspect if Ford asked for a fuel cell for a hydrogen Fiesta, that Intelligent Energy could provide one.
And I suspect other fuel cell companies could!
How Much Is The Kinetic Energy Of A Car Like This At 100 mph?
Using Omni’s Kinetic Energy Calculator, I get a figure of 422 Wh.
This figure means a battery of perhaps 2 KWh would handle regenerative braking and provide stationary power to get the car started.
Conclusion
From what I have written here, I believe that a hydrogen-powered small car is possible.
Coire Glas Exploratory Tunnel 70% Complete
The title of this post, is the same as that of this article in Ground Engineering.
This is the sub-heading.
A tunnel to investigate ground conditions at SSE Renewables’ Coire Glas project to build a pumped hydro scheme in the Scottish Highlands is 70% complete, as wider ground investigations come to an end.
These are the first three paragraphs.
Coire Glas on the shores of Loch Lochy in Great Glen is the first large scale pumped hydro storage scheme to be developed in the UK for more than 40 years.
It would take excess energy from the grid and use it to pump water 500m up a hill from Loch Lochy to a vast reservoir where it would be stored. This will be done through a tailrace tunnel, underground cavern power station, high pressure tunnel and low-pressure headrace tunnel.
SSE Renewables has started exploratory works on the scheme. This has involved building an up to 1km long and 4m wide tunnel to investigate the ground conditions in which the powerhouse will be built.
All the information gathered will be used in the detailed design of the 1,5GW/30 GWh pumped storage system, which is expected to be a £1.5 billion capital investment.
The Wikipedia entry for Coire Glas power station, says this about the current status and completion.
In December 2023, the exploratory tunnel had reached 720m in length.
A final investment decision will depend on UK government assurances about how the regulated electricity market would reward storage schemes. SSE hope to make that £1.5Bn decision in 2024, in which case the scheme could be completed in 2031.
I suspect that as this is one of the largest green energy projects in the UK, that there’ll be a lot of media coverage of the construction of this power station.
Rolls-Royce Supplies mtu Large-Scale Battery Storage To Secure The Latvian National Grid
The title of this post, is the same as that of this press release from Rolls-Royce.
These four bullet points, act as sub-headings.
- Latvia synchronizes its electricity grid with the European grid in 2025
- Large-scale battery storage system from Rolls-Royce ensures stability of the power grid in Latvia
- Transmission system operator AST orders 160MWh mtu EnergyPack
- Facility will be one of the largest battery storage systems in the EU
This is the first paragraph.
Rolls-Royce has received an order from the Latvian transmission system operator Augstsprieguma tikls (AST) to supply an mtu large-scale battery storage system to secure the Latvian power grid. In 2025, Latvia, together with the other Baltic states, will synchronize its energy supply system with the continental European power grid.
Note.
- This is a Rolls-Royce press release, not a Rolls-Royce mtu press release.
- Recently, Rolls-Royce mtu supplied the generators for Redditch power station, which I wrote about in Centrica Completes Work On 20MW Hydrogen-Ready Peaker In Redditch.
- In The Modern Way To Grow Tomatoes, I describe how a Rolls-Royce mtu Combined Heat and Power unit (CHP), is used in the growing of tomatoes.
Could it be that using the Rolls-Royce name prominently, makes sales easier?
Travelling Between London Stations
When I came home from Moorgate this morning, I took my usual 141 bus.
I sat next to a lady about forty, who from her bags looked like she’d just arrived by plane at Gatwick Airport.
After a couple of attempts at conversation, it became obvious, that we didn’t have a common language.
She then produced her phone and indicated that she needed Liverpool Street station.
The 141 bus doesn’t serve Liverpool Street station, but it does serve the Western entrance to Liverpool Street station on the Elizabeth Line.
It looks to me, that she had been told by a human being, an app or the Internet, that the easiest way from London Bridge bus station to Liverpool Street station was to take the 141 bus from in front of the station and walk across to Liverpool Street station from Moorgate.
But.
- The Western entrance to Liverpool Street station has no information to indicate, that it gives access to Liverpool Street station.
- The bus information system indicates Moorgate station.
- The bus information system does not announce, that for Liverpool Street station, you should alight at Moorgate station.
Perhaps, the bus information system should indicates Moorgate/Liverpool Street station.
Conclusion
How many other transfers between London stations are similarly confusing?
