Cars In Central London Surged 60% After Khan Stopped Evening Congestion Charge

The title of this post, is the same as that of this article on the Standard.

These are the first two paragraphs.

Transport for London’s own data shows the dramatic impact of the Mayor’s decision to shorten the £15-a-day C-charge’s operating hours, ending it at 6pm rather than 10pm.

Last February, an average of 12,968 vehicles entered the zone between 6pm-10pm. But by October this had increased to 20,654 — a rise of 59 per cent.

To a Control Engineer like me, it is obvious that if you reduce the cost of the London Congestion Charge in the evenings between 18:00 and 22:00, you’re going to get more traffic.

Was that what was intended?

Or was the Mayor given bad advice?

I would have thought, the best course of action would have been to keep the charges as they were and use some the money to improve public transport in the central area.

First Offtake Deal Signed For 500MW/4,000MWh Advanced Compressed Air Energy Storage Project In California

The title of this post, is the same as that of this article on Energy Storage News.

These three paragraphs explain the deal.

Advanced compressed air energy storage (A-CAES) company Hydrostor has signed a power purchase agreement (PPA) for one of its flagship large-scale projects in California.

Central Coast Community Energy, one of California’s several dozen Community Choice Aggregator (CCA) non-profit energy suppliers, has signed a 200MW/1,600MWh energy storage PPA with a 25-year term with Toronto-headquartered Hydrostor for its Willow Rock Energy Storage Center.

That’s just under half of the output and capacity of the planned 8-hour, long-duration energy storage (LDES) facility, which is designed to be 500MW/4,000MWh. This is its first offtake deal, but the company is in discussion for others to take the rest of the plant’s available resource.

The article says that Hydrostor aim to have the plant online by 2028.

This segment describes their current projects.

It is currently working on large-scale projects with around 9GWh storage capacity in total across two sites in California as well as another in Australia.

Together with Willow Rock in Kern County, Hydrostor is developing the 400MW/3,200MWh Pechos Energy Storage Center in San Luis Obispo County, California, and the 200MW/1,500MWh Silver City Energy Storage Center in Broken Hill, New South Wales, Australia.

On its UK Projects page, Highview talks about a 200MW/2.5GWh facility in Yorkshire, which puts the two companies in similar markets, with Hydrostor appearing to have slightly larger systems under development.

Conclusion

It will be interesting to see how this technology progresses and which company does best in what is a very large energy storage market.

Zero-Carbon Lighting Of Large Spaces

In Cockfosters Train Depot – 12th January 2023, I took a series of pictures of Cockfosters Train Depot, of which these are a selection.

Note, the lamp clusters on top of tall poles to light the area.

You see lots of these lights to illuminate play areas, car parks, rail sidings and truck depots.

Could a SeaTwirl or another vertical wind turbine be placed as high as possible up the pole, that supports the lights?

  • A battery would be needed for when the wind doesn’t blow.
  • A control system would be used to use the lights, when they are needed.
  • The poles would be able to be laid down, like many lights can be, for servicing from the ground.

Cockfosters would be an excellent location for a test, as the wind is always blowing and the site has an altitude of nearly a hundred metres.

National Grid Goes Carbon-Free With Hydrogen-Powered Substation Trial

The title of this post, is the same as that of this press release from National Grid.

These are the main bullet points.

  • Hydrogen powered unit (HPU) quietly provided carbon-free electricity to National Grid’s Deeside Centre for Innovation
  • Only emission is water
  • HPUs could save an estimated 500,000 kg of carbon across all National Grid substation sites

I am an Electrical Engineer and I had never realised that all those electricity substations around the country need a backup electricity generator.

These four paragraphs describe the trial and the generator used.

A GeoPura 250kW hydrogen power unit (HPU) contained within a transportable shipping container measuring 7.2 m by 2.5 m was installed at DCI and produced the energy to power low-voltage equipment needed for National Grid’s innovation testing projects and site operations. The trial tested the capabilities and feasibility of HPUs as direct replacements for backup diesel generators across more than 250 National Grid substation sites, the data will now be analysed and shared later this year.

National Grid currently use diesel generators alongside batteries to provide backup power to a substation for key activities such as cooling fans, pumps, and lighting, enabling it to continue to perform its crucial role in the electricity transmission system.

These backup generators are rarely used and have less than a 1% chance of operating per year, however, on the rare occasion that backup power is required, changing from diesel to low-carbon emission alternatives have the potential to reduce carbon intensity by 90%* and save over 500,000 kg of carbon emissions.

The HPU at Deeside has power capabilities of up to 100 kW in continuous operation mode and up to 250 kW for 45 minutes and uses 100% green hydrogen. The unit is quieter and the hydrogen cannisters used to fuel the generators can be safely stored on site.

I have some thoughts.

Deeside Centre For Innovation

The Deeside Centre for Innovation (DCI), a state-of-the-art testing facility hosting a 400 kV modified substation, designed as a unique environment for development and trial of innovative technologies and practices.

I think there’s something rather cunning about the DCI, as it means that anybody with a good idea will probably approach National Grid for help with the testing.

Visit Deeside Centre for Innovation for more information.

GeoPura

GeoPura has a totally zero-emissions answer to how we’re going to generate, store and distribute the vast amount of energy required to decarbonise our global economies. Or so their web site says!

This page on GeoPura’s web site, gives several case studies of how they work.

They would appear to provide zero-carbon power in widespread locations for Winterwatch, Springwatch etc. for the BBC.

Tevva Starts First Mass Production Of Electric Lorries In UK

The title of this post, is the same as that of this article on Professional Engineering.

These are the first three paragraphs.

Tevva is building its 7.5 tonne vehicles at Tilbury in Essex after it received European Community Whole Vehicle Type Approval (ECWVTA), meaning it can start producing and selling in volume across the UK and Europe.

The start-up has already started delivering its first mass-produced lorries to customers including Travis Perkins and Royal Mail. It expects to sell up to 1,000 in 2023.

Described as “ideal” for last mile and urban delivery fleets, the electric truck offers up to 227km range from its 105kWh battery on a single charge. It will be followed later in 2023 by a 7.5 tonne hydrogen-electric alternative. The hydrogen range extender will reportedly increase the range up to 570km.

That seems like a good start to me; certification, orders for a thousand and generous ranges with or without a hydrogen extender.

In Equipmake Hybrid To Battery Powered LT11, I described Equipmake’s battery-electric New Routemaster bus.

Both the battery-electric Routemaster and the Tevva truck seem to have generous ranges, so has better battery technology been developed.

The Bowes Park And Bounds Green Out-Of-Station Interchange

After I’d taken the latest pictures in Bowes Park Station – 12th January 2023, I walked to Bounds Green station to go back South to the Angel.

I took these pictures on the way.

Note.

  1. The walk is level and could be done easily, if you were pushing a buggy, dragging a case or in a wheel-chair.
  2. There is a footbridge over the busy Bowes Road, which doesn’t have lifts. But you don’t need it to go between the stations.
  3. There is a light-controlled crossing outside Bounds Green station to cross Brownlow Road.
  4. The walk took me about six minutes.

These pictures show the escalators at Bounds Green station.

Could the central stairs be replaced by an inclined lift?

Would This Out-Of-Station Interchange Create An Easy Route Between Northern Piccadilly Line Stations And The Elizabeth Line?

Consider.

  • Cockfosters, Oakwood and Arnos Grove stations have car parking.
  • All stations on the Piccadilly Line from Bounds Green Northwards are well-connected by buses.
  • Bounds Green station has escalators.
  • Bowes Park station has stairs.
  • Bowes Park station has a well-stocked cafe.
  • Moorgate station has escalators and lifts to the Elizabeth Line.

For a perfect route, some things must be done.

The Frequency Of Trains On The Northern City Line

At the moment the trains through the station are two trains per hour (tph) between Moorgate and Stevenage.

But the frequency has been as high as four tph.

The frequency needs to be higher to cut waiting for a train.

Step-Free Access

This needs to be installed or improved at Bounds Green, Bowes Park and Moorgate stations.

Signage

The route between Bowes Park And Bounds Green stations needs better signage.

Conclusion

This Out-Of-Station Interchange could be made more use of.

A Road Scheme That Appears To Going Nowhere

This article on the BBC is entitled A57 Link Roads Mottram Bypass: Charity Seeks Judicial Review.

This is the sub-heading.

Environmental campaigners are seeking a judicial review of proposals designed to ease road congestion between Manchester and Sheffield.

And these are the first two paragraphs.

Plans for the A57 Link Roads Mottram Bypass scheme were boosted in November when Transport Minister Huw Merriman granted a development consent order.

But countryside charity the CPRE said there was no evidence building a new road “moves away a traffic problem”.

I remember this area well from the 1960s, when I was studying at Liverpool University and my parents lived in Felixstowe.

  • There was no motorway across the Midlands between Coventry and Stafford and the alternative of the A5 was a nose-to-tail crawl.
  • The M62 was still in the design phase.

So I took to using this cross-country route.

  • A45 between Felixstowe and Huntingdon.
  • A1 to Worksop, which was mainly dual-carriageway.
  • A57 to Manchester, through Sheffield and Glossop, which was and still is single-track.
  • A580 to Liverpool.

I think my best time was about five hours in a 1954 Morris Minor.

I feel, I must have gone through Mottram in Longdendale, judging by the map on the BBC article.

It is interesting to read the Wikipedia entry for the Longdendale Bypass, which starts like this.

The Longdendale Bypass (also known as the A57/A628 Mottram-in-Longdendale, Hollingworth & Tintwistle Bypass) is a long-planned road scheme in England by the Highways Agency. The aim is to alleviate traffic congestion on the A57 road/A628 road/A616 road routes that presently pass through the villages. There is both support and opposition for this long-planned scheme which will pass through the valley of Longdendale and part of the Peak District National Park.

The scheme was approved by the Highways Agency in 2014, so politicians have not exactly been quick off the mark.

These are some choice phrases from the Wikipedia entry.

  • It is used by a relatively large number of heavy goods vehicles.
  • Supporters of the scheme say that the A628 is one of the most congested A-road routes in the country.
  • There is no viable alternative to a bypass.
  • A survey in 2010 found that the junction of the A57 and M67 was the most congested in Manchester.

It is a disaster and the intervention by the CPRE will further delay a solution.

Conclusion

It is problems like this, that lead me to one solution.

On the one hand, you improve the railways and on the other you bring in universal road charging.

Hopefully passengers and freight will find a happy equilibrium.

But voters wouldn’t like it and any Government, that brought it in would lose the next election to a yet-to-be-formed Motorists Party.

Wind Generation Sets New Record In UK Surpassing 21 GW

The eye-catching title of this post, is the same as that of this article on Renewables Now.

I regard anything over 20 GW as very good, as the UK’s average daily consumption is typically around 23 GW, so surely we can find a couple of gigawatts of biomass, gas, hydro or nuclear.

The Renewables Now article says this about UK electricity generation.

According to National Grid ESO, on Monday, January 9, wind accounted for 50.2% of British electricity, nuclear for 15.9%, gas for 13.1%, imports for 10%, biomass for 4.8%, hydro for 3.8%, solar for 1.3% and coal for 1.1%. Tuesday’s wind record may undergo slight adjustments in expectation of all data for yesterday.

I shall be following these figures.

  • Especially, as Wikipedia says another 3 GW will be installed this year.

But it does seem that we’re getting there with renewable electricity.

A Thought On Energy Storage

I also think that if we are generating large amounts of electricity at times, which are more than we need, then we had better crack on and build lots of energy storage.

If we don’t need the energy and Europe or Ireland doesn’t want it, then we must store it, so that if the wind isn’t blowing we can recover it for a useful purpose, even if it is only selling it to the Germans to make hydrogen, which is used to replenish their stores.

Cockfosters Train Depot – 12th January 2023

In Would A Solar Roof With Added SeaTwirls Work?, I showed this map of Oakwood.

Note.

  1. The striped roofs at the top of the map, with sidings for trains to the North, is Cockfosters Train Depot for the Piccadilly Line.
  2. Cockfosters station is off the map on the West side of the map.
  3. Oakwood station is at the East side of the map and indicated by a London Underground roundel.
  4. The two tracks of the Piccadilly Line between Oakwood and Cockfosters stations, running across the map to the North of the depot.

I took these pictures of the Cockfosters Train Depot as my train went between Oakwood and Cockfosters.

Note.

  1. The land between the Piccadilly Line and the depot seems to be being cleared.
  2. Is this to expand the depot for the new trains?
  3. There are some high lights mounted above the sidings.
  4. The depot buildings don’t look anything special.

This article on Ian Visits is entitled Depot Upgrade At Cockfosters For The Piccadilly Line’s New Trains.

  • Before and after maps show a lot more sidings.
  • The new siding layout reaches almost all the way to the Piccadilly Line.
  • The old depot has been assessed to be utilitarian with low architectural and historic value.
  • The depot will be completely rebuilt over the next two years for the new Siemens trains.
  • Nothing is said as to whether the new depot will be fitted with a solar roof.

The new trains will start running in 2025. It seems that the work hasn’t progressed very far.

Bowes Park Station – 12th January 2023

I’d never used Bowes Park station until I moved back to London in 2011, despite the fact I had friends in the 1960s, who lived nearby.

Today, I was wanting to go from the Northern end of the Piccadilly Line to Moorgate station.

There are a number of ways to do this journey.

  • Piccadilly Line to Bounds Green tube station and then a Great Northern train from Bowes Park station to Moorgate
  • Piccadilly Line to Wood Green tube station and then a 141 bus to Moorgate.
  • Piccadilly Line to Manor House tube station and then a 141 bus to Moorgate.
  • Take the double cross-platform change route, I outlined in Extending The Elizabeth Line – Improving The Northern City Line.

I decided to take the first route.

I took these pictures at Bowes Park station.

Note.

  1. The station has a warm well-stocked cafe, that is an asset to the station.
  2. The station has a defibrillator.

In an ideal world the station would have step-free access, as this would give a step-free route to Moorgate and the Elizabeth Line.

I returned a day later and took these pictures to see if a lift could be fitted.

I don’t think it would be one of the most difficult or expensive jobs to fit in a lift, that took passengers between the platform and the bridge.

The existing stairs would be retained and fitted with a decent fully-compliant handrail.

If a single lift were to be placed on the opposite side to the stairs, passenger access to the station would be possible  during the installation.
