Alstom And Liebherr Sign A Collaboration Agreement, In Order To Optimise Hydrogen Fuel Cells

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

The press release starts with these points.

  • Liebherr is developing air management technology that is particularly well suited to hydrogen fuel cells.

  • Alstom’s hydrogen strategy is part of its ambition to innovate by pioneering smarter and greener mobility solutions for all.

This paragraph then gives the basic outline of the agreement.

Alstom has signed a collaboration agreement with Liebherr – Aerospace & Transportation SAS, a France-based company specialising in the manufacture of compressors for fuel cells. This agreement is aimed at optimising hydrogen systems, including improving the reliability and durability of fuel cells, increasing their power density and reducing the cost of such solutions.

The press release gives a lot more details about Alstom’s hydrogen collaborations with other companies

Alstom seem very serious about hydrogen-powered trains.

‘Box Structure’ Flyover Saves £70m And Six Months For East West Rail

The title of this post, is the same as that of this press release on Network Rail.

This is the first paragraph.

Engineers have saved £70m of taxpayers’ money by using creative new methods to build a railway flyover as part of the East West Rail project.

This Network Rail picture shows how the new flyover rests on a concrete box, that spans the West Coast Main Line (WCML).

Note that the press release contains a video that explains how the flyover was replaced and why the method of construction saved all the money and time.

The main cost savings came about because of the following.

  • Construction could go on above the WCML without having to stop the trains.
  • Components for the flyover were made in a factory, with subsequent cost reductions and quality increases.

Anybody, who’s ever poured a concrete slab in typical British weather will understand the second point.

According to the press release, the method of construction gives a hundred and twenty year life span for the structure.

For comparison, this 3D Google Map visualisation shows the Hitchin flyover, which was opened in 2013.

Note the columns supporting the single-track railway.

If this was being built today, would a box be used as at Bletchley?

Will JCB Dig The Whole World Out Of A Hole?

JCB and the Bamford family in general have form, where hydrogen is concerned.

  • JCB have developed internal combustion engines, that will run on hydrogen.
  • Jo Bamford owns Wrightbus and they are building hydrogen-fuelled buses in Northern Ireland.
  • JCB were an early investor in hydrogen electrolyser company; ITM Power.
  • JCB have signed a large contract for the delivery of hydrogen with Fortescue Future Industries.

I have just watched this amazing video, where Lord Bamford explains his philosophy on hydrogen.

How To Build A Liverpool-Style Optical Bench

When I worked at ICI in Runcorn, one of the guys had developed a very accurate instrument for measuring trace chemicals in a dirty process stream. I remember one of these instruments was used to measure water in parts per million in methyl methaculate, which is the misnomer or base chemical for Perspex.

All the optical components needed to be mounted on a firm base, so a metre length of nine-inch C-section steel beam was chosen. The surface was then machined flat to a high accuracy.

In the end they found that instead of using new beams, old ones decades-old from the depths of a scrap yard gave better accuracy as the steel had all crystallised out. Machined and spray-painted no-one knew their history.

But they were superb instruments and ICI even sold them abroad.

How Clean Energy And Jobs Can Flow From Morocco to The UK

The title of this post, is the same as that of this article in The Times.

  • The article has been written by Simon Morrish, who is the founder and CEO of Xlinks.
  •  The article is about his plans to build a 10.5 GW solar and wind power complex in Morocco and connect it to the UK, by an undersea power cable running up the coasts of Morocco, Spain, Portugal and France.
  • This page on the Xlinks web site gives details of the project.

These are some points from the article.

Relationship With The Exchequer

He makes these points about the projects relationship with the Exchequer.

  • The company will be a net contributor.
  • The project will not require government subsidy of finance.
  • Energy will be delivered under the Contract for Difference (CfD) price of £48/MWh.
  • This compares with a CfD price of £92/MWh for Hinckley Point C.

Simon Morrish also claims they will be energised before Hinckley Point C.

That sounds good to me.

Finance

I wonder if at the CfD price quoted in the  article, could this mean that this is a project that could be financed in the City of London or from a Sovereign Wealth Fund?

As Simon  is confident the project can be completed before Hinckley Point C, I suspect that the finance might be in place, even if it hasn’t been signed off.

The 20GWh/5GW Battery

Simon says this about the battery.

Alongside the consistent output from its solar panels and wind turbines, a 20GWh/5GW battery facility will ensure power generated can be delivered every day, resulting in a dedicated, near-constant source of flexible and predictable renewable energy, designed to complement renewable energy generated in the UK.

In Moroccan Solar-Plus-Wind To Be Linked To GB In ‘Ground-Breaking’ Xlinks Project, I forecast that the battery would be from Highview Power, but given the delivery date before Hinckley Point C, I would suspect that Xlinks have a battery supplier in mind.

Employment Benefits

Simon says this about employment benefits.

Thousands of jobs will be created in Morocco and also at home.

If the project goes ahead, given its size, I don’t think many would disagree with that.

Simon also claims the project will create 1350 permanent jobs by 2024. Sites mentioned include Hunterston, Port Talbot and the North East of England.

Simon’s Conclusion

This is Simon’s conclusion about the project.

I love the idea of clean electricity flowing, all the way from Morocco to the UK. I hope it may inspire other ambitious renewable energy projects too — which, together, will provide clean, secure and stable energy, at affordable prices, for businesses and households to rely on and help to protect this special planet.

If you can, I suggest you read the full article on The Times.

Conclusion

The more I read about this project, the more I tilt towards it being feasble

Engineering is the science of the possible, whereas politics is dreads of the impossible.

Mott’s £6m Plan Approved For Hammersmith Bridge

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

This is the introductory paragraph.

Hammersmith & Fulham Council has approved a new plan to stabilise Hammersmith Bridge at significantly below the original expected cost, with works completing in less than a year.

Consulting engineer, Mott MacDonald have developed a solution to the bridge that is simple in the extreme.

This sentence describes the principle at the heart of the solution.

The Mott MacDonald solution involves the use of elastomeric bearings, which allow any pressure to be applied equally to all four corners while protecting the vulnerable 134-year-old cast iron structure.

There would also appear, that some very serious computing has been applied to allow the new bearings to be inserted, by just jacking up the bridge.

In addition to the cost and the speed of installation, the Mott MacDonald plan has been welcomed by Heritage England, will require less closures and doesn’t involve diversion of the gas main.

Conclusion

This intervention will stabilise the bridge and give time for a long-term solution to be developed, that will allow the bridge to be opened to vehicles.

BECCS Beats Hydrogen For Decarbonizing Steel In Europe: ArcelorMittal

The title of this post, is the same as that of this article on S & P Global Platts.

This is the first paragraph.

Bioenergy with carbon capture and storage (BECCS) offers a more cost-effective, readily available solution for decarbonizing the steel industry in Europe than clean hydrogen, steel producer ArcelorMittal’s head of strategy David Clarke said May 17.

So what do they mean by bioenergy?

To make iron from iron ore, you need a reducing agent like carbon or hydrogen.

Iron ore is rich in oxides of iron.

The carbon is usually some form of coal, which produces large amounts of carbon dioxide with the oxygen from the iron oxides.

Hydrogen produces lots of water with the oxygen.

David Clarke of ArcelorMittal explains the process in the article.

“We know biomass worked as a replacement for coal,” he said. “We’ve been using it in our operations in Brazil and other places for many, many years. We have a project in Belgium that we’ll be starting up next year using waste wood, using that to make bio-coal,” with a project to take the emissions from the bio-coal to produce bioethanol.

Is this a case of Back-To-The-Future? If I remember my history, didn’t Iron Age men use charcoal to smelt iron and other metal ores?

If those scientists from Velocys can make Sustainable Aviation Fuel and biodiesel from household waste and used disposable nappies, can they apply their magic to make bio-coal?

I see great cost advantages with this process, as surely it would enable existing blast furnaces to be used, provided they were fitted with carbon capture and storage.

Alternative Energy Storage Technologies To Challenge Electrochemistry

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

It gives a good summary of two energy storage system; Highview Power and Gravitricity, that I rate highly promising.

It also gives details of a Danish system called Stiesdal Storage Technologies, which is developing a hot rocks energy storage system.

The article says this about the system.

The pumped-heat ESS uses pea-sized crushed basalt, rock in insulated steel tanks with the stored energy released by turbine.

SST CEO Peder Riis Nickelsen said: “The cost of crushed stone is at a totally different level per unit of energy than practically any other material for energy storage. Our charging and discharging system can utilise well-known technologies that have been applied for a century within other industries and are well-suited for mass production.”

The cost of materials is estimated to be €10 ($12) per kWh.

The first demonstration project, a 1-2MW, 24h capacity unit, will be installed at a power plant in Denmark next year, and will operate commercially.

This page on the Striesdal web site, explains the technology.

It sounds like the system uses very similar principles to Siemens Gamesa ETES, with a different heat storage medium.

Conclusion

At my last count, there now appears to be upwards of half-a-dozen viable alternatives to chemical batteries and traditional pumped storage. Some of the technologies are also backed, by large companies, organisations and countries, who can afford to take a long-term view.

I hope those, who claim that renewables will never power the world, have at least got the recipe for the cooking of humble pie ready.

MAN Energy Partners With Highview Power On Liquid-Air Energy-Storage Project

The title of this post, is the same as that of this article on Renewable Energy Magazine.

This is the introductory paragraph.

Highview Power, a leader in long duration energy storage solutions, has selected MAN Energy Solutions to provide its LAES turbomachinery solution to Highview Power for its CRYOBattery™ facility, a 50 MW liquid-air, energy-storage facility – with a minimum of 250MWh – located in Carrington Village, Greater Manchester , U.K.

The article is almost a word-for-word copy of this press release from MAN Energy Solutions, which has a similar title to this post and the Renewable Energy Magazine article.

As an Electrical Engineer who has done a lot of work in Project Management, I find these two paragraphs significant.

Construction will proceed in two phases. Phase 1 will involve the installation of a ‘stability island’, to provide near-instantaneous energy grid stabilisation. This will be achieved using a generator and flywheel, among other components. Enabling short-term stabilisation will provide the basis for Phase 2 and the completion of the more complex liquid air energy storage system that includes various compressors, air expanders and cryogenic equipment.

Phase 2 will represent the integration of stability services with a full-scale long-duration energy storage system, and in doing so promote the full integration of renewable energy. The Carrington project will offer a blueprint for future projects and cement the partnership between MAN Energy Solutions and Highview Power.

I first became acquainted with the use of flywheels to stabilise energy, when I was working in Enfield Rolling Mills as a vacation job at sixteen.

The centerpiece of their factory was a rolling mill, which took heated copper wirebars about two metres long  amd ten centimetres square and rolled them into thick copper wire just a few millimetres in diameter. The mill was driven by a powerful electric motor, to which it was connected with a 97 tonne flywheel perhaps four metres in diameter in between. The flywheel spun at probably 3000 revolutions per minute.

The wirebar used to meander through the rolling mill several times and at each turn, the head would be caught by a man with a pair of tongs and turned back through the mill.

Each time the wire-bar went through a new pair of rolls the energy needed increased, as there was more rolling to do. So this extra energy was taken from the flywheel!

The rolling mill incidentally had been built by Krupp before the First World War. It still had the Krupp trademark of three interlocked railway tyres all over it. It had ended up in Enfield as reparations after the First World War. Enfield Rolling Mills added a fourth ring to create their own trademark.

It would appear that the kinetic energy of that flywheel could be as high as 1.6 MWh. Flywheels also react very fast.

Flywheel energy storage would appear to be a feasible intermediate energy store for this type of application.

I always remember Shimatovitch, who was the Chief Engineer of the company had jokingly once said that if the flywheel came off its bearings, it would have ended up a couple of miles away and would have demolished all the houses in its path. But he was a man with a dark sense of humour, who had spent most of the Second World War in a Nazi concentration camp.

Could it be that Phase 1 is the installation of a similar system to that I saw working in the 1960s, but upgraded with modern electronics, which exchanges power with the grid to create the stability island referred to in the press release.

In Phase 2 electricity can be passed to and from the CRYOBattery.

Looking at the MAN Energy Solutions web site, I suspect that they don’t care what sort of energy store they connect to the grid.

They would appear to be an excellent choice of engineering partner for Highview Power.

I also wonder how many other applications and customers, they will bring into the partnership.

Conclusion

This looks like a very sensible and low-risk strategy to connect the CRYOBattery to the grid.

Velocys Signs Agreement For Commercial-Scale Biomass-To-Jet Fuel In Japan

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

I am very hopeful about Velocys, who are a UK public company, that were spun out of Oxford University and do clever things in the area of chemical catalysts.

Velocys’ Fischer-Tropsch technology does seem to be a good way of creating sustainable aviation fuel from household rubbish and biomass.
