Sense About Steel

This article in the South Wales Evening Post is entitled Swansea Bay Tidal Lagoon one solution to Tata Steel crisis, insists council chief Steve Phillips.

He is right and I said so in The Death Of Traditional Steel-Making.

I also said that in addition to the tidal lagoon, a comprehensive metro should be developed all over South Wales.

The Death Of Traditional Steel Making

If we’re being serious about making steel using the traditional methods of blast furnaces, converters and lots of energy, it’s not a very green process and it contributes to pollution and global warning.

We have a serious oversupply of steel in the world and this page lists production by countries.

In 2014, the world produced 1670 million tonnes of steel, of which we produced just twelve.

Looking at the production levels, there are quite a few countries that produce produce small numbers of million tonnes of steel like we do.

As China produced 822 million tonnes of steel in 2014, how many of these countries will be forced out of steel making in the next few years?

What will save steel making in a lot of countries is improvements in technology.

The parts of the steel industry, that seem to be the most profitable are the downstream uses of the metal, like making rails for railways. In this country, we have a reputation for using steel in innovative ways, but few of these uses need steel made in Britain, although they may need a quality steel to start with.

But that quality steel can come from anywhere with the knowledge to produce it.

China will acquire that knowledge, just as the Japanese did in the 1950s and 1960s.

It is interesting to look at iron ore by country in 2014. Out of a world product total of 3.22 million tonnes, we see.

  • China – 1.5 million
  • Australia – 0.66 million
  • Brazil – 0.32 million
  • India – 0.15 million
  • Russia – 0.1 million

So does this partly explain China’s massive production of steel?

I think Australia and Brazil are the two most important countries on this list. Both have large amounts of energy and because they are ambitious intelligent countries, as the steel-making technology develops, will we see them increasingly becoming makers of quality steel?

I don’t know, but it says to me, that even producing quality steel in a niche market won’t be profitable for long.

The money and employment is in using quality steel, not in making it.

It may be a hard unpopular view, but we should let the rest of the world fight over supplying us with quality steel. If we want security of supply, I’m sure the Aussies would provide it.

As to the steel-making areas like Teesside and South Wales, we have to move on.

The Future On Teesside

In fact Teesside seems to be doing that, if a BBC report this week wasn’t truly negative.

What puzzles me about Teesside, is that there is little mention in the media about York Potash. This is from Wikipedia.

The project intends to mine the world’s largest deposit of polyhalite – a naturally occurring mineral – located on the Yorkshire coast.

The mine site is located outside the village of Sneatonthorpe, between Whitby and Scarborough in North Yorkshire. The project plans to construct two 1,500 m (4,900 ft) shafts to reach the mineral seam which includes a mineable area of around 25,200 hectares (62,000 acres).

To minimise the amount of visible infrastructure within the North York Moors National Park, a protected area, the polyhalite will then be transported 37 kilometres (23.0 miles) in an underground tunnel to the company’s processing plant at Teesside. After granulation and drying, the finished product – marketed by Sirius Minerals as POLY4 – will be exported from the nearby harbour facilities.

Could it be that, this project appears to not be very green and in the minds of many is creating a giant hole in the North York Moors National Park?

My view is that the UK needs more big projects like York Potash, that earn billions of pounds from exports, create thousands of jobs and don’t despoil the environment.

The Future In South Wales

So what have we got for South Wales and Port Talbot in particular?

Nothing as big as York Potash, but there are plans for the world’s first tidal lagoon power station in Swansea Bay Wikipedia says this about the Tidal Lagoon Swansea Bay.

It is planned to be the first of six tidal lagoon power plants to be constructed in the United Kingdom, and one of four planned to be built in Wales. The tidal lagoon would have a capacity of 320 MW.

The project was named as part of the UK government’s 2014 National Infrastructure Plan and was granted planning permission by theDepartment for Energy and Climate Change in June 2015. Power production is expected to begin in 2019. The operational life time of the artificial lagoon is 120 years, effects of global warming have been included in the planning. It is also to be constructed to withstand 500-year-storms and to function as a coastline protection against storms and floods.

So what are we waiting for?

The economics depend very much on the strike price for electricity generated and the Government seems reluctant to set one. I do wonder if they have got themselves tied in knots with trying to build a white elephant at Hinckley Point, that they can’t think of anything else.

Consider.

  • I’m not against nuclear power, but Hinckley Point C is so expensive and its strike price is so high, that it will be a millstone around the necks of energy users for decades.
  • If we want to go nuclear, there are smaller and proven reactor systems available.
  • Electricity generation is going more distributed with the growth of solar panels, local heat and power systems and other technology.
  • Large energy users are changing technology to cut use.
  • The tidal lagoon technology gives protection against storms and floods.
  • Tidal lagoons could be the twenty-first century equivalent of the nineteenth-century seaside pier.
  • If the technology and economics of the tidal lagoon work, it will produce carbon-free electricity for at least 120 years.
  • There are other places, where tidal lagoons could be built.

You could bet your life on the Dutch building a tidal lagoon, but they don’t have the tides.

Rather than back a doomed steelworks, the Government should back the unique energy project of the Tidal Lagoon Swansea Bay.

If the energy economics don’t work out, you still get the coastal protection and leisure facilities.

A Metro For Teesside

The Tees Valley Metro has been in planning mode for some years and I can’t understand why it hasn’t happened yet.

All that seems to have happened is the opening in 2014 of James Cook University Hospital station, which I wrote about in James Cook Station – The Reinvention Of The Halt. The station certainly seems to be attracting a level of use, typical of a station of its type.

I also wrote about the metro in The Creation Of The Tees Valley Metro.

A Metro For South Wales

The Welsh are also keen to create a South Wales Metro for some time. I wrote about my observations on the trains in the area in The Welsh Could Be Having A Lot Of Fun Playing Trains In The Cardiff Valleys.

This project should be beaten into action as soon as possible.

It is interesting to take a look at a Google Map of the coast between Swansea and Port Talbot.

Swansea To Port Talbot

Swansea To Port Talbot

I don’t know the area well, but I know many people, who have enjoyed leisure time spent all along the South Wales Coast.

Perhaps, if the steelworks were to be closed, it could be treated to a Barcelona solution, where their steelworks was closed and the area turned into beaches and parks, which formed part of the Olympics in 1992.

The Tidal Lagoon Swansea Bay would be generally sitting in the western part of the bay.

I believe that a comprehensive South Wales Metro, could go a long way to creating more jobs, than will be inevitably lost at Port Talbot.

Conclusions

Steel production is virtually dead in the UK and we must move on.

If we can find an innovative project to replace steel making, we should back it and as with York Potash, it doesn’t necessarily mean billions of public money.

But decent infrastructure and local rail, tram and bus systems can go a long way to creating the jobs needed everywhere.

In both the examples of Teesside and South Wales, surely if nothin else, a decent metro would give a boost to tourism.

Swansea Tidal Lagoon In The Independent

I have a feeling that the Swansea Tidal Lagoon could be a very worthwhile way of generating electricity.

Today, there is this article in the Independent entitled Swansea’s tidal lagoon project delayed amid concerns over costs.

It is a comprehensive review of the technology and contains some interesting nuggets.

  • The Swansea scheme has a capacity of 320MWh
  • The company is saying up to five other places could have a lagoon power station and together they would develop eight per cent of our electricity.

But to me, its biggest advantage, is once it is built, with maintenance, it will continue to produce zero-carbon energy for a long time.

I shall be watching this project with a lot of interest.

Does Jeremy Corbyn Really Support Coal?

I am very surprised by this report in the Daily Mirror, which talks about Jeremy Corbyn and coal. Here’s the first paragraph.

Jeremy Corbyn could bring back coal mines despite vowing to ‘keep fossil fuels in the ground’.

The article goes on to talk about carbon capture technology to burn coal without producing any carbon dioxide.

I have been to learned lectures on this technology and there’s about as much chance of making it work economically, as landing an astronaut on the Sun.

I may be wrong about carbon capture technology, but we would be better spending the investment on insulating our woefully energy-inefficient buildings, so everybody had a lower energy bill.

We obviously need more electricity and there are better ways of generating it without the carbon problem.

My preferred methods would be.

  1. Importing electricity generated by geothermal and hydroelectric power stations in Iceland using an undersea cable. The so-called IceLink is described on this page on the National Grid web site.
  2. Tidal power in the Severn and other western estuaries. The Swansea Bay Tidal Lagoon is a project that has started.
  3. Offshore wind and wave.
  4. Solar panels on buildings. Technology is improving and costs are falling.
  5. Local energy generation using small-scale systems like the Bunhill Energy Centre in Islington.

I also believe that if we funded research in our best Universities, we could fundamentally change our energy use, generation and conservation.

We might even be able to do without using more of the following types of power generation in the future.

  1. Coal, with all its problems of pollution and the carbon dioxide it generates.
  2. Nuclear, with all its problems of high cost and unacceptability by certain sections of the population.
  3. On-shore wind, with all its visual intrusion.

I think the future is going to be scientifically green.

I suspect that in twenty or thirty years time, our main uses of fossil fuels, like oil and gas, will be in the production of needed chemicals, heat energy for industrial processes and powering transport.
