There is a respectable peacetime economic case for closing the Port Talbot blast furnaces and ceasing production of basic oxygen steel (BOS) in the United Kingdom and it is set out by the leading trade economist Catherine McBride. She shows how much British steel-making of any type has declined by volume, and how chronically dependant what remains is upon imported raw materials. She also explains how much EAF – electric arc furnace – steel production from recycled scrap has increased worldwide: for example, 70% of American steel in 2022 came from that source. Finally, she shows how globally dominant China and India have become in BOS, as witness 90% of China’s 1 billion ton steel production in 2022. China and India have massive economies of scale, and also access to domestically controlled raw materials, giving end-to-end control: in the Chinese case, both coking coal and iron ore, and in the Indian case, iron ore but with need to import coking coal. In contrast, the UK currently has to import both ore and coking coal at scale to feed the condemned blast furnaces.
While neither of the Asian giants exports much primary steel – in the Chinese case, only 40 million of 1 billion tons produced – both are major suppliers of steel products. The UK buys more steel products from China than from anywhere else, and therein begin the problems. ‘While the UK doesn’t matter to China, China matters to us,’ McBride observes sharply.
There is an unrespectable case for closing the Port Talbot blast furnaces and replacing them with Electric Arc Furnaces. It is the one which the government supports and, with a half billion pound bung, proposes to pay Tata Steel to effect: you can be sure that they wouldn’t do it otherwise. This is the claim of some contribution on the fantasy road to ‘Net Zero’ where the harder you try the more you fail.
However, in two major reports, the iron and steel trades unions have blown that alleged ‘Net Zero’ gain out of the water, pointing to the obvious: BOS steel not produced in Port Talbot will be produced elsewhere and imported to this country. So there is zero reduction to global carbon dioxide emissions and there is the addition of emissions from ocean transport. Without pig iron, there is also loss of full-spectrum virgin steels capability, loss of high quality jobs and the social devastation of lives in South Wales. The unions’ plan is on the right side of history and should simply go further: ignore the ‘Net Zero’ targets and focus, on national security grounds, on securing a domestic balance of BOS and EAF production. France and Germany both have a 70/30 split, for example. The unions plainly understand the industry better than any civil servant or think tank genuflecting to Net Zero targets.
Therefore, this is the moment when the music stops. The Port Talbot closure harshly exposes the costs of luxury ‘green’ beliefs as we enter the second phase of a global war. It is a war of different theatres and modes of conflict: simultaneously ‘hot’ (kinetic) in Ukraine, the Middle East and with Taiwan threatened; ‘cold’ (economic) with China, Russia and Iran; and ‘grey’ (psychological, cyber and subversive), with all the enemies of the Free World. Major recent statements by NATO’s Military Committee chairman, the Head of the Army (and Norwegian and Swedish CDSs) and the Defence Secretary finally inform the public of these inconvenient facts. This is no drill.
These concerns touch upon the question of Port Talbot directly and add to the many powerful objections to the closure decision. It must be reversed – we cannot be dependent on imports for the full range of necessary steels to rebuild our arsenals – the Navy first and foremost – and most ridiculously, we cannot be dependent for them on our global antagonists. China’s coal-fired economy is why it can readily build its new navy, just as we once did and must again.
Catherine McBride’s primary argument for replacing BOS steelmaking with EAF is concern about reliance on imported strategic raw materials. However she also observes that UK electricity costs are among the most expensive in the world and this destroys the case for EAFs as well, or for any unsubsidised steel production in the UK at all. EAFs require abundant and stable electricity supplies, such as they have in the USA. And the cause of the UK’s crippling electricity price? Net Zero. So the issue is not BOS versus EAF steel: it’s Net Zero’s all pervasive toxicity, poisoning UK power generation.

In our ‘pre-war’ world, what must change? First secure the grid. With news of delays to Qatari LNG shipments, upon whose regular arrival at Milford Haven we depend, UK grid security and stability are left dangling precariously on two threads: interconnector imports and undersea gas pipelines, which the Russian Navy’s Special Submarine Operations force (GUGI) could easily interdict. All offshore infrastructure with supply pipes and wires are similarly vulnerable, of course. However, gas is dangerously central to our energy security, given that uncontrollable wind and solar simply destabilise the grid – beware the Dunkelflaute my beamish boy! Therefore grid security has to be assured, mainly by the only large remaining firm power source, combined-cycle gas turbine (CCGT) power stations. The UK’s main gas storage site at Rough, which re-opened in 2022, has been doubled in capacity to 54 billion cubic feet of gas in 2023; but the obvious step of permitting Bowland Shale fracking remains blocked.
Therefore, by elimination, there is only one broad highway to safety. It is to follow Germany, erstwhile home of deep green eco-politics, which, in a hard-headed way after the disaster of the Energiewende, is moving back to coal – yes coal – but not coal as you think you know it. Advanced ultra super-critical technology (AUSC) is clean coal that achieves close to 50% thermal efficiency.
In tandem, we must also fix our import vulnerabilities in coal and iron ore. Take a deep breath as that reality hits home.
For the UK, this means re-opening South Wales premium hard coal and Nottingham deep mines, because we need domestic supplies both to power the grid cheaply and reliably once more – no form of nuclear will be made ready quickly enough, while GE’s AUSC plants are available today. (We will also need Cumbrian metallurgical coal to supply Port Talbot, so we can still have the full range of virgin steels.)
CCGTs can then be retired from base load, and take on a supporting role as peaking power, as such a high-quality fuel should be used. We shall need to re-engage the wartime mentality of strategic stockpiling; and thank goodness that Sweden, currently on the threshold of entering NATO, will be on our side this time in terms of iron ore exports, unlike during the Second World War.
Recognising the strategic risk in renewables’ fragility leads to the inevitable conclusion that subsidy plugs and bungs – like the one given to Tata essentially to compensate for electricity costs driven uneconomically high by Net Zero, so it will build EAF at all – must be pulled.
‘And what of our CO2 targets?’, many outraged voices may wail. ‘What of Net Zero?’, the subject which is on every lip but which few understand? The music stops there too. Now that we can explain why the Hansen 1988 ‘control knob’ CO2/global temperature close-coupling hypothesis doesn’t hold, which is the major finding of thirty five years of global climate systems research, but instead is vitiated by two fundamental errors in its theory of knowledge and by a major technical error by the IPCC (see Archimedes’ Fulcrum pp. 9-13), we can more accurately assess the risks from anthropogenic CO2 emissions to global security, relative to other risks, and adapt to them. As ‘wicked’ problems, they cannot be mitigated because there is no sufficient understanding of cause and effect. Outside the closed belief-systems of eco-zealotry, in the real hard world of geopolitics, anthropogenic CO2 risks rank pretty low and, for our adversaries, not at all. They weaponise our ‘green’ thinking against us.
The reversal of the Port Talbot blast furnace closure on national security grounds, a return to domestic coal for power and for steel, pulling the subsidies plug on renewables-that-are-not, and jettisoning of Net Zero targets – so glibly conjured into being on the back of shoddy data, and unthinkingly nodded into law to give Mrs May a semblance of a ‘legacy’ – will be the signal that reason and clear-thinking have returned. We shall once again have economics as if the defence of the Realm, the wealth and health of its citizens, and indeed the health of the environment too – which is no paradox – really mattered. That true environmental visionary E.F. Schumacher was never apologetic about his career with the National Coal Board. No more should we be about clean coal now, as the noises of eco-zealotry in the isle subside and we awaken as if from a dream.
As you from crimes would pardoned be, let your indulgence set me free.

WOW! Thanks for this TB.
I concur with many of these disclosures.
Kind regards, Ray Dart (AKA suricat).
For an supposedly experienced person in energy and politics, it appears that the professor has little knowledge of industry in Asia. China, Japan, South Korea and Taiwan import almost all their iron ore and metallurgical coal from Australia. China does not have very good quality resources of iron ore while Japan, South Korea and Taiwan have none. The vast amount of coal in China is not suitable for iron & steel production. That is why they import coal. India has poor quality coal that is not efficient in iron and steel production. That is why they also import coking coal from Australia. UK would be better off importing iron ore and metallurgical coal from Australia. Back around 1986 I was in UK trying to interest the Blue Circle cement group in importing coal from our Blue Circle associate in Australia. I visited the Blue Circle plant at Northfleet just after Margret Thatcher had visited (another sorry how she was more technically competent than any director of Blue Circle). We could have landed coal at Northfleet for half the price that they were obtaining from the NCB plus rail freight. They used our offer to get a 10% discount from the NCB. It is no wonder the Blue Circle group got into financial problems and sold everything around the world. UK now imports cement with foreign based companies owning most of the local production.
UK management, unions and poor politics (eg entry into the EU common market and the stupid energy Act) are the major reason for the decline of the UK.
Prins: There is no ‘green transition’ backwards from dense stocks to thin flows of energy – nor can be – and it would make no difference to global climate systems if there were; but attempting to achieve one by legislated coercion leads to environmental, social and economic mayhem.
The harder Net Zero is pushed, the more it fails.

The heat pump climb down is another nail in the Net Zero coffin
Politicians can set targets day and night. But if they fail to consider the consequences, embarrassing u-turns will inevitably follow
ROSS CLARK 5 February 2024
But what we have seen so far is only the beginning. Over the next few years we are going to see many more of these targets having to be relaxed, delayed or abandoned – including, I don’t doubt at some stage, the holy grail of net zero itself. It is just that it is going to be a long and painful political journey to get there.

The unholy grail.
Thanks to Cat for his likes. I do not know how to do that. I like the idea of green up thumbs and red down thumbs as with WUPT and Jonova.
Oldbrew, I tried to read Prof Prins pdf but had to give up. Too verbose, and public servant and academic elitist type writing. No explanation of technical facts and measured engineering theory (such as the 2nd law of thermodynamics and heat transfer), no factual explanation of economic considerations.
I suggest the only politician in UK who has some grasp of technical facts and economic issue is Nigel Farage.
Many people do not know that cement and steel production per capita are lead indicators of GDP (gross domestic production) per capita. Cement production per capita in the UK has gone down (also in USA), now under 250kg/capita . China, Japan, Singapore, South Korea, Saudi Arabia, UAE and Veitnam have reached more than 1 tonne cement/ capita. India is rapidly increasing cement production but only just over half of China. Indonesia is also rapidly increasing cement production but still behind India.
UK should not have gone into the European Common market and stuck with the Commonwealth. They now should be looking at free trade with the likes of India, Singapore, Australia, Nigeria, Canada and even dealing with Pakistan, Cyprus and maybe even look to Burma (to avoid Chinese developments there)
