Critical Minerals: Domestic Production

Debate between Luke Myer and Perran Moon

Tuesday 3rd December 2024 Westminster Hall

[Perran Moon (Camborne and Redruth) (Lab)]

I beg to move,

That this House has considered the domestic production of critical minerals.

It is a pleasure to serve once again under your chairship, Mrs Harris. I am pleased to have secured this debate on a subject that I believe is yet to achieve the public and pollical prominence that it deserves, but that is fundamental to the UK’s energy transition, economic security and industrial growth—especially in areas of high deprivation.

What are critical minerals? Strictly speaking, critical mineral is a label given to materials that are deemed to have economic value and that are vulnerable to supply chain insecurity. The term was first used by the United States Government in the 1940s to describe materials crucial to military technologies. In our modern economy, transitioning to net zero to mitigate the existential threat that we all face from climate change, the new generation of critical minerals such as tin, lithium and tungsten are crucial as the global economy shifts from a fossil fuel intensive to a material-intensive energy system. Last week, the British Geological Survey published its critical minerals list, finding 34 different materials crucial to our economy.

My hon. Friend mentions the critical minerals list; it is my view that the list needs to evolve to keep up with the increasing demands that we face, and to account for the production of minerals that we have in this country. In my part of the world we produce polyhalite, a fantastic crop nutrient fertiliser that has huge potential for our food security. Would he agree that the critical minerals list needs to account for minerals such as polyhalite, so that we can ensure our economy is growing into the future?

[Perran Moon]

It is essential that there is an ongoing dialogue about the critical minerals list. I attended a conference yesterday with the British Geological Survey, at which it explained how it came up with the critical minerals list. My hon. Friend is absolutely right that we need to focus on those minerals that are crucial to the development of our economy. Those minerals are essential for our batteries, cars, wires, consumer devices and defence applications.

To be clear, critical minerals are the cornerstone of the clean energy revolution—the lifeblood of electric vehicles, wind turbines, solar panels and cutting-edge electronics. In a world where demand for technology grows ever stronger, critical minerals stand as both our greatest challenge and our most brilliant opportunity. Demand is set to massively increase over the next few years and decades, as more consumers buy electric vehicles powered by renewable energy.

I have framed critical minerals as a great challenge as well as an opportunity. That challenge arises because at the moment the UK imports almost all of its critical mineral demand. A number of countries dominate the upstream supply chains, with the top three nations dominating well over three quarters of global output, according to the International Energy Agency. That concentration of production is even higher when it comes to refining operations, where China dominates. By 2030, 85% of lithium will be refined in just three countries. That level of supply chain domination is distinctly undesirable for our decarbonising economy and is much higher than the production concentrations of fossil fuels.

We must diversify our supply chains to achieve greater resource security, including the development of domestic production capabilities. Other large economies such as the US, Canada, Australia, and the EU are working to secure their own critical mineral supply chains, and we must not be left behind in the race to supply security.
