Ever for the reason that Worldwide Vitality Company (IEA) launched its seminal Vital Minerals in Clear Vitality Transitions report in 2021, securing power transition minerals provides has been a significant focus of governments, assume tanks and teachers.
Analysts resembling Kingsmill Bond, a senior principal at assume tank RMI and senior advisor at Carbon Tracker, have made the purpose that the mineral necessities to run fossil applied sciences will all the time be far bigger on a lifetime foundation. Nonetheless, securing the power transition minerals for an enormous scale-up of low-carbon expertise undeniably represents a profound problem. A normal electrical car (EV), for instance, requires six-times the amount of minerals to be constructed as a standard automobile, says the IEA, whereas an onshore wind plant wants 9 instances extra mineral sources than a pure gas-fired plant.
Financial turmoil stemming from the Covid-19 pandemic and world provide chain disaster has created crucial minerals provide challenges within the brief time period, which in flip has had a real-world affect on the rollout of unpolluted applied sciences.
A method of understanding the world’s present minerals problem is by how the costs of power transition minerals have elevated over that interval, which displays how world provide chains have struggled to maintain up with demand.
Under, Vitality Monitor tells this story utilizing mineral value information from the Worldwide Financial Fund (IMF) and US Geological Survey (USGS) to trace the minerals the IEA defines as “crucial” for sure low-carbon applied sciences.
The hovering value of crucial minerals
The largest mineral requirement within the wind trade is for metal. Nonetheless, given the ubiquity of metal manufacturing websites globally, in addition to the truth that vital scrap metal recycling streams exist already, metal will not be outlined as a “crucial” mineral. As a substitute, the “crucial” minerals wanted to construct an offshore wind turbine are chromium, copper, manganese, molybdenum, nickel, uncommon earth metals and zinc, in response to the IEA.
An offshore wind turbine requires a better quantity and number of minerals than an onshore turbine, so referencing this mannequin ensures the evaluation is extra reflective of the broad mineral necessities of the trade.
The worth of every of those metals elevated considerably between January 2020 and March 2023, starting from a 23% value enhance for zinc to a 285% value enhance for molybdenum (which is presently present process a “good storm” of provide and demand disruptions). The common value enhance of those seven metals over the interval is 93%.
The “difficult financial setting” going through the wind trade signifies that in 2022, the 78GW of wind energy capability added globally was the bottom stage previously three years, in response to the International Wind Vitality Council.
Seperate Vitality Monitor evaluation has proven that the value of 1MW of wind capability has elevated by 38% in two years (the results of elevated labour and delivery prices, in addition to uncooked supplies like crucial minerals).
The important thing minerals required in photo voltaic PV are silicon – for the photo voltaic module itself – in addition to copper, nickel and zinc, in response to the IEA. As of March 2023, silicon has recorded the very best value enhance, at 92% since January 2020, whereas the typical value enhance throughout these minerals is 55%.
In line with trade group SolarPower Europe, fluctuating mineral costs have had a real-world affect on the value of putting in photo voltaic PV. The pattern was significantly noticeable in late 2021 and early 2022 as hovering photo voltaic PV demand got here up towards decrease mineral manufacturing volumes initiated throughout the pandemic.

“Final yr photo voltaic module costs had been greater than standard attributable to will increase in polysilicon costs, however between August 2022 and January 2023, as big quantities of recent provide got here on-line, costs dropped,” a SolarPower Europe spokesperson advised Vitality Monitor. “So we are able to see the market rapidly responding to a few of these key bottlenecks and the stability of provide and demand.
“Elsewhere within the worth chain – the copper trade will inform you they’re going through challenges. If not addressed, that can ultimately affect widespread electrification and the power transition.”
In line with the IEA, nuclear energy is – together with hydropower – one of many low-carbon applied sciences with the bottom mineral intensities. Whereas uranium costs are presently greater than twice as excessive as they had been at first of 2020, this metallic will not be included on this evaluation as it’s a gasoline reasonably than a mineral required for tools manufacturing.
Key minerals wanted for nuclear embody chromium, nickel, manganese and yttrium, which is classed as a uncommon earth metallic. The costs of crucial minerals required in nuclear energy have elevated by a mean of 106% since January 2020.
Most analysts now anticipate that demand for inexperienced hydrogen – which is produced by way of the electrolysis of water utilizing renewable electrical energy – will soar within the coming years. Electrolyser installations are projected to develop by greater than an element of two,000 from 0.5GW immediately to greater than 1,000GW by 2050, in response to information shared by S&P International Commodity Insights with Vitality Monitor.
The main electrolysis applied sciences presently into consideration are proton alternate membrane (PEM) electrolysis – which works in smaller services, with a variable present – in addition to alkaline electrolysis, which requires rather more area and is a mature expertise used for the reason that Nineteen Twenties. Each applied sciences have vital mineral necessities, with PEM counting on platinum group metals like iridium and palladium, whereas alkaline electrolysers want a considerable quantity of nickel.
Information from the USGS and IMF reveals that the costs of those minerals have been much less affected than minerals required for different applied sciences. Certainly, a latest evaluation means that there are “few dangers to the approaching high-growth section” within the sector.
The excessive value of pure gasoline signifies that inexperienced hydrogen has been trending cheaper than blue hydrogen – which is produced from gasoline together with carbon seize and storage – in sure areas with excessive renewable power potential, such because the Center East.
Electrical automobiles (EVs) sometimes require minerals together with copper and neodymium (a uncommon earth metallic) of their engines, and lithium, nickel, cobalt and manganese of their batteries. The costs of crucial minerals required in EVs have elevated by a mean of 86% since January 2020, with the value of lithium particularly hovering by greater than 400% by the beginning of 2022, and remaining round 200% above its pre-pandemic stage.
Alastair Bedwell, director at automotive intelligence supplier LMC Automotive, which is owned by Vitality Monitor’s mother or father firm, GlobalData, factors out that producers “aren’t typically paying spot value, so they’re considerably insulated”.
“Nonetheless, there isn’t any doubt that had been lithium costs to fall again to the 2021 stage, then the BEV [battery electric vehicle] market would develop quicker than we undertaking,” provides Bedwell. “The battery as a share of a typical BEV manufacturing prices is greater than that for the powertrain share of the price of an ICE [internal combustion engine] car (circa 45% versus 35%), magnifying the affect of excessive battery uncooked materials costs on car value.”
Overcoming bottlenecks
Whereas hovering mineral costs signify tight provide, it will be significant to not view this as suggesting that the world is not going to have sufficient minerals for the power transition. Analysts are clear that the Earth’s crust incorporates enough minerals, and traditionally as world demand has elevated, so have recognized reserves, as firms start prospecting extra. For instance, the USGS stated in 1930 there have been round 80 million tonnes of copper in recognized reserves, however by 1980, this had grown to 350 million tonnes, and by 2020, the determine was at 870 million tonnes.
The problem that the world has witnessed is the results of the problem to make sure that provide can sustain with demand. Whereas demand can shoot up or down, opening mines is an costly, time-intensive course of. It takes 16.5 years on common to maneuver lithium mining tasks from discovery to first manufacturing, estimates the IEA.
Bottlenecks could cause vital short-term disruption, however they need to nonetheless not detract from the advantages of investing in low-carbon applied sciences long-term. “There might be bottlenecks, as with all quickly rising sources of demand,” says Kingsmill Bond. “[But] costs will go up. And provide might be constructed. And the bottleneck might be solved.”
Newer market indicators counsel that markets are transferring on from the post-Covid bottleneck, whereas coverage packages being proposed by governments counsel that international locations are working to hedge towards future bottlenecks.
Copper costs have “dropped again significantly, weighed down by the gloomy financial scenario, warfare in Ukraine and rising rates of interest”, says David Kurtz, director of mining and development at GlobalData. He provides that lithium costs are anticipated to proceed declining now that subsidies on EVs are ending in China.
