Gateway Metal

While lithium remains the poster child of the green energy transition, stakeholders and media have started to pay closer attention to the other four “battery criticals” graphite, cobalt, nickel and manganese (for more ARPN coverage click on the respective metal) — and rightfully so.

However, one of the key components of 21^st century renewable energy technology, copper, often continues to fly under the radar — possibly because many of us take it for granted as a mainstay metal, and because the U.S. Government does not consider copper a Critical Mineral.

Followers of ARPN well know that copper is an irreplaceable component for EVs wind turbines, solar panels, the electric grid and other green applications. Its Gateway Metal status (see ARPNs gateway metal report here) coupled with the material needs in the renewables sector have led to projections that ““[t]he world will need the same amount of copper over the next 25 years that it has produced in the past 500 years if it is to meet global demand.”

A recent Wall Street Journal “News Explainer” video clip, accessible here, explores why copper is crucial to the global economy, and how its availability — or, more precisely, looming supply shortage — threatens the green tech transition.

Meanwhile, in spite of numerous pushes for copper’s addition to the United States government’s Critical Minerals List  – including ARPN’s Daniel McGroarty’s Public Comment responding to the Department of Interior’s draft Critical Mineral List — the United States Geological Survey (USGS) has thus far opted against affording the material “critical mineral” status.

Following the most recent USGS rejection, House Republicans from Western mining states set out to achieve “critical mineral” designation for copper via legislation.  As the WSJ explainer makes clear, the coming supply crunch puts an exclamation point on the case for copper as “critical.”

Amidst the global push towards carbon neutrality, “Critical Minerals” has become a buzzword.  As the green energy transition has gone mainstream and electric vehicles and renewable energy sources dominate the news cycle, so has talk about growing demand for some of the specialized materials underpinning this shift — most notably the Rare Earths, and the battery tech metals Lithium, Cobalt, Graphite and Nickel.   A little lost in the media shuffle, though no less important, is Copper — perhaps the unsung hero of the green energy transition.

Less flashy and headline-grabbing than some of its tech metal peers, this mainstay mineral deserves far more credit and attention than it is currently getting.  Followers of ARPN will know that we have long touted the versatility, stemming from its traditional uses, new applications and Gateway Metal status.

Copper is also an irreplaceable component for advanced energy technology, ranging from EVs over wind turbines and solar panels to the electric grid.   The manufacturing process for EVs requires four times more Copper than gas powered vehicles, and the expansion of electricity networks will lead to more than doubled Copper demand for grid lines, according to the IEA.

A recent graphic by Visual Capitalist depicts the Copper intensity of the energy transition with a view towards solar and onshore and offshore wind energy technology:

Add in Copper’s Gateway Metal status — the processing of the metal yields access to a host of co-products essential to “manufacturing the advanced technologies that will power our economy for generations to come”  such as Cobalt, Tellurium, Molybdenum, Rhenium, Arsenic and REEs  — and a 2019 mining executive’s projection that “[t]he world will need the same amount of copper over the next 25 years that it has produced in the past 500 years if it is to meet global demand.

Recent developments in Washington, D.C. — movement on a bipartisan infrastructure package and announcements of new EV goals and fuel efficiency standards — will only add to the outlined Copper demand scenarios.

And the challenge is not just mining, but also processing, as Laura Skaer, a member of the board of directors of the Women’s Mining Coalition and former director of the American Exploration & Mining Association, outlined in a recent piece for Morning Consult:

“Last year, the United States imported 37 percent of the copper we used. China already refines 50 percent of the world’s copper and the United States only refines about 3 percent. National security experts have warned that relying on China for critical supply-chain materials like refined copper poses a serious threat to America’s national security interests.”

The United States Government failed in 2018 to include Copper in its official Critical Minerals list, a faux pas the Canadian government did not commit with the release of its own Critical Minerals list earlier this year, which included Copper along with fellow key Gateway Metals Nickel and Zinc in its list of 31.

Meanwhile, the Biden Administration’s 100-Day Supply Chain Review highlights Copper as an integral component of Lithium-ion battery technology, in the context of being what we have called a “gateway metal” to other critical materials, and for its “use across many end-use applications aside from lithium-ion cells, including building construction, electrical and electronic products, transportation equipment, consumer and general products, and industrial machinery and equipment.” 

Here’s hoping that the greater prominence given to Copper — both as a standalone material and Gateway Metal — by the White House 100-day report is an indication that a forthcoming updated U.S. Critical Minerals List will acknowledge the metal’s ever-growing importance.  Until then, Copper will remain one of the most “Critical Non-Criticals,” as we note in ARPN’s recent report, Critical Mass.

While we’re still waiting for policy makers and other stakeholders to take further action, in 2018 an important step was taken to set the stage for mineral resource policy reform with the release of the Department of Interior’s List of 35 Minerals Deemed Critical to U.S. National Security and the Economy. Throughout the drafting stage [...]

“Identifying which minerals are ‘critical’ is the easy part. Working out what to do about them is going to be much harder.”  – That’s the conclusion Reuters columnist Andy Home draws in his recent piece on the current Administration’s efforts to develop a strategy to reduce import reliance for metals considered “critical to the economic and [...]

While just a few short years ago, Rare Earth Element coverage dominated non-fuel mineral resource news cycles, it is the metals and minerals that fuel electric vehicle and battery technology that are making headlines these days. Here, the spotlight has been on Cobalt, Lithium, and, to a lesser extent, Nickel and associated supply and demand [...]

As part of our latest feature series “Materials Science Profiles of Progress,” in the context of which we highlight positive steps towards the development of the comprehensive mineral resource strategy our country is so sorely lacking, we’re zeroing in on a promising public private partnership that recently celebrated its first birthday. In October of last [...]

Another week, another great infographic by Visual Capitalist – this time on the “Secret Driver of the Battery Revolution” – Nickel. Long an important base metal because of its alloying capabilities, Nickel’s status as a Gateway Metal, yielding access to tech minerals like Cobalt, Palladium, Rhodium and Scandium – all of which are increasingly becoming [...]

We appreciate them for their traditional applications, but metals like Copper and Tin are far more than your mainstay materials.  We discussed their Gateway Metal status here, but it’s not just the fact that their development yields access to some of the most sought-after tech metals that makes them so indispensible – it’s advances in materials [...]

Over the course of the last few weeks, we reviewed Nickel and its co-products Cobalt, Palladium, Rhodium and Scandium as part of our trip “Through the Gateway.” We’ve established that the importance of each of the co-products is growing as the revolution in materials science advances. Meanwhile, our import dependence for each of the co-products is [...]

As we near the conclusion of our journey “Through the Gateway,” we noticed that one metal has kept popping up in our coverage – Scandium. A co-product of Tin, we also discussed it in the context of the alloying properties of Gateway Metal Aluminum. It is also a co-product of Nickel. There is good reason it keeps popping up. For [...]
