  • Are critical minerals the Achilles heel of the energy transition?
    Climate change deniers will tell you that a zero emissions economy is a pipe dream. They say there's not enough lithium for all the batteries we'll need, that mining rare earths is destroying the environment and that we can’t get cobalt without sending children down mines. So, is the energy transition doomed before it even begins?
    In this video, we're going to explore the challenges and opportunities associated with these minerals, and we'll ask the tough questions that will need answers if we’re going to pull off the energy transition.

    The difference in strategic risk between minerals and fossil fuels is that if prices spike you don't need to buy.
    OPEC controls the world oil price and can send inflationary shockwaves around the world, and yet here we are saying "better be cautious about China processing those minerals".

    Another excellent video Rosie.
    A couple of points came to mind, it never hurts to point out that a significant user of Cobalt is in production of Diesel, which is more than a tad ironic.
    You could add to the list of things Tesla is doing as they are building a Lithium refinery in Texas to further onshore. Sandy Munroe said in a video he did that he had been hired by Valle to improve the air filtration at a mine because although the standard was sufficient for the government, Tesla insisted on higher standard from it's suppliers.

The IEA say 30% 'EVs+storage', 70% everything else, in 2020. Benchmark say batteries went from 38% of lithium demand to 85% between 2016 and 2023 so things are changing fast and checking the date on any stats is important. They also say total production will grow 30% by 2026 and 90% of that will end up in batteries. So all the 'other' uses (steels, ceramics, catalysts, medical) will become increasingly de minimus.

    Very good, even handed and accurate presentation. One thing worth mentioning: the real concern about lanthanides (the real "rare earths") is their MILITARY applications, not their cleantech applications which all have substitutes. Furthermore, getting rid of fossil mining (or at least reducing petroleum mining greatly, eliminating coal mining and nearly eliminating gas mining) will dramatically reduce how much actual mining goes on here on earth. The transition not only allows substitution that the fossil fuel paradigm fundamentally was incapable of, but also will result in less mining and a near elimination of resource destruction- all the cleantech applications of "critical minerals" allow recycling- they don't dump the product into the atmosphere at end of life.

      I've got one coming up on mining in general and how to make it zero emissions. It's crazy to me that we keep hearing how the energy transition will require six times as much mining... That's true for minerals but conveniently leaves out that HALF of all mining today is for fuels! So far less mining overall and as you point out that's only in the short term. In the longer term there should be very little as recycling takes over from extraction.

      @@zen1647 No, not really.
      We currently have a test machine EV Sandvik Jumbo (face drill). It's been on site for about 4 months now and is only just looking like getting it underground to try.
      The drills normally run on diesel power to move around and 1000v power while drilling. This EV version is not capable of 'traming' very far - one to two levels at most.
      This may work in some mines, but not all of them, as most have their workshop facilities on the surface where logistics and manpower is better and diesel machine can easily travel to.
      For the loaders, Sandvik is also trialling EV versions, but not in the capacity sizes used in Australian mining - move more with one Machine = more profitable enterprise.
      Electric Underground trucks are a long way off for decline mining, due to the travel distances and power required to move the 65t load plus the truck up a 1:7 decline slope for 6 or 7km of roads. The current Volvo power plant is a 567kw. They have a battery variant available, but it is suited to tramming in the levels and dumping underground into ore passes rather than hauling to the surface.
      Both the loader and the truck have a battery exchange function and could be used as short haul units, but they are more costly to purchase and then need banks of batteries on charge for the fleet.
      In addition, we all know the risks of a runaway battery fire, now try to imagine how that would be when you are in the same underground location and breathing the same air with that battery pack and all you have is a respirator mask you need to quickly put on and make your way through the smoke to a refuge chamber...
      In theory, yes the 'fleet' could be electrified, in practice there is a great many hurdles to pass over.

      Doubt it. The Lithium we mine here in Western Australia is processed using good old Collie Coal, although more coal is imported from New South Wales I beleive nowadays. The processing of green minerals in WA is absolutely minimal - just the bare minimum to reduce the weight so that it can be shipped to China and Korea more economically. Whilst I dislike West Australias dutch disease as much as the next Sandgrouper, reality is, we have a labour shortage as it is (apparently anyway), so the idea of putting more skilled labour towards minerals value-adding is a bit of a silly sausage notion. I fully admire your good intentions though, I'd like to see it myself..

      It's technically possible to electrify just about any process, whether it is practical or economical is the thing that most people overlook.
      Open pit mining excavators and face shovels can be plugged into grid power, and surface haul trucks can use a pantograph system if they are following a set route, and maybe have very limited battery capacity to drive 'off course' away from the high voltage power.
      Underground drills run on 1000v power already for drilling operations, but use diesel engines to tram to different locations around the mine (and surface workshops, fuel bays etc)
      There are battery rigs available and our company has some, but we're still carrying out risk assessments for they due to the massive battery packs and the fact that workers share their breathable air with these machines.
      Some U/G trucking and loading operations on single levels could be set up for the latest battery pack 'swap and go' machines, but not for regular mining operations where locations constantly change during a shift and trucks run up a 1:7 incline for 30 mins carrying 65t of dirt.
      All of the above also assumes that the incoming mine power supply is endless.
      Most mines are out in the middle of nowhere and the power supply infrastructure was chosen and supplied based on a known projected future energy requirement.
      (The remaining energy accounted for in diesel)
      To suddenly replace all of the diesel with electrons would in some cases, require changes right back to the initial point of supply.
      I'm no 'fan' of diesel, having shared the U/G air with the machines for years, but there is no simple economical quick fix.

      Fundamentally the U.S. needs fossil fuel and if the U.S. needs it so do all western nations.
      The U.S. declared bankruptcy in 1971. Then the U.S. dollar was saved as a global reserve currency because oil became priced in dollars. If the west ends oil then opec will join the BRICs and sell oil priced in yuan.
      You’re effectively destroying the ability of the U.S. to offshore inflation. If you stop oil you end the ability of endless government growth or endless war and bank bailouts.

You use liquid Nitrogen to supercool, freeze the E-Waste so that it’s super BRITTLE, and feed into a hammer mill or grinder, to break it all down into tiny fragments or particles, which are immediately fed into a giant chamber where a powerful artificial whirlwind is created by jets. The whirlwind will segregate the particles, according to their specific mass densities or weights, into free-floating ‘Saturn Rings’, of separated elements. After these floating particles rings are fully separated, chutes pop up to catch the rings and shunt the particles into separate bins, so that they can be easily recycled. EOJ

      Not dangerously dependent but foolishly going down that road, we can still use fossil fuels for transport (China does use carbon and is the biggest polluter at 29%, US 20%, Australia just over 1%, UK less than 1%) and new nuclear along with renewables when they are cheaper and widely available not when we are going to be dependent on another dictator country, we all known what is going to happen in that regard. The imposition on dates for renewable energy transfer is a false construct and will increase prices to an extent to ensure that the COP (Out) plans will not work. Hosting the COP climate change in Dubai has shown that the carbon producers (Who had the biggest delegations in COP previously) have taken control of that enterprise and the deleting of carbon to be phased out from the charter confirms that (Although carbon will in actual fact be used up until the end of the century anyway it was unrealistic to think that it could be totally replaced). The transition from Carbon to Renewables (Not Green as some of them are green only because they are so toxic!) Should be carried out as like with horse and carts to steam and then petrol by economic factors only, not by political intervention on prices, this is having a backlash as it's unaffordable by the majority. For example my old back boiler packed in (30 years service) and it was replace that with a gas boiler, £2,000 tops, or have solar, battery back up, insulation and an air source heat pump £60,000), so funny enough it was replace the gas boiler, later on I will insulate the outside walls internally (£3,000) and it will never pay me back to go "green" in the remainder of my lifetime!?!

    First, thanks for reminding people of the correct definition of rare earth minerals. I get a little twitchy at times when I hear some less that accurate use of the term.
    I know that for many of these things increased supply, as well as source diversification, is critical. I wonder how much this could be eased by robust recycling practices? Certainly that won't solve the problem, but it could somewhat ease the transition. As with every aspect of human existence, being efficient and mindful with the use of our resources is mandatory for our long term well being.

    One thing that annoys me is that critical minerals often go into stationary battery solutions. Why use Lithium for home and utility batteries? If it has the energy density characteristics to sit there and not be mobile at all, and it's affordable, safe and long lasting, then it's a perfectly good stationary battery chemistry. I sincerely hope sodium ion can fulfill this role without too many other rare minerals. I don't care if my home battery is the size of a garden water tank. Truly. Makes it harder to steal even.
    Stationary batteries are as important for tackling climate change as EV batteries. Especially when you consider that stationary batteries compliment renewable energy and EV charging infrastructure very well.

    As a geologist, the frustration I have watching our raw materials shipped overseas for processing and then use, only to come back as finished products is extreme. Mobs like Lynas tried so hard to both mine and refine RE ore in Australia, and was eventually forced to export and process it in Malaysa. We have huge Li deposits in Western Australia (WA), predominatly as pegmatites, and we are lucky enough to have production of technical and chemical grade lithium products produced. Given WA's vast landmass rich with green energy sources and raw minerals, refining, production and manufacturing of high-end good should be very high on the To Do list for the State and Federal Government's. I'm sure other states have similar opportunities that could be with a bit of political will and spine.

    When we got our ~40 year old electrical panel replaced: we were able to upgrade to 125A service from 100A service because #0 sized Al (rated for up to 135A) was used for the supply, instead of #2 Cu (rated for 100A) (due to a copper shortage in the 70's). New installations are supposed to have 0000 Al cable (rated for up to 205A).

    When the British coal industry was destroyed by the Tories in the 1980s and 1990s by weakening the Miner's Union until cheap coal could be imported in bulk from Eastern Europe, there were many British coalmines with estimated reserves of 300 years... they're still there!

The doomers in my blogosphere are really banging on about running out of minerals etc. I also enjoy the footage of the stuff being extracted as a raw resource and then processed etc. Anyway, question. If we were to 'run out' of copper as they so hysterically assert (forgetting various economic feedback loops and recycling etc) - what about this next claim? Aluminium - which is 8% of the earth's crust and more abundant than even iron ore at 5% - could substitute? I'd love you to chat with some industry insiders and technical people in EV's and what-not about what this would take. That's WITHOUT doping it with graphene and whatever people are working on to make 'superconductive aluminium.' Just bog standard aluminium with 60% of the conductivity. How would we do it? This is the claim. Just use more! "This means you will need a 25% thicker wire for the same results. However, the aluminium in this equivalent wire will cost and weight about half as much as copper. That’s it. Aluminium in power lines? Of course! Also underground! And in transformers and coils, in motors? Yes!"
    He claims over 90% of the roles of copper can be replaced with aluminium. I'd love you to either mythbust this one or confirm it with some electrical engineers - car engineers - wind turbine people - etc! www.shapesbyhydro.com/en/material-properties/how-we-can-substitute-aluminium-for-copper-in-the-green-transition/

  • @paulkonowicz1740
    @paulkonowicz1740 หลายเดือนก่อน +1

    Hi Rosie, probably the biggest issue with the clean/green energy transition is that it is almost completely viewed through a first world lens. What about the citizens of less wealthy countries, I'm sure they would like all the mod cons we have. A prime example are electric vehicles, these are a first world luxury because they are expensive and use large amounts of "critical minerals". I know that many people believe there isn't a critical minerals crunch and that there is a lot of copper on earth and rare earth minerals aren't that rare. However, most of the low hanging fruit regarding high concentration mineral deposits have been exploited and mining lower grade deposits is more expensive. At some point the economics won't make sense and who wants the pollution and environmental issues that will come with a huge increase in exploitation of "critical minerals". To replace all the internal combustion engine (ICE) vehicles in the world with electric vehicles using copper wiring and rare earth magnets would require significantly more copper than is present in ICE vehicles and where will it come from? I know that there are other alternatives to electric motors using copper wiring and rare earth magnets one example is an induction motor with aluminium wiring. However, the resistivity of aluminium is lower than copper and larger wires would be necessary. A benefit is that induction motors could potentially be lighter, but they would be bulkier and would be less powerful per unit volume because the same current densities achieved in copper wiring couldn't be reached before melting the wiring. Another huge issue I haven't heard mentioned or discussed is that electric vehicles are a tremendous waste of valuable minerals. I doubt the majority of car owners use them for more than 3h a day. If we are generous and say 4 h that corresponds to a vehicle being idle for approximately 83% of the time. Those resources would be better used for generating renewable electricity from sources can operate at a rate > 17% of the time. And this is not to mention electric cars usually have 2 or 4 motors compared to a possible electric motor cycle. We should consider producing liquid fuels from renewable sources such as biological waste streams, cellulosic biomass etc and live with the energy penalty. The resources that would go to electric vehicle could be put to more productive uses to offset the liquid fuel energy penalty and wean us off fossil fuel use for other applications. We have to remember that we can't sit in our first world ivory tower and need to consider the aspirations of all. Ideally nuclear fusion with cheap and plentiful electricity would come to the rescue, but as it is said, nuclear fusion is always 10-20 years away.
    Best regards,

    Engineering with Rose Coloured Glasses. The most important "Critical Mineral" is COPPER. There are various estimates of the amount of Copper required to enable the energy transition. Most agree that what's required is about 4 times current production and increasing production to that level very SOON. The reality is that copper mining is is generally mined as low grade/high tonnage operations. Most of these large operations from initial discovery through to first production has a time-span of about 15 years. Proving a deposit is expensive. Getting the project permitted is a lengthy process depending upon the location. The recently shut down Cobra Panama operation was a US$10 Billion development which was processing 80-100MTPa at an average grade of 0.4% Cu. The 15 year timeframe is not negotiable. And that's for each and every large-scale operation.

    Keeping up with the subtitles was a bit of a challenge!
    Excellent content though, as I've seen one fellow going on various media trying to say we don't have enough X to move away from fossil fuels.
    From what I understand, most if not all of these things aren't exactly rare, they are however, economically difficult to extract.
    This is important when we consider that mines for things that are economically abundant often start and stop mining,
    depending on whether a company can make money at the time.
    I think the mining industry may have to undergo a revolution of its own to move us into the future.
    Specifically countries may decide to start looking for more "expensive" local sources to ensure supply chains.
    I really do think that more countries have all of these minerals than we are aware of, they just haven't been looked for seriously before.
    To illustrate my point there was a fairly recent discovery in an old volcano in California of a surprising amount of Lithium.
    My country Canada, and Russia, are VAST. I really don't think that either has been exhaustively searched for many of the minerals we are going to need.
    That needs to change, if we hope to reach our goals.
    There are other large countries, such as Australia, Brazil, China, India, Argentina, Algeria, Democratic Republic of the Congo,
    many of which also have reserves of various minerals we've never really looked for.
    If we really want an idea of what seriously mining these resources might look like, we should look at what mining fossil fuels looks like.
    We've found them in all kinds of places that were never considered 100 years ago, simply because we need them.
    Need even more than profit is a driver of resource extraction.
    I will watch with curiosity about where we will find "economical" deposits of these resources.
    I expect more than a few surprises, which COULD be a huge step up for some poorer countries, IF something is found there and developed properly.
    (I know, that rarely happens.)

    It's not just climate change deniers that are saying that there is access to insufficient mineral resources to satisfy the proposed scale of battery production. Simon Michaux talks about the practicalities of mining the required minerals such as lithium and concludes that it's likely unfeasible. He was commissioned by the IEA to provide the feasibility research, so would hardly be considered a climate change denier.
    There is so much more to mining than looking at the probable and possible reserves. A basic understanding of mining will recognise that it's energy intensive and also takes time. Time that we don't have if we are to meet the deadlines for net zero. Renewable energy such as wind, solar, wave, hydro all take time to produce the energy at their steady rate of production(there is also non producing time). Where is the huge amount of energy to mine the minerals coming from?
    It's like using a chisel to dig holes for tree planting and telling someone that they are anti-tree planting when they sensibly suggest to use a spade instead. There is a climate change problem but the current way we are going to address it is a kin to digging with a chisel.
    Companies like janus electric and the x-bus team are putting resources into user removable EV batteries which will allow users to only take as much battery capacity as needed on each trip.

    When more development happens with phase change technology with solar vacuum tubes implemented as energy capture = this will easily lighten the load on mineral extraction- this works best on back yard situations - high density black sand that is abundant around the world and easy to gather = makes a very good thermal battery

    The problem is not only that it runs out but how much it costs and will cost to remove them, something that is already happening with copper, which since 2000 has tripled its price.
    Also do not forget that if global growth continues to rise steadily it will be exponential. And the calculations change completely

      it's used as a catalyst to de-sulfur various cuts - for instance dropping the parts per million sufur content in gasoline and diesel, but also many others. it is consumed in the process but reclaimed at about a 98% level for re-use, so it's at least a quasi durable use of it for several process generations.

      Yes, and it's recovered by cyclones, electrostatic precipitators, and baghouses and retuned to the hydrotreater. Unlike cobalt in lithium ion batteries which all goes to the landfill because battery recycling is financially and energetically uneconomic.

      It's a catalyst used for purification. The problem is that it's a powder, and because of the difficulty and cost of recovery they throw it away. An ICE vehicle uses a much cobalt in a few years as an older battery does, but it's not recyclable--the battery is.
      Any ICE proponent who mentions cobalt as a problem isn't going to like hearing that fact.

      ​@@thekaxmaxThat's a flat out lie and shows you don't have any idea how oil refineries work. All of the cobalt is recovered by cyclones, electrostatic precipitators, and baghouses to the hydrotreaters. Hydrotreating can use multiple different catalysts and cobalt isn't even the majority one. This is all quite unlike the cobalt in lithium ion barriers which is simply thrown away (because battery recycling is completely financially and energetically uneconomic and isn't commercial).

      @@gregorymalchuk272 The newest Tesla batteries don't use cobalt at all (replaced with nickel), and the LFP batteries BYD use also don't have any. So recycling that's a moot point.
      And the crude oil refining that uses cobalt does recover most but not all. So yes, they are throwing away some cobalt--I never said they threw it all away. The chemical processes are fierce and nasty, and there have been leaks.
      And recycling car batteries for household use is 100% recycling. Keeps them useful until material recycling is a thing.

    Yeah the processing of rare earths only can happen in China because their environmental regulations allow for it. Since rare earths are often found with uranium, I wonder why we don't mine it here in Canada. We have always been one of the biggest suppliers of uranium in the world. Surely the tailings piles at our mines could be processed for neodymium or other rare earths without contaminating another location. I think that China is likely making better use of the rocks that they are mining by processing them in multiple ways to extract multiple kinds of minerals

    Hubbert's peak theory of mineral extraction, led to predictions of oil production, peaking in the 1970's. And the theory is still accurate, so what happened? Technological advancements such as fracking, made it a second order factor in oil production. Which is why long-term predictions about mineral production, tend to be, so inaccurate.
    And are government subsidies. such as the US. IRA sustainable?
    So nice overview on an important subject, (even with the clickbaitish title). But would love to hear this discussed among a diverse set of disciplines, including some fellow economists, in a future post.

    Thorium Energy Alliance tried some years ago to set up a "Thorium Bank" to capture the radioactive waste stream from rare earth mining inside USA, since the reason USA doesn't mine them is because of nuclear regulations, not a lack of supply. It blows my mind it didn't get off the ground considering the supply chain risk they have.
