The Role of Critical Minerals in Clean Energy Transitions

Last month (April 2022) the International Energy Agency made a few corrections to its 2021 report The Role of Critical Minerals in Clean Energy Transitions. There are a couple of versions available online, the full report (250 pages) and a much shorter extract or Executive Summary.

I would like to propose a few points to mull over taken from my understanding of the findings.

From the report:

Solar photovoltaic (PV) plants, wind farms and electric vehicles (EVs) generally require more minerals to build than their fossil fuel-based counterparts. A typical electric car requires six times the mineral inputs of a conventional car and an onshore wind plant requires nine times more mineral resources than a gas-fired plant. Since 2010 the average amount of minerals needed for a new unit of power generation capacity has increased by 50% as the share of renewables in new investment has risen.

Lithium, nickel, cobalt, manganese and graphite are crucial to battery performance, longevity and energy density. Rare earth elements are essential for permanent magnets that are vital for wind turbines and EV motors. Electricity networks need a huge amount of copper and aluminium, with copper being a cornerstone for all electricity-related technologies.

As energy transitions gather pace, clean energy technologies are becoming the fastest-growing segment of demand. In a scenario that meets the Paris Agreement goals (as in the IEA Sustainable Development Scenario [SDS]), their share of total demand rises significantly over the next two decades to over 40% for copper and rare earth elements, 60-70% for nickel and cobalt, and almost 90% for lithium.

The report estimates that the need for these minerals will double between today and 2040, but if we are to reach the goals of the Paris Climate Agreement the increase would be four-fold, and to reach net zero carbon emission six times as much as currently produced would be required.

The growth is not equally distributed across sectors however. If we are looking at storage (batteries) for electric vehicles and the likes:

Lithium sees the fastest growth, with demand growing by over 40 times by 2040, followed by graphite, cobalt and nickel (around 20-25 times). The growth of hydrogen as an energy carrier brings different mineral uses and growth in demand for nickel and zirconium for electrolysers, and for platinum-group metals for fuel cells. 

Existing mines and projects under construction is estimated to meet only half of projected lithium and cobalt requirements and 80% of copper needs by 2030, and it takes on average 16.5 years to take the first minerals out of the ground after discovery, so the clock is well and truly ticking.

As regular readers will know, I am interested in the geopolitical implications of technological development, so here are a few more nougats for thought:

For lithium, cobalt and rare earth elements, the world’s top three producing nations control well over three-quarters of global output. In some cases, a single country is responsible for around half of worldwide production. The Democratic Republic of the Congo (DRC) and People’s Republic of China (China) were responsible for some 70% and 60% of global production of cobalt and rare earth elements respectively in 2019.

The level of concentration is even higher for processing operations, where China has a strong presence across the board. China’s share of refining is around 35% for nickel, 50-70% for lithium and cobalt, and nearly 90% for rare earth elements.

And we have to remember that mining for minerals is not always a pretty affair, and brings lots of social and environmental concerns.

The report makes six recommendation that are summarized in the Executive version as follows:

1. Ensure adequate investment in diversified sources of new supply. Strong signals from policy makers about the speed of energy transitions and the growth trajectories of key clean energy technologies are critical to bring forward timely investment in new supply. Governments can play a major role in creating conditions conducive to diversified investment in the mineral supply chain.

2. Promote technology innovation at all points along the value chain. Stepping up R&D efforts for technology innovation on both the demand and production sides can enable more efficient use of materials, allow material substitution and unlock sizeable new supplies, thereby bringing substantial environmental and security benefits.

3. Scale up recycling. Policies can play a pivotal role in preparing for rapid growth of waste volumes by incentivising recycling for products reaching the end of their operating lives, supporting efficient collection and sorting activities and funding R&D into new recycling technologies.

4. Enhance supply chain resilience and market transparency. Policy makers need to explore a range of measures to improve the resilience of supply chains for different minerals, develop response capabilities to potential supply disruptions and enhance market transparency. Measures can include regular market assessments and stress-tests, as well as strategic stockpiles in some instances.

5. Mainstream higher environmental, social and governance standards. Efforts to incentivise higher environmental and social performance can increase sustainably and responsibly produced volumes and lower the cost of sourcing them. If players with strong environmental and social performance are rewarded in the marketplace, it can lead to greater diversification among supply.

6. Strengthen international collaboration between producers and consumers. An overarching international framework for dialogue and policy co-ordination among producers and consumers can play a vital role, an area where the IEA’s energy security framework could usefully be leveraged. Such an initiative could include actions to (i) provide reliable and transparent data; (ii) conduct regular assessments of potential vulnerabilities across supply chains and potential collective responses; (iii) promote knowledge transfer and capacity building to spread sustainable and responsible development practices; and (iv) strengthen environmental and social performance standards to ensure a level playing field.

All of which would fit within a Responsible Innovation approach.

Take a look at the executive summary linked above (the full report is also available there). All of this information is presented in graph form and very easy to digest.

Why Tesla will be the biggest company of this decade

This is going to sound nuts, but I believe the most important company of this decade will be a “car” company. Specifically Tesla.

But why?

Here are my thoughts.

Tesla’s Mission

“Tesla’s mission is to accelerate the world’s transition to sustainable energy.”

That’s a direct quote from Tesla’s website. It’s what their founder, CEO and Technoking (yes, that really is his title! 😂) Elon Musk believes, so much so, that Tesla’s patents are open-source – the goal being so others can benefit from the advancements Tesla have made.

Elon believes that even with access to Tesla’s intellectual property, competitors still won’t be able to compete, thanks to the companies software and manufacturing excellence.

The first step to becoming a great organisation is having a mission people truly care about and believe in. In my book, there aren’t many missions stronger than trying to make the world a better place to live.

Tesla’s diverse business(es)

It’s a great misconception to believe that Tesla is a “car company”.

  • It’s a sustainable energy company, selling solar panels and solar tile roofs ☀️
  • It’s an energy storage firm, selling Powerwalls and Megapacks to individuals, businesses and countries! 🔋
  • It’s a utilities provider, powering homes and businesses
  • It’s a battery pack and cell manufacturer, working on it’s 4680 cell technology for the cars of the future 🔋
  • It is also a car company, building, assembling and selling the fastest, most efficient electric cars on Earth! 🌍
  • It’s a vehicle manufacturer, developing a pick-up (Cybertruck) a lorry (Semi) and an ATV (Cyberquad) 🛻🚛🏍️
  • It’s in the servicing industry, providing the parts and labour required to maintain all Tesla products 🛠️
  • It’s a rapid-charging network, with more than 25,000 Supercharging stalls globally ⚡
  • It’s an insurance provider, providing cover for those driving it’s cars 📄
  • It’s a software company, designing it’s own mobile apps and the in-car interface ⚙️
  • It’s an AI robotics firm, developing the code for Full Self-Driving (Level 5 Autonomy) and the Tesla Robot 🤖
  • It’s a supercomputer manufacturer, building the most powerful computer of all time, to support it’s AI 🖥️
  • It’s a currency trader, holding Bitcoin and selling in multiple currencies around the world 💱

All-in-all, Tesla has a huge number of areas of speciality, and is vertically integrated to the extreme!

Tesla aims for the moon, in EVERYTHING it does

Tesla has a culture of being the absolute best in class at everything they do. Tesla doesn’t settle for second best, if they commit to something, they’re aiming to be the best.

They didn’t just aim to make a fast electric car, they aimed to make the fastest production car in the world – and they did!

They wanted to build safe cars, and they really did – when released, the Model 3 was the safest car the NHTSA had ever tested! The Model Y received top marks too.

NHTSA Tesla saftey

They aren’t satisfied with a Gigafactory, they’re aiming to be able to produce 10 terawatt-hours of battery capacity by 2030. VW is a leader in electrification among the legacy automakers, “boldly” aiming for 240 gigawatt-hours of capacity by 2030. Tesla is aiming to produce that (and another 10gWh) from their new Berlin factory alone… in the next few years!

They aren’t aiming for gold standard driver assistance aids, they’re working on fully autonomous vehicles, which are already 10 times safer driving than a person. Entertainment centres on wheels, with Netflix built-in, and no need for steering wheels.

They aren’t even satisfied with the cars as they are when they sell them, so they’re constantly tweaking, enhancing and upgrading them with free, over-the-air software updates. Extras include: entertainment upgrades like the YouTube app and Fallout Shelter game; Sentry mode, a security camera recording system; power boosts and range improvements; faster charging speeds; mapping upgrades and charge station updates; and much, much more.

The entire fleet provides data to Tesla and their neural nets are constantly learning and improving features, be that airbag deployment safety, automatic wipers sensitivity or full self-driving accuracy.

They weren’t happy welding individual parts together, and now use a Gigapress/gigastamp, which speeds up production and improves quality – stamping car bodies out like toy cars! This helps them to produce a car every 2 minutes!

They have Elon Musk

Whatever your opinion of the man, he’s a visionary, with extraordinary determination, and the ability to galvanise a cult-like following. He’s had huge success in the past with Zip2 and X.com (which became PayPal), and his current companies are doing pretty well too!

In September, SpaceX sent four regular people into space. They orbited the Earth for 3 days, higher than the ISS and higher than any human has been since we went to the moon. The Starlink satellites are rolling out rapidly, offering high-speed, low latency internet globally.

Having multiple companies which can integrate and share knowledge is a huge bonus. For example, what other car manufacturer is able to send a car into space – like Elon did with Starman in his Tesla Roadster.

His approach to a problem is to make the product ten-times cheaper through relentless efficiency and looking at the problem in a new way. One example can be seen at SpaceX, the view there was that throwing a rocket away after each launch was a big contributing factor to its cost. Elon often likens it to throwing away an aeroplane after each flight, it’s madness! So SpaceX engineered self-landing rockets, a phenomenal idea, cost saver and huge achievement!

Musk also owns The Boring Company, which is creating tunnels under major cities to enable significantly faster transportation – another service Tesla cars could benefit from.

The knowledge sharing across his companies is a huge advantage, Tesla’s competitors just don’t have.

Footnote

I’ve been meaning to write this post for a few months now, and started working on it in September. This was before Tesla’s huge Q3 deliveries and financial results, and the massive stock growth which followed – making them the 6th biggest company (by market capitalisation) in the world! It seems like these developments further support the thinking that Tesla will be the biggest company in the world this decade.

EV Charging 101

Following Jonny’s electric vehicle charging article, here’s everything you need to know about charging an EV in Europe – from someone who’s driven one since 2019!

You’ve Bought Your First EV 🔌🔋⚡🚗

Fiat 500e Convertable
The convertible Fiat 500e

First of all, fantastic work, you’re awesome!

Thanks for making a great decision and welcome to the future!

So charging, that’s something you need to do now… no more dinosaur juice for you, you’re EV all the way!

🛢️🦕⛽💥

☀️💨🔋⚡

But how do you charge?

Types of Charging

Charging is really a lot simpler than you’d think, there are just two types:

  1. AC – Slow and Fast charging
  2. DC – Rapid charging

AC Charging

Slow Chargers

A slow charger uses AC power. Alternating current (AC) is what comes out of your plug socket at home.

In fact, plugging your car into a Schuko/3-pin plug, is an example of slow charging.

The charging lead (often called a granny charger, because of how slowly it charges) plugs into your home socket at one end and your car at the other. Some chargers and cars enable you to select how many amps to pull. A Tesla can pull between 5 amps and 10 amps from a domestic socket. You might want to vary the amperage if your house has poor electrics, or if you’re trying to use what your solar is generating.

So how much charge can a home plug socket provide?

10 amps x 230 volts = 2.3 kW (kilowatt)

The Tesla Model 3 Standard Range Plus has a 50 kWh battery pack, so on a 3-pin plug in the UK, you can charge half the battery (or 25 kWh) in 11 hours. That’s over 100 miles topped up on cheap, renewable electricity while you sleep.

Fast Chargers

Fast charging also uses AC power. If you get an EV chargepoint installed at home, it is likely to be a 7.4kW fast charger.

This would enable you to completely “fill” a Model 3 from empty to full in a little under 7 hours.

Fast charging speeds are limited by the cars onboard charger. This converts the AC power into DC power, to feed into the car’s battery.

Charging by AC and DC

Some BEVs (battery electric vehicles) have powerful onboard chargers, like the Renault Zoe, which can charge at up to 22kWh. The Model 3 has a 11kW onboard charger. Some cars are limited to slower speeds, like the VW e-Up! limited to 7.2kW AC charging.

Many supermarkets and retail parks have fast chargers onsite – which are often free! Spending 60 minutes in the supermarket can give you ~40 miles of charge.

DC Charging

Rapid and Ultra-Rapid Chargers

Rapid (and Ultra-Rapid) charging uses DC power. This means the power can be fed straight into the battery.

Rapid chargers can charge from speeds of 43kWh, to speeds upwards of 350kWh!

If you’re on a long road trip, you’d use a rapid charger to top-up the battery at super speed!

The Tesla Supercharger network is an example of an ultra-rapid charging network. Many Supercharger stalls now have 250kW chargers! A Long Range Model 3 can charge at up to 250kWh, which is over 1,000 miles an hour!

Using the Supercharger network, you can top-up 200 miles of range in 15 minutes. That’s 3 hours of motorway driving in the time it takes you to visit the toilet and get a cupa tea.

Rapid chargers tend to be more expensive than Slow and Fast chargers, but they can deliver power at much faster speeds.

Rapid chargers are sometimes supported by battery storage, to ensure consistent supply and the cleanest possible energy. Here’s a video of the GridServe charging hub from the awesome team at Fully Charged.

Charging Plugs

European charging connectors are also really simple now.

European AC connectors for Slow and Fast charging are:

  1. Type 2 (AKA mennekes)
  2. Type 1

European DC connectors for Rapid charging are:

  1. CCS (AKA Combo 2)
  2. CHAdeMO

CCS and Type 2 use the same plug design – CCS is basically a Type 2 plug with an extra two pins.

A CCS plug (left) and a Type 2 plug (right)

Both have been the standard socket in Europe for some time now, with CHAdeMO and Type 1 slowly being phased out.

Some charging posts have more than one type of connector – using the right one for your car will ensure you get the best speed! For example, using a Type 2 charging lead will charge much slower than a CCS lead – if your car has both sockets.

Many charging units can charge more than one car at a time, but not all, so it’s worth checking beforehand.

Generally speaking, Slow and Fast chargers (away from home) don’t come with a charging cable – you plug your own in. Rapid chargers however always come with a cable – be that CCS or CHAdeMO.

Finding a Charger

The UK has more charging stations than petrol stations, so it’s not difficult to find a charger. To help you out (in the UK) Zap-Map have a fantastic live, interactive map! PlugShare is a similar map, which covers most of the world!

How many chargers are there within 10 miles of your home?

I bet it’s more than you thought!
