Clean Technologies Have More Complicated Mineral Requirements Than Fossil Fuels: A Critical Commitment To Transition Critical Minerals

By Leanne Kemp, Contributor

Critical minerals mining must evolve in line with growing investor appetite for ESG compliance. In any moment, in any circumstance, a junction appears where we must align ourselves with trust, transparency and truth to prevail. Could blockchain-enabled provenance platforms help tell the truthful stories that mining companies, battery manufacturers, investors and governments need?     

Picture this: ten years from now, most people will own something powered by an industrial battery, and many more will benefit from large scale infrastructure powered by these batteries. Anything and everything including electric vehicles, electronics, wind turbines, charging stations, solar panels, and transmission lines will rely on industrial batteries as their power source.

The clean energy revolution is upon us and just as previous industrial leaps have been built on steam power and oil, this coming one will be powered by technology we still consider emergent.

Before you pat your future self on the back, take a moment to learn from history and take a closer look at the not-so-humble-anymore battery. While the output of an electric vehicle is greener than a diesel-powered van, consider the core components of the battery itself and you may start seeing a complete picture that is less verdant green and verging more towards rusty mineral orange.

The race is on to supply the critical minerals and metals that are the essential building blocks for the clean energy technologies of the future. The reality is that industrial batteries can’t be built without copper, lithium, nickel or cobalt alongside other rare earths.

Europe leads the world in adopting electric vehicles but lags in being able to access critical minerals locally. So how do we ensure that electric vehicles or clean energy storage is a green as it can be?

By 1 January 2026, each industrial battery and electric vehicle battery placed on the market in Europe or put into service shall have a “battery passport”. This means that industrial batteries and electric-vehicle batteries whose capacity is higher than 2 kWh will have an electronic record, which “should be unique for each battery and to be identified through a unique identifier”, according to the regulation guidelines.

The opportunity is clear but not without challenges. In the transition to clean energy, mining companies and jurisdictions can lead the revolution as long as rising challenges around environmental, social and governmental (ESG) compliance keep pace. Consumer demand, government regulation and, perhaps most telling, investor pressure, have focused the attention on green credentials, just look at the largest investors such as Blackrock BLK , with more than US$10 trillion under management (yes trillion), screening out poor ESG credentials. Now is the time ESG becomes a necessity for industry, business, shareholders and governments to listen up.

All considerations, from now on, must be seen through a climate lens, especially as investors buy into the journey to net zero. There is no capital shortage – it’s the supply of bankable projects that is lacking. Climate risk is investment risk, and the narrowing window for governments to reach net-zero goals means that investors need to start adapting their portfolios.

And what’s more, it’s a global issue. Australia is one of the leading exporters of critical minerals and rare earths, but so far has low usage of industrial battery technology, and now is the time to rectify mining practices so the supply of batteries in Europe, starts in a green genesis on the other side of the world.

“The call for zero net emissions by 2050 is a major wake-up call for the mining industry,” explained Jeff Haworth, Director of the Geological Survey for the government of Western Australia, an important territory for critical metals, minerals and rare earths in energy, automotive, aeronautic and defense markets. “How do we actually become negative in carbon emissions, and yet still supply the world's needs for critical minerals? It’s a daunting proposition. Clean energy technologies will quadruple by 2040. Demand for batteries will accelerate nine to 10-fold over the next decade. All countries and car companies have ambitions around batteries and EVs, so we need to mine those resources responsibly. We can't rely on carbon offsets.” 

Price and provenance

Over the last five years, Jeff has seen ESG become more and more important in discussions with investors. “Jurisdictions such as the European Union are driving that change with its Battery Passport and the strengthening of certification by CERA (Certification of Raw Materials) and IRMA (Initiative for Responsible Mining Assurance). Suppliers increasingly need to prove that they are mining with environmental responsibility, fair labor costs and conditions, as well as benefits to impacted communities. The major car OEMs are coming on board with that as well, demanding evidence of ethical and green mining. It used to be all about price, not provenance. Now, buyers are increasingly willing to pay a premium price, knowing that a mineral or metal is ethically mined, sourced, or recycled.”

Tony Knight is Chief Geologist for the state of Queensland, also in Australia, helping the industry become more efficient and effective in exploration, discovery and development of new mineral supply chains or supply in general. “There’s no doubt we’re going to see a substantial change in the way we find and process minerals to minimize our carbon and water footprint,” he said. “This wholescale modernization will require a change to the economics-first approach, whereby profit is the key and only driver. We have a global problem that resources are running out, even as the population is rising dramatically. Demands will grow, while the planet cannot. That means a shift to minimize what we take, and to maximize what we can put back.”

Within the next decade, Tony believes that the provenance of a mineral will become as fundamental as its quality. “Purity of ore can’t just entail chemical composition. It needs to describe whether it was sourced from an unethical part of the world or at huge expense to the environment. That provenance story is becoming mainstream for products such as food and also clothing. The mineral sector needs to be part of the societal transition.”

Show not tell

Simply saying you’re doing the right thing is no longer sufficient with investors or regulators. Likewise, the media and consumers are developing an acute sense for greenwashing. This ability to prove ESG credentials beyond doubt is part of the challenge faced by mining companies. “For a long time, we focused on ‘what we supply’,” said Tony. “The ‘how we supply it’ piece is incredibly important these days. That's what will differentiate suppliers into the future. We’re seeing greater urgency to trace where a product came from and then track its journey into second life within the circular economy. This will eventually become business as usual, but the early-moving jurisdictions, industries or sectors will stand to benefit from short-term price differential.” 

Jeff agrees that more needs done to broadcast a truthful story that connects back to underlying data and proof. “In Western Australia, we’re stepping away from diesel towards natural gas and also renewable energy to reduce greenhouse gases, and there’s a growth in haulage trucks powered by hydrogen or ammonia to further reduce that footprint. Markets are looking at electrification of the railway lines from mine to the ports, as well as autonomous mining to reduce the impact on personal safety and performance, while further cutting emissions. We also have a lot of good stories about how the mining industry contributes to local Aboriginal and rural communities. So, we have those ESG credentials, we just don't talk about them as well as we could.”

Jeff welcomed the launch of a blockchain pilot programme by the Commonwealth Government that aims to create a ‘digital certification’ for critical minerals throughout the supply chain from extraction to processing and export to global markets. The pilot will help companies in the sector adhere to compliance regulations and increase the demand for Australian minerals in global markets, while also simplifying the process and lowering costs.

(For those wanting to go deeper on the tech think of it as Layer-1 and Layer-2 scaling solutions are two sides of the same crypto coin: they’re strategies designed to make blockchain networks faster and more accommodating to a rapidly growing user base. These strategies are not mutually exclusive either, and many blockchain networks are exploring combinations of Layer-1 and Layer-2 scaling solutions to achieve increased scalability without sacrificing adequate security or decentralization.)

“This will prove helpful for us as regulators, but also help the mining companies, purchasers and OEMs that need to know where metals and minerals have come from. Western Australia is an important global supplier of both lithium and nickel, and we are looking at fingerprinting of both these critical minerals, learning from the recent progress by the gold mining industry. It’s important for governments to help companies navigate their way through these ESG and emissions requirements, because they can be quite complicated, especially for small and medium-sized companies.” 

Creating new markets

The pilot shows the abundant opportunities for tech companies and entrepreneurs to accelerate the green transition, in mining and other sectors. For example, provenance technology can help strengthen domestic mineral supply chains, reduce the reliance on foreign minerals, and minimize carbon emissions, helping local industries rise to the top of an ethical, sustainable supply chain.

The flood in investment in green technologies opens the door to innovation, such as the development of substitutes for rare materials that are more plentiful, sustainably sourced or more easily recycled, recovered and reused. “We’ll see technologies introduced to make manufactured goods easier to recycle and new industries arise from the opportunity to recycle minerals. It feels inevitable that governments will demand better use of minerals, moving from a linear to circular economy,” said Tony.

However, we’re not there yet. While green technologies such as urban mining and circular economy are beginning to be better understood by industry, we’re still in the education phase. “The mineral sector will take time to let go of the economic imperative, which obviously can't be abandoned entirely,” conceded Tony. “We have to recognise that payback periods can't be as short as they used to be. We need more patient capital to get these cycles running properly.” 

From my own perspective it’s also encouraging to see that marketplaces such as the London Metals Exchange begin to list “green” metals in a positive, experiential way with where associated carbon footprints attract a premium.

Nature positive 

One of the big discussions at COP26 was around carbon tax. Some countries are introducing it, or have already introduced it, and others are sitting on the fence. We are at a crossroads. Do we accept that the price the planet is paying is simply a cost externality that’s simply too expensive to deal with? Or could provenance technology play a role in helping to establish where taxes should be introduced, and identifying where companies are doing the right for rebate or showing best practice?

I was also interested to hear the growing buzz in Glasgow around climate financial disclosures and how they are edging closer to government policy. In recent years, we have seen a fundamental shift in responsibility through, first, the climate-related financial disclosures and now the nature-related financial disclosures. The slogan “no carbon negative without being nature positive” was voiced in many conversations. 

“We can’t just see nature as a commodity, but a finite resource,” said Tony. “The question we need to ask is: How can we adopt the economics of nature, giving the natural environment a value that we haven't done in the past? Surely, we can avoid situations where it’s cheaper to pump methane into the environment than it is to manage it. Does that change come from government regulation, market forces or is it voluntary? Either way, there seems an inherent logic in preventing pollution. We need to think of commerce beyond just price. It's got to be price and provenance in the same realm.”

Investors increasingly want to see a better balance between people, planet, profit and prosperity. That will require trade-offs. There needs to be an awakening around the externality of costs to the planet that we ignore. In effect, the environment is subsidizing our economic activities. Eventually, it will run out of patience.
