Platinum vs. Palladium: Automotive Catalyst Trends and Investment Opportunities

The automotive industry is undergoing a massive transformation, driven by stricter emission standards and the rise of electric vehicles (EVs). This shift has significant implications for the demand and investment opportunities surrounding platinum group metals (PGMs), particularly platinum and palladium. Understanding these dynamics is crucial for investors looking to capitalize on the evolving landscape of automotive catalysts.

The Role of Platinum and Palladium in Automotive Catalysts

For decades, platinum and palladium have been essential components in catalytic converters, devices that reduce harmful emissions from internal combustion engine (ICE) vehicles. These metals act as catalysts, facilitating chemical reactions that convert toxic gases like carbon monoxide, nitrogen oxides, and hydrocarbons into less harmful substances such as carbon dioxide, nitrogen, and water vapor.

Palladium: Primarily used in gasoline engines due to its effectiveness in oxidizing hydrocarbons and carbon monoxide at higher temperatures.
Platinum: Traditionally favored in diesel engines for its resistance to sulfur poisoning and its ability to oxidize carbon monoxide and hydrocarbons in oxygen-rich conditions. Platinum is also seeing increased use in gasoline autocatalysts as a substitute for palladium.

The automotive sector accounts for a significant portion of the global demand for both metals. Palladium sees over 80% of its demand coming from the automotive industry. Platinum sees between 29% and 42% of its demand coming from the automotive industry.

The Impact of Emission Regulations

Stringent emission regulations worldwide, such as China’s VIb standards and Euro 7, are driving increased demand for PGMs in automotive catalysts. These regulations require automakers to reduce vehicle emissions further, leading to higher PGM loadings per vehicle. To achieve lower emissions, a higher volume of PGM content is needed.

Platinum/Palladium Substitution: A Key Trend

The price dynamics between platinum and palladium have led to a significant trend of substitution in catalytic converters. Palladium prices surged from 2018 onwards due to strong demand, supply constraints (particularly from Russia), and tightening emission standards. This made platinum a more cost-effective alternative, prompting automakers to substitute palladium with platinum in gasoline engine catalytic converters.

In 2022, 360,000 ounces of palladium were replaced with platinum, an 80% increase over the prior year.
This trend continued in 2023, with the figure growing to approximately 540,000 ounces, a further 50% increase.

This substitution trend has boosted platinum demand in the automotive sector, with automotive demand for platinum expected to reach 3,283,000 ounces in 2023, up 13% on 2022, the highest level since 2017.

The Rise of Electric Vehicles and Hybrid Vehicles

The increasing adoption of EVs poses a challenge to the long-term demand for PGMs, as EVs do not require catalytic converters. However, the transition to EVs is gradual, and ICE vehicles, including hybrid vehicles, will remain a significant part of the drivetrain mix for the foreseeable future.

Hybrid vehicles, which combine an internal combustion engine with an electric motor, require higher platinum loadings to maintain optimal catalytic converter performance due to the frequent switching on and off of the engine. This is helping to sustain platinum demand even with the growth of EVs.

Investment Opportunities and Considerations

The platinum/palladium substitution trend and the evolving automotive landscape present both opportunities and risks for investors.

Platinum: Platinum’s fundamentals, including high recycling rates, diversified supply, and improving prices, make it an attractive medium- to long-term investment. Platinum is also finding new demand drivers in fuel cell electric vehicles (FCEVs) and the hydrogen economy.
Palladium: Palladium faces challenges from concentrated supply, lower recycling rates, and declining demand due to BEVs. However, palladium’s scarcity and continued use in hybrid vehicles may provide some support for its price.

Investors should consider the following factors when evaluating platinum and palladium investments:

Automotive industry trends: Monitor the growth of EVs and hybrid vehicles, as well as changes in emission regulations and catalyst technology.
Supply dynamics: Pay attention to the production levels in major PGM-producing countries like Russia and South Africa, as well as recycling rates.
Price volatility: Be aware that both platinum and palladium prices can be volatile due to market demand, geopolitical tensions, and supply disruptions.

The Role of Recycling

Recycling of PGMs from spent automotive catalysts is becoming increasingly important. As primary supply declines and demand for PGMs remains strong, recycling offers a sustainable and cost-effective source of these valuable metals.

Automotive recycling makes up a significant portion of total PGM recycling supply.
Recycling rates are influenced by PGM prices, with higher prices incentivizing recycling efforts.

Platinum and the Hydrogen Economy

Platinum is emerging as a key component in the development of the hydrogen economy. Platinum catalysts are used in proton exchange membrane (PEM) electrolyzers to produce green hydrogen from renewable energy. Green hydrogen can be used in various applications, including power generation, heating, fertilizer production, steel making, and sustainable aviation fuel, as well as powering FCEVs.

As the hydrogen economy grows, platinum demand from this sector is expected to increase, further supporting its long-term investment potential.

Navigating the Automotive Catalyst Market

The automotive catalyst market is expected to reach 117.09 thousand ounces in 2025 and grow to 142.18 thousand ounces by 2030, at a CAGR of 3.96%. This growth is driven by the continued reliance on advanced aftertreatment technologies in hybrid powertrains, commercial diesel fleets, and range-extender electric vehicles.

Companies operating in this market, such as BASF SE, Johnson Matthey, and Umicore, are focused on developing innovative catalyst technologies that reduce precious metal content and improve cost economics for automakers.

Conclusion

The automotive catalyst market is undergoing a dynamic shift, with platinum and palladium playing crucial roles in emission control and the transition to cleaner transportation. While the rise of EVs poses a long-term challenge, platinum’s substitution for palladium, its growing use in hybrid vehicles and FCEVs, and the increasing importance of recycling create compelling investment opportunities. By understanding the trends and dynamics discussed in this blog, investors can make informed decisions and capitalize on the evolving landscape of platinum and palladium.
