Investment Potential Across the Green Supply Chain

Bernard Chua, Senior Client Portfolio Manager, American Century Investments, explores how emerging trends and new technology are supporting the energy transition.

Alternative and renewable energy sources, such as wind, solar, hydroelectric, geothermal and biodiesel, are capturing headlines. Indeed, investment in the energy transition has gained steadily over the last decade, as shown in Figure 1.

Investment potential of energy transition supply chains

We have identified many companies offering alternative and renewable energy sources. A deeper dive reveals significant investment potential in the supply chains that support these industries.

EV supply chain Is broad

Anyone who doubts the growing consumer acceptance of the shift to electric vehicles (EVs) should consider the popularity of Ford’s all-electric F-150 Lightning pickup and Mach-E Mustang. Despite sticker prices for the most luxurious models approaching US$100,000, wait times currently stand at about 7.5 months and three to four years, respectively, according to the auto industry website Edmunds.com.

EVs also encompass trains, buses, bikes, trucks and commercial fleets, dampening the demand for fossil fuel-based energy sources.

What’s not so obvious is the variety of sectors and industries that comprise the EV supply chain:

  • Makers of sensors, cameras and lenses that enable autonomous or assisted driving and the chips that support them.
  • Companies working to extend EV battery life while simultaneously lowering battery costs (a significant contributor to EV prices).
  • Firms building and supplying parts and technology to meet the growing need for charging station infrastructure.
  • Metals and mining firms that supply and process the materials needed to build and power EVs. These metals include lithium, cobalt, nickel and copper.

The extraction and processing of these inputs come with sustainability risks. We are monitoring this situation carefully and note that newer technology helps mitigate some risks by providing alternative material choices for EV battery manufacturing.

Automation and green architecture supply chains

The EV supply chain isn’t the only supply chain to consider. Factory automation is another. Companies supplying testing and measurement equipment enable the construction of more energy-efficient buildings and the operation of cleaner factories and plants. France-based Schneider Electric, in the energy sector, is one such example.

Firms offering grey water recycling, solar and geothermal power systems and energy-efficient smart windows and floors support green architecture.

Wind power is a popular and well-reported alternative, renewable energy source. It is supported by various companies that design, build and supply components and automation equipment for offshore wind farm operators, such as Spain-based Iberdrola. Others provide the hardware and software that enable connection to the onshore grid.

Similarly, solar panels depend on an extensive supply chain before the technology can be deployed in residential and commercial buildings or a solar energy farm can be ‘planted’. Polysilicon, cadmium telluride, photovoltaic film, semiconductors, sensors and mounting infrastructure are among the elements in this supply chain, helping to make this technology more viable.

Legislative game-changers for clean energy

We think the impacts of the Inflation Reduction Act (IRA) on energy transition are game-changing. Comparable European legislation directs more than €200 billion toward accelerating energy transition plans.

The IRA earmarks approximately US$370 billion in federal funding to encourage investment in clean energy technology and initiatives through tax credits and other financial incentives. In our view, green hydrogen will benefit the most.

Green hydrogen: The alternatives’ alternative

Hydrogen is already used in manufacturing, refineries, chemical plants and fertilizer production. Removing pollutants from this ‘brown’ and ‘blue’ hydrogen (derived from coal and natural gas, respectively) would be prohibitively expensive and consume enormous amounts of fossil fuel-based sources.

On the other hand, renewable, or ‘green’ hydrogen, uses alternative energy sources in a cleaner, more efficient method of extracting hydrogen from water through electrolysis technology. Green hydrogen is a zero-emission alternative to other energy sources.

While its costs aren’t negligible, lower renewable energy prices and declining costs of the electrolysers used in the extraction process are making green hydrogen a more viable option. The World Bank estimates that like-for-like costs for green hydrogen and fossil fuel-based choices could reach parity by 2025.

We believe the environmental advantages and increasing popularity of green hydrogen will drive a long-term secular spending trend.

Don’t underestimate China’s role

In many ways, China’s progress toward energy transition is a model for the rest of the world. Its renewable capacity overtook coal capacity in 2022.

China boasts over 400 million middle-class consumers and almost half a billion drivers. It has nearly 80% of the world’s fast-charging EV stations and 60% of normal-speed EV charging stations, according to the International Energy Agency (IEA). Its progress toward energy transition will profoundly affect how quickly we move toward a net-zero environment.

China is currently the world’s largest producer of solar energy and the top exporter of solar energy equipment. Keeping with this renewables theme, it’s also the No. 1 producer of green hydrogen.

The nation produces about 33 million tons of green hydrogen annually, ahead of Saudi Arabia. Moreover, according to the IEA, China has pledged to bring 50,000 hydrogen fuel-cell vehicles online by 2025 as it accelerates the decarbonization of its economy.

It plans to increase annual green hydrogen production to 100,000 and 200,000 tons by 2050 as part of its first-ever hydrogen industry transition plan.

Europe, North America and India are also ramping up electrolyser manufacturing capacity. See Figure 2.

China’s commitment to increasing its supply and utilisation of green hydrogen should help drive demand for this technology and support the companies affected by its wider adoption.

This development supports our view that the energy transition will drive long-term secular spending as economies move to cleaner energy sources.
