MARKET RESTRAINTS

Competition from Electrification and Hydrogen Could Restrain Market Expansion

In regions with extensive electrified rail networks, such as Europe and parts of Asia, trains primarily draw power from overhead catenary systems, reducing the need for large traction batteries. Simultaneously, hydrogen fuel cell technology is gaining momentum as a zero-emission alternative, especially for non-electrified routes where full electrification is costly. Several countries, including Germany and the U.K., are deploying hydrogen trains with longer ranges and faster refueling compared to battery-electric models. This dual competition limits investment and slows the adoption of battery-based solutions, constraining market expansion opportunities globally.

• In September 2025, Sierra Northern Railway unveiled the U.S.’s first hydrogen-powered switcher locomotive in West Sacramento, funded by USD 23.5 million. The zero-emission train replaces diesel units, cutting fuel use and emissions while supporting California’s clean transportation transition.

MARKET OPPORTUNITIES

Advancements in Lithium-Ion and Solid-State Technologies to Create Lucrative Growth Opportunities

Lithium-ion batteries deliver higher energy density, longer life cycles, faster charging, and reduced maintenance compared to traditional lead-acid and nickel cadmium battery chemistries. This makes them highly suitable for modern rail applications, including hybrid and battery-electric multiple units. Solid-state batteries, still emerging, promise even greater safety, higher energy efficiency, and improved operational reliability, which could revolutionize traction and auxiliary power systems in advanced trains. As rail operators seek cost-effective, sustainable, and high-performance energy storage solutions, these next-generation train battery technologies open avenues for innovation, new product launches, and long-term growth, especially in electrification and non-electrified route operations.

MARKET CHALLENGES

Supply Chain and Raw Material Constraints to Challenge Market Growth

Advanced rail batteries rely heavily on lithium, cobalt, and nickel, materials concentrated in a few regions such as the Democratic Republic of Congo, Chile, and Indonesia. This geographic dependency exposes manufacturers to price volatility, export restrictions, and geopolitical risks, which disrupt stable supply. Additionally, rising global demand from the electric vehicle sector intensifies competition for these critical minerals, further tightening availability. Such uncertainties hinder long-term procurement planning for rail operators and increase production costs, making it difficult to scale the adoption of advanced battery technologies.

To address this issue, in March 2025, the European Union allocated EUR 1.8 billion (USD 1.94 billion) to strengthen the supply chain for battery raw materials, addressing the shortage of critical components such as lithium and cobalt. This initiative aims to bolster the EU's battery manufacturing sector and reduce dependence on external sources.
