Critics and industry analysts express caution regarding the widespread adoption of hydrogen trains, citing significant economic and logistical hurdles. While the technology is environmentally promising, the upfront costs for hydrogen fuel cell systems, specialized storage, and dedicated refueling infrastructure remain substantially higher than traditional electric or diesel alternatives. There are also concerns about the energy efficiency of the hydrogen supply chain, particularly the need for large-scale production of green hydrogen to ensure the entire process is truly carbon-neutral. Until the costs of hydrogen production and infrastructure deployment decrease, some experts argue that focusing resources on expanding standard electrification might provide a more immediate and cost-effective impact on reducing the railway's overall carbon footprint.
