Sustainable Green Rail Systems for Decarbonized Trains and Infrastructure

transportTestedTRL 7

Imagine replacing old, smoky diesel trains with versions that run on batteries or hydrogen, like a giant electric car for the tracks. It's not just about the trains, but also making stations cleaner and reducing the noise that wakes up neighbors. The goal is to make rail travel as green as possible while ensuring the parts can be recycled at the end of their life.

The business problem

What needed solving

Railway operators face pressure to eliminate diesel emissions and reduce noise pollution while meeting strict 2050 climate neutrality targets. There is a lack of commercially viable, standardized battery and hydrogen systems for regional rail.

The solution

What was built

Battery modules, traction system prototypes, and hydrogen refueling simulations for trains and stations.

Who can put this to work

Rolling Stock Manufacturing
enterprise
Target: Train manufacturer

If you are a train manufacturer dealing with the phase-out of diesel engines — this project developed battery and hydrogen power plants that allow regional trains to run without fossil fuels. This enables the production of zero-emission vehicles for the 2050 climate neutral goal.

Energy Infrastructure
mid-size
Target: Hydrogen refueling station operator

If you are an infrastructure operator dealing with the lack of fueling standards — this project developed H2 refueling simulations and safety rules. This ensures a faster and safer rollout of hydrogen stations for rail networks.

Waste Management
any
Target: Industrial recycling firm

If you are a recycling firm dealing with complex railway waste — this project developed circular economy and recyclability standards for train interiors and components. This creates a viable economic model for recovering materials from old rolling stock.
