Latest proven technology
Rolling stock owners and suppliers can count on Alstom’s research and development capabilities, supported by long-standing experience. The company’s green propulsion solutions incorporate the latest battery and/or fuel cell technologies and benefit from simulation tools and stringent validation procedures, ensuring that customers receive the latest proven technology to power both Alstom and non-Alstom trains.
Furthermore, Alstom benefits from in-house design, development, manufacturing, engineering support and customer training capabilities for fuel cells through Helion Hydrogen Power, a subsidiary involved in more than 100 projects with 30 solutions in operation worldwide.
Large offering matching customer needs
Alstom offers a large portfolio of green traction products for hydrogen, battery, hybrid and bi-mode catenary + hydrogen applications. The portfolio includes new and refurbishment options. Customers can draw on Alstom’s expertise to determine the best solution for their needs. Solutions can be flexibly adapted using standard and modular alongside optimization tools. Green traction products, in most cases, give better performance and comfort than a comparable diesel train.
Alstom’s solution to reduce customers’ carbon footprint
Alstom’s portfolio is designed to lower CO2 emissions. With great traction performance, a wide range of autonomous operation options, Alstom can even offer an improved service compared with diesel alternatives. Energy regeneration during braking makes the portfolio even more efficient.
Existing fleet modernisation
Alstom provides onboard energy storage products and services as sustainable retrofit solutions replacing, or combined with, diesel traction. Refurbishing trains during scheduled overhauls, these solutions improve the existing fleet and avoid a costly electrification upgrade.
The on-board battery energy storage system is installed as an additional package and can fit any rail vehicle including LRV, regional and commuter trains and locomotives.
