PESA, the leading Polish producer of rolling stock, has made significant strides in sustainable transportation by developing a hydrogen-powered shunting locomotive.
This groundbreaking project involves the modernization of their SM42 unit, and the knowledge gained from this endeavor will serve as a foundation for the construction of a passenger vehicle with a hydrogen drive—the PESA Regio160.
The SM42 6Dn locomotive is a 4-axle shunting locomotive with 4x180kW traction motors. It incorporates two 85 kW hydrogen fuel cells that generate electricity, making it an environmentally friendly alternative to traditional diesel locomotives. Notably, the locomotive is equipped with an autonomous driving system, enabling a single driver to control the vehicle during train setup, along with an obstacle recognition system to prevent collisions.
One significant design change in the SM42-6Dn locomotive is the relocation of the driver’s cabin to the middle of the vehicle, enhancing visibility and operational efficiency. The hydrogen cell power supply system comprises two 16-tank packages mounted in a robust steel frame, providing ample storage capacity. With a maximum refueling time of up to 30 minutes, the locomotive is capable of swift and efficient hydrogen replenishment.
In addition to the hydrogen fuel cells, the locomotive incorporates a high-capacity LTO (Lithium Titanate Oxide) traction battery with a total capacity of 167 kWh. This battery system provides supplemental power and supports the locomotive’s operations, further enhancing its efficiency and range.
The introduction of a hydrogen-powered shunting locomotive carries significant implications for the transportation sector. By utilizing hydrogen as a clean fuel source, the locomotive eliminates harmful emissions associated with traditional diesel-powered engines, such as particulate matter and greenhouse gases. This advancement aligns with global efforts to reduce carbon footprints and transition to sustainable modes of transportation.
The potential impact of hydrogen-powered locomotives extends beyond environmental benefits. These vehicles offer quieter operation, reducing noise pollution in urban areas and enhancing the overall passenger experience. Moreover, hydrogen-powered trains have the potential to operate on non-electrified tracks, providing a versatile and efficient solution for various railway networks.
While the development of hydrogen-powered locomotives presents a promising opportunity for the transportation industry, several challenges must be addressed. Infrastructure for hydrogen refueling stations needs to be established to support the widespread adoption of hydrogen-powered trains. Additionally, the cost of hydrogen production and storage infrastructure remains a hurdle that requires further investment and technological advancements.
Nevertheless, PESA’s breakthrough in developing a hydrogen-powered shunting locomotive sets a significant precedent in the industry. It showcases Poland’s commitment to sustainable transportation solutions and contributes to the global shift toward greener, more efficient rail systems.
