Pesa unveils a hydrogen diesel locomotive based on the SM42!
Pesa Bydgoszcz presented its hydrogen locomotive at TRAKO. This is a modernized locomotive with installed hydrogen cells.
PESA just did as promised. The first Polish hydrogen locomotive is presented at TRAKO. The unit itself visually underwent a significant modernization, because its basis was the SM42 diesel locomotive.
The entire project was created in collaboration with PKN Orlen and Orlen Koltrans. This particular locomotive will soon be put into operation at the Orlen refinery in Plock.
The locomotive manufactured by Pesa has four 180 kW asynchronous motors each, an auxiliary converter 3 x 400 V, one inverter for two traction motors. A traction battery based on LTO technology with a set of hydrogen cells will be used for the entire drive.
The diesel locomotive with the designation SM42 6Dn is a 4-axle locomotive with 4×180 kW traction motors. It was equipped with an innovative energy source – a zero-emission hydrogen engine. Two Ballard hydrogen cells are responsible for power generation.
An 85 kW cell is a system that generates electrical voltage through the chemical reaction of hydrogen with oxygen from the atmosphere. Hydrogen is taken from hydrogen tanks and fed into the cell after passing through a pressure reducer at a pressure of 8 bar.
The hydrogen cell power system consists of two sets of tanks installed in a steel frame. Each of them contains 16 cylinders, and the total capacity of 32 hydrogen cylinders is 175 kg for a pressure of 350 bar and a gas temperature of 15 degrees Celsius. The locomotive drive system also includes a large capacity traction battery. The batteries are supplied in 6 separate boxes, connected by an electrical installation and a cooling system. The battery is made using LTO technology, with a total capacity of 167 kWh.
The locomotive has also been equipped with an autonomous driving system that allows one driver to drive the vehicle as well as an obstacle recognition system. After modernization, the SM42 6Dn acquired not only an innovative drive, but also a modern design, its minimalistic style refers to current trends.
The most important change is the relocation of the driver’s cab to the central part, which is double-sided, has a social area and an air conditioning system. Due to the increased technical part, the side platforms were removed and the entrance was moved.
