Coolergy, a Spanish company specializing in cryogenic and gas chemical technologies, has teamed up with Czech engineering firm Aurora Engineering to convert 12 TGМ4 diesel locomotives of Latvian company DZ Loko to hydrogen traction and establish infrastructure for liquid hydrogen production. The project involves incorporating hydrogen fuel cells from Toyota, with each locomotive set to be equipped with four 80 kW fuel cells. Aurora Engineering's track equipment experience and Coolergy's expertise converge to drive this initiative, aiming to revolutionize the railway industry's environmental impact. Besides reducing harmful emissions, the project will create a blueprint for hydrogen technology integration in rail transport globally. Through the establishment of hydrogen infrastructure and refueling stations, the partners are committed to ensuring the seamless operation of the revamped locomotives. This collaboration signifies a significant leap towards sustainable transportation and showcases effective international cooperation in cutting-edge industries. The joint effort not only promises a greener future for railway operations but also serves as a model for successful high-tech partnerships. The broader goal is to extend the project's success to other countries sharing a similar railway gauge, potentially transforming the approach to rail transport on a global scale.
