Item Estudio técnico económico del uso de hidrógeno y amoníaco verdes en transportes de ferrocarriles en Chile.(Universidad de Concepción, 2025) Bao Mora, Mario Alfonso; Márquez Romegialli, Fernando; Carrasco Moraga, Juan CarlosThis thesis presents a technical-economic study of the use of green hydrogen and ammonia as fuels in railway transport in northern Chile. This study is based on bibliographic searches, carrying out energy balances, fuel consumption calculations and equipment cost calculations for their proper implementation, and in this way making a comparison between the three fuels. This study is based in part on the FCAB train, from which the most important characteristics of this train are extracted, such as its power, weight, speed, travel, etc. The green hydrogen train is composed of a fuel cell system and power batteries. For its part, the green ammonia train is mainly made up of a system called Amogy Powerpack, which is an integrated system of a cracking reactor, an absorber and fuel cells. Green hydrogen has an energy efficiency of 59%, which is much higher than the efficiencies of green ammonia and diesel, as reflected in the low number of kilograms of green hydrogen needed to make a certain journey. In terms of annual fuel costs and their transportation, green ammonia is the one with the highest values for these annual costs. For the costs of equipment and tanks specific to each train, the one with the highest costs is green hydrogen, and this is largely due to the high pressure at which this fuel is stored. Despite the technical and economic challenges identified, the results of this study demonstrate that the adoption of green hydrogen and ammonia in rail transport in northern Chile represents a viable and sustainable alternative over time.
