Sustainable intermodal refrigerated rransports: main study

Shipments of temperature sensitive goods imply environmental impact through the energy that is consumed in both the transport and temperature control of freight carriers and goods. Temperature control means that the temperature of the carrier is adapted to the cargo requirements by heating (heat), cooling (cooling) or refrigeration (freezing). The current TFK study "Sustainable refrigerated transports" has the aims to identify existing temperature control solutions for land transport. The study has revealed that temperature control is costly and creates significant environmental impact. A contributing factor to this is that the equipment used for temperature control usually is diesel-electric. Moreover, the demand for quality and reliability is high. From an environmental and quality point of view, it is of great interest to investigate alternative solutions for energy as these temperature control units have poor environmental performance. This is particularly true for intermodal shipments as the relative impact of temperature control becomes high due to the use of electric locomotives on rail. It is usually possible to run existing diesel-electric generator sets with 3-phase 400V electricity, common practice in sea transports. The aim of the project is to create good conditions to increase the share and the amount of temperature controlled goods transported intermodally by developing sustainable and cost-effective systems for temperature control where energy is supplied in a more environmentally friendly way and in also better in terms of quality and cost compared to today. One goal is to create opportunities to supply the temperature control equipment electrically (minimize diesel) in the different parts of an intermodal transport chain. This includes studying the obstacles / opportunities for introducing new systems of energy supply which may include organizational, technical, safety and quality related aspects. Within the study a demonstration is planned in which a system for electrical distribution of the intermodal train is implemented and subsequently analyzed in terms of environmental, marketing and quality aspects. Operators and cargo owners are expected to cooperate in a test of the solution and subsequently TFK will evaluate the solution. Other issues referred to be treated are accountability, systems for temperature monitoring (including remote monitoring and control) as well as key factors for the viability and economic sustainability in temperature controlled intermodal transports. Overall, the planned activities are expected to enable improvement of efficiency and reduction of environmental impact through more sustainable energy supply in refrigerated, intermodal, transports. In addition, enabling quality improvements is intended to create greater competitiveness and growth for these solutions. Mainly, the project is intended to demonstrate solutions for power supply during rail transport as well as deployment at terminals, yards and other sidings in intermodal transport chains. All in all providing emission reduction in intermodal transport chains by reducing the diesel usage.
