INFRAMAG for the future transport
The most important aspect now and in the future is the energy cost, of course in harmony with all environmental aspects. The consumption of energy must be the lowest imaginable considering that it is constantly consumed, must be renewed over and over again. If we can reduce the energy used to a minimum, much has been gained. We have been spoiled with petrol/diesel which contain a lot of energy and at really low costs.
A somewhat simple comparison that ordinary people can understand. An ordinary 85 Ampere-hour starter battery that is normally installed in ordinary cars contains the same amount of energy as 1 dl of diesel/petrol, i.e. a cup of coffee. Now if we look at a truck with a large tank 600 liters. If it is to be replaced with a battery of equivalent efficiency, the battery must last 6000 kWh.
In the premium sedan Tesla Model S 100 D, the battery weighs a whopping 625 kg due to the heavy battery of 100 kWh. Here we are talking about an effect that is 60 times as great, which would give a battery weight corresponding to 37.5 tons. That weight will remain at all times and reduce the paying weight of the goods on the truck, it does not exist at all either. Could this be a real option? The truck is completely undriveable and only consists of enormous battery weight + the tare weight of the truck. We strongly doubt trucks in the future! Their time is over and will only exist as delivery trucks.
There is no doubt that energy consumption will be decisive. There is then reason to look completely unconditionally at the possibilities that may come into question for the transport of goods. We stop here with a comparison between terrestrial transport systems.
Transport with track-based solutions.
Transport with wheeled solutions.
Because trucks have a speed that is < 90 km/h. The railway largely similar speeds, there are exceptions on higher speeds. One factor that dominates in that speed range is rolling resistance. Air resistance begins to affect speeds above that. There is a generally accepted practice in comparisons between truck and rail. To transport unit 1 by rail, the factor is 1 and by truck 15. To get the real energy consumption, you have to divide by the vehicle's efficiency, to find out what comes out in the wheels of each vehicle.
Transport vehicles | Efficiency | Energy consumption |
Railway, Locomotive | 0,85 -0,94 | 1,2 – 1,1 |
Truck with diesel engine | 0,2 | 75 |
Truck with electric motor | 0,35 – 0,45 | 43 - 33 |
Modern trucks such as Einride | 0,35 – 0,45 | 43 - 33 |
Vehicle | Speed today km/h | Speed tomorrow km/h |
The railway | 70 - 110 | 250 - 320 |
Trucks, diesel and electric motors | 80 - 90 | 80 - 90 |
Modern truck eg Einride | 70 - 90 | 70 - 90 |
If you look at the numbers, all transport in the future will take place with track-based solutions. Anything else is not economically, energy and time justifiable. You can also see that it is possible to save large amounts of energy by carrying out the transports by rail.
Now the truck has to enter at the end and at the beginning of almost every transport relationship of goods with the railway. With automatic reloading stations, the reloading cost can be kept down to SEK 100 - 125 per handling. With close terminal location and short distribution distances, both energy and time aspects can meet a future challenge in transport and logistics.
A long-haul truck has a tank of approx. 600 litres. This corresponds to an energy content of approx. 6000 kWh. Such large batteries are not available at all for the automotive industry. They would also cost enormously and be extremely heavy. If you use Tesla as a comparison, battery 100 KWh, weight 625 kg. In this case, there would be 60 batteries, which would not have room and also weigh 37.5 tons, which is completely impossible. The vehicle is completely undriveable.
The solution that is now advocated from the truck side is that the truck should be able to be driven for 3 or 4 hours, with an interruption of 45 minutes for rapid charging. This is of course to keep the weight of the heavy batteries down. Will of course not work for medium-long transports. It can work within a distribution distance that can be accommodated within the time 3 to 4 hours/2 ie the truck has to return as well. In the future, trucks will be located in distribution traffic only. You can also see that it is possible to save large amounts of energy by carrying out large parts of the transports by rail. (consumption for the railway figure 1.2 in comparison with road-bound vehicles 35 – 75).
Now almost every transport relationship of goods by rail, at the beginning and at the end, must be carried out by trucks (distribution vehicles) to get to individual customers. With automatic reloading stations, the reloading cost can be kept down to SEK 100 - 125 per handling of the unit load container. With close terminal location and short distribution distances, both energy and time aspects can be optimized and meet a future challenge in transport and logistics. Trucks can't, even if they're electric.
Even if there were to be a fantastic development on the battery side, it will always remain: it is at least 15 times more expensive in terms of energy to transport goods with wheeled vehicles. It is time to realize that the truck as a means of transporting goods, for medium and long hauls, is not an option in the future, whether they are called Volvo, Scania, Mercedes but also the now developed modern alternatives such as Einride.
In addition, there remains the great environmental nuisance that exists with wheeled vehicles that negatively affect humans, for example the very small rubber particles that come from tire wear and that result in a large number of people's premature deaths per year.
Future freight transport structure.
How will the future transport structure develop in consideration of the fact that the truck cannot participate in medium- and long-distance transports, which is explained above and is completely unfeasible. We are facing a major change in the future transport structure. The only thing that will work is for all the long-distance transport of goods to be transferred to rail transport. In consideration of the electrification that is to be carried out, the future transports should be set up as intermodal transports and that it is only handled by the unit load container. At the same time, it would provide opportunities to implement that the traffic takes place according to an efficient route layout and not, as now, end-point traffic.
Several smaller terminals with the distance between the terminals of 15 miles, which means that there are opportunities to carry out the distribution with the help of electrically driven distribution vehicles. A finely meshed and efficient transport network that can meet the higher requirements for low energy consumption and low CO2 emissions. The environmental requirements for a future structure are met. This will of course require an expansion of the existing railway network. There really isn't any other option.
To sum up, the authorities would not achieve the extensive expansion of the electrical grid that is requested from the truck manufacturers. Instead, the authorities would make sure to greatly expand the possibilities of transferring goods transport to become rail-bound. In this way, a smooth transition to truly energy and environmentally efficient transport would be achieved.
