In parts of the world, heavy duty commercial vehicles are usually restricted from driving at night due to noise. Most notably in Stockholm, the don’t allow these types of vehicles to drive through the city centre at night and delivery access often takes places when shops and restaurants are preparing for the start of the day’s business. As this is during the morning rush hour, a new pilot study to test silent overnight deliveries has been introduced.
Taking place at six McDonald’s restaurants in Stockholm, Sweden have been using a hybrid truck from Scania that is operated by HAVI. The deliveries are being sent via silent electric powered vehicles in an attempt to minis delivery trucks getting stuck in traffic and causing delays.
The way it works is a chargeable hybrid truck from Scania runs with a combination of electricity and fossil free fuel. Not only does it eliminate noise, it also dramatically reduces the emissions of particles and carbon dioxide. In addition to this, the plug-in hybrid truck also utilises geofencing technology. This means it has the ability to adapt itself to the driving conditions in a predetermined area. Virtual traffic zones help the vehicle determine which mother the vehicle will use and can adapt its speed to the real-life speed limits.
The city of Stockholm are cooperating with HAVI, KTH, UE, McDonald’s and Scania for the this initiative and it is also part of a wider project in the EU: Eccentric Stockholm. The hybrid truck currently has the ability to drive in silent electric mode for up to 10 kilometres and can ‘efficiently deliver goods on practically empty streets at night’.
The battery is charged by external power sources and via regeneration. This means that the truck’s movement is turned into electricity each time the brakes are used. The restaurants also have electrical charging stations near by meaning the truck can charge its battery while loading, unloading, and during driver breaks ensuring it won’t run out of power and disrupt people in the city centre.
When longer routes are necessary, the vehicle can run its internal combustion engine on HVO which boasts 90 percent reduction in emissions. Thanks to software tools from Scania, the truck can change over automatically to quiet and emission free electric power when arriving in environmentally sensitive urban areas. They truly have thought of everything.
The team behind the project will be studying how much of an environmental benefit is gained by not having trucks in traffic queues and we can’t wait to read all about it!
