The City of Stockholm is the first among Sweden’s municipalities to operate a fully electrically-powered truck. The vehicle, which is charged with renewable electricity, transports construction equipment and excavated masses as part of the Stockholm Royal Seaport urban development project.
The electrification of construction sites has considerable potential to reduce the construction sector’s overall climate emissions. In order to increase knowledge about the use of electric vehicles on construction sites, an electric truck was trialled in the spring of 2022 in Stockholm Royal Seaport. The tests included battery storage that quickly charges the truck.
Powered with renewable electricity
An all-electric truck is currently in use on the streets of Stockholm Royal Seaport. The truck – the first of its kind in the country – will transport construction equipment and excavated masses around the site and handle deliveries to the Construction Consolidation Centre. “An electric truck is a long-awaited addition to the project. Transport currently accounts for a third of Sweden’s total greenhouse gas emissions, and as a special sustainability zone and testbed for innovations, electric transport is well aligned with Stockholm Royal Seaport’s goal of being fossil-free by 2030,” says Fredrik Bergman, Head of Implementation, Stockholm Royal Seaport. The truck is charged with renewable electricity, which reduces greenhouse gas emissions by 86% throughout its lifecycle. As it runs on electricity, the truck is also silent and thus does not disturb local residents and businesses. The battery capacity is 300kWh, which corresponds to one day’s driving in and around the site. “The results of the trial will form the basis of economically and environmentally sustainable electrification solutions. This will be of value for the development of Stockholm Royal Seaport and contribute to knowledge in Sweden about how electrification solutions can look and function on construction sites” Fredrik Bergman adds.
Positive driving experience
The truck is being tested for transports to and from the Construction Consolidation Centre that supplies Stockholm Royal Seaport with construction equipment. It will also transport excavated masses. Fredrik Rundqvist is driving the truck during the trial period and likes the quality of the ride. “You get a smooth ride because the electric motor is less jerky and quieter than the trucks I usually drive. I also avoid breathing in exhaust fumes when loading and unloading,” says Fredrik Rundqvist.
Electrical supply is a key issue
The project is set to help identify ways to secure the supply of electricity – a key issue in efforts to electrify the construction sector. “A construction site involves the transport and processing of masses and construction activities, processes that have considerable energy and power requirements. If, based on these tests, we can learn how to maximise capacity by working creatively, we have a lot to gain,” says Fredrik Bergman. The truck is the first of its kind, and the City of Stockholm is thus the first among Sweden’s municipalities to test an all-electric truck. In order to handle different types of deliveries, the truck is equipped with a unique load changer system that minimises energy consumption and includes three different types of load platforms – one for excavated masses, one flatbed with a mounted crane, and one covered version with a rear lift to safely deliver construction equipment. This creates flexibility to perform the right task for the right part of the project. The project is part of a testbed under the Vinnova initiative on charging infrastructure for heavy electric vehicles “With a view from the driving seat – how can electric vehicles work in the system?”, which runs until the second quarter of 2022.
