Stena gives Volvo bus batteries a second life

The commercial service lives of bus batteries are significantly extended and natural resources are conserved. That is the result of a new cooperation between Volvo Buses and Stena Recycling subsidiary Batteryloop. After the batteries are removed from Volvo’s buses, they are reused as energy storage units for a number of years, for instance in buildings and charging stations.

“Volvo Buses is one of the pioneers in electromobility which provides clean, quiet and efficient public transport. We have a clear-cut sustainability strategy at every single stage of our value chain, and we are now taking yet another step forward through planned, consistent reuse of bus batteries. In our electromobility operation we are thus creating a new circular business cycle and this cooperation is truly a major step in the right direction,” says Håkan Agnevall, President of Volvo Buses.

Bus batteries are used for many years in regular traffic before they need to be replaced. However, when new batteries are fitted to the vehicle, the old ones still have considerable capacity left to offer. This capacity is too limited to efficiently propel a bus, but it is more than sufficient for static use for energy storage purposes. Repurposing the batteries means that natural resources can be conserved since it is not necessary to use new batteries for energy storage.

“We are delighted and proud that Batteryloop has the opportunity to buy the used batteries and develop this solution together with Volvo Buses. In addition to reuse, under the agreement we also guarantee safe and environmentally suitable recycling when the batteries come to the end of their second life as energy storage units. We thus offer a sustainable circular solution for Volvo Buses batteries. What is more, this cooperation means we can convert a cost into a source of revenue for the customer,” says Rasmus Bergström, Managing Director of Batteryloop.

The new recently signed agreement has a global reach. It covers all the batteries for which Volvo Buses is responsible in its electric buses the world over. To date most of these buses are to be found in Europe, but the number of electrified buses is expected to increase in other parts of the world too.

“We see a steadily increasing demand for electric buses from cities all over the world, and since we entered the electric bus market early, the numbers of used batteries are set to increase,” explains Håkan Agnevall.

The demand for local energy storage units is expected to increase in the future. Not least, an energy storage unit offers new scope for storing renewable energy, which can be used to meet peaks in electricity demand. Any surplus can be sold, delivered straight into the grid.

“An energy storage unit is like a large power bank that gives the user considerable flexibility and can help generate income. We see that there is a fast-growing market in different kinds of properties, and also for charging stations for electric vehicles both in industry and in society. Our cooperation with Volvo Buses will provide a valuable contribution to development of the infrastructure that needs to be built up,” comments Rasmus Bergström.

Batteryloop and Volvo Buses have already previously been involved in a joint project with Stena Fastigheter, whereby bus batteries are used as energy storage units to provide electricity to the Fyrklövern residential area in Gothenburg. The electricity that is stored in these units comes from solar panels fitted to the apartment buildings’ rooftops.

New collaboration provides real estate electricity from bus batteries

New collaboration provides real estate electricity from bus batteries

A new collaboration between Volvo Buses, Stena Real Estate and Stena Recycling’s subsidiary Batteryloop was presented December 11. The mutual project gives new life to bus batteries in solutions for energy storage. After several years in traffic the batteries are converted to serve as an energy storage at Stena Real Estate’s residential area Fyrklöversgatan on Hisingen in Gothenburg.

The background for the collaboration is the ongoing significant increase in use of batteries, especially in the automotive industry. There is a huge need of ways to take care of these batteries in a sustainable way. This collaboration places Gothenburg at the forefront for the reuse of vehicle batteries.

− Volvo Buses are pioneers in electromobility, providing a clean, quiet and efficient public transportation system. We have a clear sustainability strategy at every stage of the value chain. By reusing the bus batteries and giving them a second life, we use resources better, reducing our climate impact, says Håkan Agnevall, CEO, Volvo Buses. Electromobility creates new circular business systems and it is really rewarding to work with Stena Real Estate and Stena Recycling in developing this new business, he adds.

In the ​​Stena Real Estate’s residential area, the refurbished batteries will be charged from solar cells on the roofs. The stored energy will be used for public spaces such as laundry rooms and for outdoor lighting. For Stena Real Estate, it is part of the strategy for sustainable construction and to find new energy sources.

− For us, it is about working with circular flows and resource efficiency, from an environmental perspective. Connecting solar cells and reused batteries is a way to drive development. The same infrastructure can be used to handle several different challenges, among others improved power control and energy storage in buildings with local production, as well as stabilizing functions for an evolving electricity grid, says Agneta Kores, MD Stena Real Estate Gothenburg.

After several years of use in traffic, the capacity of the batteries is no longer optimal for operating a bus but can still meet needs in other areas. From the cells in the used bus batteries, Batteryloop builds energy storage. Later, when the cells’ capacity for energy storage is exhausted, they go to recycling. Being at the forefront and driving the development for circular solutions in different areas is part of Stena Recycling’s business concept.

− We have extensive experience of working with both reuse and recycling in several areas. As the use of vehicle batteries will increase significantly in the future, there is a great market need for a player like Batteryloop. A company which can ensure that the batteries are taken care of in a sustainable way, both in terms of reuse and of recycling, says Rasmus Bergström MD of Batteryloop.
