Stena is to use recycled batteries in charging stations located at ports.
The ferry company said that the development of a new type of energy storage, similar to very large powerbanks, will be essential for the quick charging of future electric powered ferries.
Part-financed by the EU, the project will, among other things, investigate how used batteries from the transport sector can be reused for energy storage in ports.
“An incredible amount is happening in the world of batteries. New solutions are being designed to meet the charging requirements of the transport sector of the future, especially for shipping where vessels are starting to switch to electric power. “Rapidly charging a large ferry, for example, requires a huge amount of energy in a short time and it’s not certain that the electricity grid will be able to deliver it. Local energy stores at ports could offer a great solution to this problem,” Rasmus Bergström, Managing Director of Batteryloop, explained.
Batteryloop is a subsidiary of the Stena Recycling Group. The company has claimed to have made an impact in electrification, not least in the recycling of used batteries from the automotive industry.
A global collaboration agreement was recently signed with Volvo Buses, to reuse the batteries from its electric vehicles.
“One thing is sure, batteries are here to stay. In order to conserve natural resources and make battery recycling sustainable, we need to do everything we can to use batteries for as long as possible. Our conclusion is that many batteries can have a second life as energy storage. If we can find solutions that will scale-up and work in ports, we’ll have a win-win situation in many ways,” Bergström added.
Opportunities to reuse lithium-ion batteries from the transport and automotive industry for energy storage in ports – to charge electric ferries, for example, will be mapped and evaluated.
A collaborative project, the companies involved include several Stena subsidiaries – Batteryloop, Stena Recycling, Stena Rederi and Stena Line – the ports of Gothenburg and Kiel, plus DNV GL.
The work will be carried out over two years and will be part-financed by INEA, the EU’s Innovation and Networks Executive Agency.
In 2018, Stena Line started to invest in battery power on the ferry ‘Stena Jutlandica’, which uses battery power to drive the bow thrusters when steering the vessel into port.
“This is an important milestone in the electrification of shipping. Our future project, Stena Elektra – a fully electric ferry – is already on the drawing board. In order to succeed, we need to solve the issue of how to quickly charge a ferry.
“Energy storage at ports using recycled batteries, is a very interesting and sustainable alternative for the future,” said Per Wimby, project manager for electrification at Stena Teknik.
Quayside energy storage can also be used as an alternative power source for vessels in port, which will reduce greenhouse gas emissions. For example, all Stena Line ferries are today connected to green onshore power in Gothenburg.
Batteryloop builds energy stores from batteries and ensures the recovery and recycling of batteries that are no longer in use. Through Stena Recycling’s branch network, Batteryloop can receive batteries directly from manufacturing companies, repair shops, car dismantlers and insurance companies.
