Chinese batteries are becoming an integral part of the Danish electricity grid. Despite previous political opposition to Chinese technology companies such as Huawei, large battery plants from the Chinese manufacturer Catl are now being installed in Kolding, Korsør and on Bornholm, among others. According to Andreas Bøje Forsby, senior researcher at the Danish Institute for International Studies (Diis), there are security risks associated with letting Chinese actors contribute to critical infrastructure. This is reported by Børsen.
- It could pose a potential security risk, and considering how conflict-ridden our relationship with China has been in recent years, we should be very careful about making ourselves dependent and vulnerable to China, and certainly not when it comes to the electricity grid, which is critical infrastructure, says Andreas Bøje Forsby, a senior researcher at Diis.
Experts from both the Danish Technological Institute and the Technical University of Denmark share Forsby's concern and points out that the control systems in the battery plants can potentially give the manufacturer access to data and control. In the US, the manufacturer Catl has been blacklisted from supplying the Ministry of Defense from 2026, and in Europe there is a warning about dependence on Chinese technology.
However, the energy provider Ewii believes that the danger is exaggerated. Here, it is stated that it is practically difficult to avoid Chinese batteries, and it is pointed out that Ewii has replaced Catl's control system with one developed in-house. Ewii also points out that it follows current safety assessments.
- As long as they allow us to buy the batteries in China, we must be careful not to conduct our own foreign policy and make our own crazy assessments in this area, says Lars Bonderup Bjørn, CEO of Ewii.
