The investment
MK PLUS is expanding its European activities through Vanadis Energy and MK Plus Sweden AB in Rosersberg, north of Stockholm. Following the acquisition of Enerpoly's assets, the company gained access to manufacturing equipment, industrial infrastructure, and experienced battery professionals. The investment creates a platform for the development and industrialisation of vanadium solid-state and zinc-ion battery technologies for stationary energy storage. In parallel, the company is advancing research collaborations, participating in Swedish innovation programmes, and preparing for future production scale-up.
Future growth plans
Vanadis Energy plans to continue developing and industrialising vanadium solid-state and zinc-ion battery technologies in Sweden. The company is expanding its collaboration with RISE, participating in publicly funded innovation projects, and building industrial capabilities in Rosersberg.
