The Batteries business unit in Hydro Energy develops current assets and explores additional business opportunities within the battery value chain.


During the last years we have engaged in selected ventures within battery and energy storage. An overview of some of the engagements is listed below.

The investments were made to learn through active ownership, and we selected ventures that combined high value potential with opportunity to learn and contribute as an active owner. With these investments we already have a strong track record and a healthy growth potential.  

The battery sector is expected to grow very fast globally and in Europe, mainly on the back of the ongoing automotive industry transformation from fossil fuel to electrical vehicles.  

There is demand for a sustainable European battery value chain, and Hydro and Norway is well placed to take significant positions in this sector. Our dedicated team will systematically build competence through hiring of experts, and actively develop and expand Hydro’s battery footprint.   

We aim to explore new growth in areas where our capabilities match the global megatrends,  says Hilde Merete Aasheim, CEO & President.
