The seven-year project will see Vestas and the Swedish technology firm collaborate on the research and product development of a storage solution, which could either be deployed into wind turbines or integrated into a "full power plant system design".
Using the programme, Vestas said it also wants to "develop and optimise control systems that can integrate battery storage systems with other renewable energy technologies".
"This important collaboration with Northvolt will enable Vestas to define, challenge and improve battery storage offerings for customers that need hybrid and storage solutions," said Vestas' chief technology officer Anders Vedel.
"There is a strong shared purpose and strategic fit with Northvolt that will support our goal to expand our knowledge in an area that we know will only grow in importance to the renewables and overall electricity market," Vedel added.
Northvolt signed an agreement with Swiss outfit ABB to share products and services involved in the development of battery solutions.
It is also building a lithium-ion battery factory in Sweden, with full production expected to begin in 2020.
"Batteries and solutions for energy storage are key in this transition, and Vestas will be an important strategic partner for Northvolt as we establish our product offering to the renewable energy sector," said Peter Carlsson, co-Founder and CEO of Northvolt.
In September, Vestas confirmed it was collaborating with battery firm Tesla, and other specialised companies, on developing storage solutions.
Since 2012, Vestas has developed a number of pilot hybrid or storage projects. It has previously said it is planning to bring a product to market by 2019.
