The Danish startup Gridturn, which extends the life of used electric car batteries by converting them into certified battery energy storage systems (BESS), has received 75,000 euros in support from the Women TechEU program.

This is reported by Energy Cluster Denmark.

The program supports female-led European technology companies with the potential for significant innovation and sustainable transformation. Gridturn's solution reduces waste and the need for new materials.

- 40 percent of the world's conflicts since the 1960s are related to the fight for raw materials. 90 percent of our biodiversity loss is related to raw material extraction, and we recycle far too little. In Europe we are at 12 percent circularity, in Denmark we are down to 4 percent. We must succeed in changing that, says Gridturn CEO Louise Witt Sengeløv to the cluster organization.

The company wants to reduce waste and the need for new raw materials by giving electric car batteries a "senior life".

- The range is crucial for a car battery, and therefore a reduction to 80 or 85 percent capacity effectively helps to retire the battery. But even with 80 percent capacity, the battery can easily function and bring value if you place it in a different context. The batteries will do very well in our system. The ideal senior life, she says.

The company recycles the batteries for BESS solutions that integrate with existing energy systems and contribute to balancing the electricity grid.

- We hold the key to Europe's future energy independence, says Louise Witt Sengeløv.
