SLDBatt: Netherlands' €30M Initiative to Revolutionize Long-Duration Renewable Battery Storage
November 14, 2025
The project plans to demonstrate and commercialize longer-duration battery solutions, with a focus on knowledge sharing, accelerating the battery value chain, and building a national program for new materials, production technologies, and recycling.
SLDBatt stands for Sustainable Long Duration Battery Technology and operates under the Growth Fund for Material Independence & Circular Batteries, coordinated by BCC-NL, with participation from three technical universities, a university of applied sciences, three technology development companies, and two international firms.
The Dutch consortium has secured over €30 million in funding, including more than €20 million from the national Growth Fund, to speed up long-duration battery innovation in the Netherlands.
SLDBatt is described as the largest initiative of its kind in the Netherlands, bringing together a consortium of Dutch knowledge institutions, startups such as AQUABATTERY, Elestor, and Exergy Storage, established companies like Nobian, and international partners including RWE, coordinated by the Battery Competence Cluster NL.
The program targets lowering the cost of renewable energy storage, boosting domestic production of next-generation batteries, and reducing reliance on rare materials through advances in materials, components, production technologies, and recycling methods.
A Dutch project called SLDBatt aims to develop sustainable long-duration battery systems capable of storing renewable electricity for 8 to 100 hours, strengthening grid resilience, energy security, and circularity in the Dutch battery supply chain.
Leaders emphasize SLDBatt’s potential to prevent grid congestion, enhance energy security, and position the Netherlands as a European and global leader in sustainable energy storage.
