The global energy transition depends on more than clean power generation. It also needs stable and reliable grids. Finnish startup Halide Energy is tackling this challenge head on. The company has closed the first phase of a major funding round to advance its grid scale battery technology. Specialist investor BSV Ventures led the round. LAB7, the venture builder arm of Aramco, joined as a strategic participant.Solving Renewable Grid Stability IssuesCopper Based Battery InnovationStrategic Value of LAB7’s InvolvementEconomic and Environmental BenefitsEnabling the Future of Long Duration Storage The funding will help Halide move faster from development to market readiness. Solving Renewable Grid Stability Issues Solar and wind power continue to grow worldwide. However, both sources produce energy intermittently. This creates pressure on power grids. Utilities need solutions that store energy for long periods and release it when needed. Halide Energy focuses on long duration energy storage. Its mission centers on improving grid reliability while supporting renewable adoption. The company addresses key grid challenges such as: Energy supply fluctuations Demand peaks during low generation periods Long term storage for large scale systems These challenges continue to limit renewable expansion. Halide aims to remove those limits. Copper Based Battery Innovation Halide Energy has developed a Redox Flow battery system built around copper. Copper is abundant and low cost. This gives the technology a strong economic advantage. The system uses non flammable aqueous electrolytes. This design improves safety and simplifies operation. Key features include: High safety through non flammable materials Long operational life Stable performance at grid scale Lower material and production costs The technology supports extended energy storage. It also fits large infrastructure projects without complex safety requirements. Strategic Value of LAB7’s Involvement LAB7 brings more than capital to Halide Energy. The partnership offers deep expertise in scaling energy technologies. LAB7 also supports product refinement and commercial readiness. This collaboration helps Halide: Prepare for market entry Improve manufacturing plans Align product design with global demand LAB7 focuses on technologies that reshape the energy sector. Halide’s solution fits directly into that mission. Economic and Environmental Benefits Halide’s battery system targets cost efficiency at scale. The design reduces both capital and operating expenses. Simplified manufacturing lowers production costs. Reduced maintenance cuts long term spending. Benefits include: Lower total cost of ownership Easier deployment for utilities Reduced environmental impact Better support for renewable integration These advantages make grid scale storage more accessible. They also help utilities invest with confidence. Enabling the Future of Long Duration Storage Long duration energy storage remains a missing piece in many power systems. Halide Energy fills this gap. Its technology supports higher renewable penetration and stronger grid resilience. The successful funding round marks an important milestone. It signals strong investor confidence in practical energy innovation. With backing from BSV Ventures and Aramco’s LAB7, Halide Energy stands well positioned to support a cleaner and more stable energy future.
