Eclipse has developed an ultra-compact, plug-and-play energy storage module designed to stabilize the power grid and address one of renewable energy’s biggest challenges: intermittency. Unlike traditional battery systems, Eclipse’s patented technology stores energy in the form of compressed air and heat – a novel approach combining mechanical engineering and thermodynamics. The result: a safe, durable, and scalable alternative to lithium-ion batteries with minimal environmental impact.
WHY IT MATTERS
As the global energy transition accelerates, grid stability is becoming a major concern. Solar and wind energy are clean but unpredictable – they don’t always produce power when it’s needed. Eclipse provides a cost-effective, sustainable solution to store excess energy and release it during peak demand, helping reduce reliance on fossil-fuel-based backup systems and making renewables a more viable backbone for the grid. The system is modular and non-toxic, making it especially suitable for decentralized, urban, or industrial deployment.
THE INVESTMENT
Eclipse has just secured €5.5 million in seed funding from Wind, Kima Ventures and Agoranov. The investment will help the company move from proof-of-concept to industrial prototyping. According to Wind Founding Partner, Thierry Vandewalle, Eclipse’s solution is “one of the most elegant and credible alternatives to lithium-based storage” and one poised to deliver critical impact in the short term.
NEXT STEPS
With its funding round now closed, Eclipse plans to accelerate hiring, scale R&D, and begin field deployment of its pilot units. The company is currently in discussions with several industrial and energy sector players to validate and test its system in real-world conditions. Looking ahead, Eclipse aims to position itself as a cornerstone in Europe’s push for energy sovereignty and net-zero targets.
