Bridging the Gap – How HAVEN Tackles the Limits of Today’s Battery Systems
Battery Energy Storage Systems (BESS) are among the most widely deployed solutions for grid flexibility and renewable integration. Yet, they face a fundamental challenge: no single battery technology can meet both the energy and power density demands required by the evolving energy landscape.
Most BESS either focus on storing large amounts of energy over time (HE) or delivering rapid bursts of power (HP). To provide full value to the grid, especially in high-RES environments, storage systems need to do both. This is where Hybrid Energy Storage Systems (HESS) come into play.
The HAVEN project is at the forefront of this innovation, developing a next-generation HESS that bridges this technological gap. By combining multiple storage technologies, including supercapacitors, lithium-ion chemistries, and other emerging solutions, HAVEN will deliver:
🔹 Enhanced braking energy recuperation
🔹 Greater operational flexibility
🔹 Improved lifespan and reduced degradation
🔹 A lower overall system weight and cost
But HAVEN doesn’t stop there. The complexity of HESS systems requires a new approach to energy management. That’s why the project integrates advanced control systems and a Digital Twin, capable of adapting to different battery chemistries, use cases, and lifecycle stages.
Whether it’s supporting renewable energy integration, grid balancing, or EV charging hubs, HAVEN is creating a solution that meets the real-world needs of Europe’s evolving power infrastructure, efficiently, intelligently, and sustainably.
