Project description
Multi-energy storage for a flexible renewable grid
The expansion of variable renewable energy is creating challenges for energy systems, particularly in storing excess power, providing heating and cooling, and maintaining grid stability. Supported by the Marie Skłodowska-Curie Actions programme, the FLEXPTES project is developing a multi-optional power-to-heat-to-power energy storage system that operates across four temperature levels. This enables the simultaneous delivery of electricity, heat, cold and grid stability services. The project will also design and model the system dynamics, validate components through scaled testing and build fast surrogate models to capture performance efficiently. These will be integrated into an AI-based control framework to enable real-time operation. Overall, FLEXPTES paves the way for flexible renewable energy systems in line with Europe’s transition to clean energy.
Objective
Phasing out fossil fuels while integrating massive shares of variable renewable energy (VRE) has created urgent challenges: how to store energy at scale, provide heating and cooling, and keep the grid stable. Power-to-Heat-to-Power systems (PTES) stand out as the only single technology that can address all these needs. Yet today’s PTES concepts are limited: confined to two temperature levels and struggling with inefficient dynamics that hinder real-world deployment.FLEXPTES breaks this barrier, proposing a novel multi-optional PTES architecture operating across four temperature levels, unlocking new thermodynamic pathways for simultaneous delivery of electricity, heat, cold, and grid stability services. The system will be designed, dynamically modelled, and validated through scaled component testing. From this foundation, fast, modular surrogate models will be built to capture system dynamics. These surrogates will then power a cutting-edge AI framework, combining predictive control with reinforcement learning for real-time, efficient, and flexible dispatch.
The outcome is a storage technology capable of delivering electricity, heat, cold, and grid stability simultaneously with high efficiency, unprecedented response time, and low computational overhead. Beyond direct operation, FLEXPTES will have a transformative impact on long-duration storage, enabling day-to-day multi-energy services in renewable markets, while also revolutionizing future dispatch planning and storage expansion modelling through AI integration. In doing so, the project directly supports the sustainability goals of clean and affordable energy while contributing to advancement in energy infrastructure and supporting climate action.
