Horizon Europe Closed Research and Innovation Action

Novel solutions for off-grid storage of renewable energy for critical infrastructures

HORIZON-CL5-2026-03-D3-21

Description

Expected Outcome:

Project results are expected to contribute to all the following expected outcomes:

  • Enhanced European knowledge and leadership in off-grid clean energy storage technologies.
  • Improved energy security and cost-effectiveness of Europe’s energy systems, particularly for critical infrastructure.
  • Elimination of fossil-based backup solutions for critical infrastructures, strengthening European competitiveness.

Scope:

The topic aims to develop novel, cost-efficient off-grid energy storage solutions for renewable energy, tailored for critical infrastructures such as hospitals, transport hubs, data centres, and utilities. Solutions should address challenges specific to off-grid or non-interconnected area contexts, including storage scale, compromised grid interaction, resilience to potential shortages of critical materials, and multi-energy needs (electricity, heating, cooling). Emphasis should be on robustness and error-freeness, while considering sustainability, efficiency and performance. The project should foresee these solutions for using real-world critical infrastructures through simulation and experiments and establishing a procedure for decision-making, focusing on energy security and resilience against high-impact, low-probability events, by ensuring operational efficiency both on-grid and off-grid. Where relevant, interdependencies among critical infrastructures and system redundancy should be considered.

Projects are encouraged to support the reconstruction of Ukraine by including Ukrainian beneficiaries.
