The GRAVITEQA and EnergyGuard projects, coordinated by the National and Kapodistrian University of Athens, aim to revolutionize the energy sector through AI-based solutions. GRAVITEQA, launched to address grid reliability challenges in the context of the EU's 2030 climate goals, focuses on combining gravitational storage, quantum computing, and AI-driven analytics. The project plans to repurpose abandoned coal plants and mines for energy storage, optimize electric vehicle charging, and enhance grid flexibility. EnergyGuard, the parallel project, aims to establish a testing facility for trustworthy AI products in the energy market. It integrates various European large-scale testing facilities covering elements like hydrogen testing platforms, renewable energy communities, and digital twins of energy networks. These facilities will be accessible to end-users to validate products and assess cybersecurity risks. Both projects have a positive sentiment towards promoting renewable energy, innovation, and eco-friendly energy systems for the future.
