Abot OPTIX

OPTIX (Optimising Positive-Energy Districts through Interoperable Digital Platforms) is an EU CETPartnership project that addresses the challenges of urban energy systems through innovative solutions. OPTIX integrates renewable energy technologies, smart control systems, and cutting-edge digital platforms to create and optimize Positive-Energy Districts (PEDs).

By combining digital twins, blockchain-based energy trading, and AI-driven optimization tools, OPTIX ensures seamless integration of renewable energy sources—such as solar PV, geothermal systems, and thermal storage—to enhance energy flexibility and community participation.
Project overview

Project Objectives

OPTIX aims to transform urban energy systems by fostering Positive-Energy Districts (PEDs) through advanced technological innovation and cross-sectoral collaboration. The project’s main objectives are:

  • Objective 1: Develop and validate innovative technological solutions for integrating solar PV, storage systems, and renewable heating/cooling technologies to enhance energy flexibility and efficiency.
  • Objective 2: Create and test advanced digital twin models and blockchain-based energy trading platforms to enable real-time monitoring, analysis, and secure peer-to-peer energy transactions.
  • Objective 3: Demonstrate the effectiveness of the project’s solutions in seven diverse real-world pilot sites across Europe, showcasing their scalability and adaptability in different contexts.
  • Objective 4: Develop and disseminate a novel, replicable, and scalable model for Positive-Energy Districts, setting a new benchmark for sustainable urban energy systems.
  • Objective 5: Empower local communities and stakeholders by fostering energy awareness, participation, and collaborative decision-making.

Pilot Demonstrations

The OPTIX project will demonstrate its innovative solutions across seven real-world pilot sites, located in diverse European contexts. Each pilot site addresses unique challenges and opportunities, contributing to the project's overarching goal of optimizing Positive-Energy Districts (PEDs).

  • Case 1: P2P Energy Trading (Limerick, Ireland) Demonstrating peer-to-peer energy trading in a mixed-use urban district at Limerick Docklands. Renewable energy systems, including solar PV and battery storage, will be integrated to foster an energy community with optimized performance and reduced carbon footprint.
  • Case 2: Grid Balancing (Västerås and Stockholm, Sweden) Testing smart HVAC systems and energy storage for thermal and electrical grid balancing. Leveraging model-based and data-driven algorithms, the pilot will align with Svenska Kraftnät’s guidelines for grid integration.
  • Case 3: Municipality-Based Energy Opportunities (Lyngby-Taarbæk, Denmark) Exploring large-scale solar PV installations on municipal buildings, optimizing energy systems with smart grid technologies, and addressing heating and cooling demands through integrated solutions.
  • Case 4: Positive-Energy Building (Turkey) Demonstrating solar-assisted heat pump systems integrated with PV/T panels. Using digital twins, the pilot will simulate and optimize renewable energy performance while evaluating market and environmental impacts.
  • Case 5: Power-to-Heat in District Heating Networks (Germany) Investigating renewable energy integration into district heating networks, supported by heat pumps and solar thermal systems. The pilot will optimize heating demands and renewable energy utilization for multistorey buildings.
  • Case 6: Renewable Energy Optimization for SOHOs (Graz, Austria) Aiming for 100% renewable energy self-consumption, the pilot will implement smart control of heat pumps, PV systems, and electric vehicles in historic buildings with compact floor areas.
  • Case 7: Digital Twin of Fuel Cell Systems (Turkey and Romania) Developing a digital twin of a 2 kW fuel cell module to optimize hydrogen energy systems. The pilot will analyze performance degradation, maintenance planning, and real-time data management for energy systems.

These pilot sites will validate the technical, economic, and social viability of OPTIX solutions, ensuring scalability and replicability across different urban contexts.
