The project

In 2030 and beyond, multiple energy carriers (electricity, gas, heat, green molecules) will play a role in an interconnected energy system. Increased electrification will support sector integration between end user segments. To benefit maximally from the advantages of sector coupling, a fundamental rethinking of market design, business models and financing models is needed. ReInvent will define a roadmap for sector coupling in Belgium based on advanced modelling and robust test cases.

Project Approach

The ReInvent approach is built on four key pillars, combining conceptual analysis, advanced modeling, real-world testing, and a comprehensive impact assessment to explore how different energy carriers—such as gas, electricity, heat, and green molecules—can be effectively integrated into Belgium’s energy system.
 

  • Pillar 1: Understanding Energy Carrier Roles

This pillar examines the role of various energy carriers in Belgium’s energy mix, focusing on their impact on infrastructure, market design, and business models across different energy end-users. Through collaboration with industry partners and stakeholders, ReInvent will propose new concepts for integrating supply and demand-side energy sectors. In addition to technical feasibility, the financial aspects—including risk, return, and uncertainty—will also be analyzed.
 

  • Pillar 2: Developing a Multi-Sectoral Simulation Model

ReInvent will create a multi-sectoral modeling and simulation framework to analyze the interactions between different energy carriers over multiple timeframes, market designs, and system scenarios. This model will help identify how sector integration can enhance flexibility, balancing, and system adequacy across Belgium’s energy networks, particularly within the electricity grid.
 

  • Pillar 3: Real-World Test Cases

A series of reference test cases will be selected to validate the models developed in Pillar 2. These real-world applications will generate data to refine the simulations, while the insights from the models will help assess the operational and financial viability of sector integration solutions. The selected test cases will focus on key energy carriers, end-user segments, and technologies that are expected to play a central role in future energy systems but still face significant barriers today.

  • Pillar 4: Impact Assessment & Roadmap for Sector Integration

The final pillar will evaluate the potential large-scale deployment of REINVENT solutions in Belgium, assessing their implications for energy security, system balancing, and overall market stability. The outcome will be a strategic roadmap for improved sector coupling and integration, supporting policymakers, businesses, and energy operators in shaping a more resilient and efficient energy future.
