Deepdive 2025 Scenarios

In 2025, PATHS2050 outlined pathways for Belgium’s energy system on the road to net-zero by 2050. In 2026, this work was further developed through a series of deep dives that test how sensitive key outcomes are to pivotal choices and constraints, across technology, infrastructure, costs and policy conditions.

Together, the four deep dives provide a more granular view on the robustness of Belgium’s net‑zero pathways: offshore wind deployment, the role of clean molecules, the contribution of Carbon Capture and Storage (CCS), and the implications of moving towards a CO₂ near‑zero energy system.

  • The offshore wind deep dive examines how delays in offshore wind deployment would ripple through the electricity system and the wider energy system, affecting emissions, costs and import dependence.

  • The molecules deep dive clarifies the role of molecules across the PATHS2050 scenarios and how they interact with electrification and imports. 

  • The CCS deep dive explores how Carbon Capture and Storage could support Belgium’s hard-to-abate industries on the path to climate neutrality. 

  • The CO₂ near-zero deep dive examines what moving closer to near-zero emissions changes in terms of costs and system choices.

All four deep dives are now available on the PATHS2050 website, offering complementary insights into key trade-offs, system costs and strategic choices on Belgium’s path to climate neutrality.
