Targeting: Carbon dioxide (2), Hydrogen (1)
Final drilling section completed, bringing commissioning closer and allowing residual Port of Rotterdam heat to supply roughly 120,000 homes and businesses.
Opened a 32‑km Rotterdam hydrogen pipeline, progressed CO₂ and heat projects, boosted LNG capacity, and saw shifting gas flows with higher power‑sector demand.
Five connected CCS projects (Porthos, Aramis, CO₂next, DRC, DSC) will capture, transport and store CO₂ under the North Sea and link industry across the Netherlands, Belgium and Germany.
Targeted by ~2030: cross-border bidirectional hydrogen connection using repurposed gas pipelines (Zandvliet node) to connect major ports/industrial clusters and enable integrated NW-European trade
The first hydrogen plant connects to the Dutch network, marking progress in decarbonizing industry and expanding the hydrogen infrastructure in northwestern Europe.
Tender opened for 200 km CO2 pipeline, linking Maasvlakte to offshore storage, aiding decarbonization. Further tenders for installation and design to follow. Operational by 2030.
A 20-km CO2 pipeline is laid and entrenched under the North Sea, connecting Rotterdam's port to storage reservoirs over 3 km below the seabed.
D-HUBN is an offshore platform for CO2 distribution, using hybrid energy. It coordinates CO2 transport to storage sites, focusing on safety and efficient operations.
