New ENTSO-E Report: The Impact of Renewable Hydrogen on the Power System

This comprehensive report offers valuable insights into the growing hydrogen market and its interdependence with the electricity system.

✅ Key Takeaways:

📌 System Integration is Key
Electrolysers and hydrogen facilities should be strategically planned, located, and operated in coordination with the power system to maximise system benefits and consumer value.

📌 Location Matters
Whether near renewable energy sources, hydrogen demand centers, or both — the siting and grid connection (on-grid/off-grid) of electrolysers are crucial for infrastructure optimisation, especially as natural gas is phased out.

📌 Smart Regulation & Market Design
Policies defining renewable hydrogen must consider not just the hydrogen sector, but also incentivise investments that support the power system and accelerate decarbonisation.

📌 Flexibility Potential
Electrolysers could provide valuable short-duration flexibility via implicit and explicit demand response, especially as the market matures.

📌 Contributing to Resource Adequacy
Power-to-Hydrogen (P2H2) supports the grid through demand response. Hydrogen-to-Power (H2P) can offer carbon-neutral backup via repurposed gas turbines and capacity mechanisms.

📌 Certification Trade-offs
Hydrogen regulation (e.g., GOs and RFNBO criteria) must find a balance between strict decarbonisation goals and power system needs. To strike a balance, GOs and RFNBO requirements should be designed with flexibility in mind.
