DELYCIOUS - Diagnostic tools for ELectrolYsers: Cost-efficient, Innovative, Open, Universal and Safe
A Horizon Europe and Clean Hydrogen Partnership funded R&D project aimed at developing advanced diagnostic and monitoring tools for water electrolysers that are cost-efficient, innovative, open, universal and safe.
Renewable Hydrogen:
A Strategic Pillar for Europe’s Net-Zero Goals
The Net Zero Industry Act highlights green hydrogen as essential for Europe’s clean energy future, with hydrogen expected to meet 20% of the EU’s energy needs by 2050.
Powered by renewable energy, water electrolysis produces clean, carbon-neutral hydrogen – an energy carrier that can be stored, transported, and converted back to electricity with water as the only by-product.
Electrolysis is Key to Producing Low-Carbon Hydrogen
The three main types are:
AEL
Alkaline Water
Electrolysis
PEMEL
Proton Exchange Membrane Electrolysis
SOEL
Solid Oxide Electrolysis
Common Challenges
Unlocking the potential of water electrolysers

Stack Durability
Extending the lifespan of electrolyzer stacks.

Energy Reliability
Maintaining performance with variable energy inputs.

Operational Optimization
Developing real-time monitoring tools to fine-tune operation and reduce degradation.

Cost Efficiency
Lowering the overall system and ownership costs.

Advanced Diagnostics
Combining Electrochemical Impedance and Raman Spectroscopy with both physical and data-driven modeling to monitor and predict system state of health.

Universal Compatibility
Validated solutions for AEL, PEMEL and SOEL, across both low and high temperature operational regimes.

Collaborative Expertise
A robust European consortium blending research, technology development, and market leaders in electrolyser deployment.
