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.

DELYCIOUS’s Innovative Approach

Combining Electrochemical Impedance and Raman Spectroscopy with both physical and data-driven modeling to monitor and predict system state of health.
Validated solutions for AEL, PEMEL and SOEL, across both low and high temperature operational regimes.
A robust European consortium blending research, technology development, and market leaders in electrolyser deployment.
