Spicing Up Hydrogen Inovation

Discover PEPPER

Hydrogen is a crucial element in decarbonizing industries such as steel, chemicals, and heavy transport. The growing demand for green hydrogen is driving the need for more efficient and scalable production technologies. The EU-funded PEPPER project is developing the next-generation electrolysis technology based on planar proton-conducting ceramic electrolysis cells (PCCELs).

What Makes
PEPPER Innovative?

High Efficiency

PEPPER relies on proton conducting ceramics. Operating at 600°C, PEPPER’s system uses industrial waste heat, reducing electricity consumption by up to 20 % compared to liquid water electrolysis.

More Sustainable

The unique planar compact design improves performance, reduces dependency on rare earth elements, and lowers operational costs.

Built for Scale-up

PEPPER is developing and testing a next-generation electrolysis technology, moving from early research (TRL 2) to a working prototype (TRL 4), helping establish the foundation for future industrial-scale green hydrogen production.

How Does
PEPPER Work?

Material
Innovation:

PEPPER will develop and test new non-noble, high-performance materials for PCCEL cells, reducing dependency on rare and expensive resources.

Electrolysis Stack
Development:

PCCEL cells with the best-performing
materials will be scaled-up and integrated into a planar electrolysis stack demonstrator, designed for high efficiency and scalability.

System
Optimization:

The stack architecture will be fine-tuned to operate under realistic industrial conditions, ensuring durability, stability, and peak performance.

Performance
Validation:

The PEPPER technology will be tested under various operating scenarios, including pressurized conditions, to assess efficiency, lifetime, and reliability.

Techno-Economic
& Environmental
Assessment:

The sustainability, environmental impact, and cost-effectiveness of PEPPER’s technology will be evaluated, paving the way for industrial adoption and commercialization.
