Happy World Science Day from the PEPPER team

Published: 10. November 2026

On 10 November, the PEPPER team wishes everyone a happy World Science Day. We are using the day to share, in a few words, what we are working on: a way to make clean hydrogen with less electricity.

Our mission
PEPPER is developing planar proton-conducting ceramic electrolysis cells. These cells split steam into hydrogen and oxygen at 600 °C and below. This offers opportunities for an easy integration into industrial processes realeasing waste heat, and to use more conventional and relatively cheaper material compared to mainstream high temperature technologies. The aim is to produce cost effective hydrogen and decarbonise industrial processes.

By its end, the project aims to develop cells of around 100 cm², integrate them into short stacks and advance the technology from TRL 2 to TRL 4 through laboratory validation, paving the way for future scale-up and demonstration.

Science for society
UNESCO celebrates this day as the World Science Day for Peace and Development. It reminds us that research matters most when it is shared and put to use. In PEPPER, research centres, universities and companies from Germany, France, Denmark, Austria, Estonia and Czechia work towards one goal, and we will keep sharing what we learn along the way.
