EU Project 2026 - 2029

Grant No: 101250775

THUNDERSTACK@TUNI.FI

ThunderStack is a new European research project focused on advancing technology for green hydrogen production, coordinated by Tampere University.

The project aims to improve the durability, reliability, and energy efficiency of high-temperature solid oxide electrolysis systems (SOEL)

Funded by the European Union's Horizon Europe programme under the Clean Hydrogen Partnership, ThunderStack has a total budget of nearly €4 million and runs from 2026 to 2029.

EU Project 2026 - 2029

WORK PACKAGES

SIX STREAMS.
ONE SYSTEM.

Each work package is led by a consortium partner with specific expertise, running in coordinated phases across the 48-month project timeline.


WP1 (TAU): Conceptual Design and Preliminary Testing (M1-M12) | Tampere University

Design Initial Single Cell Concepts And Test Processing Routes, Focusing on Electrochemical with the Novel AC:DC operation mode

WP2 (DTU): Cell unit Characterisation and modelling (M1-M12)

Aims to study electro migration mechanisms behind cell degradation and recyclability under a sustainability perspective.

WP3 (SOL): Short Stack Concept and Optimisation (M13-M30)


focuses on optimising cells for AC:DC operation and developing the first short stacks with the SOL industrial 80cm2 active area cells.

WP4 (DYN): AC:DC Operation Modes on novel Short Stacks (M13-M30)

evaluates AC:DC operation strategies for short stacks, considering Balance of Plant (BoP) components and modelling relevant conditions

WP5 (TAU): The Future of ThunderStack SOEL Technologies (M31-M46)

aims to validate materials and operation modes at a relevant scale, integrating them with the full system to define BoP configurations and reengineering. EPFL will coordinate fabrication of cells, stacks, and BoP components aligned to final validation site requirements.

WP6 (EPFL): Testing Stacks and BoP Components in Relevant Conditions (M31-M48)

validates and integrates all findings into a proposed future system design, involving life-cycle assessment and engineering optimisations.
