Six pioneering projects funded by the Clean Hydrogen Partnership are driving innovation across the hydrogen value chain. From automated and 3D-printed solid oxide cells (AMPS, HyP3D) to modular reactors using ammonia as a hydrogen carrier (SINGLE), these breakthroughs enhance efficiency and scalability. New safety and monitoring solutions (ELVHYS, OPTHYCS) improve hydrogen handling and leak detection, while FLEX4H2 enables low-emission combustion of hydrogen and gas blends.
Together, they showcase Europe’s leadership in advancing clean hydrogen technologies.
Automating SOC Stack Manufacturing for High-Precision Hydrogen TechnologiesProject: AMPS
Partners leading the innovation: Elcogen Oy
The AMPS project is advancing the industrialisation of solid oxide cell (SOC) production through automation of key manufacturing steps. It introduces a fully automated jig for laser welding interconnect plates, ensuring precise alignment and quality control, and an automated handling system for fragile SOC stack components such as gaskets, interconnects, and cells.
3D-Printed High-Performance SOCs for High-Pressure Hydrogen ProductionProject: HyP3D
Partners leading the innovation: Fundacio Institut de Recerca en Energia de Catalunya, H2B2 Electrolysis Technologies SL
The HyP3D project pioneers the use of 3D printing to create solid oxide electrolysis cells (SOCs) with corrugated yttria-stabilised zirconia electrolytes that boost the active area by up to 60% and enhance resistance to pressure imbalances. Featuring embedded gas channels, inlets, outlets, and sealing features, these innovative cells enable simpler, lighter stack designs using flat metallic interconnects.
Modular Stack Design for Ammonia Dehydrogenation & Hydrogen ProductionProject: SINGLE
Partners leading the innovation: CoorsTek Membrane Sciences AS
The SINGLE project will enable ammonia as an energy carrier in the hydrogen value chain through demonstration of a Proton Ceramic Electrochemical Reactor (PCER) that integrates the ammonia dehydrogenation (ADH) reaction, hydrogen separation, heat management and compression in a SINGLE stage It introduces an advanced modular stack and reactor design for proton ceramic electrochemical reactors (PCERs) that enhances efficiency, scalability, and heat integration. Through innovative sealing, interconnect, and stack technologies, the system optimises gas flow, thermal management, and electrical connections while minimising temperature gradients.
Innovative Safety Solutions for Cryogenic Hydrogen Transfer in Mobile ApplicationsProject: ELVHYS
Partners leading the innovation: Norges Teknisk-Naturvitenskapelige Universitet - NTNU, German Airspace Center, Air Liquide SA
The ELVHYS project is developing cutting-edge safety strategies for cryogenic hydrogen transfer systems used in mobile applications. Combining experimental, theoretical, and numerical approaches, it analyses hydrogen transfer procedures and potential loss-of-containment scenarios to identify effective safety barriers and hazard zoning strategies.
AI-Enhanced Software for Advanced H2 Leak Detection and System MonitoringProject: OPTHYCS
Partners leading the innovation: FEBUS Optics
The OPTHYCS project is developing an integrated software solution for hydrogen leak sensing using advanced fibre optic technologies. A new FrontEnd platform, powered by machine learning algorithms, will enable intelligent data processing, optimised visualisation, and clearer communication with end users, thereby enhancing the safety, efficiency, and reliability of hydrogen systems.

Flexible Sequential Combustion System for Low-Emission Hydrogen and Gas BlendsProject: FLEX4H2
Partners leading the innovation: Ansaldo Energia SpA
The FLEX4H2 project advances sequential hydrogen combustion technology in gas turbines to enable low-emission operation across the full range of hydrogen–natural gas blends, up to 100% pure hydrogen combustion. Its innovative design combines a new injection scheme, advanced cooling, and thermoacoustic control devices to ensure stable, efficient combustion. The high potential of this innovation was confirmed at the workshop on hydrogen combustion organised in Japan by the Clean Hydrogen JU and NEDO (New Energy and Industrial Technology Development Organisation), where it received high level of attention by all participants.
