Through 24_7 ZEN project, an ecosystem that can be efficiently scaled and replicated to multi-MW scale installations will be developed and validated, and further knowledge on how to improve the performance of rSOC and make them more cost competitive will be generated.


At the end of the project, new and viable scenarios to provide grid balancing and supply green hydrogen will be presented by means of a deep-techno economic analysis.




This WP the requirements for the rSOC components, stack and system, as well as the integration of the developed system to both electricity and gas grid, to create the rSOC ecosystem will be thoroughly analysed and assessed to ensure the success of the project and provide feedback to all the WPs.
The economic and regulatory framework have a paramount effect on the technical definitions and the potential economic revenues of a smart electric system relying on RES, energy storage conversion and specifically Power-to-H2-to-Power in the form of rSOC.


Development of enhanced SOC components for optimized reversible operation

This WP deals with R&D on innovative solutions to achieve the KPI of current density and durability rate targeted by the efficient operation of the rSOC system and stated on the call (1.5 A/cm2 in SOFC and SOEC modes and 0.4%/kh).

This will require R&D on materials and surface engineering to achieve an improvement of all the components present on the SoA SOC stacks (electrodes, barrier layer and interconnects). Automatised deposition techniques and other innovative manufacturing technologies (Inkjet printing, Pulsed Laser deposition, Rapid Thermal Annealing, Electrophoresis, etc.) will ensure the high quality, high reliability and scalability of the different components, whilst improving their microstructures and features.


rSOC system development

WP3 will deal with the design, manufacturing and qualification of a reversible solid oxide cell system of 33/100 kW scale. The system will be able to produce power from natural gas, hydrogen-blended NG and hydrogen. It will also operate in steam electrolysis to produce hydrogen.


Integration of the gas, rSOC, Control and EMS modules as a system

WP4 will deal with all design, manufacturing and commissioning activities related to the integration of the rSOC system with its required auxiliary systems in a containerized prototype, which will be integrated with the different energy grids (electrical grid and natural gas grid).
The WP will be focused on the development of the main auxiliaty systems (power module, the NG conditioning system, the water treatment system, the H2 conditioning system, the steam generation & heat management system, methanation system)


Integrated Power Balancing Plant and operation (Demo)

WP5 refers to the PtG/GtP rSOC system, applied and demonstrated at CERTH’s premises in diverse context scenarios defined in WP1. The WP covers: (a) site design of the plant and will include site layout, safety assessment, detailed design and drawings of the overall installation, together with all the permitting process; (b) site preparation, civil works, construction, installation and commissioning of the various equipment to be demonstrated; (c) on-site training; (d) report of the day to-day operation and maintenance of the pilot.


Dissemination, Communication and Exploitation activities

This WP will deal with communication, dissemination and exploitation of the main activities and outcome of 24_7 ZEN to maximise the project’s visibility by reaching the key audience and target groups defined in the project, support engagement of stakeholders groups, raise project awareness, and promote the activities, tools and outcomes of the project. This WP will also access the technology and economic feasibility of the solution, generation outcomes that will be fed into the exploitation plan.


Project management and coordination

WP7 encompass the financial, administrative and contractual components including the risk monitoring and mitigation during Project. Clear management structures and techniques are in place to build the framework for effortless implementation of the project goals. WP1 is led and implemented by IREC.
All partners are involved in the execution of the tasks. IREC will act as a direct contact with the EC. The rest of the partners are involved in the management through the WP and working groups.
