Development and integration of solid oxide fuel cells in green hydrogen-based microgrids (SOFC4GreenGrID)

The SOFC4GreenGrID project is based on the research and industrial development of green energy storage technologies, specifically on solid oxide fuel cells (SOFC) that allow transforming the chemical energy of green hydrogen into electricity. The tasks proposed by SOFC4GreenGrID allow the application of innovative technologies (green hydrogen, SOFC systems) and their efficient integration for the development of a new SOFC system of up to 50 kW for the conversion of green hydrogen into electricity. It will develop in an efficient, ecological, sustainable and highly innovative way that will have a highly positive effect on the competitiveness, efficiency and reduction of the environmental impact of both the companies that form the consortium and a wide variety of productive sectors.

It is a strategic project in cooperation between SMEs that aims to develop a reference project in the sector that defines the bases and application requirements for this type of products. The consortium is made up of one medium-sized company and three small companies with extensive experience to carry out the project activities, and is therefore balanced. The project is led by INGENIERÍA Y DISEÑO ESTRUCTURAL AVANZADO, SL (IDEA), specialized in BIM in industrial, Oil & Gas, Mining, Energy and Architectural sectors; REGENERA LEVANTE, SL (REGENERA), dedicated to the development of integral solutions to increase the energy efficiency of facilities; VODIK GREEN ENERGY S. L (VODIK), a company whose focus is on the hydrogen market and its potential as an energy vector; and finally GREEN GROUPING ENERGÍA S.L. (GGE), whose main activity is renewable energies, hydrogen technologies and fuel cells. In addition, there is the participation of Research Organizations, Technological Centers and Universities, which will be key to reach the degree of innovation proposed in the project. In addition to CENER, the Complutense University of Madrid (UCM), the Institute of Nanoscience and Materials of Aragon-CSIC (INMA-CSIC) and the CEU San Pablo University (CEU) are participating in the project.

E3LAB: Living Lab for the development of sustainable energy technology in buildings: Energy Model for Buildings in Use.

Project scope

E3LAB aims to be the first step for the creation of a LIVING LAB that allows the experimentation of energy technologies in a building in use. For this purpose, a pilot building (the school of architecture of the UNAV) will be sensorized and monitored, in addition to this, photovoltaic production and storage systems will be installed and simulated.

An integrated virtual energy model will be developed to obtain detailed knowledge of the building’s energy behaviour under different conditions of use. To comprehensively model the building it is necessary to develop different energy models (or blocks) of the building. All these blocks separately give partial information and E3LAB will unite them to create a Virtual Energy Model of the building that allows integrated decision making of energy generation and use for the building and prepares it for the new trends of grid connection and energy communities.

Cener role

CENER’s objective will be to convert the building into an active element of the electricity system. To this end, it will develop an energy management system with new functionalities that will allow the optimization of thermal and electrical energy management in the building to maximize the use of renewables (including generation forecasting) and the preparation of the building for connection to the grid.

oPEN Lab – Open innovation living labs for Positive Energy Neighbourhoods

The aim of the oPEN Lab is to identify replicable, commercially viable solution packages enabling the achievement of positive energy neighbourhoods within existing urban contexts that are seamlessly integrated into the local energy system as an active micro-energy hub, and to test these technologies and package as an integrated solution at neighbourhood scale.

Three open innovation living labs in the cities of Genk (BE), Pamplona (ES) and Tartu (EE) will test combinations of different close-to-market ready technologies and services and study their performance as a unique operating system. Focus is on demonstrating innovations in an integrated approach combining sustainable design tailored to the local context, seamless industrial renovation workflows, renewable energy generation combined with energy storage systems, urban service facilities and smart operation, life cycle thinking and circularity, and this across the whole value chain, targeting the whole life cycle of the building and its neighbourhood, in view of scaling up and wide replication. A user driven and participatory approach with the neighbourhood community will be rolled out for a holistic and positive energy vision for the neighbourhood, going beyond citizen awareness raising activities.

Intelligent management system for generation, storage and demand of renewable energy for the electricity market

Project scope

The main objective of the ACADIEMS project is to develop an expert system based on artificial intelligence for intelligent energy management, which coordinates renewable generation resources, storage systems and demand flexibility to offer services in the daily, intraday and utility electricity markets. balance (secondary and tertiary regulation). This will result in benefits for all agents in the value chain of the electricity system, and will allow consumers-prosumers to obtain economic returns derived from the provision of flexibility services.


CENER must develop a system that allows it to operate in the cloud, and that monitors the distributed generation and storage resources in real time, and is in charge of carrying out the automated management of said resources in order to be able to participate in the different electricity markets. available. The first step will consist of moving from a local ‘EMS’ system (HMI) to a global one designed to be operated from the cloud (HMICloud). Starting from the system developed in (1) (HMICloud), incorporate the prediction and management of the balance market. The system developed in (2), which focuses on the generation and storage side, should be made to evolve towards a system that also incorporates demand management, allowing the introduction of data from residential, industrial and municipal consumers.

Advanced Solid Oxide Electrolyzers: System Validation and Integration of New Materials into Marketable Devices

Project scope

The ValidSOEC subproject is framed in the coordinated RESOECOX project that proposes a complementary research between institutions of different character with the objective of generating results of high scientific and technical impact at international level. ValidSOEC aims to contribute substantially to the development of prototypes of stable solid state electrolyzers (SOEC) following two complementary approaches: experimental analysis and the development of a theoretical predictive model. The objective of the subproject is to establish a platform to test and compare new SOEC materials, previously validated at laboratory scale, on a larger scale, leading to their implementation in cells with marketable sizes. This represents the first step towards the development of advanced SOECs based on proprietary materials for an efficient and viable production of renewable hydrogen.

CENER role

To this end the specific activities of CENER will initially include a market analysis of the SOEC technology, including materials, cells and stacks, as a basis on which to propose any innovation at both material and device scale. This section will include experimental validation and comparison of commercial SOEC cells and stacks, focusing mainly on the analysis of the initial performance of the cell and its long-term stability. In parallel, CENER will work in the construction of a theoretical SOEC model at different size and time scales. It should be noted that within the project, there will be an important exchange of information between the experimental and theoretical parts, since the modelling of the SOEC device will be fed with data from the experimental analysis. These new pre-commercial cell prototypes will be electrochemically evaluated and compared with the references obtained with commercial cells, as a prerequisite for future commercialization.
