eGHOST will be the first milestone for the development of eco-design criteria in the European hydrogen sector. Two guidelines for specific FCH products (PEMFC stack and SOE) will be completed and the lessons learnt will be integrated in the eGHOST White Book, a reference guidance book for any future eco-design project of FCH systems. eGHOST aims to support the whole FCH sector. Therefore, it addresses the eco-(re)design of mature products (PEMFC stack) and those emerging with TRLs around 5 (SOE) in such a way that sustainable design criteria can be incorporated since the earliest stages of the product development. eGHOST will go a step beyond the current state of the art of eco-design by incorporating eco-efficiency assessment, i.e. combining environmental and economic decision-making tools, and social life cycle assessment to determine the social impacts of the products. Therefore, eGHOST proposes a sustainable (re)design looking at minimizing the economic, environmental and social impacts of the products along their life cycle. Other innovation will be the use of prospective approach for the life cycle thinking tools used to assess the products performance, i.e. to determine the impacts of all the life cycle stages of the product at the time of its occurence. This is required to get valid information of those products at early stages of development. The European Commission considers eco-design as a key factor to fulfil its commitment to a climate-neutral and circular economy in 2050 as identified in different documents (EU Green Deal, New Industrial Strategy for Europe, Circular Economy Directive…). eGHOST will contribute to positioning FCH in this context by developing the first preparatory study of a hydrogen product under the guiding principles of the Eco-design Directive. As well, eGHOST will improve the understanding of FCH technologies as a sustainable investment under the EU Taxonomy, and will enhance Corporate Social Responsibility studies.

The project BIOGASMENA follows an innovative, integrated and multi-disciplinary approach for the development of biogas technology and know-how in the ERA and the MENA region, combining technology transfer and laboratory research with academic exchanges, communication and training activities directed to both the general public, especially small farmers from the MENA region, and the academic community, with a particular focus on young researchers. The project includes the following tasks: (1) building dry fermentation biogas plant at pilot scale, (2) building a hybrid energy system at pilot scale, combining biogas, solar and wind energies for autonomous electricity supply, (3) equipping biogas laboratories in Algeria and Tunisia, (4) investigating biogas production in the MENA region, in particular via dry fermentation in lab-scale and bench-scale experiments, (5) including results into an online database for modeling of bioconversion kinetics, (6) optimizing digestate treatment, characterization and utilization, (7) investigating the combination of biogas production with microalgae cultivation, (8) LCA and techno-economic analyzes of designs for biogas production in the MENA region, (9) training young researchers from the MENA region in EU, in particular by following CIHEAM courses (10) informing of the research community, farmers, and the general public about biogas technology. A small-scale pilot plant of 5m3, with a planned electrical power of 500W will be built in Tunisia with concerted efforts from the partners. A thermal solar heating system will be implemented to maintain the temperature of the reactors. The biogas plant will be integrated into a hybrid system with solar photovoltaic and wind energy for grid-independent (island) electricity production, and serve as a demonstration platform for future research in the MENA region. Research laboratories in the MENA region will be equipped. In Tunisia as well, dry fermentation reactors will be built at the laboratory and coupled with a module for dewatering and ultrafiltration, which will be connected to microalgae cultures. In Algeria, a highly efficient, patented methane potential assay developed previously at the University of Hohenheim, will be installed. In the MENA region and EU, concerted research efforts will be carried out to optimize the biogas process, in particular with dry fermentation, focusing on temperature level, structure of the feedstocks, nutrient balance, as well as trace metals supply and supplementation. The quality and maturity of digestates from dry fermentation will be analyzed, and tested for plant growth in pot experiments. Furthermore, innovative digestate treatment methods will be tested, including a system for ammonia recovery during drying of digestate, and the cultivation of saline microalgae and mixotrophic microalgae fed with the liquid fraction of digestate. Young Researchers from the MENA region will move to EU to work on practical topics of the project. Promising young students will be sent to CIHEAM-IAMB in Bari to follow the International Master course in Land and Water Engineering, with second-year secondments on the project. Finally, experiences of rural communities in Egypt with household biogas production based on Indian-type digesters will be analyzed, and the techno-economic potential for the implementation of dry fermentation for electricity production will be studied.

The aim of SUNRISE is to make sustainable fuels and commodity chemicals at affordable costs of materials and Earth surface, using sunlight as the only energy source. This includes nitrogen fixation and the conversion of atmospheric CO2 into products, which will be a game changer in the fight against climate change. The CSA SUNRISE gathers the scientific and industrial communities that will develop radically new technologies to harvest solar energy and enable the foundation of a global circular economy. SUNRISE targets three synergistic S&T approaches: (i) electrochemical conversion with renewable power, direct conversion via (ii) photoelectrochemical and (iii) biological and biohybrid systems. These will be implemented with the crucial support of novel material design via high performance computing, advanced biomimicry, and synthetic biology. Ultimately, the novel solar-to-chemical technologies will be integrated into the global industrial system. In 10 years, SUNRISE will bring renewable fuel production to TRL 9 at a cost of 0.4 €/L and atmospheric CO2 photoconversion at TRL 7. The ambition is to convert up to 2500 tons of CO2 and produce > 100 tons of commodity chemicals (per ha per year), realizing a 300% energy gain over present best practices and deploying devices on the 1000 ha scale. This requires new solutions for absorbing >90% of light and storing >80% of the photogenerated electrons in fuels/chemicals produced in large-scale solar energy converters, in close interaction with social and environmental sciences to optimize their deployment. SUNRISE will make Europe the leading hub of disruptive technologies, closing the carbon cycle and providing a solar dimension to the chemical industry, with enormous economical, societal and environmental benefits. SUNRISE is an intrinsically flagship enterprise that has obtained explicit commitment from top organisations, both from industry and academia across Europe, to set the stage for the next steps of the action.
