“…Green hydrogen application can be an interesting alternative to be used as a storage method for the non-dispatchable renewable energy generated . In this regard, Spain has emerged as one of the leading European Countries in terms of projects promoting green hydrogen production . However, using hydrogen as an energy vector faces some challenges since hydrogen features a low volumetric energy density (4.5 MJ/L for compressed H 2 ) and a low boiling point (−253 °C) .…”

This article investigates the economic and environmental implications of implementing green ammonia production plants in Spain.To this end, one business-as-usual scenario for gray ammonia production was compared with three green ammonia scenarios powered with different renewable energy sources (i.e., solar photovoltaic (PV), wind, and a combination of solar PV and wind). The results illustrated that green ammonia scenarios reduced the environmental impacts in global warming, stratospheric ozone depletion, and fossil resource scarcity when compared with conventional gray ammonia scenario. Conversely, green ammonia implementation increased the environmental impacts in the categories of land use, mineral resource scarcity, freshwater eutrophication, and terrestrial acidification. The techno-economic analysis revealed that the conventional gray ammonia scenario featured lower costs than green ammonia scenarios when considering a moderate natural gas cost. However, green ammonia implementation became the most economically favorable option when the natural gas cost and carbon prices increased. Finally, the results showed that developing efficient ammonia-fueled systems is important to make green ammonia a relevant energy vector when considering the entire supply chain (production/transportation). Overall, the results of this research demonstrate that green ammonia could play an important role in future decarbonization scenarios.

“…6 shows the DC electrical consumption (red, left axis) and efficiency (% of HHV, green, right axis) vs output mass flow for the case of 1 MW electrolyzer. OPEX is assumed to be 3% of CAPEX /yr [7] (50.73 €/kW/year, which, supposing about 6,000 hours of operation per year, it will be about 0.008 €/kW/h of operation), and the cost of stack replacement 30% of CAPEX, being the lifetime for stack replacement 80,000 h of operation. Minimum partial load is 10% and hotstandby consumption 2% [7].…”

“…Regarding the water consumption, cost of water is assumed to be 3.8 €/m 3 and the consumption of water to produce hydrogen is 15 L/kg [7], therefore a cost of 0.057 €/kg of H2 produced will be considered for water consumption, which is almost negligible compared to the typical hydrogen selling prices of several € per kg.…”

In this paper, we use MHOGA software for the evaluation of a hydrogen generation system powered by wind turbines. We study the state of the art of the electrolyzers, obtaining the most important characteristics and costs of PEM electrolyzers. The optimization of a Wind-H2 system is performed, obtaining the best combination of components (wind turbines and electrolyzer) and control strategy for the hydrogen production. We will compare to the Wind-only system (wind farm which injects all the electricity produced to the gird). Two cases have been evaluated regarding the electricity price: Spanish SPOT price of 2019 and of 2021, with an expected increase of 1% annual. The Wind-H2 system can be competitive to the Wind-only system if the hydrogen sale price is 4.8 €/kg for the case of 2019 SPOT prices and 6.7 €/kg for the case of 2021 SPOT prices, considering 1% annual increase in the SPOT prices and 2% for the hydrogen price.

“…Meeting the global energy demand while striving for net-zero goals presents a formidable challenge in today's world. Decarbonizing economic sectors and adopting non-pollutant energy sources are imperative steps toward achieving this objective (Acar & Dincer, 2022;Matute et al, 2022). Notably, a significant portion of CO2 emissions 86% emanates from power generation, transportation, and industrial activities (Ayodele et al, 2012;Jahangiri et al, 2020;Kojima et al, 2023).…”

The aim of the present paper is to estimate the green Hydrogen potential from two sources of renewable energies that are solar and wind. This estimation has been done by using satellite data taken from the Global Solar Atlas (GSA) and Global Wind Atlas (GWA). Data were integrated into a Geographical Information System (GIS) to estimate, first the theoretical electricity from solar and wind by using different models. Then we used a third model to estimate the quantity of hydrogen that can be produced from the two different sources mentioned above. As far as we know this is the first attempt to estimate the green hydrogen potential in Mauritania. The results show that the total annual electricity from solar ranged between 275 and 329 GWh/km 2 /year, with the north of the country having the highest potential, especially in the region of Tiris-Zemour and Adrar, in the other hand the south of the country and across the Senegal River line was the regions with the least potential of solar energy. Concerning wind, the values were between 28 and 108 GWh/km 2 /year with the coastline regions localized in the Nouadhibou-Nouakchott axis having the highest potential. The total values of hydrogen production vary between 5428 to 6272 tons/km 2 /year from solar versus 23 to 620 tons/km 2 /year from the wind.
