“…Various studies have extensively explored the feasibility and technoeconomic aspects of green hydrogen production and local storage, specifically focusing on harnessing seawater and wind power (Dokhani et al, 2023), (Adrian, 2022). These investigations highlight the low cost associated with water desalination (Dokhani et al, 2023) and emphasized the economic viability of subsea storage of compressed hydrogen as a means to effectively store surplus wind power (Adrian, 2022).…”

“…Researchers have investigated the feasibility of producing and utilizing green hydrogen on offshore platforms by harnessing available wind power to run an electrolyzer, converting water, readily abundant in offshore fields, into hydrogen (Dokhani et al, 2023), (Riboldi et al, 2020). In (Kumar et al, 2023), the authors offered valuable insights into the symbiotic relationship between the green hydrogen sector and offshore industries.…”

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.

“…The cost of hydrogen production is significantly dependent on sources of energy and production processes. For example, hydrogen produced from natural gas reforming has the lowest cost due to its massive scale as well as cheap raw material [9]. However, this process produces a significant amount of carbon dioxide, which contributes to global warming, whereas water electrolysis does not.…”

Offshore wind power stands out as a promising renewable energy source, offering substantial potential for achieving low carbon emissions and enhancing energy security. Despite its potential, the expansion of offshore wind power faces considerable constraints in offshore power transmission. Hydrogen production derived from offshore wind power emerges as an efficient solution to overcome these limitations and effectively transport energy. This study systematically devises diverse hydrogen energy supply chains tailored to the demands of the transportation and chemical industries, meticulously assessing the levelized cost of hydrogen (LCOH). Our findings reveal that the most cost-efficient means of transporting hydrogen to the mainland is through pipelines, particularly when the baseline distance is 50 km and the baseline electricity price is 0.05 USD/kWh. Notably, delivering hydrogen directly to the port via pipelines for chemical industries proves considerably more economical than distributing it to hydrogen refueling stations, with a minimal cost of 3.6 USD/kg. Additionally, we assessed the levelized cost of hydrogen (LCOH) for supply chains that transmit electricity to ports via submarine cables before hydrogen production and subsequent distribution to chemical plants. In comparison to offshore hydrogen production routes, these routes exhibit higher costs and reduced competitiveness. Finally, a sensitivity analysis was undertaken to scrutinize the impact of delivery distance and electricity prices on LCOH. The outcomes underscore the acute sensitivity of LCOH to power prices, highlighting the potential for substantial reductions in hydrogen prices through concerted efforts to lower electricity costs.
