Green hydrogen is becoming increasingly popular, with academics, institutions, and governments concentrating on its development, efficiency improvement, and cost reduction. The objective of the Ministry of Petroleum, Mines, and Energy is to achieve a 35% proportion of renewable energy in the overall energy composition by the year 2030, followed by a 50% commitment by 2050. This goal will be achieved through the implementation of feed-in tariffs and the integration of independent power generators. The present study focused on the economic feasibility of green hydrogen and its production process utilizing renewable energy resources on the northern coast of Mauritania. The current investigation also explored the wind potential along the northern coast of Mauritania, spanning over 600 km between Nouakchott and Nouadhibou. Wind data from masts, Lidar stations, and satellites at 10 and 80 m heights from 2022 to 2023 were used to assess wind characteristics and evaluate five turbine types for local conditions. A comprehensive techno-economic analysis was carried out at five specific sites, encompassing the measures of levelized cost of electricity (LCOE) and levelized cost of green hydrogen (LCOGH), as well as sensitivity analysis and economic performance indicators. The results showed an annual average wind speed of 7.6 m/s in Nouakchott to 9.8 m/s in Nouadhibou at 80 m. The GOLDWIND 3.0 MW model showed the highest capacity factor of 50.81% due to its low cut-in speed of 2.5 m/s and its rated wind speed of 10.5 to 11 m/s. The NORDEX 4 MW model forecasted an annual production of 21.97 GWh in Nouadhibou and 19.23 GWh in Boulanoir, with the LCOE ranging from USD 5.69 to 6.51 cents/kWh, below the local electricity tariff, and an LCOGH of USD 1.85 to 2.11 US/kg H2. Multiple economic indicators confirmed the feasibility of wind energy and green hydrogen projects in assessed sites. These results boosted the confidence of the techno-economic model, highlighting the resilience of future investments in these sustainable energy infrastructures. Mauritania's north coast has potential for wind energy, aiding green hydrogen production for energy goals. [ABSTRACT FROM AUTHOR]

Routine assessment of health facility capacity to provide abortion and post-abortion care can inform policy and programmes to expand access and improve quality. Since 2018, abortion and/or post-abortion care have been integrated into two WHO health facility assessment tools: the Service Availability and Readiness Assessment and the Harmonised Health Facility Assessment. We discuss lessons learnt through experiences integrating abortion into these standardised tools. Our experiences highlight the feasibility of including abortion in health facility assessments across a range of legal contexts. Factors facilitating the integration of abortion include cross-country collaboration and experience sharing, timely inputs into tool adaptations, clear leadership, close relationships among key stakeholders as in assessment coordination groups, use of locally appropriate terminology to refer to abortion and reference to national policies and guidelines. To facilitate high-quality data collection, we identify considerations around question sequencing in tool design, appropriate terminology and the need to balance the normalisation of abortion with adequate sensitisation and education of data collectors. To facilitate appropriate and consistent analysis, future work must ensure adequate disaggregation of recommended and non-recommended abortion methods, alignment with national guidelines and development of a standardised approach for measuring abortion service readiness. Measurement of abortion service availability and readiness should be a routine practice and a standardised component of health facility assessment tools. Evidence generated by health facility assessments that include abortion monitoring can guide efforts to expand access to timely and effective care and help normalise abortion as a core component of sexual and reproductive healthcare., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.
