We clarify the definitions of institutions and derive a definition ap plicable to the institutional framework in this study's context. Through an extensive analysis of the literature, employing grounded theory for a structured literature review, we present an empirical and theoretical literature review on the topic. We have identified corruption, political instability, bureaucratic red tape, investment risks such as macroeconomic stability, and a lack of infrastructure and technology as the main challenges within the Ivorian institutional framework. These findings wer e further validated through seven interviews with energy stakeholders from Côte d'Ivoire. Our literature reviews indicate that Côte d'Ivoire possesses the potential for such a project. However, challenges persist within the institutional framework. While the government has initiated efforts to address these issues, experts remain skeptical abou t the project's feasibility. Concerns are raised due to the maturity of green hydrogen production technology and the absence of clear policies and regulations favoring renewable energy, especially in terms of feed in tariffs, tax incentives, production tar gets, and support mechanisms for renewable energy initiatives. Additionally, skepticism surrounds the government's ability to combat corruption effectively. This thesis underscores the pivotal role of the institutional framework's quality in green hydrogen project implementation within the region. To improve it , we propose measures such as creating regional markets, digitalizing systems, staff training, establishing an independent regulatory agency, and fostering public private partnerships.

The production of green hydrogen is hindered by either the availability of renewable energy resources or water. Usually places with high renewable energy potential have limited availability of water as seen in arid or semi-arid regions. Nevertheless, green hydrogen needs to be produced from renewable energy and water. To solve the problem, we introduce the direct-air-capture power to gas (DAC-PtG) technology, which uses a carbon dioxide recovery method, direct-air-capture (DAC) coupled with a polymer-exchange membrane (PEM) electrolyser to produce green hydrogen using renewable energy resource. DAC units are designed to capture carbon dioxide from the atmosphere, they are not point capture systems and can be installed in places different from where the CO₂ is being emitted. The DAC unit co-adsorbs water in the process of capturing CO₂ from the atmosphere, which is then fed into the PEM electrolyser for hydrogen production. The study highlights CO₂ output, electrolyser cost, the weighted average cost of capital, and the efficiency of the electrolyser as economic risk factors. Drivers of environmental impacts are also identified as, source of energy used, type of adsorbent material used for the DAC unit, the DAC plant material used for construction (if recycled plant material is used for construction the environmental footprint of the DAC unit reduces), and the type of electrolyser used. This paper proposes a project management strategy to manage both environmental and economic risks and uncertainties through technology complementarity, electrolyser cost savings methods, green purchasing techniques, identifying a project location with a strong legal framework, and studying the relationship between CO₂ captured, water adsorbed and relative humidity. The findings of this study can be used as a stepping stone to further research especially for the environmental impacts of the DAC-PtG technology. Most importantly, this study can be used as a theoretical reference when setting up DAC-PtG projects.

West African countries seem to be a solution to unlock a part of the energy shortage with its potential in green hydrogen estimated at up to 165,000 terawatt-hours per year by using wind and solar energy, of which 120,000 terawatt-hours could be produced for 2.50 euros per kilogram (Edgar, 2021). For West Africa to take advantage of its hydrogen potential and avoid the most predominated risks related to technology, environment, economy, and social aspects, a review of challenges and opportunities in the supply chain for green hydrogen production in West Africa could be an important step in shaping the future hydrogen business in that particular region. three countries are selected as case studies based on a review of their characteristics such as geography, political stability, support for renewable energy and green hydrogen development, and green hydrogen production potential, among others. A series of criteria are defined and assessed to understand and evaluate the current status of the supply chain for green hydrogen in West Africa based on a comparative methodology. This thesis provides an overview of strategies to address the challenges and opportunities for green hydrogen production in West Africa.

The electricity source for the facility is solar photovoltaic (PV) systems, while concentrated solar power (CSP) is harnessed to provide heat. Additionally, the water necessary for the electrolysis process is sourced from Direct Air Capture (DAC). A keen attention is paid to the DAC component to understand the operating principles and interplay with other components. The research is conducted in Senegal, focusing on specific subcases located in Saint-Louis, Touba, Tambacounda, Kolda, and Ziguinchor. Each of these locations represents the different climatic zones of Senegal. The primary aim is to identify the best weather conditions for a competitive stand-alone system and to determine the cost drivers of such a system. The data used are secondary data extracted from the literature and official websites. We perform calculations through a Python-based algorithm to determine the economical parameters of each case and then determine the optimum scenario. We determine the annualised cost and the levelized cost of the different commodity using weather data from the year 2019. Hydrogen can be produced in Senegal at a levelized cost ranging from 6.88-7,57 €/kgH2 and a carbon dioxide capture cost ranging from 6,88 to 7,57 €/kgH2. the conclusion of this study is that humid regions with good potential for renewable energy are favourable to such a system. The cost of heat acts as a primary cost driver.
