The transition to green hydrogen offers a critical opportunity for Ghana to achieve its decarbonisation and sustainable energy objectives. However, its widespread adoption faces significant barriers. This study seeks to identify, prioritise, and propose strategies to overcome these barriers through an integrated multicriteria decision-making (MCDM) framework tailored to Ghana's context. The methodology combined a systematic literature review with expert consultations. The CRITIC method was applied to derive objective weights for barriers. Thereafter, four MCDM techniques, namely, TOPSIS, EDAS, MOORA, and COPRAS, were employed to rank strategies. These methods were deliberately selected since each method captures distinct dimensions of decision-making. Integrating multiple techniques enhanced the robustness and reliability of rankings by allowing cross-validation of results. The final rankings were validated using Spearman's correlation and T-statistic, ensuring statistical consistency across methods. The results highlight barriers such as limited international collaboration, inadequate financing options, and public acceptance challenges. Conversely, prioritised strategies include infrastructure development, training local expertise, and implementing financial incentives. These findings emphasise the importance of strategic infrastructure and capacity building investments to unlock Ghana's green hydrogen potential. The study provides actionable insights for policymakers, emphasising the need for clear regulations, robust incentives, and international collaboration. Addressing these barriers can facilitate the adoption of green hydrogen and position Ghana as a leader in sustainable energy innovation. These strategies align with Ghana's energy transition targets and present an opportunity to bolster economic growth and reduce carbon emissions.
