A techno-economic assessment evaluates the infrastructure, capacity, and investment required for this transformation, considering the variability of renewable energy and its potential to stabilize the power grid. The findings reveal that transitioning to renewable energy requires substantial infrastructure development, including 657 GW of solar PV across 11,972 km², 54 H2CCGTs (600 MW each), and 491 GW electrolyser capacity, with 78,614 tonnes of hydrogen storage. Alternatively, wind scenarios demand 344 GW of capacity over 37,165 km² and 43,500 tonnes of hydrogen storage. Additionally, integrating helium closed-cycle gas turbines (HeCCGTs) into the energy mix necessitates 130 GW of installed power,The transition to renewable energy poses a critical challenge for oil-exporting country, that aim to reduce their carbon footprint while maintaining economic stability. The problem at the heart of this thesis focuses on the complex balance between decarbonization and the socioeconomic benefits of wealth generation through continued energy exports for countries such as Libya, which are heavily dependent on oil exports. Libya, with its abundant solar and wind energy resources and over 1,900 km of Mediterranean coastline, provides a very good case study for examining how it can transition from oil exports to renewable hydrogen production while maintaining economic and energy security. The thesis proposes innovative approaches that use non-carbon technologies such as solar PV farms,gas turbines
