Abstract

Chemical storage of electric energy is recognised as a potential solution to improve the penetration of renewable energy. The coupling of renewable power production with offshore oil & gas exploitation by converting electricity into synthetic fuels represents an opportunity to valorize renewables in remote areas in an energy transition panorama. The present study aims at a comparison of alternative power-to-gas and power-to-liquid strategies for the conversion of offshore wind power into different chemical energy vectors (hydrogen, synthetic natural gas and methanol), taking advantage of conventional offshore oil & gas infrastructures for energy conversion and synthetic fuel transportation. A set of technical, economic, environmental and profitability performance indicators was defined to allow the comparison. A case study in the North Sea was analysed. The results showed that electrolyzers capacity and offshore-onshore distance play an important role on economic indicators. Sensitivity analysis was carried out to test the robustness of the results.
