There is urgent need in the UK to reduce the carbon emissions of offshore assets on the UK continental self. Many initiatives have been proposed over the past decade for electrification of these assets in order to shift towards net-zero platforms1. Offshore wind energy, as a mature technology, exists strongly in most of these initiatives despite the high variability of its output power, which has a direct impact on the sizing of the short-duration battery storage and the percentage of renewables penetration. This paper investigates the impact of co-locating the promising and complementary wave energy with offshore wind energy to create islanded micro-grids to electrify North Sea Oil and Gas assets. The aim is to study the impact of this renewable mix on short-duration battery storage sizing. Two operational scenarios: wind-only and wind/wave are investigated at different locations in the North Sea, and two software (SAM and HOMER) are used for the power calculations considering renewable penetration below 50%. Battery storage sizing is performed based on the worst-case scenario of renewable power loss; this is compared for both wind-only and wind/wave scenarios. The results suggest that, the wind/wave scenario yields a smoother power output compared to the wind-only scenario, hence the size of the required short-duration battery storage is reduced by 33-50% compared to wind-only scenario at all locations. Moreover, the economic study undertaken alongside shows promising figures whereby overall levelized cost of energy increases only marginally, by 4-9%, with the addition of wave energy. All studies are carried out based on Vestas's V164-9.5 wind turbine and Mocean Energy's Blue Horizon 250 wave energy converter.
