Electrification of the road transport sector will likely include both battery-electric (BEV) and hydrogen fuel cell electric vehicles (FCEV). Sector coupling of energy carriers has been described as a route forward for efficient integration of renewable energy. The objective of this work was to determine the net present cost improvements with co-localization of charging and filling stations, i.e. sector coupling of electricity and hydrogen energy carriers, and how this would impact optimal sizing of the PV production and battery storage. A grid-connected co-localized charging/filling station situated north of Oslo, Norway, was modeled in Homer Pro and Homer Grid. PV energy generation profiles were modeled using PVsyst and a snow loss model. Demand data for BEV and FCEV was synthesized based on historical traffic data (year 2015-2019). The results show that the electrification of the road transport sector passing the point of selection requires about 53 MW peak electricity demand. Co-localization, i.e., sector coupling of BEV and FCEV, indicated a marginal cost-efficiency improvement of 0.4-1.1% and increased optimal PV capacity and reduced PV-power export.
