Fuel Cell Electric Vehicle-to-Grid Feasibility: A Technical Analysis of Aggregated Units Offering Frequency Reserves

Abstract

Fuel Cell Electric Vehicles (FCEVs) in combination with green hydrogen (obtained from renewable sources), could make a significant contribution in decarbonizing the European transport sector, and thus help achieve the ambitious climate goals. However, most vehicles are parked for about 95% of their life time. This work proposes the more efficient use of these vehicles by providing vehicle-to-grid (V2G) services achieving the integration of the transport and energy systems. The aim of this work is to determine the technical and financial potential value that FCEVs could have by providing frequency reserves. Experiments were carried out with a Hyundai ix35 FCEV that was adapted with a power output socket so it can operate in V2G when parked, delivering maximum 10 kW direct current power. Results show that both power sources in the fuel cell electric vehicle, which are the fuel cell stack and the battery, can react in the order of milliseconds and thus are suitable to offer fast frequency reserves. The challenge lays in the communication between the car and the party that sends the signal for the activation of the frequency reserves. As one C. B. Robledo (B) Process and Energy, 3mE,

Fuel Cell Electric Vehicle as a Power Plant: Techno-Economic Scenario Analysis of a Renewable Integrated Transportation and Energy System for Smart Cities in Two Climates

“…Similar to mobility as a service (MaaS) [214][215][216][217][218], power or electricity as a service (PaaS or EaaS) could be introduced. To create these markets, additional pricing structures, contract types, and aggregators scheduling and operating the cars will be required [219][220][221][222]. Upcoming technologies could facilitate the scheduling of cars, for example, self-driving, free-floating, cloud-connected car-sharing fleets [223][224][225], together with inductive (wireless) self-connecting V2G infrastructure [226][227][228][229][230].…”
