Integration of the environomic energy services for mobility and household using electric vehicle with a range extender of solid oxide fuel cell

Abstract

This article studies an innovative concept for vehicle propulsion, considered to deliver mobility services and integrated energy services for a household. An innovative converter – a Solid Oxide Fuel Cell with gas turbines system (SOFC- GT) is powering an electric vehicle. The vehicle architecture is as a serial range extender used to charge the high voltage battery. The range extender vehicle is optimized according to techno-economic and environmental criteria. It is researched to deliver optimal mobility and is integrated to the extended energy system, including the household needs. When the vehicle is unused is considered to be connected to the household and to deliver part of the energy services. In this configuration, the services of extended energy system are optimized. The environomic optimization concerns the extended energy system – vehicle and household and optimal designs for the integrated system are researched. The vehicle integrates energy services for mobility and household and becomes part of the large-scale energy grid for integrated services. The vehicle is sized for both uses. The major advantage of the energy integrated dual system is the reduction of the total global warming potential (GWP) impact with around 30000 kg CO2 eq. (60%). – from 50590 kg CO2 eq. to 20338 kg CO2 in comparison to separate energy services for mobility and household needs.
