1. Introduction The recuperation of kinetic energy of trains is an old-decade problem and attracted the interest of many scientists. Although some authors proved that the train energy consumption could be reduced only by implementing suitable driving stiles (Bocharnikov et al., 2007, Sheu and Lin, 2011), the energy recovery seems to be more …
Furthermore, even in case of a hydrogen-powered airship like advertised in industry (Clipper H2 2022 ), the costs per ton-mile are estimated to be from USD 0.177 to 0.247 per ton-mile for distances between 1000 and 6000 miles. The solar-powered airship exhibits an advantage in energy consumption costs. Table 6.
An onboard energy storage system (OESS) withfast-energy-exchange capability is needed to enable future grid-to-vehicle (G2V) and vehicle-to-grid (V2G) operations. To facilitate the fast energy exchange, the OESS normally interfaces between a high voltage (HV) bus on the grid side and a low voltage (LV) bus on the vehicle side. The HV bus can …
The optimization of the train speed trajectory and the traction power supply system (TPSS) with hybrid energy storage devices (HESDs) has significant potential to reduce electrical energy consumption (EEC).
