Many railway vehicles use diesel as their energy source but exhaust emissions and concerns about economical fuel supply demand alternatives. Railway electrification is not cost effective for some routes, particularly low-traffic density regional lines. The journey of a regional diesel–electric train is simulated over the British route Birmingham Moor Street to Stratford-upon-Avon and return to establish...
Wider use of fossil fuels is prohibited by unfavourable recent climate change phenomena as well as constraints from greenhouse gasses emissions, regulated strictly by the European Union. Fuel demanding sectors, such as transportation, impose utilisation of environmentally friendly technologies which will contribute in increased hydrogen production, which is considered as energy carrier for future...
This paper describes a combination of photovoltaic (PV) and fuell cell (FC) hybrid energy system for stationary applications. The system includes solar panels and a FC system working in parallel, an electrolyzer system, power manager unit and storage tanks for the compressed hydrogen. In this hybrid energy system, if the solar radiation level is high enough, the PV array powers the load and the excess...
This article examines the use of hydrogen as fuel for transport applications and the problems encountered in its storage. Firstly it outlines the current compressed hydrogen and liquid hydrogen schemes and their drawbacks. It then focusses on the use of solid state and porous storage materials such as metal hydrides and the ongoing research in this area. The goal is to develop a solid-state hydrogen...
