Many medium sized Italian cities present pollution problems, due to their geographical position and climate conditions and mainly due to congested traffic flows. Impacts on the health of residents are becoming more frequent and also risky. Thus different policies have been proposed to reduce environmental effects. Among these, the use of low or zero emission vehicles both for private and public transport...
The world is beginning to embrace a transition from fossil fuel-based energy production and distribution methods to renewable energy-based methods. This is becoming more and more evident as governments around the world enact standards and regulations that require energy portfolios to be composed of ever-growing portions of renewable production. However, as this transition develops many questions and...
The electric revolution of mobility has left the cradle and is expected to breach the barrier of mass scale commercialisations within the next 3–5 years. To achieve that goal, the issue of range must be resolved. Especially plugin hybrid vehicles address this topic with a combination of batteries and a range extender. Range extender technologies hold a large market potential for the coming years and...
Massive utilization of fossil fuels presents serious environmental threats. In this context, today the development of renewable energies is an urgent issue. Due to the stochastic nature of renewable energy sources an energy storage is needed in renewable energy generation systems. Hydrogen-based energy storage system or hydrogen buffer can help to stabilize unregulated renewable energy generation...
The existing energy is almost provided by carbon-containing fossil sources such as oil and coal. The rapid consumption of these fossil resources causes an accelerated release of CO2 which is a major cause of global warming and associated climate change. “Green” bio-methane (also named biogas) has the advantage for both reducing over dependency on fossil energy and reducing emissions o CO2 and other...
Distributed generation (DG) is one of the most important innovations in the power systems. Among different types of distributed generation, fuel cells attract lots of attentions. The purpose of this paper is to discuss all types of fuel cell and their roles in the DG. The operational principles of each type are also explained. According to definite technical-economical indexes, comparison of these...
