The term hybrid energy system refers to those applications in which multiple energy unit conversion devices are used together to supply an energy requirement. These systems are often used in isolated applications and normally include at least one renewable energy source in the configuration. Hybrid energy systems are used an alternative to more conventional systems, which typically are based on a single fossil fuel source. Hybrid energy systems may also be used as part of distributed generation application in conventional electricity grid. (more…)

A number of countries have vehicle tax incentives programs designed to reward purchasers and owners of alternative fuel-efficient vehicles (or to penalize purchasers and owners of fuel in efficient vehicles) by tying vehicle purchase and/or ownership taxes either directly to fuel economy or to vehicle features associated with fuel economy (e.g., engine displacement).

Mercedes-Benz presented at Geneva Style F800 Concept (the F stands for Mercedes: technology, design and art), a prototype that shows the path that the firm will design and technological advances in the recent future.

The platform can equip the F800 fuel cell systems and hybrid plug, through the use of compartments in the frame for storing hydrogen fuel cells and lithium ion batteries. (more…)

The most commonly researched and most developed application of using hydrogen as a fuel source is in conjunction with a hydrogen fuel cell. Fuel cells operate by mixing hydrogen and oxygen to produce water and electricity. The electricity can then be used to provide power to homes, schools, and even businesses or to power cars and other vehicles. Some experts believe that internal combustion engines (ICEs) that are fueled by hydrogen are just as important. Hydrogen could be used as fuel for transportation by creating internal combustion engines for vehicles that run on hydrogen or hydrogen fuel mixtures. (more…)
