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…)

In many countries of the world wind power expands and covers a steadily increasing part of these countries’ power demand. Growing wind power has impacts on the power systems into which the wind turbines feed their power. As wind power penetration increases, the respective power system operators are concerned about the stability and reliability of their power systems. Therefore, more and more power system operators revise their gird connection requirements and issue grid connection requirements specifically made for wind turbines and wind farms. (more…)

The internal combustion engine has dominated the car and light-truck market for over 100 years. Although remarkable improvements have been made over the past 30 years to reduce air pollutants to nearly zero and to almost double vehicle efficiency, increasing concerns about global warming and energy security are pushing vehicles toward even greater efficiency.
