Fraunhofer researchers from Dresden have developed a technique for storing energy in a hydrogen-rich paste and making it usable again in a simple way.
For decades, visionaries have been dreaming of an economy based on hydrogen as an energy source. But harnessing the lightest chemical element for use in everyday applications is a technological challenge. For example as a fuel in cars, ships and airplanes: Unlike petrol, diesel and kerosene, hydrogen is gaseous and highly volatile at normal ambient temperatures and normal air pressure. To put it in a tank, it has to be extremely...
