Electrochemical Step Towards A Better Hydrogen Storage
Hydrogen is seen as a versatile energy carrier for the future but the element does not occur in the free state on Earth. Therefore, it must be first generated then stored, to be finally used. Hydrogen storage represents, however, a serious challenge.
Researchers at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw managed to apply a user-friendly electrochemical method to study hydrogen diffusion in highly reactive metals. The drawbacks of conventional storage tanks for gaseous and liquid hydrogen make us to look for other solutions. One of the promising methods for hydrogen storage makes use of the capability of some metals and alloys to easily uptake this element. The development of efficient hydrogen storage systems requires, however, a detailed knowledge on how hydrogen diffuses in metals.
“We managed to overcome this obstacle”, says Prof. Tadeusz Zakroczymski, whose team at the Institute of Physical Chemistry of the Polish Academy of Sciences (IPC PAS) in Warsaw has been for many years carrying out comprehensive research on hydrogen permeation, diffusion and uptake in metals.
If you want to know more about this and other topics directly from end users of energy storage technologies join us at one of these annual events: The Energy Storage World Forum (Grid Scale Applications), or The Residential Energy Storage Forum, or one of our Training Courses.
