As a gas, it often requires high pressure. As a liquid, it requires extremely low temperatures.   
   
In both cases, safety and infrastructure become major considerations.  
   
That is why I find the approach of H2FLEXX interesting.  
   
Instead of transporting hydrogen as a gas or liquid, hydrogen is temporarily bound to a powder-based solid carrier.   
   
That makes transport easier and safer.  
   
At the point of use, water is added. The reaction releases hydrogen, ready for use.  
   
After the hydrogen has been released, a residual material remains.   
   
H2Flexx has already worked on one of the crucial steps: making that conversion back into new hydrogen carrier material scalable and practical, which supports a circular system.   
   
This makes the difference between a clever chemical reaction and a scalable system.
