Current developments are strongly directed towards renewable electricity generation using wind farms and solar panels and partly to generate Hydrogen as energy storage to overcome the variability of these sources.

Only storage in molecules can store sufficient energy to bridge significant gaps in the production by renewables. But the limitations and challenges related to Hydrogen are grossly underestimated: the required electrical power, the additional hardware, and the clean water supply.

So, what are the significant challenges at this moment and in the future?

In this whitepaper, the following topics are discussed:

• – The required electrical power
• – Capacity of electrolysers
• – Natural Gas versus H2
• – Transport of H2
• – Reducing wasting energy
