However, if energy production is cheap or baseload renewable energy (i.e. bio-
mass) is limited, the ineffi ciencies of the hydrogen energy system may be attrac-
tive. Therefore, a lot of potential exists but more research is required to truly
quantify the benefi ts and drawbacks of each system.
Finally, it is evident from this chapter, that energy storage systems provide a
much more promising solution to the integration of intermittent renewable energy
than individual technologies. Energy storage technologies will most likely improve
the penetrations of renewable energy on the electricity network but disregard the
heat and transport sectors. Consequently, energy storage systems could be the key
to fi nally replacing the need for fossil fuel with renewable energy.
