Connected Strategy for Hydrogen Value Chain ^ Top ^ 29 Figure 12 | Avoiding grid reinforcement using storage technology Hydrogen is a zero-carbon source that avoids CO2 and particulate emissions, can be deployed at large scale, and be made available everywhere via distributed energy resources (DERs). Using DERs for power- to-hydrogen solutions has the added benefit of avoiding grid modifications (Figure 13). Hydrogen is hence the “missing link” in the energy transition: renewable electricity can be used to produce hydrogen, which can in turn provide energy to sectors otherwise difficult to decarbonize through electrification. Hydrogen can add supply-side flexibility and offer seasonal storage of solar and wind power. Figure 13 | Flexibility in the Energy Supply Chain9
