Hydrogen represents a key part of the energy mix on the global path toward carbon neutrality. This emergent fuel is a leading contender to be a sustainable, seasonal energy storage solution, could be used to balance the short-term intermittency of wind and solar and is easily transported using modified natural gas infrastructure.
However, the green hydrogen value chain is set to be more complicated than any current energy-carrying vector. It will be broader, more complex, and have more stakeholders. Therefore, optimising green hydrogen production will rely on visibility across the value chain.
The multiple uses of hydrogen
The concept of hydrogen energy storage is based on the ability to use excess renewable electricity to run the hydrogen production process. Hydrogen can be safely stored in underground caverns and eventually re-electrified when needed. The stored hydrogen can produce electricity from a fuel cell or by flowing into a specially designed turbine.
