The energy systems are undergoing rapid changes, with increasing adoption of distributed renewable generation (from PVs and wind turbines), new forms of demand (from EV charging, heating) and storage. This poses significant challenges for our power networks, as seen in the significant network congestion issues emerging in many regions of the Netherlands. In recent years, hydrogen has enmerged as a significant energy vector, with potential to address many of the challenges posed by the energy transition. The Netherlands national hydrogen research programme on hydrogen, Groenvermogen NL (GVNL, https://groenvermogennl.org/) was established to perform fundamental and practical research required for realising and accelerating the hydrogen economy.
