Hydrogen is recognized as a crucial element in decarbonizing the CO₂ intensive economy, with green hydrogen being particularly promising due to its potential to significantly reduce emissions. In Germany, green hydrogen is not yet competitive compared to fossil fuels, necessitating the establishment of a new market. Limited space for renewable energy expansion and location-related advantages in other countries highlight Germany's reliance on hydrogen imports, emphasizing the need for cooperation and political support. KfW's involvement in constructing the hydrogen core network underscores the network's importance in enabling widespread hydrogen use. The network, connecting production sites with consumption centers, is essential for industrial decarbonization and energy sector transition. The financing model, including the innovative amortisation account, ensures cost distribution and financial stability. The cooperation between stakeholders is crucial for the success of this infrastructure project, demonstrating the commitment to advancing green hydrogen in Germany.
