A report by research institute Fraunhofer ISE highlights the importance of expanding electricity and hydrogen infrastructure to achieve climate neutrality in Germany by 2045. The report emphasizes the need for energy distribution between regions, especially from wind-rich northern states like Schleswig-Holstein and Lower Saxony, which are expected to supply a significant portion of Germany's primary energy through hydrogen by 2045. The study suggests that direct electrification, including the use of heat pumps, electric transport, and increased electrification in industry, is the most cost-effective approach to meet climate targets. Furthermore, the role of hydrogen as a supplementary energy source for industry, transport, and power generation is highlighted. Regional initiatives focusing on municipal heating, as well as expanding green electricity and hydrogen grids, are seen as crucial steps towards achieving climate neutrality. The report underscores the necessity of flexible energy generation and consumption to ensure a successful transition to a sustainable energy system in Germany.
