In Hanover, hydrogen will make an important contribution to climate protection in municipal water management in the future. E-Bridge (Philipp Heuser and Andreas Gelfort) supports Stadtentwässerung Hannover (SEH) in planning an innovative model project for the production and use of green hydrogen. Together with SEH, E-Bridge has developed procurement strategies for green electricity and an assessment of future hydrogen competitiveness. The options for action derived from this and jointly evaluated serve to assess the investment decisions and the significant parameters on the revenue side that influence the sustainable profitability of the project.
