Climate Change appears to be one of the biggest challenges for mankind. For a successful defossilization a sector coupling based on renewable energies will play a key role. Hence, the metropole Hamburg plans in the Port of Hamburg with an electrical power of 100 MW the world biggest hydrogen electrolyser based on renewable electricity. Since Germany is a country with a high population density space availability for renewable energy generation is limited and high conversion efficiencies are desirable. Therefore, the use of waste heat of the hydrogen electrolysis can be a promising option to higher overall efficiencies.
The main aim of this Thesis is the development and techno-economic assessment of concepts for the waste heat use of a 100 MW electrolyser in Hamburg. First an examination of the occurring heat flux and needed devices for a baseload as well as a fluctuating hydrogen production will take places. Afterwards a concept for the waste heat use and specific local costumers will be identified. This may contain local heating networks and heat pumps. Thereupon a techno-economic assessment of the developed concepts will take place, completed with a comparison to other (renewable) heat supply systems. The Thesis can be written in German or English.
The thesis can be prepared in German or English.
