Critical Iridium Demands arising from future Expansion of Proton Exchange Membrane Electrolysis
Bernhard Wortmann, Detlef Stolten, Heidi Heinrichs
Proton exchange membrane electrolysis (PEMEL) is a key technology for producing green hydrogen, but its scalability is limited by the use of scarce materials, particularly iridium.…
Energy Storage Autonomy in Renewable Energy Systems Through Hydrogen Salt Caverns
David Franzmann, Thora Schubert, Heidi Heinrichs +2
The expansion of renewable energy sources leads to volatility in electricity generation within energy systems. Subsurface storage of hydrogen in salt caverns can play an important…
The Striking Impact of Natural Hazard Risk on Global Green Hydrogen Cost
Maximilian Stargardt, Justus Hugenberg, Christoph Winkler +3
Due to climate change, natural hazards that affect energy infrastructure will become more frequent in the future. However, to incorporate natural hazard risk into infrastructure in…
Countries across the world use more land for golf courses than wind or solar energy
Jann Weinand, Tristan Pelser, Max Kleinebrahm +1
Land use is a critical factor in the siting of renewable energy facilities and is often scrutinized due to perceived conflicts with other land demands. Meanwhile, substantial areas…
Participatory Mapping of Local Green Hydrogen Cost-Potentials in Sub-Saharan Africa
C. Winkler, H. Heinrichs, S. Ishmam +24
Green hydrogen is a promising solution within carbon free energy systems with Sub-Saharan Africa being a possibly well-suited candidate for its production. However, green hydrogen…
Mapping Local Green Hydrogen Cost-Potentials by a Multidisciplinary Approach
Shitab Ishmam, Heidi Heinrichs, Christoph Winkler +24
For fast-tracking climate change response, green hydrogen is key for achieving greenhouse gas neutral energy systems. Especially Sub-Saharan Africa can benefit from it enabling an…
