Hydrogen is becoming one of the key energy carriers for the future to deal with the challenge of climate change and achieve the goals of the Paris Agreement, also because it can help to compensate for the intermittency of renewable energy resources, while it can be sustainably produced from e.g. solar and wind power through the electrolysis of water. Large-scale usage of H2, however, will necessitate its storage at massive scales. Multiple H2 storage options exist, among which through the production and use of NaBH4, associated with the regeneration of the spent fuel NaBO2.
It is the purpose of this research project to develop and assess NaBH4 as circular H2 storage option. Also a comparison will be made of the techno-economic features between H2 usage from NaBH4 storage and the direct usage of NaBH4 in fuel cells to generate and use electricity.
