Latest Patents

Niemann's latest patents include a method of generating hydrogen-storing hydride complexes. This invention features a ternary hydrogen storage system with a constant stoichiometric molar ratio of LiNH:MgH:LiBH of 2:1:1. The incorporation of MgH particles, approximately 10 nm to 20 nm in size, has been found to lower the initial hydrogen release temperature to 150°C. Additionally, the particle size of LiBNH quaternary hydride significantly affects hydrogen sorption concentration, with an optimum size of 28 nm. The synthesized hydrides demonstrate two main hydrogen release temperatures, one around 160°C and the other around 300°C. Notably, the main hydrogen release temperature has been reduced from 310°C to 270°C, with hydrogen being reversibly released at temperatures as low as 150°C, achieving a total hydrogen capacity of 6 wt. % to 8 wt. %. Detailed thermal, capacity, structural, and microstructural properties have been correlated with the activation energies of these materials.
