Osaka University researchers developed a system where hydrogen is separated and stored in liquid organic hydrogen carriers.
researchers from Osaka University have made exciting progress toward eliminating many of the remaining bottlenecks in using hydrogen as an energy carrier.
For the commercial use of hydrogen, all contaminants must be rigorously removed by multistep, energy-intensive processes that are independently optimized for each contaminant, making it difficult to extract the hydrogen from the crude mixture containing the by-products. To overcome these challenges, Hoshimoto and his team have synthesized shelf-stable triaryl boranes that took up hydrogen even in the presence of common contaminant gases, achieving the following ground-breaking results: hydrogen storage and subsequent hydrogen release at a purity of up to 99.9%.
