> [Australia] John Curtin University researchers engineered a catalyst that easily converts the byproduct into the carrier powder. This all forms part of the university’s Kotai Hydrogen Project. It has been found that adding water to 1 ton of sodium borohydride generates 213kg of hydrogen. Electrolyzers are then used to recharge the byproduct, making sodium borohydride 20 times more affordable than using ammonia, which delivers 178kg of hydrogen per 1 ton.
