  • Using water containing deuterium instead of hydrogen enabled the researchers to trace how much hydrogen is generated from the hydrolysis reaction and how much from the thermolysis reaction − details critical to understanding the process.

  • In hydrolysis, water is combined with ammonia borane and the process requires a catalyst to generate hydrogen while, in thermolysis, the material must be heated to more than 170°C, or more than 330°F, to release sufficient quantities of hydrogen.

    The Engineer - News

  • The process combines hydrolysis and thermolysis, two hydrogen-generating processes that are not practical by themselves for vehicle applications.
