Hydrogen can be made to explode in two different ways. The most usual way would be by combustion with oxygen, but that requires ignition. However, if you have liquid hydrogen you could make it explode by heating it, even in the absence of oxygen, in exactly the same way that water in a sealed container will explode if you heat it to the boiling point. Liquid hydrogen, of course, has a much lower boiling point than water does, and therefore would require less heating to make it explode. If it is not kept cooled, it will explode even at room temperature.
