Figure: The energy change associated with hydrogen removal from silicon carbide nanotubes

Caption

The graph shows the variation of system energy with the distance of a hydrogen molecule from the surface of a silicon carbide nanotube (bottom right). The depth of the curve signifies the energy required to extract hydrogen from storage. A comparison of prediction methods is presented, with DMC being the most accurate and vdW-DF2 being its closest match.
