Sugar looks pretty good.

Hydrogen has a molar mass of 1.008

Glucose (C6H12O6), molar mass 180.16g/mol. Density as a solid 1540
kg/m^3. Proportion Hydrogen by mass: (1.008 x 12) / 180.16 = 0.0671
Fructose (C6H12O6), molar mass 180.16g/mol. Density as a solid 1694
kg/m^3. Proportion Hydrogen by mass: (1.008 x 12) / 180.16 = 0.0671
Sucrose (C12H22O11), molar mass 342.30g/mol. Density as a solid 1587
kg/m^3. Proportion Hydrogen by mass: (1.008 x 22) / 342.30 = 0.0648

Thus a DTon (14m^3) of each has a following characteristics:
          Mass                  Mass of Hydrogen
Glucose  1.540 x 14 = 21.560   0.0671 x 21.560 = 1.45 tonnes
Fructose 1.694 x 14 = 23.716   0.0671 x 23.716 = 1.59 tonnes
Sucrose  1.587 x 14 = 22.218   0.0648 x 22.218 = 1.44 tonnes

Oleic acid, C18H34O2, (the primary constituent of olive oil) is even better.

Molar mass 282.47 g/mol. Density at room temperature 895 kg/m^3.
Hydrogen proportion by mass (1.008 * 34) / 282.47 = 0.1213. Thus
hydrogen per DTon: 14 x .895 x 0.1213 = 1.52 tonnes.

Looks like high-density hydrogen comes from agricultural worlds.
