Hydrogen has a low energy density by weight.

Hydrogen has a low energy density by volume.

Hydrogen is very challenging and dangerous to transport.

The input of energy to produce hydrogen is often greater than the energy of the resulting hydrogen.

Existing infrastructure for manufacturing and transporting hydrogen is minimal to nonexistent.

The energy required to operate and maintain the dam is often equal to the energy produced by the dam.

Dams often change the current and width of a watershed, altering the riparian ecosystem.

Many fish populations (including salmon and trout) are decimated because dams restrict access to essential habitat.

Dams can contribute to flooding and resulting property damage.

Animals that rely on fish as sustainance may begin to decline because the dam has permanently altered fish habitat.
