The equation for potential energy is U = m ⋅ g ⋅ h, so higher density factors into higher mass (per unit volume) so directly into higher energy storage capacity

The equation for potential energy is U = m ⋅ g ⋅ h, so higher density factors into higher mass (per unit volume) so directly into higher energy storage capacity.

- jjk166 3y agoWhich falls under the category of component sizing. But assuming you have however much mass at a given height, a denser fluid won't let you extract the same amount of energy from a lower height, which is what the company is claiming.
