A hydraulic lift is provided. The hydraulic lift may include a hydraulic cylinder defining a fluid chamber. The hydraulic cylinder may have a piston rod extending into the fluid chamber, a seal dividing the fluid chamber into a liquid chamber and a gas chamber, and a gas outlet from the gas chamber. The hydraulic lift may further include a pneumatic line in fluid communication with the gas outlet. The line may accumulate gas that is compressed in the gas chamber when the hydraulic cylinder is energized. The hydraulic lift may further include a load support for carrying a load and coupled to the hydraulic cylinder such that energizing the hydraulic cylinder raises the load support. The hydraulic lift is free of pneumatic tanks for compressed gas storage. A gas regeneration system and method of regenerating gas is also provided.
