Latest Patents

Ahrens' latest patents include a Compressed Air Energy Storage System and an Air Ejector Augmented Compressed Air Energy Storage System. The Compressed Air Energy Storage System utilizes an internal combustion reciprocating engine that operates as a compressor during slack demand periods. This system charges air into an air storage reservoir using excess power from the power grid. During peak demand periods, the engine functions as an expander, feeding power back into the grid by utilizing air from the storage reservoir along with combustible fuel. The design incorporates high-pressure operation and employs a low-pressure turbine and compressor for efficient air compression and power generation.

The Air Ejector Augmented Compressed Air Energy Storage System stores energy during slack demand periods by charging multiple underground reservoirs with air to a peak storage pressure. During peak demand, the system throttles air from one reservoir into a gas turbine system at a constant inlet pressure. As the air pressure in the first reservoir decreases, air from a second reservoir flows into the gas turbine system. This process is enhanced by a variable geometry air ejector, which maintains the air flow at a constant inlet pressure.
