A highly efficient, utility scale energy storage system employs large masses transported uphill to store energy and downhill to release energy. An electric powered cable winch or chain drive shuttles the masses between two storage yards of different elevations separated by a steep incline on rail vehicles supported by track and operated by an automated control system.

Ridgeline cable drive electric energy storage system

A power supply and control system for electrically powered shuttle-trains incorporates at least one shuttle train having a motor and a generator. A first plurality of track segments has associated synchronous power modules exchanging power synchronously with a power grid through a plurality of power supply rail segments connectable to the motor or generator. A second plurality of track segments has associated variable frequency power modules exchanging power through a second plurality of power supply rail segments connectable to the motor or generator. Isolation segments separate adjacent power supply rail segments. A control system interconnected to the variable frequency power modules controls the frequency of each variable frequency power module based on the location of the shuttle train.

Combined synchronous and asynchronous power supply for electrically powered shuttle trains

A potential energy storage system incorporating multiple track mounted shuttle units having motor/generator drive bogies and structure with an integral transfer mechanism for removably carrying energy storage masses from a first lower elevation storage yard to a second higher elevation storage yard employing excess energy from the electrical grid driving the motors, removing the masses in the second storage yard for energy storage, retrieving the masses and returning the masses from the second storage yard to the first storage yard recovering electrical energy through the generators.

Utility scale electric energy storage system

A fluid transfer engine employs a case with a cylindrical inner wall having an operating radius extending from a case axis. A main rotor is carried within the case and incorporates a lobe with a major radius equal to and concentric with the operating radius of the case, the main rotor having a minor radius defining a body. Two peripheral rotors are diametrically opposed with respect to the case axis and rotate within rotor chambers extending from the case. Each peripheral rotor has a radius equal to the minor radius and a center of rotation located at twice the minor radius from the case axis. Each of the peripheral rotors rotates in uniform circular motion with the main rotor in sealing contact with the body and incorporates a sculpted recess for receiving the lobe of the main rotor.

Multiple rotor fluid transfer engine

A utility grid ancillary services system employs an inclined track with a utility grid connection system associated with the track. Shuttle units ride on the inclined track and have a motor/generator and an onboard electrical system for control. The motor/generator is connected to draw power from or provide power to the utility grid connection system. A controller in communication with an electric utility controls the onboard electrical system. Software modules in the controller increase uphill force responsive to a regulation down command from the utility thereby absorbing additional power from the utility grid or decreasing the amount of power provided to the grid. The software modules decrease force in an uphill direction responsive to a regulation up command from the utility thereby generating additional power to supply the utility grid or decreasing the amount of power absorbed from the grid.

Rail based potential energy storage for utility grid ancillary services

A rotary engine with multiple pivotally mounted lobes desmodromically extendible and retractable from a rotor to trace asymmetric volumes for inlet and compression and expansion and exhaust based on the contour of the engine case which the lobes sealingly engage.

Multilobe rotary motion asymetric compression/expansion engine

An asymmetric complete-expansion thermodynamic engine cycle is provided by an engine which compresses an air/fuel mixture to a given ratio, ignites and combusts the mixture, and expands the products through a power stroke to a volume substantially larger than the compression volume before being vented and purged to the atmosphere. This cycle is performed by a non-axisymmetric main rotor revolving within a cylindrical housing. Sealing means associated with the main rotor provide for the varied compression and expansion volumes. The cylindrical housing also contains means for air intake, fuel injection, venting, and spent gas exhaust porting.

Asymmetric complete expansion rotary engine cycle

A thermodynamic cycle for an internal combustion rotary engine is disclosed which achieves high efficiency through an asymmetry between the volume of air charge before compression and the volume of expanded air at the completion of expansion. The expanded volume is ideally selected such that the pressure of the exhaust gases is near the ambient pressure of the intake air. Three embodiments of engines which utilize the cycle are disclosed, one with the major components operating in uniform circular motion, one which utilizes lobe valves, and one which utilizes three sets of lobe valves such that three charges of air at various stages in the cycle are in the engine, thus increasing the power density of the engine.
