Abstract
The present invention is an energy generating system which uses Lithium Metal Polymer (LMP) batteries in conjunction with a microturbine, a fuel cell, and commercial electrical power. The LMPs provide uninterruptible power when one or more of the other power systems fail.
Claims20
A power supply system for providing electrical power comprising:
- an on-site turbine adapted to combust a first gas and generating a source of alternating current (AC);
- a conversion device for converting said first source of AC into a first optional source of direct current (DC);
- a lithium-comprised energy storage device providing a second optional source of DC used for one of backup and bridging purposes.
A power supply system comprising:
- a turbine for combusting a gas and generating a first source of alternating current (AC);
- a conversion device for converting said first source of AC current into a first source of direct current (DC);
- a lithium-comprised energy storage device providing a second source of DC current used for at least one of backup and bridging purposes;
- and
- a fuel cell for generating a third source of DC current.
2 more elements
A method of supplying power comprising:
- combusting a gas in a micro-turbine to produce a first source of power;
- importing a second source of power from a commercial electric utility in the event said first source of power becomes unavailable;
- and
- using a lithium-comprised energy storage device to provide an additional source of power if both said first and second sources are unavailable.
