Abstract

A hybrid energy storage and delivery system can include a stationary hybrid energy storage and delivery system and a mobile hybrid energy storage and delivery system. The mobile energy storage and delivery system may include a hydrogen carrier unit and a mobile fuel cell unit. The mobile fuel cell unit can include a heat transfer system, a fuel cell, and a power exchanger. The system may include a mobile battery unit. The mobile battery unit can include a battery, a power exchanger, and a control. The system may include a medium voltage switch gear, including a first medium voltage transformer and a second medium voltage transformer. The first medium voltage unit and the second medium voltage unit can be connected to the medium voltage switchgear, and the medium voltage switchgear can supply electricity to a grid system.

Claims (50)
