Abstract

Method and apparatus for standby fuel storage and use to provide uninterrupted power generation by a power generation mechanism. An infrastructure pipeline supplies natural gas at a selected flow rate and a selected pressure as a primary fuel. A secondary fuel is accumulated in a plurality of sub-surface storage pods. In response to an exception event such as a curtailment order, a controller throttles a subsequent flow of the natural gas from the infrastructure pipeline so that the natural gas continues to flow to the power generation mechanism at a reduced flow rate, and blends the reduced flow of the natural gas with the secondary fuel. The secondary fuel can be an additional quantity of natural gas, hydrogen, or some other fuel. Renewable energy sources such as wind or solar can be used to generate the hydrogen, even during the blending process. The blend ratio can be adaptively adjusted.
