1. A system, comprising:
a gasifier configured to convert a fossil fuel, oxygen, and water into a syngas comprising hydrogen and carbon monoxide;
a controller configured to control distribution of the hydrogen into a first portion and a second portion;
a solid oxide fuel cell (SOFC) power unit configured to receive the first portion of hydrogen and compressed air or oxygen, and generate electricity using the first portion of hydrogen; and
a chemical synthesis unit configured to receive the second portion of hydrogen and perform chemical synthesis using the second portion of hydrogen,
wherein the controller is configured to adjust the ratio of the first portion to the second portion of hydrogen based on a grid baseload and a percent load of the SOFC power unit,
wherein the controller comprises one or more processor and at least one tangible, non-transitory machine readable medium encoded with one or more programs configured to adjust a ratio of the first portion to the second portion of hydrogen,
wherein the ratio of the first portion to the second portion of hydrogen is controlled by the controller, and a percentage of the first portion of hydrogen is a product of the grid baseload and the percent load of the SOFC power unit.
