The document describes a decarbonized combined cycle power plant. It uses methane reforming to produce hydrogen from methane and steam, separating out carbon dioxide. The hydrogen then powers gas turbines to generate electricity, while oxygen is separated and used in photosynthetic reactors with carbon dioxide to produce feed additives. This eliminates greenhouse gas emissions from the plant's operation beside water vapor.
