Carbon dioxide in Earth's atmosphere able to synthesize food directly from and water using energy from light. However, not all organisms that use light as a source of energy carry out photosynthesis, since "photoheterotrophs" use organic compounds, rather than , as a source of carbon. In plants, algae and cyanobacteria, photosynthesis releases oxygen. This is called "oxygenic photosynthesis". Although there are some differences between oxygenic photosynthesis in plants, algae, and cyanobacteria, the overall process is quite similar in these organisms. However, there are some types of bacteria that carry out anoxygenic photosynthesis, which consumes but does not release oxygen. Carbon dioxide is converted into sugars
Carbon Recycling International as methanol fuel cells. Production of renewable methanol does not depend on agricultural resources, as hydrogen and carbon dioxide are the primary inputs. CRI's emissions-to-liquids production process is based on three main modules, carbon dioxide purification, hydrogen generation and the methanol synthesis and purification system. The catalytic conversion process from hydrogen and carbon dioxide occurs in one step, while production of methanol from fossil fuels, such as natural gas or coal, involves several reforming steps to obtain syngas followed by the catalytic step. The George Olah Plant, or the GO Plant, has a name-plate capacity of 5 million liters per
