Carbon capture and utilization in the soil permanently. A carbon-neutral fuel can be synthesized by using the captured CO from the atmosphere as the main hydrocarbon source. The fuel is then combusted and CO, as the byproduct of the combustion process, is released back into the air. In this process, there is no net carbon dioxide released or removed from the atmosphere, hence the name carbon-neutral fuel. An example of the technology include biofuel from microalgae as discussed below. Methanol, or ethyl alcohol, is the simplest member of the family of alcohol organic compound with a chemical formula of CHOH. Methanol fuel can be
Hydrogen economy conversion methods, the efficiency of distributed hydrogen production would be roughly 25%. The distributed production of hydrogen in this fashion would be expected to generate air emissions of pollutants and carbon dioxide at various points in the supply chain, e.g., electrolysis, transportation and storage. Such externalities as pollution must be weighed against the potential advantages of a hydrogen economy. One of the main offerings of a hydrogen economy is that the fuel can replace the fossil fuel burned in internal combustion engines and turbines as the primary way to convert chemical energy into kinetic or electrical energy; hereby eliminating greenhouse
