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 damage Hydrogen damage Hydrogen damage is the generic name given to a large number of metal degradation processes due to interaction with hydrogen. Hydrogen is present practically everywhere, several kilometres above the earth and inside the earth. Engineering materials are exposed to hydrogen and they may interact with it resulting in various kinds of structural damage. Damaging effects of hydrogen in metallic materials have been known since 1875 when W. H. Johnson reported “some remarkable changes produced in iron by the action of hydrogen and acids”. During the intervening years many similar effects have been observed in different structural materials, such
