The advantages and drawbacks of co2 sequestration depend in large part on the methods employed. Capturing CARBON DIOXIDE gas and piping that underground is usually, as another answerer suggested, high-risk and likely inefficient. Although other methods may keep more assurance. For example , employing algae to sequester carbon dioxide, then burying the algae, eliminates the challenge of the trend of a gas to escape confinement. The major good thing about employing some sort of carbon sequestration technology is the fact it can, in effect, reverse a few fraction of your bad habits with regard to CO2 emissions. Unless we discover some way to sequester substantial quantities of carbon more cheaply than the difference among fossil fuel technologies and renewable energy systems, it won't provide us with carte blanche to keep applying fossil gas, but it can assist reverse a number of the past harm and/or support us ease the change to newer tech.
As far as Now i'm aware, clean coal generally does not label the LASER emissions from the coal, although instead towards the particulate emissions and the like. As such, while it can significantly decrease local pollution problems (relative to classic coal technologies), it will have no direct influence on global warming. In fact , it may indirectly make climatic change worse, since the absence of a smelly grow belching bad black smoke cigars may make people less willing to switch via coal to renewable solutions like sun, wind, and biomass.
Jyush, search for marine bare cement... we can help to make carbon-neutral concrete today. With respect to the engineering attributes needed, we may even be capable to make carbon-negative concrete.
