Carbon Bad

Carbon, in some forms, is bad for us and bad for the planet. As particulates, in diesel vehicle exhaust, it penetrates our lungs. As soot, it pollutes generally and stains buildings. Combined with two oxygen atoms, as carbon dioxide, it makes carbonated drinks fizzy and is classified as a green-house gas.

It's difficult to get rid of CO₂. The seas dissolves a significant quantity of CO₂ but this acidifies the oceans and has a serious effect on shellfish and crustacians.

One way to reduce CO₂ is to collect it where it is created - at the power station. There are a number of ways to collect CO₂:

Pre-combustion process
Post-combustion process
Oxyfuel capture
