1) The document discusses carbon capture and storage (CCS) technology, which captures carbon dioxide emissions from coal-fired power plants and stores it underground.
2) It provides an overview of CCS regulatory frameworks and projects in the US and globally. Many countries have developed CCS regulations, though standards vary significantly.
3) Transportation of captured CO2 is mainly through pipelines, with existing pipeline networks in the US and Europe. Offshore storage also utilizes shipping. Transportation costs range from $1-5 per ton of CO2 transported 250km.
