MIT team calls for carbon storage underground

摘要

Carbon from coal-burning power plants must be pumped underground to stop it contributing to climate change, according to a report, The Future of Coal, from scientists at the Massachusetts Institute of Technology in Cambridge. The team used a computer model to simulate a world in which carbon emissions come at a price. When the cost to emit a tonne of carbon reaches about US$30, it will begin to make economic sense to pay for it to be sequestered underground, the study found.
