Capturing carbon to store it safely underground
is this a new idea in
nature has been storing co2 underground for millions of years
it's often found with oil and gas the and for decades shell and other
companies have injected co2 into reservoirs to boost oil recovery
my some man-made co2 is captured and used for example to the fees into soft
the mall to help tomatoes grow
how the co2 captured industrial sites that burn fossil fuels such as power
steelworks and refineries a major emitters of co2
there are three ways to separate co2 from the other gases
mmm using chemicals to absorb co2
from chimney stack emissions or gas a fine coal biomass
to produce synthesis gas from which chemicals or special filters extract co2
theme or burning fossil fuels with pure oxygen
produces a highly concentrated stream of co2
which can be separated from impurities once the co2 has been separated
it is then compressed and sent by pipeline or tanker to a long-term
storage site and
pipelines have carried co2 for more than forty years
over 5,000 kilometers of CO two pipelines exist in the USA alone
ba wary co2 storage the new
potential storage sites a carefully selected and monitored every stand
hmm co2 can be injected into depleted oil and gas reservoirs
or saline formations
generally adept serve over a kilometer and where an impenetrable
camp rock seals it in when over time the co2 will dissolve
%uh some co2 will for minerals
