Largest Carbon Sequestration Plant To Pump 3.3 Million Tons Of CO2 Into Ground
Even before a single ounce of natural gas gets burned in
a home or power plant, massive amounts of CO2 have already
been released. The process of extracting natural gas releases
carbon dioxide pent up in the same wells as the gas, thus
adding to the climate-changing impact of the fuel.
To help lower the global warming impact of one of the world's
largest natural gas fields, General Electric has supplied
Chevron, Exxon Mobile and Shell with enough compression
"trains"--the pumps and turbines that do the sequestering--to
create the world's largest carbon sequestration project. The
trains will pump 3.3 million tons of CO2 released from
natural gas mining back into the ground every year. That's
the equivalent of taking 630,000 cars off the road.
The project, called Gorgon, won't go online for a couple of
years, and GE won't begin building the equipment trains for
at least another year or two. Once built, the trains will
redirect the CO2 back into an underground chamber 1.5 miles
under the ocean.
Naturally, this process does not stop the natural gas itself
from releasing greenhouse gases when burned for fuel. And why
name a project aiming for environmental soundness after
a terrifying monster with snakes for hair and a gaze that
turns men to stone? Someone at GE needs to get a copy of
Bulfinch's Mythology.
