Governments around the world are trying to reduce emissions
of carbon gases because these are responsible for global warming. Australia has
made the first step in this process. A large underground carbon storage
facility was opened in the southern state of Victoria,
near the town of Warrnambool, west of Melbourne. It will
capture carbon dioxide from a power station and store it two kilometers beneath
the surface. Rock formations will be used. These will absorb like giant sponges
the carbon dioxide. It will be compressed into a liquid and stored underground.
On the one hand, researchers are optimistic, saying that the
program will help Australia
make deep cuts into its greenhouse gas emissions, the Voice of America reports.
On the other hand, environmentalists are not so convinced
that this will work. They are concerned that leaks from underground facilities
could have harmful effects in the future. But Peter Cook, one of the product’s
architects assures them that the experiment will be “the most comprehensive
monitoring program for stored carbon dioxide anywhere in the world.”
“You've got to, A: capture the CO2 [carbon dioxide], so
you've got to get a hold of it first of all, then you compress it effectively
into liquid form and you pump it down into the ground somewhere where it's
securely kept for a long time,” professor Victor Rudolph, a chemical engineer
at the University of Queensland explained, quoted by the same newspaper. “So,
you've got to either find a cave or a space and something that seals it within
that space then it just stays there forever.”
He is convinced that this will be one of the largest
projects in the world and a real test of geo-sequestration under Australian
conditions.
