The Capture and Sequestration of Carbon Dioxide | | |
Pipeline
This is an existing technology that is used for the CO2 enhanced oil recovery. As CO2 is easily handled
and is large inert, it can be
transported at high pressures through pipelines. There is at present about 3,000 km of pipelines already
in existance, mainly in North
America.
It already has already internationally recognised standards for the design, construction and monitoring
of the pipelines.
The transportation costs of piping the
CO2, would be typically cheaper than it to tranmit the equivalent amount of electricity. This means
that it would be cheaper to site the power station close to the elctricity demand, rather than next
to the disposal site of the CO2.
Further work needs to be carried out into the conditions that may or may not cause CO2-induced corrosion.
Other issues that required some study will be the rights of way, that is the planning procedures and
gaining of access to the land that the
pipeline would be lay on or under. Much of this could be similar to those currently used for natural
gas pipelines, but some additional
measures may have to be taken. Also in order for this to be possible there has to a general public acceptance
of this method of
transportation of the CO2. So some work should be carried out in finding out if the public would accept
this method and the education of
the public in the issues involved with pipeline transportation.
