Some technologies help capture carbon lanidride already produced and released in the air.
However, although these technical solutions exist, the political decision making and industrys remains slow.
The Carbon Capture and Storage (CCS) which enables carbon capture a set of technologies that reduce emissions of CO 2 in the air.
The CO 2 that is captured is then transported and buried in a storage site often it is emptied of oil fields that lie in the seabed.
So far it has been demonstrated in laboratories, pilot plants and in electrical and industrial plants in the world.
C was an evolution in the last 20 years.
a fully recognized technology and secure said Professor Katherine Romanek delluniversit Texas, during the Cop25 conference.
Even in Texas in 1972 we have been pioneering experiments of this practice, for the first time by injecting CO2 into an oilfield.
The fifth assessment report of the Intergovernmental Panel on Climate Change (IPCC) clearly in the field of CCS: defines a technology necessary to maintain an increase in global temperature levels within the limit of 1.5 degrees provided dallaccordo Paris.
Today, the CCS facilities around the world are capturing more than 35 million tons of carbon dioxide per year, equivalent to the annual emissions dellintera Ireland.
The report released by international think tank Global CCS Institute reveals the latest statistics on this technology.
Currently there are 51 of the capture and storage of carbon on a large scale in operation or under development at the global level, in a variety of sectors and industries.
These include 19 plants in operation, four construction and 28 in various stages of development.
In Europe, there are 10 structures CCS on a large scale in various stages of development (6 in the UK, 2 in the Netherlands, 1 in Norway, 1 Ireland).
When operational, these structures will capture about 20.8 Mtpa CO 2.
The interest in this technology in the second half but still lagging behind, while emissions increased again nellultimo year.
said Brad Page, the administrator delegate of Global CCS Institute.
C needs more political support for lallocazione capital for this technology has continued.
Industrial output a driving factor of global warming: the largest source of carbon emissions are large coal-fired power plants and industrial plants that produce everyday products.
A transition to an economy with low carbon emissions would also be possible through inflator implementation of CCS technology, since CO 2 emissions would be almost completely eliminated.
However the cost of CCS involves partly capital investment on equipment to capture, transport and store carbon dioxide, and many multinationals around the world are reluctant to invest to bear the operating costs dellattrezzatura to store CO 2.
To manage part of these financial flows would be the current oil companies, which immetterebbero lanidride carbon where before they extracted oil.
The main fear is that the NGOs to oil companies linked to the possible loss of CO 2, for quite different reasons.
Injecting carbon dioxide into the oil fields would make the oil companies or industries responsible for permanent storage, with a need to compensate those that may be affected by a leakage of carbon dioxide.
The monitoring, measurement and verification are key components for CO 2 storage campaigns and increase costs.
European The Union has a fund for innovation with an expected value of 10 billion to be spent over the next few years, part of this could be used to help build the first factories to lower carbon emissions and empower the industry, encouraging the system to create the necessary infrastructure for CCS.
The new European Commission seems to be conducive to the development of this technology in Europe, but only in the coming months, including through the European Green New Deal, there will be more concrete answers.
