Climate Change Drives The Need For Ccs Carbon Sequestration

Capture of carbon dioxide from the air

Energy Agencies in Europe and the United States agree on the importance of CO2 capture and storage as one of the solutions to climate change.

In the fight against climate change and the pursuit of sustainability, the United Nations Economic Commission for Europe has highlighted the importance of carbon capture and storage ( CCS ) as a clean energy solution.

The European Union Energy Agency announces in a statement that “policy parity and the rapid acceleration of CCS facilities are essential to meet the Paris climate change targets” according to climate experts, including Dr. Julio Friedmann, Deputy Secretary of the Office of Fossil Energy at the US Department of Energy.

To make such assertions, they refer to the 2017 CCS report, presented at the Conference of the Parties (COP23) in Bonn, the director general of CCS, Brad Page, has commented that “ renewable energies alone would not meet the objectives international organizations to fight against climate change, and the opinion of the experts was conclusive that the CCS must be part of a set of clean technologies necessary to achieve the objectives ”regarding the reduction of 2ºC.

According to Page’s comments, in the last year there have been ” significant advances in the number of facilities deployed and the knowledge of CCS as a fundamental solution for climate change is the highest that has ever existed”. In reference to the Paris objectives, he stated that “the most serious analysis has concluded that it will be very difficult to achieve the objectives without carbon capture and storage or use.”

What is CCS?

The method is a process that is based on the separation of Carbon Dioxide, CO2, emitted by the industry, among other sources related to the generation of energy through combustion processes and the transport that takes it to a site for storage. geological, thus isolating itself from the atmosphere in the long term. This would be in the terrestrial or marine subsoil, since the studied option of taking it to the sea has been discarded due to the problems that it would entail for marine ecosystems.

This system is designed to be applied in large coal and gas thermoelectric plants, both those of new design and the adaptation of existing ones.

CO2 is compressed almost to the point of liquefaction, according to forecasts this system can accommodate up to 90% of emissions, although once the reductions due to losses in capture, transport and storage have been taken into account, they can be captured up to 80% of CO2 emissions.

Highlights in the global state of CCS.

At the Paris Climate Conference (COP21), held in December 205, more than 190 countries signed the first agreement that bound them in the fight against climate change.

Among the objectives to be highlighted is to maintain the increase in the global average temperature “well below 2 degrees Celsius” above pre-industrial levels.

Another objective is to limit the increase to 1.5ºC, which would considerably reduce the risks regarding the impact of climate change.

Along the same lines, it has also been stressed that global emissions reach their maximum level as soon as possible, although it is recognized that in developing countries this process will take longer. It was also agreed to apply later rapid reductions based on available scientific criteria.

In order to achieve the objectives, it has been agreed to strengthen the capacity of societies to face the consequences of climate change, as well as the offer to developing countries to support them in adapting to achieve these objectives.
