Beaver swallows CO2: new deadly weapon against greenhouse gases?

Denmark launched yesterday the world's first installation to remove carbon dioxide from fumes escaping from a coal-fired power plant. Perhaps a significant advance in the fight against greenhouse gases.

It happened on March 15, in Denmark, precisely on the site of the Esbjerg power plant. The event is important because it suggests a solution to help significantly reduce the greenhouse gas emissions that cause global warming. Inaugurated yesterday, Castor, an industrial pilot known as “CO2 capture”, conducted under the aegis of the IFP (French Petroleum Institute) and the European Commission, is quite simply the first installation making it possible to capture carbon dioxide from even the fumes from a thermal power plant to store it in the basement.

Objective: to bury 10% of CO2 produced in Europe

How to limit the volume of CO2 generated by industrial installations, such as cement plants, power plants or refineries? These would be responsible for more than 60% of global greenhouse gas emissions. The idea, for a long time on the bench, is to recover the gas where it is produced, that is to say directly in the offending factories, and reinject it into the basement before it is diffused into the atmosphere. This is the so-called "geological capture and storage" route: "the most promising" according to IFP.

But if on paper it is simple, in reality one runs in particular with problems of costs, which Castor seems to solve. This program, launched in 2004, brings together thirty partners coordinated by IFP to design by 2008 technologies to capture and store no less than 10% of CO2 emitted in Europe, 30% of emissions from large installations industrial.
