Résumé : For France, a first analysis, based on current emissions from electricity generation in addition to concentrated industrial, energy related and non-energy-related emissions (such as decarbonisation), set the following magnitudes: approximately 75 million tonnes of CO2 per year are potentially concerned by CCS, i.e. approximately 19% of all CO2 emissions in France assessed to equal 395 million tonnes (excluding land use, land-use change and forestry). A technico-economic and environmental assessment has demonstrated that by the year 2050 CO2 storage applied to concentrated CO2 sources (ammonia production plants, etc.) and fixed sources emitting more than 0.9 MtCO2/year could lead to a reduction in these sectors of 33 to 54% of emissions, according to the number of industrial areas involved (Lorraine, Lower Seine, Paris region, Nord-Pas-de-Calais, Provence-Alpes-Côte d'Azur). In order to achieve the factor 4 objective in the French industrial sector by 2050, CCS technology must be implemented as of 2020. According to this hypothesis, storage sites must be made available, accounting for a cumulated volume between 2020 and 2050 of 1 billion tonnes of CO2.
In addition to geological storage, however for much smaller quantities, CO2 may be used as into a raw material. It is already used today in the agri-food industry for preserving foods (dry ice) or fizzy drinks. It is used in industry, for example as a reagent in the chemical industry, for industrial applications (coolants, solvents, etc.) or for EOR/EGR (Enhanced Oil/Gas Recovery). In 2008, approximately 150 million tonnes of CO2 were used throughout the world (40 million tonnes of which were injected annually for enhanced oil recovery). This represents 0.5% of all annual anthropogenic CO2 emissions.The main issue in using CO2 consists in finding new applications based on breakthrough technology thus increasing the volumes involved.
When transformed, CO2 is either definitively stored (e.g.: plastic manufacture) or stored for a set period of time (e.g.: biofuel manufacture). The CO2 emitted when using the product created from the transformation activity must therefore be taken into account, for example via LCAs - life cycle analyses - if available, in order to reason in terms of "CO2 saved").
This roadmap also considers the environmental and health impacts created by this entire industry and integrates the socioeconomic issues accompanying the emergence and large-scale deployment of CO2 capture, transport, storage and re-use.
A French version is available.
