وترى أطراف عديدة (كندا والمجموعة الأوروبية والنرويج وهولندا والولايات المتحدة واليابان) أن أحد الخيارات التكنولوجية وهو خيار واعد بصفة خاصة - يتمثل في استيعاب انبعاثات ثاني أكسيد الكربون من محطات التوليد بالفحم أو بالغاز وحبسها في هياكل جيولوجية - قد بات مؤخرا خيارا جديا على المدى المتوسط (الإطار 8).
Seismic monitoring suggests that the CO2 is permanently trapped below the impermeable cap layer overlying the reservoir. The United StatesUnited States reported on a large research and development budget aimed at reducing the cost of carbon sequestration and capture from energy production activities; establishing the technical, environmental, and economic feasibility of carbon sequestration using a variety of storage sites and fossil energy systems; determining the environmental acceptability of large-scale CO2 storage; and developing technologies that produce valuable commodities from CO2 reuse. The United StatesUnited States is also pursuing versions of the technology that would produce hydrogen for use in power generation or transport. Canada reported on several studies and pilot projects in this field, including the Weyburn project to assess the use of CO2 sequestration in enhanced oil recovery.
