Film 1: "Research for Climate Protection" (Length 03:59)

"It is undisputed that human beings are affecting the global carbon cycle by emitting greenhouse gases such as carbon dioxide. ..." Fact is, that starting with the industrialization the atmospheric CO₂ concentration reached levels never attained in hundreds of thousands years. Why can CCS (Carbon Capture and Storage) - together with a decrease in energy demand, maximization of energy efficiency and the development of renewable energy - help to meet the challenge of minimizing global climate change?

Film 2: "Geological Conditions and Capacities" (Length 06:00)

"Porous rocks with good permeability have, in Germany and world-wide, the highest potential for geological CO₂ storage. ..." Where do these rocks occur? And which further criteria need potential CO₂ storage sites to meet?

Film 3: "Trapping Mechanism" (Length 04:31)

"... To achieve the reduction targets, the CO₂ has to remain permanently in the underground. For carefully selected storage locations no leakage is expected. ..." There are various natural trapping mechanisms that retain the CO₂ at different time scales. Which kind of mechanisms are there and how do they work?   

Film 4: "Monitoring and Prediction" (Length 06:54)

"The geological storage of CO₂ has a clear intention: The reduction of the greenhouse gas CO₂ produced by humanity." Because safety and the protection of humans and environment take top priority, comprehensive monitoring of CO₂ storage sites is required. Which kind of monitoring methods are available for CO₂ storage sites?

Film 5: "Ketzin Pilot Site" (Length 05:05)

"At the Ketzin pilot site in Brandenburg, Germany, CO₂ has been injected into an underground storage formation since June, 2008. ...". The monitoring methods used at the pilot site Ketzin are among the most comprehensive in the field of CO₂ storage worldwide. Important is the combination of different monitoring methods, each with different temporal and spatial resolutions. Which methods are used? And what have we already learned?

Film 6: "Scientific Drilling at the pilot site Ketzin"  (Length 08:53)

"At the pilot site Ketzin three wells were drilled to depths of 750 to 810 meters in 2007 before the start of CO₂ injection ..." In 2011 a fourth, and 2012, the fifth well was constructed. This last well (Ktzi 203) for the first time offers the unique opportunity to gain samples (cores) from a storage reservoir that have been exposed to CO₂ for more than four years. How were these samples (cores) gained and studied?
