Global warming is one of the biggest issues of our time. To meet the targets set for reducing CO2 emissions, it's widely accepted that new technology will play an important role sometimes as a "bridging technology"- while alternative sustainable energy sources are being developed. One of the most promising technologies is Carbon Capture and Storage (CCS). This a means of capturing CO2 from sources such as power plants, compressing the CO2 and storing it away safely in geological formations underground or under the seabed instead of releasing it into the atmosphere. The video report shows: A CCS project under construction at a lignite power plant run by the energy company Vattenfall at Schwarze Pumpe, south of Berlin, An EU backed carbon storage project at Ketzin in Germany, A North Sea oil field run by the Norwegian company Statoil which was the first place in the world to begin CCS on a commercial basis, How both the EU and the US are working hard to develop the Carbon Capture and Storage technology. Interviews with key figures including: Staffan Görtz, Vattenfall Professor Frank Schilling GFZ National Research Centre for Geo-Sciences Matti Vainio, Energy & Environment Unit, DG Environment, European Commission Boyden Gray, US Ambassador to the EU Arve Thorvik Statoil, Statoil Sleipner West gas rig

When the Schwarzer Pumper power plant was built south of Berlin in 1998, 00:00:00
it was the biggest lignite-fired power plant in the world. 00:00:05
It provides electricity for 2 million households in Germany, 00:00:08
but in the process spews out 10 million tons of carbon dioxide every year. 00:00:12
CO2 from burning fossil fuel plays a major role in warming the Earth's temperature. 00:00:17
An increase in carbon dioxide in the air prevents heat escaping into space. 00:00:22
Instead, it warms up the planet. 00:00:27
So what would happen if this carbon dioxide could be somehow captured 00:00:30
before it could escape to do its damage to the environment? 00:00:34
That's exactly what engineers and scientists from the Vattenfall Energy Company are planning to do 00:00:37
with what's known as carbon capture and storage. 00:00:42
Carbon capture and storage is an idea of capturing carbon dioxide from a coal-fired power plant, 00:00:46
transport it and safely store it deep underground. 00:00:51
The idea of storing carbon dioxide underground was born from the knowledge 00:00:54
that this kind of formation has been able to store natural gas and oil for millions of years. 00:00:59
And that was how it was born. And we know today that we can do this safely. 00:01:06
Vattenfall is building a small-scale experimental power plant at Schwarzer Pumper, 00:01:10
which will be CO2-free. 00:01:15
The carbon emissions will be captured while the coal is being burnt. 00:01:17
In a process called oxyfuel combustion, oxygen rather than air is used 00:01:21
during the burning of the lignite or brown coal. 00:01:25
This produces flue gases made up of steam and a high concentration of carbon dioxide. 00:01:28
