Capturing and storing CO2: Five technologies on the way to net zero
If Switzerland wants to achieve its goal of zero net greenhouse gas emissions by 2050, it will have to rely on the use of negative emission technologies (NET), i.e. processes that remove CO2 from the atmosphere and store it for the long term. Although NETs can - in principle - help achieve climate targets, much is still unclear at present. This is because some of these processes are still untested in practice, technically complex, costly or cannot be used on a large scale for the time being. In addition, many people know little about both the possibilities and the limitations of NET. On behalf of TA-SWISS, researchers from the Öko-Institut and Empa therefore evaluated five NETs that are relevant for Switzerland, with the involvement of other experts. The results showed that a single process is not sufficient; all NETs are needed. In addition, the reduction of CO2 emissions must remain central. After all, it is cheaper to avoid emissions than to subsequently remove CO2 from the air.

Gallen und Thun, 28.04.2023 - If Switzerland wants to achieve its goal of zero net greenhouse gas emissions by 2050, it will have to rely on the use of negative emission technologies (NET), i.e. processes that remove CO2 from the atmosphere and store it for the long term.
Although NETs can - in principle - help achieve climate targets, much is still unclear at present. This is because some of these processes are still untested in practice, technically complex, costly or cannot be used on a large scale for the time being.
In addition, many people know little about both the possibilities and the limitations of NET. On behalf of TA-SWISS, researchers from the Öko-Institut and Empa therefore evaluated five NETs that are relevant for Switzerland, with the involvement of other experts.
The results showed that a single process is not sufficient; all NETs are needed. In addition, the reduction of CO2 emissions must remain central.
After all, it is cheaper to avoid emissions than to subsequently remove CO2 from the air. The TA-Swiss study aims to inform politicians and the public about the opportunities, limits and risks of various methods for CO2 removal and storage.
Aspects such as feasibility, climate effectiveness, costs, resource consumption and impact on the environment and population were considered.The five technologies are:Claudia SomTechnology and SocietyTel. +41 58 765 78 43claudia.som@empa.chDr.
