Ecological Comparison of Renewable Energy Technologies with Other Options for Climate Protection
Various technologies for Carbon Capture and Storage (CCS) are discussed as options for the extended use of coal on the background of a more climate protection oriented energy system. The aim of the project is to evaluate the general feasibility (in ecological, economic and social terms) of CCS-technologies for sustainable future energy supply, and to assess appropriate reference systems and system configurations for the generation/production of electricity and hydrogen. These reference systems will be compared systematically with other climate protection options.
Leading questions of the analyses are:
What are the driving forces for CO2 capture and storage?
Which possible paths for CO2 capture and storage (technologies, infrastructures) are feasible and when will they be available for market introduction?
Which national and international storage potentials are available and which ecological restrictions have to be considered?
How can CCS be assessed in the context of life cycle analysis (LCA) compared to other options?
How do CCS technologies compare to other low or zero emissions options (based on criteria like costs, technological development, learning curves, ecological restrictions)?
Which contribution can CO2 capture and storage make for climate protection in comparison to other technological options - and in which time frame?
Could CCS be a bridge in the transition path to a solar energy system? Or are negative impacts dominant?
