Carbon dioxide capture and storage (CCS) is being researched as promising technology to reduce CO2 emissions while allowing fossil fuel use. CCS can play a key role on decarbonizing the energy and industrial sector, and act as a bridging technology towards renewable and sustainable energy future.

Also, the use of captured CO2 as feedstock (Carbon capture and utilization – CCU) for conversion to fuels and chemicals has increasingly gained attention. CCU is considered to have the potential to provide moderate revenue for CCS project development.


Analysis and understanding of the potential environmental benefits and trade-offs is fundamental for the development of carbon capture and storage (CCS) and carbon capture and utilization (CCU) as part of a sustainable system. Differences in key assumptions and system boundaries in environmental assessments of CCS published in the literature provide results varying on large ranges and even in the direction of the impacts (positive vs. negative). Assessment studies on CCU are yet lacking.

It is necessary that such information is available in a systematic and harmonized way so that breakthrough options that maximize environmental benefits along the chain can be further developed, and potential adverse impacts on the environment are identified at an early stage.


The main objective of this project was to develop and apply an integrated systematic approach to assess the life cycle environmental performance of novel CO2 capture storage and utilization technologies (CCS & CCU).

EDDiCCUT provides results on:

  • Assessment of the environmental performance of 10 representative case studies.
  • Development of an integrated approach for assessment based on technical, economic and environmental assessment methods.
  • Development of approaches to deal with uncertainties in data and knowledge base.
  • Documentation of approaches on how to consistently perform environmental due diligence of CCS and CCU technologies.

Value added

The results generated in the project provide knowledge and procedures to support R&D investment, policy decisions and priorities. 

EDDiCCUT results:

  • Will strengthen the basis for strategic environmental decision making.
  • Will provide a framework to benchmark/compare CCS and CCU options compatible with technology qualification procedures.
  • Will help identify routes & decisions to optimize environmental performance.
  • Better knowledge so generated will lead to better deployment strategies.
