Finding out the needs of cities and their inhabitants is an essential part of today’s climate challenges and investigations. Through accurate research and appliance of modern and suitable methods, the scientific community is actively acting to address the main current issues of climate change and the proposed solutions to tackle environmental concerns. The goal is to stimulate and facilitate sustainable urban development resilient to the impacts of climate change.

Collaboration between different sectors is essential for managing and researching the challenging field of climate change. The ACCSESS project, “Providing access to cost-efficient, replicable, safe and flexible CCUS”, aims to increment the awareness about the urgency of climate change and promote science-based solutions, founded by Carbon Capture, Utilization and Storage, which is a new technology that can help mitigate the effects of climate change. ACCSESS is investigating the potential of Carbon Capture and Storage to enhance urban sustainability. 

The study takes an exhaustive approach, examining the social and governance implications of Carbon Capture and Storage. The research employs various methods, including interviews, surveys, social media analysis, workshops, educational material development and stakeholder engagement. Fraunhofer IAO is responsible for carrying out the following parts of the project among other tasks:

  • Report on citizens' acceptance and concerns: Surveys and sentiment analysis on social media data are implemented to gather insights on public opinion regarding Carbon Capture and Storage and its concerns. The information collected is used to create educational materials on the pros and cons of Carbon Capture and Storage.
  • Neutral solution packages for replication: Extensive research is being conducted to develop user-friendly information packages that will assist cities in adopting and replicating Carbon Capture and Storage solutions that are effective in various situations.
  • Carbon Capture and Storage Handbook for Sustainable Urban Development: This handbook aims to explain how Carbon Capture and Storage can contribute to the sustainability of cities. The handbook will first examine the strategies that cities are currently using to combat climate change, before outlining the role of Carbon Capture and Storage. In order to achieve that, two surveys targeting city administrations and a deep research and collection of contact information based on web scraping methods is applied. It is hoped that this guide will assist cities in making informed decisions about the implementation of Carbon Capture and Storage. In addition, the handbook aims to enable the creation of a visual geo-information system (GIS) map containing information about the current stand of development of CCUS in different cities around Europe, facilitating knowledge exchange and cooperation. 

The upcoming project phases are very promising with several actions to be implemented. We will keep you informed of any further updates on the collaboration! If you have any questions, please do not hesitate to contact us using the provided contact form.

The Project

ACCSESS is an EU Horizon2020 Innovation Action project with a total duration of four years: May 2021 - April 2025. The main coordinator is SINTEF Energy. 

The central objectives of the project are: 

  • Test CO2 capture and CO2 use at TRL7 and integrate capture technologies in industrial installations. 
  • Develop and improve CCUS chains from continental Europe and the Baltic area to the North Sea. 
  • Engage and inform stakeholders about CCUS and explain its societal benefits at large and for sustainable cities.

The project is a significant initiative focused on advancing Carbon Capture, Utilization, and Storage (CCUS) technologies in Europe. One of the primary goals of the project is to settle a standard methodology for CCUS chain development that integrates techno-economic and environmental analyses. This methodology targets the design cost-effective and environmentally friendly CCUS chains that can serve intersectoral networks. Additionally, the project aims to deliver an open-source tool for CCUS chain development, identify efficient and safe CO2 transport solutions with potential cost reductions, and integrate CO2 loading and offloading procedures along the CCUS chain.

Moreover, the ACCSESS project accentuates its commitment to reducing carbon footprints in urban areas, contributing to global efforts for net CO2 removal, and highlighting the positive climate impact of its activities. Pilot plant demonstrations for various CO2 capture technologies are also planned as part of the project's efforts to advance CCUS solutions and promote sustainability in the energy sector.


ACCSESS and Fraunhofer IAO


Fraunhofer IAO, as part of the ACCSESS project, is in charge of a wide variety of tasks framed in work package 12, Societal Integration of CCUS. The objectives of the work package are:

Develop educational materials targeting diverse stakeholders to elucidate CCUS benefits.

  • Create standardized CCUS solutions and a handbook for sustainable city development.
  • Provide training to national environmental authorities in Sweden and Germany on regulating CO2 capture installations.
  • Execute a comprehensive communication plan, organize workshops and events, and produce synthesis reports to enhance project visibility and stakeholder engagement.

For that, it is first necessary to capture the general public opinion about Carbon Capture using citizen surveys, social media and sentiment analysis. After that, and being analysed the results, the next step is to obtain and analyse Carbon Capture knowledge and development state in Europe. With that information, the ACCSESS consortium is able to create effective educational materials, the handbook for sustainable city development, training guidelines and methodologies, and workshops and events for stakeholders.

Would you like to participate?

Our ambition in ACCSESS is to help the society understand the benefits of Carbon Capture, together with enabling real access to cost-efficient, replicable, safe and flexible Carbon Capture, Utilization and storage. This demands an in-depth work, exchange of knowledge and collaboration between partners, citizens and public administrations.

We are currently seeking European cities willing to participate in two short surveys. The surveys aim to provide an overview of the current state of knowledge and development of Carbon Capture technologies in Europe, as well as promote a simple tool to encourage knowledge exchange between city administrations. Your cooperation would be greatly appreciated. It will aid in the development of our Carbon Capture and Storage Handbook for Sustainable Urban Development, as well as educational materials to bring Carbon Capture closer to public administrations and the general population in our continent.

For this or other issues, if you are an interested citizen, a public administration representative or a private company delegate, please do not hesitate to contact us using the form below. We look forward to hearing from you!
