Publications

This case study report presents the latest developments regarding the Hafslund Celsio full-scale CCS project at their Klemetsrud Waste to Energy (WtE) plant in Oslo, Norway. The project has been initiated in 2015 and went through different stages of project realisation since then. The purpose of this report is to present the different stages and challenges and to derive lessons learnt of developing this kind of BECCS project.

This report by Task 36 (Material and Energy Valorisation of Waste in a Circular Economy) presents the developments over the past 4 years by presenting the events in a chronological order. This helps to understand what it takes to implement first-of-its-kind BECCUS projects. The early stages of the Osloc CCS project have been described in previous reports of the BECCUS inter task project. 

The first-of-its-kind full-scale CCS project at a WtE plant has progressed despite numerous challenges, thanks to the commitment of those involved. Key lessons learnt include the importance of perseverance, patience, and thorough evaluation. Infrastructure and organizational needs are often underestimated. Especially the provision of electricity, transport, the significant need for space (especially challenging in urban settings) and a temporary storage at the harbour. Political or societal resistance may arise. Integrating new systems into existing operations proves to be complex, and managing various levels of process maturity is challenging. In the particular case on hand a bold cost-cutting phase helped to revitalize the project. From the above it has to be noted that some of the challenges encountered are not inherent to BECCUS projects however can apply in general when developing a new project.

About the BECCUS project

Within IEA Bioenergy TCP the topic of Bioenergy Carbon Capture, Usage and Storage is investigated with the involvement of many working Groups (Tasks), in an integral project of strategic relevance. In the years 2019-2021 the ‘Deployment of BECCUS value chains’-project was executed to understand the opportunities for, and obstacles to, deployment of BECCUs in different sectors. The project focused on determining factors for successful deployment, such as technology readiness levels, business model validities and designs of policy and regulatory framework.

In the second phase, the ‘BECCUS 2’-project is more diverse in scope, with stronger emphasis on cross-sector and cross-country learning about the implementation of BECCUS projects , using different energy conversion processes. The project also explores the effects of integrating BECCUSS facilities and systems within the overall energy system and, last but not least assesses the important differences between utilisation of captured carbon and storage of capture carbon.
