BECCUS and flexible bioenergy – finding the balance

Contribution of IEA Bioenergy Task 44 & Task 40 to the Inter-task project Deployment of BECCUS value chains

In this system study, the two important technologies flexible bioenergy and BECCS (bioenergy with carbon capture and storage) are in focus. Both are expected to play a crucial role in mitigating climate change (compare IEA Net Zero by 2050 roadmap, IEA 2021). Combining CCU and CCS with a flexible operation of bioenergy facilities is possible from a technological point of view. The current business models for a flexible operation is mainly based on the electricity market prices and/or a possible incentive schemes supporting a flexible operation. Broader climate policy instruments and corresponding incentive schemes, however, are not in place (yet). The currently core business model for operating CCU is the market price realised for selling the carbon for use in other applications. Here, a constant CO 2 capture rate could be required to run reliable CO 2 -utilization concepts and business models. As the business models for the provision of flexible bioenergy and BECCS/U are of different nature, it has to be governed which role each of the technologies are going to play within the energy system and further within climate policy making. In particular, the implications of the interaction of both technologies should be considered and taken into account.
