BECCS-TAB

The BECCS-TAB project aims to develop comprehensive recommendations, practical frameworks and guidance for assessing CO₂ removal potentials by capturing and geologically storing CO₂ emissions from thermal waste treatment plants. The actual CO₂ removal potential depends on various technical and geo-technical parameters, as well as socio-political factors. The project will examine how these parameters and factors influence the removal potential using example scenarios.
Specifically, the project will identify which data and information are required for detailed accounting of all CO₂ streams associated with capturing, transporting and storing CO₂ emissions from thermal waste treatment plants. Additionally, the project will examine which concepts and metrological solutions allow quantitative measurement, monitoring and accounting of CO₂ and other greenhouse gas emissions in these processes. Particular attention will be paid to ensure metrological traceability, as well as to methods for distinguishing between biogenic and fossil CO₂ in the captured CO₂ stream. Life cycle assessments of the entire process chain will be conducted to enable reliable CO₂ balancing, as well as to identify and assess potential environmental impacts. To this end, methods must be developed to address and deal with unavoidable measurement uncertainties and data gaps.
To evaluate options for the local storage of CO₂ captured from thermal waste treatment plants (as a model case for smaller, decentralised emitters), 3D fluid-dynamic simulations are being conducted for generic storage scenarios. These simulations take into account alternative storage concepts, such as maximising the proportion of CO₂ stored in dissolved form.
To support political and societal discussions about CDR options, social perception and acceptance of this technical CDR approach is being assessed empirically. Building on this, strategies are developed for public engagement and for a targeted, knowledge-based preparation of (geo-)technical information material.
The project’s outcomes are intended to broaden the portfolio of technical solutions for achieving negative emissions. Additionally, the project aims to support the implementation of carbon capture and storage at existing thermal waste treatment plants in line with current legal and regulatory requirements.
