This study critically evaluates a BECCS-Hub within the North-West Industrial Carbon Capture cluster using advanced digital twin modelling via the Carbon Navigation System and detailed biomass mapping. It investigates five distinct BECCS supply chains at the Protos site, each reflecting novel configurations that closely align with upcoming BECCS projects within the UK. This research highlights significant carbon performance and scalability variations, crucial for aligning with evolving BECCS business models. A key finding is the essential role of biomass security and adaptability in uncertain future biomass availability and heightened intra-BECCS competition. The study reveals potential gridlock scenarios where intense competition for biomass could severely limit the scalability and efficiency of BECCS operations, especially under high competition scenarios. These gridlocks could significantly hinder strategic BECCS deployments by constraining resource availability and complicating logistics, thus impacting the pursuit of the UK's Net-Zero goals. The findings underscore the need for diverse and adaptable deployment strategies that account for biomass availability, technological feasibility, and local infrastructure—factors pivotal to achieving scalable and efficient BECCS operations. Advocating a nuanced, integrated approach to managing biomass competition and optimise resource use, the paper calls for proactive strategic planning and adaptability in BECCS deployment. By leveraging modelling innovations, the study aligns BECCS operations with the UK's stringent Net-Zero objectives and specific business models for BECCS. Such an approach will enhance the sustainable and efficient deployment of BECCS technologies in a competitive and rapidly evolving energy landscape.
