Detailed analysis of decarbonisation pathways and technologies informs policy by highlighting the role of net-negative carbon emission technologies for hard-to-abate sectors and the importance of a diversified fuel mix in stabilising the energy system.
The Sargent Centre focuses on developing technologies, and systems-level solutions, to mitigate carbon emissions while ensuring energy affordability and security. Our work includes Carbon Capture and Storage (CCS), Bioenergy with Carbon Capture and Storage (BECCS). These technologies are essential for decarbonising hard-to-abate sectors such as cement, steel, and power generation. Professor Niall Mac Dowell’s research has been instrumental in demonstrating the potential of BECCS to not only reduce emissions but also achieve net-negative carbon outcomes by 2050. His work, often cited in key studies, highlights how BECCS can stabilise energy systems by addressing the intermittency challenges associated with renewable energy sources like wind and solar. Recent collaborative efforts with industry stakeholders, including Drax, have explored the application of BECCS in the United States, particularly in regions like California, the Midwest, and Texas.
Beyond technological advancements, the Centre has also developed frameworks for addressing the “energy trilemma,” which refers to the need to balance sustainability, affordability, and energy security. A recent publication in Cell Reports Sustainability demonstrates the integration of fuel mix diversification and reduced reliance on energy imports to create resilient and low-carbon energy systems. The Centre applied computational models to show that achieving energy security alongside decarbonisation targets is possible with only marginal cost increases. The Centre’s work continues to inform key stakeholders, offering data-driven recommendations to enhance the impact of decarbonisation policies in the UK and beyond. For instance, studies evaluating the role of CCS in achieving the UK’s net-zero targets have quantified its economic benefits and emissions reduction potential. The Sargent Centre continues to contribute to increasing awareness and acceptance of decarbonisation technologies. Its thought leadership extends to advising government bodies on Greenhouse Gas Removal (GGR) strategies, including input on policy design to align CCS and BECCS with national climate goals, engaging with public audiences through media outlets like The Guardian and participating in discussions at the Science Media Centre.
