The co-benefits of integrating carbon dioxide removal in the energy system: A review from the prism of natural climate solutions

Par Sophie CHLELA & Sandrine SELOSSE

Abstract : Anthropogenic activities such as fossil fuel combustion and land use changes are increasing atmospheric CO2 concentrations, driving climate change. These emissions are distributed across three natural reservoirs: the atmosphere, land, and oceans. Climate change mitigation necessitates rapid reductions in greenhouse gas emissions and the removal of residual atmospheric CO2. However, among the solutions, Carbon Dioxide Removal (CDR) methods—especially Natural Climate Solutions (NCS)—are gaining attention. In this review, we explore how the energy system, a major contributor to climate change, can integrate these solutions. Thus, we present different CDR highlighting the role of NCS while determining their link to the energy system using biomass as renewable energy source through Bioenergy Carbon Capture and Storage. Hence, we schematized the pathways which depict their multiple roles like providing negative emissions A comparative evaluation of CDR methods identifies the affected components of ecosystems and energy systems. Additionally, this paper emphasizes that NCS not only eliminates carbon but also offers ecosystem benefits, such as enhanced biodiversity and agricultural productivity, while contributing to climate adaptation. The challenges, including land-use constraints and long-term sustainability, are underscored as critical to maximizing the effectiveness of CDR, which remains essential for achieving climate mitigation goals.
