Popis: Bioenergy with carbon capture and storage (BECCS) is gaining increasing attention not only as a carbon-neutral alternative to fossil fuels as an energy source, but also as one of the most cost-effective paths to achieve “negative emissions”, which aims at inducing a net emission reduction of atmospheric CO2 with the combined effect of photosynthesis and capture of CO2 emissions. However, like any solution to tackle environmental issues, BECCS has challenges and obstacles to overcome. Concerns over food security, land use, water use, and the feasibility of application at scale have notably been raised and addressing them will be crucial for successful implementation. As an emerging field, active research and development over the next decades, along with strong policy support, is crucial to ensure that BECCS can be implemented in time because delaying action on climate change reduces the likelihood of successfully meeting the goals of the Paris Agreement. Consequently, this critical review aims at establishing the upcoming challenges facing the implementation of BECCS and the pathways to address them, along with highlighting the advancements in the field over the last decade. An overview of the different paths to policy support along with techno-economic analyses of various forms of BECCS is also provided.
