CCSliknande

CCS-liknande is a term used in climate policy and research, particularly in Swedish-language sources, to describe approaches that resemble carbon capture and storage (CCS) in their aim of reducing atmospheric CO2. It denotes a category of strategies that capture carbon and result in its removal from the atmosphere or from emissions, with the captured carbon subsequently stored or otherwise kept from re-entering the carbon cycle. It is not a single technology, but a set of related concepts and methods.

Examples discussed under CCS-liknande include bioenergy with carbon capture and storage (BECCS), direct air capture with storage (DACCS), mineral carbonation, and other long-term disposal or utilization pathways such as permanent materials that lock in carbon. Some proposals emphasize capture at the source (point-source capture), while others focus on atmospheric removal. The permanence and verifiability of storage, the scales required, and the energy and cost requirements vary across approaches.

While CCS-liknande approaches offer potential negative emissions and complement decarbonization, they face significant challenges. Questions remain about long-term storage security, additionality, baselines, monitoring, regulatory frameworks, and public acceptance. The term reflects the recognition that several near-term and long-term options operate alongside conventional CCS and may require different governance, accounting, and risk-management considerations.

Related topics include carbon capture and storage (CCS), carbon capture, utilization and storage (CCUS), and broader discussions of negative emissions technologies.
