Industrial biochar systems for atmospheric carbon removal: a review

Abstract In the context of climate change, there is an urgent need for rapid and efficient methods to capture sequester carbon from atmosphere. For instance, production, use storage biochar are highly negative, resulting in estimated sequestration 0.3–2 Gt CO 2 year ?1 by 2050. Yet, production requires more knowledge on feedstocks, thermochemical conversion end applications. Herein, we review design development systems, investigate removal industry. Carbon efforts currently promoted via voluntary market. The major commercialized technologies offering atmospheric forestation, direct air utilization storage, soil sequestration, wooden building elements biochar, with corresponding fees ranging 10 895 GBP (British pounds) per ton . Biochar range 52 131 , which indicates that a realistic strategy can be deployed at large scale. services offered through robust marketplaces require extensive certification, verification monitoring, adds element credibility authenticity. eligibility dependent type feedstock utilized processing conditions employed. Process optimization imperative produce product meets application-specific requirements, environmental regulations achieve ultimate stability purposes.
