Adánez-Rubio, I.; Pérez-Astray, A.; Abad, A.; Gayán, P.; Diego, L. de; Adánez, J. (2019): Chemical looping with oxygen uncoupling. An advanced biomass combustion technology to avoid CO2 emissions. In: Mitig Adapt Strat Glob Change 6, S. 189. DOI: 10.1007/s11027-019-9840-5.

"Bioenergy with carbon dioxide (CO₂) capture and storage (BECCS) technologies represent an interesting option to reach negative carbon emissions, which implies the removal of CO₂ already emitted to the atmosphere. Chemical looping combustion (CLC) with biomass can be considered as a promising BECCS technology since CLC has low cost and energy penalty. In CLC, the oxygen needed for combustion is supplied by a solid oxygen carrier circulating between the fuel and air reactors."

"This chapter gives a brief overview of the emergence of the idea of negative emissions technologies and solar radiation management technologies in climate change policy and the normative issues—questions of values—that they might raise. Normative issues fall into four broad categories: (1) distributive justice, (2) procedural justice, (3) ethical issues, and (4) rectificatory justice."

"Rapid formation of stable soil carbonates offers a potential biologically-mediated strategy for removing atmospheric CO₂ and forms a part of the negative emissions debate in a bid to maintain global temperatures of 1.5 °C. Microbial respiration in soil and respiration by plant roots leads to high partial pressure of CO₂ below ground.Given adequate supply of calcium in soil solution the sequestration of C into the mineral calcite (CaCO₃) can occur at rapid rates. We have coupled an established soil C model RothC to a simplified geochemical model so that this strategy can be explored and assessed by simulation."

"The United Nations, in the IPCC Special Report on Global Warming of 1.5ºC has accepted that there isn’t any obvious pathway to zero emissions in such a short time frame, so they have pegged their hopes on NETs – Negative Emissions Technologies. These approaches include carbon capture and storage (CCS), which involves sucking CO₂ from the air and storing it deep underground."
