IEA: Innovation needs in the Sustainable Development Scenario

“Innovation is central to the Sustainable Development Scenario. Almost 35% of the cumulative CO2 emissions reductions seen in the Sustainable Development Scenario by 2070 compared with the current trajectory come from technologies that are currently at the prototype or demonstration phase and that will not become available at scale without further R[&]D (including commercial demonstrators) and technical improvements.”

Power, Ian M.; et al. (2021): Carbonation, Cementation, and Stabilization of Ultramafic Mine Tailings

Power, Ian M.; Paulo, Carlos; Long, Hannah; Lockhart, Justin A.; Stubbs, Amanda R.; French, David; Caldwell, Robert (2021): Carbonation, Cementation, and Stabilization of Ultramafic Mine Tailings. In Environmental science [&] technology 55 (14), pp. 10056–10066. DOI: 10.1021/acs.est.1c01570.

“A promising approach for de-risking brucite-bearing ultramafic tailings is in situ cementation via carbon dioxide (CO2) mineralization, which also sequesters this greenhouse gas within carbonate minerals. In cylindrical test experiments, brucite [Mg(OH)2] carbonation was accelerated by coupling organic and inorganic carbon cycling. Waste organics generated CO2 concentrations similar to that of flue gas (up to 19%).”
