“…The CO 2 stream produced from the decarbonation cell may also have value in applications that up-cycle captured CO 2 . CO 2 is already used to enhance oil recovery (EOR) (63,64) and to make chemicals such as urea, salicylic acid, methanol, carbonates (65), synthetic fuel (via the Fischer-Tropsch process) (66), and synthetic natural gas (via the Sabatier reaction) (67). There is growing interest in finding ways to react CO 2 electrochemically or photochemically to create chemicals and fuels from captured CO 2 using renewable electricity (68).…”

Cement production is currently the largest single industrial emitter of CO2, accounting for ∼8% (2.8 Gtons/y) of global CO2emissions. Deep decarbonization of cement manufacturing will require remediation of both the CO2emissions due to the decomposition of CaCO3to CaO and that due to combustion of fossil fuels (primarily coal) in calcining (∼900 °C) and sintering (∼1,450 °C). Here, we demonstrate an electrochemical process that uses neutral water electrolysis to produce a pH gradient in which CaCO3is decarbonated at low pH and Ca(OH)2is precipitated at high pH, concurrently producing a high-purity O2/CO2gas mixture (1:2 molar ratio at stoichiometric operation) at the anode and H2at the cathode. We show that the solid Ca(OH)2product readily decomposes and reacts with SiO2to form alite, the majority cementitious phase in Portland cement. Electrochemical calcination produces concentrated gas streams from which CO2may be readily separated and sequestered, H2and/or O2may be used to generate electric power via fuel cells or combustors, O2may be used as a component of oxyfuel in the cement kiln to improve efficiency and lower CO2emissions, or the output gases may be used for other value-added processes such as liquid fuel production. Analysis shows that if the hydrogen produced by the reactor were combusted to heat the high-temperature kiln, the electrochemical cement process could be powered solely by renewable electricity.

“…Today CO 2 -EOR has the potential to sequester 30 GtCO 2 if the CO 2 used in oil recovery [assuming an industry standard of 3 bbl oil per tCO 2 sequestered] is left in the ground after oil production (Kuuskraa, 2013;International Energy Agency, 2015). Advanced CO 2 -EOR methods, designed to co-optimize both oil recovery and CO 2 sequestration, could sequester over 90 GtCO 2 (National Academies of Sciences Engineering Medicine, 2019), and this could increase oil production compared to standard CO 2 -EOR methods (Benson and Deutch, 2018).…”

“…Our model results, along with CO 2 reduction costeffectiveness, do not represent full benefit-cost analyses of individual projects. Ideally, a full benefit-cost analysis for an individual project would include: site specific generation profiles and detailed electrical dispatch model runs for RE; full health benefits and impacts of emissions changes from coal with CCS [39,46,47]; full life cycle impacts for fossil fuel use changes, including increases in the case of coal with CCS [39,[48][49][50]; impacts of captured CO 2 , especially if it is used for enhanced oil recovery [45,51]; electricity price effects [52,53], and impacts from RE manufacture and installation [54][55][56][57].…”

The type, size, and location of renewable energy (RE) deployment dramatically affects benefits to climate and health. Here, we develop a ten-region model to assess the magnitude of health and climate benefits across the US We then use this model to assess the benefits of deploying varying capacities of wind, utility-scale solar photovoltaics (PV), and rooftop solar PV in different regions in the US-a total of 284 different scenarios. Total benefits ranged from $2.2 trillion for 3000 MW of wind in the Upper Midwest to $4.2 million for 100 MW of wind in California. Total benefits and highest cost effectiveness for CO 2 reduction were generally highest for RE deployment in the Upper Midwest and Great Lakes and Mid-Atlantic US and lowest in California. Health was a substantial portion of total benefits in nearly all regions of the US Benefits were sensitive to methane leakage throughout the gas supply chain.
