Achieving net-zero emissions in agriculture: a review

Environmental Research Letters, Год журнала: 2023, Номер 18(6), С. 063002 - 063002

Опубликована: Май 16, 2023

Abstract Agriculture accounts for 12% of global annual greenhouse gas (GHG) emissions (7.1 Gt CO 2 equivalent), primarily through non-CO emissions, namely methane (54%), nitrous oxide (28%), and carbon dioxide (18%). Thus, agriculture contributes significantly to climate change is impacted by its consequences. Here, we present a review technologies innovations reducing GHG in agriculture. These include decarbonizing on-farm energy use, adopting nitrogen fertilizers management technologies, alternative rice cultivation methods, feeding breeding enteric methane. Combined, all these measures can reduce agricultural up 45%. However, residual 3.8 equivalent per year will require offsets from removal make net-zero. Bioenergy with capture storage enhanced rock weathering are particularly promising techniques, as they be implemented within result permanent sequestration. While net-zero technically available, come price premium over the status quo have limited adoption. Further research development needed such more affordable scalable understand their synergies wider socio-environmental impacts. With support incentives, transition significant emitter sink. This study may serve blueprint identify areas where further investments accelerate

Functional Biochar Synergistic Solid/Liquid-Phase CO₂ Capture: A Review

Energy & Fuels, Год журнала: 2022, Номер 36(6), С. 2945 - 2970

Опубликована: Фев. 23, 2022

Nowadays, global warming is becoming more and serious, while CO2 capture technologies have emerged endlessly, with methods of solid-phase for physical adsorption liquid-phase chemical absorption. Biochar has been widely used to achieve sequestration emission reduction as a result its wide range precursor sources, strong adsorption, rich surface functional groups. It reviews the existing post-combustion solutions, focusing on analysis based ammonia/monoethanolamine carbon-based materials. The former (liquid phase) limitation efficiency volatility thermal degradation, latter (solid accompanied by limited CO2/N2 selectivity. realization synergy between two would "learn from each other's strengths" improve ability. review puts forward concept "biochar-functionalized cross-linking synergistic ammonia technology", which not only broadens idea multi-level utilization biochar, significantly improving (ammonia) efficiency, but also practical significance biomass waste emissions.

Potential of land-based climate change mitigation strategies on abandoned cropland

Communications Earth & Environment, Год журнала: 2023, Номер 4(1)

Опубликована: Фев. 16, 2023

Abstract Natural revegetation, afforestation, and lignocellulosic crops for bioenergy, possibly coupled with a developing technology like carbon capture storage, are the most common land-based climate change mitigation options. However, they can compete land threaten food security or nature conservation. Using abandoned cropland their deployment minimize these risks, but associated potentials unclear. Here, we compare alternative options by integrating historical future (up to 2050) site-specific biomass yields life-cycle emissions. Considering natural revegetation in biodiversity priority areas different measures remaining achieve potential of 0.8–4.0 GtCO 2 -equivalents yr −1 (2–11% 2021 global CO emissions). Afforestation generally provides larger benefits than bioenergy storage delivers highest locations. Overall, results offer refined estimates from highlight opportunities context-specific measures.

Cation Vacancy Modulated Interfacial Electronic Interactions for Enhanced Electrocatalysis in Lithium–Oxygen Batteries

Advanced Functional Materials, Год журнала: 2024, Номер 34(27)

Abstract Li–O 2 batteries deliver ultrahigh theoretical specific energy while suffering from low efficiency and poor cyclability due to sluggish kinetics of oxygen electrode reactions. Herein, a strategy engineering interfacial electron structure MXene‐based composites is presented boost reactions for advancing with the cation vacancy‐rich CoSe@MXene (V Co ‐CoSe @MXene) as case study. The formation Co─C bond between V Ti 3 C MXene its enhanced covalency after introducing vacancy leads promoted transfer CoSe optimized electronic sites, especially second sites neighboring vacancy, which serve active centers redox On this basis, @MXene‐based Li─O exhibit overpotential (0.35 V) excellent cycling stability (250 cycles at 500 mA g −1 ). This work proposes an effective develop electrocatalysts by tailoring structure.

Environmental impacts of carbon capture, transport, and storage supply chains: Status and the way forward

International journal of greenhouse gas control, Год журнала: 2024, Номер 132, С. 104039 - 104039

Опубликована: Янв. 2, 2024

Carbon capture, transport, and storage (CCTS) enables the decarbonization of industrial emitters. CCTS is regarded as crucial in reaching net-zero emission targets but currently stands far behind required scale. deployment for point sources may be accelerated by chains relying on available technology, called pioneering supply chains. In particular, transporting CO2 standard containers can implemented without new transport infrastructure. Pioneering must not cause more emissions than they store to successfully avoid emissions. Using life cycle assessment, we show that emit less permanently, demonstrating already today 50 70% source GHG This evidence proves robust against uncertainties based scarce operational experience CCTS. Our environmental assessment shows increasing capture rate above assumed 90% a main lever increase avoidance 80%. Capturing causes large shares chain's global warming impact rely fossil fuels. Reducing intensity energy switching pipeline-based reduce other impacts compared analysis accelerate infrastructure scale-up while storing from sources.

Integrating Carbon Dioxide Removal Into European Emissions Trading

Frontiers in Climate, Год журнала: 2021, Номер 3

Опубликована: Июнь 24, 2021

In one of the central scenarios for meeting an European Union-wide net zero greenhouse gas (GHG) emissions target by 2050, cap in Union Emissions Trading System (EU ETS) becomes negative. Despite this ambition, no mechanism allows inclusion CO 2 removal credits (CRCs) EU ETS to date. Amending legislation is required create enabling conditions a negative cap. Here, we conceptually discuss various economic, legal, and political challenges surrounding integration CRCs into ETS. To analyze cap-and-trade systems encompassing emissions, introduce effective (elastic) resulting from addition regulatory (inelastic) cap, latter now being binding only. Given current cost estimates BECCS DACCS, minimum quantities use removals, as opposed ceilings currently discussed, would be promote near-term such technologies. Instead direct interaction between companies involved trading providers CRCs, authority could also transitionally act intermediary buying supplying them turn conditional upon observed allowances prices, example, supporting (soft) price collar. Contrary collar without dedicated support case (net) compliance with overall maintained. already provides safeguards physical carbon leakage concerning CCS, making Bioenergy Carbon Capture Storage (BECCS) Direct Air prioritized Furthermore, special opportunity might apply installations. Repealing provision that installations exclusively using biomass are not covered Directive, combined freely allocated these installations, allow operators sell made available through BECCS. Achieving GHG neutrality 2050 requires designing suitable incentive removal, which includes option open up CRCs.
