Abstract Closing the carbon‐, hydrogen‐, and nitrogen cycle with renewable electricity holds promises for mitigation of facing environment energy crisis, along continuing prosperity human society. Descriptors bridge gap between physicochemical factors electrocatalysts their boosted activity serve as guiding principles during rational design electrocatalysts. The optimal adsorption strength key intermediates is potentially accessed under tendentious guidelines proposed by indicators, such d‐band center, Δ G H , E O* coordination number (CN), bond length, etc. Here, in this review, a comprehensive summary recent advances achieved regarding descriptors that aims recycling C/H/N‐containing chemicals offered. review initiated providing necessity development efficient then physics behind center introduced.

Towards circular plastics within planetary boundaries

Nature Sustainability, Год журнала: 2023, Номер 6(5), С. 599 - 610

Опубликована: Март 6, 2023

Abstract The rapid growth of plastics production exacerbated the triple planetary crisis habitat loss, plastic pollution and greenhouse gas (GHG) emissions. Circular strategies have been proposed for to achieve net-zero GHG However, implications such circular on absolute sustainability not examined a scale. This study links bottom-up model covering both end-of-life treatment 90% global boundaries framework. Here we show that even circular, climate-optimal industry combining current recycling technologies with biomass utilization transgresses thresholds by up four times. improving rates at least 75% in combination CO 2 can lead scenario which comply their assigned safe operating space 2030. Although being key unquantified effect novel entities biosphere, enhanced cannot cope demand predicted until 2050. Therefore, achieving requires fundamental change our methods producing using plastics.

Low-carbon hydrogen is an essential element in the transition to net-zero emissions by 2050. Hydrogen production from biomass a promising bio-energy with carbon capture and storage (BECCS) scheme that could produce low-carbon generate dioxide removal (CDR) envisioned be required offset hard-to-abate emissions. Here, we design BECCS supply chain for quantify, at high spatial resolution, technical potential CDR Europe. We consider sustainable feedstocks have minimal impacts on food security biodiversity, namely agricultural residues waste. find this can up 12.5 Mtons of H2 per year (currently ∼10 are used Europe) remove 133 CO2 atmosphere (or 3% European total greenhouse gas emissions). then perform geospatial analysis quantify transportation distances between where located users, 20% within 25 km hard-to-electrify industries. conclude chains represent overlooked near-term opportunity hydrogen.

The cost of direct air capture and storage can be reduced via strategic deployment but is unlikely to fall below stated cost targets

One Earth, Год журнала: 2023, Номер 6(7), С. 899 - 917

Опубликована: Июль 1, 2023

Carbon dioxide removal (CDR) is necessary to minimize the impact of climate change by tackling hard-to-abate sectors and historical emissions. Direct air capture storage (DACS) an important CDR technology, but it remains unclear when how DACS can be economically viable. Here, we use a bottom-up engineering-economic model together with top-down technological learning projections calculate plant-level cost trajectories for four technologies. Our analysis demonstrates that costs these technologies plateau 2050 at around $100-600 t-CO2-1 mainly via capital reduction through aggressive deployment, still exceed optimistic targets defined countries such as US (i.e., $100 t-CO2-1). A further existing policy mechanisms indicates strong, project-catered support will required create market opportunities, accelerate scale-up lower further. work suggests strategic deployment operation must coupled strong policies minimise maximise opportunity make planet-scale impact.

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
