Coastal enhanced weathering (CEW) is a carbon dioxide removal (CDR) approach whereby crushed silicate minerals are spread in coastal zones to be naturally weathered by waves and tidal currents, releasing alkalinity removing atmospheric (CO2). Olivine has been proposed as candidate mineral due its abundance high CO2 uptake potential. A life cycle assessment (LCA) of silt-sized (10 μm) olivine revealed that CEW's life-cycle emissions total environmental footprint, i.e., penalty, amount around 51 kg CO2eq 3.2 Ecopoint (Pt) units per tonne captured CO2, respectively, these will recaptured within few months. Smaller particle sizes dissolve even faster; however, their footprints (e.g., 223 10.6 Pt tCO2–1, for 1 μm olivine), engineering challenges comminution transportation, possible stresses airborne and/or silt pollution) might restrict applicability. Alternatively, larger exhibit lower 14.2 tCO2–1 1.6 1000 olivine) could incorporated zone management schemes, thus possibly crediting CEW with avoided emissions. However, they much slower, requiring 5 37 years before the becomes net negative, respectively. The differences between penalties highlight need using multi-issue impact methods rather than focusing on balances alone. When full profile was considered, it identified fossil fuel-dependent electricity main hotspot, followed nickel releases, which may have large marine ecotoxicity. Results were also sensitive transportation means distance. Renewable energy low-nickel can minimize profile.

In circular economies, it is imperative to implement effective environmental management solutions address resource depletion. Over the past few years, there has been a growing recognition of potential agricultural crop waste in mitigating greenhouse gas (GHG) emissions and promoting global carbon neutrality. Despite lacking practical options, open-field burning residue contributes significantly air pollution. This challenge may be addressed by producing biochar through pyrolysis residues. A application agriculture can contribute reducing warming sequestration atmospheric from soil. As part life cycle assessment biochar, yield during its production are critical factors, which emphasize importance selecting method suitable for biochar. The objective this paper present comprehensive overview agronomic advantages associated with along detailed analysis (LCA). Furthermore, provides an how facilitate local energy sustainable within nexus agroecosystems, environment, energy.

Abstract. Ocean alkalinity enhancement (OAE) is an emerging strategy that aims to mitigate climate change by increasing the of seawater. This approach involves ocean enhance its capacity absorb and store carbon dioxide (CO2) from atmosphere. chapter presents overview technical aspects associated with full range OAE methods being pursued discusses implications for undertaking research on these approaches. Various have been developed implement OAE, including direct injection alkaline liquid into surface ocean; dispersal particles ships, platforms, or pipes; addition minerals coastal environments; electrochemical removal acid Each method has advantages challenges, such as scalability, cost effectiveness, potential environmental impacts. The choice technique may depend factors regional oceanographic conditions, source availability, engineering feasibility. considers methods, accelerated weathering limestone, liming, creation hydrated carbonates, environments. In each case, technologies are considered, best-practice drawn. social impacts will likely specific technology local context in which it deployed. Therefore, essential feasibility undertaken parallel with, informed by, wider impact assessments. While shows promise a mitigation strategy, acknowledge limitations uncertainties. Further development needed understand long-term effects, optimize techniques, address unintended consequences. should be viewed complementary extensive emission reductions, improved if operated using energy supply chains minimal CO2 emissions.

Currently, scientists and investors consider Direct Air Capture (DAC) as one of the candidates to reduce CO2 emissions. The emissions cut is pressing since 30% (i.e., 20 GtCO2/y) current greenhouse gas must be addressed by 2030. In seven years, removal (CDR) technologies are expected reach a Technology Readiness Level (TRL), relevant industrial applications. most promising at TRL-7, but jump TRL-11 in new IEA scale for disruptive looks unlikely because scale-up from small pilots requires time large investments. Moreover, validation on still missing or even unplanned. This work also identifies critical materials supply chain competition with energy transition limiting factors which could further hinder DAC deployment contribution next years when first significant should addressed.

Abstract Hydrogen will play a key role in decarbonizing economies. Here, we quantify the costs and environmental impacts of possible large-scale hydrogen economies, using four prospective demand scenarios for 2050 ranging from 111–614 megatonne H 2 year −1 . Our findings confirm that renewable (solar photovoltaic wind) electrolytic production generates at least 50–90% fewer greenhouse gas emissions than fossil-fuel-based counterparts without carbon capture storage. However, could still result considerable burdens, which requires reassessing concept green hydrogen. global analysis highlights few salient points: (i) mismatch between economical across continents seems likely; (ii) region-specific limitations are inevitable since possibly more 60% large potentials concentrated water-scarce regions; (iii) upscaling be limited by power generation natural resource potentials.

Abstract The current centralized configuration of the ammonia industry makes production nitrogen fertilizers susceptible to volatility fossil fuel prices and involves complex supply chains with long-distance transport costs. An alternative consists on-site decentralized using small modular technologies, such as electric Haber–Bosch or electrocatalytic reduction. Here we evaluate cost-competitiveness producing low-carbon at farm scale, from a solar agrivoltaic system, electricity grid, within novel global fertilizer industry. Projected costs for are compared historical market production. We find that relies on chain disruptions. Taking both factors into account, could achieve up 96% demand by 2030. These results show potential technologies in revolutionizing industry, particularly regions facing food insecurity.
