Deployment expectations of multi-gigatonne scale carbon removal could have adverse impacts on Asia’s energy-water-land nexus

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: July 27, 2024

Abstract Existing studies indicate that future global carbon dioxide (CO 2 ) removal (CDR) efforts could largely be concentrated in Asia. However, there is limited understanding of how individual Asian countries and regions will respond to varying uncertain scales CDR concerning their energy-land-water system. We address this gap by modeling various levels CDR-reliant pathways under climate change ambitions find high reliance leads residual fossil fuel industry emissions about 8 Gigatonnes CO yr −1 (GtCO 2050, compared less than 1 GtCO moderate-to-low reliance. Moreover, expectations multi-gigatonne delay the achievement domestic net zero for several regions, lead higher land allocation fertilizer demand bioenergy crop cultivation. Here, we show should prioritize emission reduction strategies while capitalizing on advantages when it most viable.

Evaluating the near- and long-term role of carbon dioxide removal in meeting global climate objectives

Communications Earth & Environment, Journal Year: 2024, Volume and Issue: 5(1)

Published: July 15, 2024

Abstract The 6th Assessment Report from the Intergovernmental Panel on Climate Change lacked sufficient land-sector scenario information to estimate total carbon dioxide removal deployment. Here, using a dataset of land-based based scenarios assessed by Change, we show that removals via afforestation and reforestation play critical near-term role in mitigation, accounting for around 10% (median) net greenhouse gas emission reductions between 2020 2030 limit warming 1.5 °C with limited overshoot. Novel technologies such as direct air capture storage scale multi-gigatonne levels 2050 beyond balance residual emissions draw down warming. We reducing fossil fuel deforestation (gross emissions) accounts over 80% until global zero (CO 2 ) independent climate objective stringency. explore regional distributions gross cost-effective mitigation pathways highlight importance incorporating fairness broader sustainability considerations future assessments removal.

Carbon dioxide removal and net zero emissions in Africa: an integrated assessment modelling based on three different land-based negative emission solutions

Environmental Research Letters, Journal Year: 2024, Volume and Issue: 19(8), P. 084021 - 084021

Published: July 2, 2024

Abstract As the remaining carbon budget for limiting warming to 1.5 °C rapidly diminishes, it is clear that, besides decarbonization, world will need remove 100–1000 GtCO 2 from atmosphere by end of century. Yet, Africa, where many removal schemes are planned, remains a ‘blindspot’ in existing studies. There limited understanding trade-offs and synergies associated with within Africa’s energy-land-water system. To address this research gap, we model stylized net-zero emissions (NZEs) Africa 2050, focus on three land-based biological approaches: afforestation/reforestation (AR), bioenergy capture storage (BECCS), biochar. We find that total gross projected reach 1.2 yr −1 when all approaches available, 0.5 relies solely AR. Pursuing NZE only AR or alongside biochar would be most expensive mitigation option but they lead lowest residual fossil fuel industry CO emissions. An 2050 could reduce cropland 30%–40% 2020 depending dioxide deployment strategy adopted. Southern particularly affected, facing significant challenges balancing food security climate goals. The highest increase staple prices occur under only, while availability AR-BECCS-biochar produces rise prices. Our findings highlight balanced region-specific strategies ensure other sustainability goals met.

Research Progress on CO2 as Geothermal Working Fluid: A Review

Energies, Journal Year: 2024, Volume and Issue: 17(21), P. 5415 - 5415

Published: Oct. 30, 2024

With the continuous increase in global greenhouse gas emissions, impacts of climate change are becoming increasingly severe. In this context, geothermal energy has gained significant attention due to its numerous advantages. Alongside advancements CO2 geological sequestration technology, use as a working fluid systems emerged key research focus. Compared traditional water-based fluids, possesses lower viscosity and higher thermal expansivity, enhancing mobility reservoirs enabling more efficient heat transfer. Using not only improves extraction efficiency but also facilitates long-term within reservoirs. This paper reviews recent progress on Enhanced Geothermal Systems (EGS), with focus potential advantages improving exchange power generation capacity. Additionally, study evaluates mineralization effects reservoirs, well impact reservoir properties. Finally, discusses technological developments economic analyses integrating other technologies. By systematically reviewing EGS, provides theoretical foundation for future development using fluid.
