Carbon dioxide removal (CDR) is necessary for reaching net zero emissions, with studies showing potential deployment at multi-GtCO2 scale by 2050. However, excessive reliance on future CDR entails serious risks, including delayed emissions cuts, lock-in of fossil infrastructure, and threats to sustainability from increased resource competition. This study highlights an alternative pathway─prioritizing near-term non-CDR mitigation minimizing dependence. We impose a 1 GtCO2 limit global novel 2050, forcing aggressive early reductions compared 8–22 in higher scenarios. Our results reveal that this low pathway significantly decreases fuel use, greenhouse gas (GHG) air pollutants pathways. Driving rapid energy transitions eases pressures land (including food cropland), water, fertilizer resources required negative emissions. these gains come costs greater low/zero-carbon technology decarbonization. Overall, work provides strong evidence maximizing strategies such as renewables, electrification, carbon neutral/negative fuels, efficiency now rather than betting uncertain scaling. Ambitious decade essential prevent offer the best chance successful deep constrained scenario offers robust achieving limited impacts.

Abstract Hydrogen energy is essential to establishing a sustainable and reliable system. The continuously growing demand for hydrogen driven by the challenges associated with greenhouse gas emissions resource depletion. This paper investigates summarizes some intriguing production processes that have evolved from laboratory stages mature commercial applications. analysis of techno-economic, environmental effects investment trends these are included. Currently, dominantly produced methods fossil fuels as feed. These technology relatively account majority world's production, around 99%. However, results in significant carbon emissions. Around 1400 million tons dioxide emitted into atmosphere. To achieve neutral strategy, hydrocarbon needs become clean. Equipping capture, utilization, storage system promising way reduce In addition, schemes zero like electrolytic photocatalysis attracting increasing attention. survey suggest price addition capture equipment ranges 1.47 6.04 USD/kg, which higher than value without additional facility (1.03–2.08 USD/kg). introduction tax expected narrow cost gap between two. Besides, electrolysis remains expensive (6.25–12.2 USD/kg), depending on source cell equipment. high-pressure autothermal reforming technique coupled powered renewable favored global investment. Finally, key opportunities clean discussed this paper. More attention should be paid catalyst blockage or deactivation fuel production. For new zero-carbon method, designing efficient, economical catalysts materials its large-scale application.

Abstract Energy transition scenarios are characterized by increasing electrification and improving efficiency of energy end uses, rapid decarbonization the electric power sector, deployment carbon dioxide removal (CDR) technologies to offset remaining emissions. Although hydrocarbon fuels typically decline in such scenarios, significant volumes remain many even at time net-zero While rely on different approaches for decarbonizing fuels, underlying drivers these differences unclear. Here we develop several illustrative systems a simple structural model show that, given set final demands, assumptions about use biomass CO 2 sequestration drive key how emissions from mitigated. Limiting one resource may increase reliance another, implying that decisions using or restricting resources pursuit objectives could have tradeoffs will need be evaluated managed.
