Hydrogen potentially has a crucial role in the U.S. transition to net-zero emissions economy. Learning from large-scale hydrogen projects will boost technological evolution and innovation toward Energy Earthshot. We apply experience curves estimate evolving costs of blue production further examine economic effect on Inflation Reduction Act's tax credits for carbon sequestration clean hydrogen. Learning-by-doing alone can decrease cost Without incentives, however, it is hard reach target $1/kg H
Emissions during a trip often depend on transient vehicle dynamics that influence the instantaneous engine load. Vehicle specific power (VSP) is proxy variable for load has been shown to be highly correlated with emissions. This study estimates roadway link average emission rates diesel-fueled transit buses based mean speeds, using newly defined VSP modes from data gathered by portable emissions monitoring system. Speed profiles were categorized facility type and travel speed, stratified...
This paper examines the cost of CO(2) capture and storage (CCS) for natural gas combined cycle (NGCC) power plants. Existing studies employ a broad range assumptions lack consistent costing method. study takes more systematic approach to analyze plants with an amine-based postcombustion CCS system 90% capture. We sensitivity analyses together probabilistic analysis quantify costs without under uncertainty or variability in key parameters. Results new baseload indicate likely increase...
Coal-fired power plants account for nearly 50% of U.S. electricity supply and about a third emissions CO2, the major greenhouse gas (GHG) associated with global climate change. Thermal also 39% all freshwater withdrawals in To reduce GHG from coal-fired plants, postcombustion carbon capture storage (CCS) systems are receiving considerable attention. Current commercial amine-based require water cooling other operations that add to plant requirements. This paper characterizes quantifies use at...
This study investigates the feasibility of polymer membrane systems for postcombustion carbon dioxide (CO2) capture at coal-fired power plants. Using newly developed performance and cost models, our analysis shows that configured with multiple stages or steps are capable meeting targets 90% CO2 removal efficiency 95+% product purity. A combined driving force design using both compressors vacuum pumps is most effective reducing avoided. Further reductions in overall system energy penalty can...
This study employs a power plant modeling tool to explore the feasibility of reducing unit-level emission rates CO2 by 30% retrofitting carbon capture, utilization, and storage (CCUS) existing U.S. coal-fired electric generating units (EGUs). Our goal is identify feasible EGUs their key attributes. The results indicate that for about 60 gigawatts capacity, implementation partial capture appears feasible, though its cost highly dependent on unit characteristics fuel prices. Auxiliary...
The electric power sector in the United States faces many challenges related to climate change. On demand side, change could shift patterns due increased air temperatures. supply lead deratings of thermal units changes temperature, water and availability. Past studies have typically analyzed these risks separately. Here, we developed an integrated, multimodel framework analyze how compounding climate-change impacts on affect long-term planning decisions system. In southeast U.S., found that...
This study develops an integrated technical and economic modeling framework to investigate the feasibility of ionic liquids (ILs) for precombustion carbon capture. The IL 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide is modeled as a potential physical solvent CO2 capture at gasification combined cycle (IGCC) power plants. analysis reveals that energy penalty IL-based system comes mainly from process product streams compression pumping, while major capital cost components are...
In 2020, the Wyoming Legislature enacted House Bill No. 0200 (HB0200), which requires utilities to generate a percentage of dispatchable and reliable low-carbon electricity by 2030. This state requirement must take into consideration "any potentially expiring federal tax credits", such as Section 45Q credit. study aims examine potential role economic policy incentives that facilitate carbon capture sequestration (CCS) deployment. A unit-level retrofit analysis shows deploying CCS at existing...
The U.S. government is prioritizing clean energy transition due to climate change and security concerns. Low-emission hydrogen gaining attention for its high density low life cycle greenhouse gas (GHG) footprint. This study reveals the interconnection among techno-economics, resource impacts social factors of low-emission production under Inflation Reduction Act incentive in state Wyoming. Supplied with fossil natural electricity from power grid, likelihood emissions less than 4.0 kg...
Parkinson's disease (PD) is a common neurodegenerative disorder. Iron metabolism abnormalities have been reported in PD patients and may contribute to pathogenesis. Our study aimed explore key genes associated with iron patients. Three datasets metabolism-related (IMRGs) were collected from the public database, merged into combined dataset. PD-related differentially expressed (DEGs) obtained intersected IMRGs acquire DEGs (IMRDEGs). Subsequently, IMRDEGs subjected functional enrichment ROC...
Despite considerable effort, there are few large-scale carbon capture and storage (CCS) projects operating commercially in the world today. The importance of CCS to world's long-term decarbonization goals, however, has never been greater. outlooks United Nations individual governments all place reliance on broad adoption technology for both power-generation industrial applications. Recent support includes passage Inflation Reduction Act U.S., U.K.'s Energy Security Bill, investments targeted...
Estimating the emissions consequences of surface transportation operations is a complex process. Decision makers need to quantify air quality impacts improvements aimed at reducing congestion on street network. This often requires coupling and models in ways that are sometimes incompatible. For example, most macroscopic demand land use models, such as TransCAD, TranPlan, TRANUS, produce average link speed vehicle miles traveled (VMT) by road class. These values subsequently used estimate...
