A large portion of life cycle transportation impacts occur during vehicle operation, and key improvement strategies include increasing powertrain efficiency, electrification, lightweighting vehicles by reducing their mass. The potential energy benefits are large, given that 29.5 EJ was used in all modes U.S. 2016, roughly half the spent wheeled majority aircraft is to move We collect review previous work on lightweighting, identify parameters affecting environmental performance (e.g., mode,...
The Ce3+/Ce4+ redox couple has a charge transfer (CT) with extreme asymmetry and large shift in potential depending on electrolyte composition. CT behavior are difficult to understand because neither the cerium structures nor mechanism well understood, limiting efforts improve kinetics applications such as energy storage. Herein, we identify Ce3+ Ce4+ sulfuric acid via extended X-ray absorption fine structure spectroscopy (EXAFS), kinetic measurements, density functional theory (DFT)...
The Ce3+/Ce4+ redox potential changes with the electrolyte, which could be due to unequal anion complexation free energies between Ce3+ and Ce4+ or a change in solvent electrostatic screening. Ce anions screening also affect solubility of charge transfer kinetics for electrochemical reactions involving waste remediation energy storage. We report structures cerium complexes seven acidic electrolytes based on Extended X-ray Absorption Fine Structure, UV-vis, Density Functional Theory...
Long-duration energy storage provides key benefits such as consistent power supply during periods of high demand for grid reliability and flexibility. For environmental benefits, it allows more renewable integration helps reduce reliance on fossil fuels to lower greenhouse gas emission. Lead batteries have the economic potential continue serving an important technology a decarbonized sustainable future given they are earth-abundant, inexpensive, 99% recyclable. Advancing design lead with...
Inexpensive energy storage technologies are critical to meeting rising renewable electricity demand and maintaining grid stability, but there is insufficient capacity meet this demand. Redox flow batteries a promising long durations (>10 hour) method, because they scale efficiently with delivery time compared non-flow batteries. Because of the connection between intermittent renewables, impact on greenhouse gas emissions important consider. Here, we investigate all-vanadium redox battery...
Despite the interest in renewable energy as a substitute for fossil fuels, renewables make up less than 20% 1 of total electrical United States part because their intermittency prevents them from being dominant fraction without storage. 2 The redox flow battery (RFB) is promising storage technology its high-power density and long lifetime, which can be used to address by decoupling customer demand electricity generation. Currently, however, RFBs incur substantial losses during operation at...
The EIA projects that 60% of cumulative capacity additions in the U.S. by 2050 will be renewable electric generating technologies. 1 use intermittent energy electricity grid requires storage. NREL predicts for a scenario which 80% comes from 2050, 120 GW storage would needed, 2 yet as 2020, has only 24 capacity. 3 Redox flow batteries (RFBs) are useful technology ensuring smooth integration into because their long lifecycles and discharge times. RFBs currently too expensive market...
Redox flow batteries (RFBs) are a promising technology for large scale energy storage, including grid-scale storage of renewable energy, due to their longer lifecycles and easier scalability than other, more developed battery technologies, e.g., lithium-ion. 1 Despite nature, RFBs currently too expensive market deployment. For instance, the U.S. Department Energy has reported target capital cost new technologies 150 $/kWh, 2 yet recent reports all-vanadium RFB indicate current is at least...
